, The presenl in~en~ion rclatcs to a data registcr wi~ll a registcr
card selection mecilanism comprising a housing ~hich has a covcr and a base
with a plurality of selector keys which are juxtaposed and superimposed in
rows and a drawer which is under the action of a compression spring and
which is closable by means of a locking mechanism, whereby a large number of
register cards arestacked in said drawer with selection tongues having open-
ings formed in the rear edge portions thereof, said tongues increasing in
size in step-like manner by in each case one opening-containing selection
tongue from one side to the other of the register card with~the first open-
ing to the opposite register card, whereby each selection key is fixed to aswivel arm co~structed as a lever which at its free end carries a card re-
straining pin, whereby the card restraining pins of the swivel levers are
arranged in a row and cooperate with the register cards in such a way that
on depressing a selector key, all register cards located above the register
card associated with this selector key are held back on extending the drawer
by inserting the card restraining pins into the openings of the selection
tongues of the register cards, whilst the selected register card and all the
cards located below it are moved out with the drawer, as well as a device
operable by the swivel levers of the selector keys for unlocking the dTawer
snd releasing the register cards selected by a selector key by forcing out
the unlocked drawer by means of the compression spring and provided with
cams for engaging with cam perforations on the register card.
Various constructions of data registers with selection mechanisms
are known. They comprise a housing for receiving a stack of loose register
cards and a keyboard with correspondingly marked finger keys whose operation
selects thc desired cards. The register cards can contain random information
for subsequent reference in alphabetical order. A known construction of a
data register is made relatively flat in the closed state and is opened by
means of a plurality of keys which are manually opcrated in order to open
the desired register at the desired point, ~hereby making freely visible the
~.151701
Iformation on the c~rds. Thc thus constructc-l data register is also pro-
vidcd with a closing key by mc~ns of ~hich the cover which covers the regis-
ter card can be transferred into the closed position, thereby simultaneously
with the closing of the cover, the raised register cards are automatically
returned to their initial position.
In addition~ a data register is known which comprises a housing
with a drawer for receiving the register cards which is closed by a bolt and
is under the action of a thrust spring and a device for unlocking the drawer
and releasing the register card selected by means of a set key by forcing out
the unlocked drawer by means of the thrust spring.
These known data registers are constructed as standing devices
and are placed on a support. The data register housing can also be provided
with a surface which serves as a support for a telephone if the said housing
is equipped with a drawer which moves the selected register card out of the
housing.
However, it is common to all these data registers that the key-
board comprising a plurality of selector keys is arranged in the front area
o~ the register, whereby the selector keys are juxtaposed in rows. In addi-
tion, the known data registers having relatively large dimensions are known.
In addition, a device for selecting one of the plurality of cards
stored in a housing is known, said cards being selected by key pressure and
horizontally stacked in a drawer arranged in an opening in the front wall of
the housing and moved horizontally into the housing in a closed position and
horizontally out of the housing in an open position in which it can be locked
relative to an initial stress, to which end a latch with a shackla is pro-
vided which is movably secured in the housing and under an initial stress and
engages in a notch in the drawer. In addition, a key lever is provided for
each card which has a rod fixed in pivotable manncr in the housing on whosc
one end is provided a manually opcrable key locatcd outsidc the housing,
whilst at the other end of tho key lever is provided on onc side a shoulder
or unlatching ti~e shac~l~ on operating the key and on the other side a
shoulder which cooperates with thc cards having aligned reccsses in such a
way that on depressing the key all the cards above the card associated with
said key are prevented from moving with the drawer, whilst the selected card
and all the cards located below it are moved out with the drawer.
In ~he case of this known selection mechanism, a plurality of card
- cams corresponding to the number of cards is hinged to the drawer and by
means of attachments arranged at the end of the key lever opposite to the
key, said cams can be moved into an engagement position at the rear edge of
the selected card and the cards located below it on depressing the corre-
sponding keys, whilst the attachment cooperating with the cards is construct-
ed in such a way that it simultaneously engages in a recess of all the cards
located abové the selected card in order to prevent them from moving.
This known selection mechanism has a very complicated construction
in view of the fact that a plurality of card cams corresponding to the number
of cards is hinged to the drawer, which can be brought into the operating
position by attachments on the key levers, whilst the attachment cooperating
with the cards is constructed in such a way that it sumultaneously engages
in a recess o all the cards located above the selected cards in order to
prevent any displacement thereof.
The problem of the present invention is to provide a data register
which has very small dimensions, which is operationally reliable and permits
a completely satisfactory separation of the selected register cards without
significant technical expenditure, accompanied by a minimum areal arrange-
ment of the selector keys.
According to the invention, this problem is solved by a data regis-
ter o the type described herinbefore:
a) wherein the selector keys of thc swivel levers comprisc plate-like,
square or rectangular blanks fixed to the ends thereof, with selector keys
arranged one behind the other iJt any one row having a width which corresponds
` ; liS170~ ~
`D the width of the l~rticular swivcl lever wllich carries thrcc selcctor
keys and are connectcd thercwith in such a way that the selector key facing
the card restraininO pins at thc rcar ends of the swivel lever projects over
the two adjacent swivel levers to the right and the front selcctor key pro-
- jects over the two adjacent swivel levers to the left and the central seIec-
. tor key projects to the right and left over the swivel lever adjacent to
said key on either side,
b) wherein the card restraining pin of each swivel lever:comprises an ap-
proximately U-shaped portion shaped onto the end of the swivel lever with a
leg leading to the selector keys onto whose end is shaped a vertically up-
wardly directed rod which on operating a swivel lever engages from below
into the register card opening or recesses, wherein
c) the drawer comprising a plate-shaped drawer bottom with a front terminal
strip which seals the drawer extension opening in the housing front wall
when the drawer is inserted is made open at the back and on either side and
in its rear edge area has a plurality bf slot-shaped recesses corresponding
; to the number of card restraining pins and having a lengt4 corresponding to
the length of the U-shaped portion on the ends of the swivel levers, whilst
the two lateral drawer limiting walls are formed by two boundary walls shaped
onto the inner wall surface of the housing cover and arranged on either side
of the plate-shaped drawer bottom,
d~ wherein for guiding the swivel lever each swivel lever is provided on
the end carrying the card restraining pin with a vertical slot-shaped open-
ing into which engages a cam shaped onto the inner wall surface of the hous-
. ing cover and is guided in the opening,
o) wherein themechanism for unlocking the drawer comprises a U-shaped
shackle articulated to the cover of the housing and whose web which is at
right angles to the longitudinal direction of the swivcl lever rosts on the
top of the swivel arms and is subject to the action thereof, whilst each
shackle member has a locking cam on its bottom face facing tlle drawer which
llS~
cooperates with a counter-cam shaped onto the drawer in such a way
that on raising the shackle on operating a selector key the locking
cam is disengaged from the counter cam so that the draweris extended
outwards.
In accordance with the present invention, there is provided
a card engaging device comprising a first leg, said first leg being
attached to means for providing movement to said card engaging device,
a second leg extending away from said first leg and a third leg ex-
tending away from said second leg in a direction substantially
parallel to said first leg, a card restraining pin extending from
said third leg toward said first leg.
In accordance with another aspect of the invention, there
is provided a data register with a register card selection mechanism
comprising a housing which has a cover and a base with a plurality
of selector keys which are juxtaposed and superimposed in rows and
a drawer which is under the action of a compression spring and which
is closable by means o a locking mechanism, whereby a large number
of register cards are stacked in said drawer with selection tongues
having openings formed in the rear edge portions thereof, said
tongues increasing in size in step-like manner by, in each case,
one opening-containing selection tongue from one side to the other
side of the register card with the first opening disposed opposite
the first opening of the preceding register card, whereby each
selector key is fixed to one end of a swivel lever which at its
free end carries a card restraining pin comprising an approximately
U-shaped portion shaped onto the end of the swivel lever with a
leg leading to the selector keys onto whose end is shaped a vertical-
ly upwardly directed rod which on operating a swivel lever engages
~S170~
from below into the register card openings or recesses, whereby the
card restraining pins of the swivel levers are arranged in rows and
cooperate with the regis~er cards in such a way that, on depressing
a selector key, all register cards located above the register card
associated with this selector key are held back on extending the
drawer by inserting the rods into the openings of the selection
tongues of the register cards, while the selected register card,
and all the cards located below it are moved out with the drawer,
as well as a mechanism operable by the swivel levers of the selector
keys for unlocking the drawer, said mechanism consisting of a
shackle articulated to the housing and whose web, which extends at
right angles to the longitudinal direction of the swivel levers,
rests on top of the swivel lever and is subject to the action there-
of, and which co-operates with the cam shaped on to the drawer in such
a way that on raising the shackle on operating a selector key the
locking portion of the shackle di.sengages from the cam so that the
drawer is extended under spring tension, said drawer being provided
with cams for engaging with cam perforations on the register cards,
characterized in that each card restraining pin comprises a first
leg attached to said swivel level; a second leg extending away from
said first leg and a third leg extending away from said second leg
in a direction substantially parallel to said first leg, a card
restraining pin extending from said third leg toward said first leg.
By means of the data register constructed according to
the invention, a register card selection mechanism is provided which,
due to the fewer components, namely housing, drawer, swivel levers
with shaped selector keys and shaped card restraining pins and
- 5a -
~iS~70~ ~
drawer unlocking mechanism by means of a swivel shackle operated
directly by the swivel arms on the operation thereof which can be
manufactured in a very economic manner. Due to the small number
of components, assembly is easy and can also be performed by un-
trained staff. The small number of structural parts is particularly
advantageous when carrying out any repairs which may be necessary.
~ue to the special construction and arrangement of the selector
keys relative to their swivel levers, the levers can be housed in
a very small area within the housing because they are arranged very
close together. The arrangement of the card restraining pins at the
ends of the swivel levers in a recess formed in the base plate of
the bottom of the housing permits a shallow construction of the
data register. Even when the selector keys are operated incorrect-
ly, incorrect select;on is not possible because the ends of the
swivel levers carrying the card restraining pins are individually
guided on cams, so that a tilting or displacement of the end areas
of the swivel levers is not possible. No additional devices are
necessary for supporting the swivel arms in their initial position
with spring-operated devices. The swivel lever ends with the card
restraining pins supported on the base plate on the bottom of the
housing. The completely reliable operation of the data register
is also ensured through the swivel arms for controlling the un-
locking mechanism for the drawer being directly operable by the
swivel arms on actuating the same without additional mechanical
devices having to be provided. As the swivelling of each swivel
arm is directly transferred to the swivel shackle, there is
also a direct actuation of the drawer unlocking mechanism,
- 5b -
~51~0~
so that at the time when the card restraining pin engages in the openings of
the register cards remaining in the housing, the drawer is unlocked and is
moved out of the housing with the selective card and the stack of cards
located below the sam~e.
The data register housing is also economic to m~nufacture because a
box type drawer is no longer ne oessary. m e drawer merely consists of a
plate-like blank without side walls and without a rear wall. me side walls
are formed by the limiting walls shaped onto the inner surface of the housing
cover.
Furthermore, the data register housing has very small dimensions
which is also achieved through providing slot-shaped re oesses in the rear end
area of the drawer which correspond to the bent portions carrying the card
restraining pin at the ends of the swivel levers, so that in the drawer inser-
tian, said bent portions rest in the slot-shaped reoe sses. m us, the drawer
can have large dimensions, so that the entire bearing surface of the drawer
,1 is available for the stack of register cards, so that large cards can be used.

The data register shown in Figures 1 to 5 comprises a housing 10
with a box-shaped cover 11 and a box-shaped base 21. Cover 11 and base 21
; are interconnected by means of screw or adhesive connections and are pref-
erably made from plastic. The cover 11 with side walls 13 and 15, front
wall 12 and rear wall 14 has an upper cover plate 16 in which an approximate-
ly square or rectangular opening 17 is formed in the vicinity of front wall
12. The portion of upper cover plate 16 carrying opening 17 slopes in a
slightly desk-shaped manner. The remaining area o cover plate 16 can be
provided with a non-slip layer and have a side which serves as a bearing
surface for a telephone or the like.
~.~.S1701
` Basc ~1 witll sido walls 23 and 25, ~ront wall 22 and rear wall
24 has a base platc 26 ~nd a slot-shapc(~ opening 27 in front wall 22 which
serves to receive a drawer 30.
The base 21 of housing lO receives the drawer 30 which comprises
a plate-shaped drawer base 31 and a front terminal strip 32 which, when
drawer 30 is inserted, seals the drawer removal opening 20 in the front wall
22 of base 21. Drawer base 31 has a cam 33 in its centre and on its top
tFigures 8 and 9). The side walls of drawer 30 are formed by two limiting
walls 19 and l9a which are shaped onto the inside of housing cover 11 (Fig-
ures 10 and 11).
For the purpose of extending drawer 30, a steel spring rod, not
shown in the drawing, is arranged on base plate 26 of base 21 in such a way
that its one free end is connected to the plate-shaped drawer base 31,
whilst the other end thereof is rigidly connected with basé plate 26 of base
21. The action of the steel spring corresponds to that of a thrust spring
which i5 placed under tension on inserting drawer 30 into base 21 of housing
10 so that on unlocking drawer 30 the drawer is extended by means of the
steel spring rod which springs back into its initial position.
A plurality of square or rectangula~r selector keys is arranged
in the area of tpening 17 in upper cover plate 16 of cover 11 of housing 10,
the arrangement being such that the total area formed by the selector keys
fills the opening 17 in cover 11.
In the embodiment shown in Figures 1 and 2, twelve selector keys
40, 41, 42, 43, 44, 45, 46, 47, 48, 49, 50 and 51 are provided which are
correspondingly marked and in fact with the letters of the alphabet in such
a way that selector key 40 carries letters "A,B" key 41 letters "I,J,K",
key 42 letters "S,T", key 43 letters "C,D", key 44 letters "L,M", key 45
letters "Sch", key 46 letters "E~", key 471etters "N,0", key 48 letters
"U,V", key 49 lotters "G,ll", key 50 lettcrs "P,Q,R", and key 51 lettcrs
- 30 "W,Z". The twelve selector keys 40 to 51 are juxtaposed in thrce rows and
:

~rranged one bellind thc other in four rows, so that ~cys 40, 41, 42 and
43, 44, 45 and keys 46, 47, 48 and 49, 50, 51 in each case form one row.
Keys 40 to 51 arc connccted to a num~er of lever~ e swivel arms
60, 61, 62, 63, 64, 65, 66, 67, 68, 69, 70 and 71 corresponding to the num-
ber of keys and on whose ends 60a, 61a, 62a, 63a, 64a, 65a, 66a, 67a, 68a,
69a, 70a and 71a are fixed selector keys 40 to 51, whilst the other ends of
swivel lever 60 to 71 are designated by 60b, 61b, 62b, 63b, 64b, 65b, 66b,
67b, 68b, 69b, 70b and 71b (Figure 7). Swivel levers 60 to 71 are construct-
ed as two-armed levers and are mounted in swivellable manner by means of a
swivel axis of the side walls 13 and 15 of cover 11 in such a way that swivel
levers 60 to 71 are provided centrally with openings which are at right
angles to the longitudinal axis of the swivel levers and through which is
passed swivel axis 80 in such a way that swivel levers 60 to 71 are arranged
so as to swivel freely on swivel axis 80.
In the area of its ends 60b to 71b, each swivel lever 60 to 71 has
a vertical slot-shaped opening 90, 91, 92, 93, 94, 95, 96, 97, 98, 99, 100
and 101 in which engage guide cams 110, 111, 112, 113, 114, 115, 116, 117,
118, 119, 120 and 121 shaped onto the inner wall surface of the upper cover
; plate 16 of cover 11 (Figure 10). The length of guide cams 110 to 121 is
dimensioned in such a way that the free ends 60b to 71b of swivel lever 60
to 71 with their slot-shaped 90 to 101 are guided by means of said cams 110
to 121 so that a lateral displacement of the swivel lever ends 60b to 71b is
prevented. The arrangement offers the further advantage that it is no longer
necessary to fix the swivel levers 60 to 71 on pivot axis 80 to prevent any
displacment.
The selector keys 40 to 51, which comprise plate-shaped square or
rectangular blanks and which are advantageously fixed by means of vertical
webs to the ends 60a to 71a of swivel levers 60 to 71 have a width which is
such that the width formed by the sum of the selector keys 40, 43, 46, 49
and 41, 44, 47, 50 and 42, 45, 48, 51, which are juxtaposed in rows, is no
l~Sl~J~ ~
r~`~ider than tlle total l~idtll formed by the swivcl levers 60 to 71. The
arrangement of thc selector kcys ~0 to 51 on swivel levers 60 to 71 is
explained relative to Fi~ures 15 to 19 by using the exam~le of selector
keys 40, 41 and 42. Selector keys 40 to 42 are arranged one behind the
other in a row and fixed to the ends 60a, 61a and 62a of swivel levers 60,
61 and 62. Selector 1ey 40 is fi~ed to the end 60a of swivel lever 60 in
such a way that the plate-shaped blank of key 40 projects to the right over
the adjacent swivel levers 60, 61, 62, whereby the width of key 40 corre-
sponds to the width of the three swivel Ievers 60, 61, 62. Selector keys
41, 42 also have widths which in each case correspond to the width of the
three swivel levers 60, 61, 62. The central selector key 41 is fixed to
the swivel lever end 61a in such a way that the plate-shaped selector key
blank projects to both sides and the adjacent swivel levers 60 and 62 are
overlapped by it. The front selector key 42 is fixed to swivel lever end
62a in such a way that its plate-shaped blank projects to the left and pro-
jects over the two swivel levers 60, 61 ~Figures 17, 18 and 19). Selector
keys 43, 44, 45 and 46, 47, 48 and 49, 50, 51 are fixed to their swivel
levers 63 to 71 ln the same way as selector keys 40, 41, 42.
The end 60b to 71b of each swivel lever 60 to 71 carries a card
restraining pin 130 tFigure 6). Each of these card restraining pins 130 is
formed by a U-sl-aped portion 140 with webs 140a and leg 140b which is par-
allel to the swivel lever end. The other leg of the U-shaped portion 140 is
formed by the end portion 60b or 61b to 71b of the individual swivel levers
60 to 71.
The free end of leg 140b of U-shaped portion 140 of card restrain-
ing pin 130 carries a vertical rod 130a which constitutes the actual card
restraining pin. The arrangement and construction of the card restraining
pins 130 on swivel lever ends 60b to 71b are such that on operating one
swivel lever by depressing the corresponding selector key the rear end of
the swivel lcvcr is raised, whcrcby simultaneously rod 130a of U-shaped por-
, - 10 -

l~Si~
~ion 140 of thc relcvant swivcl lcvcr is r~ised and as will be explLIined
in greater detail hereinafter cngagcs in thc openings or reccsses on the rear
edges of the register cards of the stack of register cards located in drawer
30, as intimated at 200 in Figure 6.
In order that the data register has a limited height, a recess
27 (Figure 6) is provided in base plate 26 of base 21 in the area of the
bearing surface of U-shaped portions 140 of card restraining pins 130. The
depth of recess 21 approximately corresponds to the height of webs 140b of
the U-shaped portions 140 of card restraining pins 130, w'nereby however the
depth of recess 27 can also be larger. Recess 27 must be constructed in
such a way and the association of swivel axis 80 for swivel levers 60 to 71
must be such that the swivel levers are slightly inclined in the inoperative
position as shown in Figure 6. In this inoperative position, the webs 140b
of U-shaped portions 140 of card restraining pins 130 are supported on the
base surface of recess 27. This construction ensures a perfect engagement
of rod 130a of card restraining pins 130 in the openings in the rear edge
areas of the cards of the stack 200 of register cards. In addition, the
individual rods 130a can be provided with a rear bent portion 130b, but its
surface area must be no larger than the openings provided in the edge areas
of the register cards. This rear bent portion 130b of rods 130 prevent, on
extending drawer 30, any lifting of those cards ~hich are located below the
selected card and are moved out with drawer 30. This construction of rod
130 i5 particularly advantageous in the case of register cards which follow-
ing prolonged use are no longer flat.
In order to be able to extend drawer 30 after operating a selec-
tor key, an unlocking mechanism is provided which is actuated by means of a
swivel shackel 150 (Figures 12, 13 and 14). This swivel shackle 150 is a
U-shaped shackle with legs 151 and 152 and a rod 153 which interlinks said
legs. At the ends 151a and 152a of legs 151 and 152, the swivel shackle
150 is articulatcd to the outer wall surfaccs of the vertical limiting walls
. - 11 -
~151701 r
`9 and l9a, which arc shapcd onto the covcr 11 (Figure 10). Ilowever, the
possibility e~ists of articulating swivel shac~le 150 with its leg ends 151a
and 152a to the inner wall surfaces of side walls 23 and 25 of base 21. The
swivel shackle 150 is fixed in such a way that it can be swivelled about the
swivel axis indicated at 155 in Figure lO. In addition, swivel shackle 150
is arranged in such a way that when the data register is not in use, web 153
of shackle 150 rests on swivel levers 60 to 71 namely in the area of their
ends 61b to 71b. However, the possibility also exists of extending the leg
140b of U-shaped portion 140 of card restraining pins 130 over and beyond
the vertical web 140b (Figure 6). The complete extended portions 140c then
serve as a bearing surface for web 153 of U-shaped swivel shackle 150 lead-
ing to the advantage that the housing 10 of the data register has only a
limited height. On operating a selector key, only a limited lift is then
required for raising the swivel shackle 150.
As shown in Figure 14, the drawer unlocking mechanism comprises
a locking cam 1~6 shaped onto the bottom of each leg 151 and 152 of swivel
shackle 150. Locking cam 156 comprises an approximately triangular body
with an approximately vertical stop face 156a facing the rear ~11 of hous-
ing 10. Counter-camslS7 shaped onto the drawer bottom 31 on either side
thereof engage with stop face 156a. Each of the counter-cams 157 is con-
structed as a triangular body with a vertical edge 157a facing the front of
housing 10.
According to Figure 14, the operation of the drawer unlocking
mechanism is such that on operating a selector key in the direction of arrow
X, the free end of the swivel lever carrying the card restraining pin 130 is
~wivelled upwards in the direction of arrow ~ and simultaneously swivel
shackle 150 is swivelled upwards in the direction of arrow Y. During the
swivelling of swivel shackle 150 in the direction of arrow Y, the two lock-
~ ing cams 156 on legs 151 and 152 of swivel shackle 150 are disengaged from
: 30 thc counter cams 157 of drawer 30 so that under spring tension drawer 30
. - .
. , .
-:,
115~701
`~an be extended in the dircction of arrow Yl. If after cxamining a register
card, drawer 30 has once ;Igain to assume a position within housing 10, it is
inserted counter~to the tcnsion of the spring until the counter-cams 157 and
drawer 30 engage behind the locking cams 156 on swivel shackle 150, whereby
the latter assumes its inoperative position. By inserting drawer 30 into
- housing 10, counter-cams 157 are assisted in sliding past the locking cams
156 by the wedge-shaped guide surfaces 156b and 157b of cams 156 and counter-
cams 157. When on inserting drawer 30, its counter-cams 157 have assumed
their position behind the locking cams 156 of swivel shackle 150, the,latter
moves into its lowermost position due to its own weight or aided by a spring
and thus locks drawer 30.
In order that in the inserted position, drawer 30 offers a maximum
bearing surface fGr the stack 200 of reglster cards, the plate-shaped drawer
base 31 has a number of slot-shaped recesses 160 to 171 corresponding to
the number of card restraining pins 130. The length of each slot-shaped
rocess 160 to 171 corresponds to the length of leg 140b of U-shaped portion
140 o~ each card restraining pin 130, so that in the inoperative position of
swivel levér 60 to 71 the U-shaped portions 140 with their legs 140b extend-
ing in the direction of the front of housing 10 come to rest in the slot-
shapet recesses 160 to 171. Due to this construction, swivel le~ers 60 to
71 are aligned in the inner area of housing 10, so that on actuating a selec-
tor key thé corresponding card restraining pin can engage without any lateral
displacement in the openings on the rear edge areas of the register cards.
The stack 200 of register cards arranged In housing 10 has a num-
ber of register cards 201 to 212 corresponding to the number of selector
ke,ys 40 to 51, whereby card 201 is the uppermost card and card 212 is the
lowermost card in stack 200 ~Figures 20, 21, 21a).
Each card 201 to 212 is provided with a marginal recess and with a
plurality of slot-shaped openings, whereby the marginal reccss extends from
the uppermost card 201 to the lowermost card 212 from the left-hand to the

ight-hand side of thc card, accompanied ~y thc simultaneous enlargcment oP
the marginal rccess by in eacll casc one slot-shaped opening with tho simul-
taneous reduction in the number of slot-shaped openings from the top card
201 to the bottom card 212. As shown in ~igures 21 and 21a, slot-shaped
recesses 201a to 212a are provided in the rear marginal areas of register
cards 201 to 212. Each register card 201 to 212 ]ias one recess 201a to 212a.
In addition to in each case one recess 201a to 212a, each card right down to
the bottom card 212 is provided with a plurality of slot-shaped openings,
whereby the number of said openings decreases by in each case one opening
from the top card 201 to the penultimate card 211, so that finally card 212
has no opening and instead only a single recess 212a which extends from re-
cess 201a of card 201 to the opening in card 211.
In addition to marginal recess 201a, register card 201 has eleven
` openings 220, 220a, 220b, 220c, 220d, 220e, 220f, 220g, 220h, 220i, 220k,card 202 in addition to the double width recess 202a ten openings 221, 221a,

Therefore, the selection of a rcgistcr card takes place in such
a way that on oper~ting a selcctor ~cy by means of the swivellable swivel
lever, the card restraining pin ~itll its rod 130 engages from below into
the recesses and the superimposed opcnings, so that, extending the drawer,
all the register cards are held back which.are located above the selected
card, this being effected by the rod 130a which is passed through the open-
ing, whilst the other card positioned below it can be moved out with the
drawerJ because rod 130 is passed through the recesses below the openings
of the superimposed cards and is therefore unable to hold bàck these cards.
Register cards 201 to 212 are made ~rom cardboard, pasteboard or
the like and can be pro~ided with corresponding line guides, fields and the
like. In addition, each register card 201 to 212 carries those letters
corresponding to the letters of the alphabet which appear on the selector
~ey associated with the corresponding card. Thus, card 201 is provided with
letters "A,B", card 202 with letters "S,T", card 203 with letters "I,J,K",
cart 204 with letters "C,D", card 205 with letters "Sch", card 206 with
letters "L,M", card 207 with letters "E,P", card 208 with letters "U,V",
card 209 with letters "N,0", card 210 with letters "G,H", card 211 with
letters "W,Z", and card 212 with letters "P,Q,R".
As shown in Pigure 20, all the register cards 201 to 202 have a
slot-shaped opening 240 in the centre thereof in which engages the cam 33 on
the plate-shaped draw bottom 31. Cam 33 is also triangular, so that the
cards to be moved out with the drawer are seized by cam 33 and can be car-
ried along, whilst the cards held back by card restraining pins 130 cannot
be carried along by cam 33.
