1 ¦ Background of the_Inventio_
2 ¦ The subject invention is applicable to many types
3 ¦ of gaming devices wherein the player inserts the proper coin
4 or coins and activates a plurality of movable members.
5 1 These members are subsequently stopped in random positions
6 ¦ with a payout being made in response to the degree of corre-
7 ¦ lation between the stopped positions and predetermined winning
8 combinations. While the invention has broader application,
9 ¦ it is described herein for use in a gaming device commonly
10 ¦ known as a slot machine having internal mechanical operating
11 ¦ mechanisms similar to that described in U.S. Patent 3,642,287,
12 ¦ Rotating Reel Game With Masking Shutter, issued on February 15,
13 ¦ 1972, with Lally et al, inventors.
14 I In the device of that patent and other similar devices
15 ¦ relating to permutation and combination apparatus, there is
1~ ¦ provided a plurality of symbol-bearing reels mounted for
17 ¦ rotation about a single axis. The reels are set into rotation
18 ¦ by the player pulling a handle. Thereafter a timing apparatus
19 ¦ stops the reels individually and on a random basis.
20 ¦ Located on the outer periphery of the reels are
21 ¦ combinations of indicia visible to the player. When the reels
22 ¦ have all stopped, there is viewed by the player -the combinations
23 ¦ of indicia written on the auter periphery of the reels which
24 ¦ combinations determine-whether or not a payoff will be received
251 by the player. At the same time the stopped positions of the
2~1 reels are sensed and fed to a calculator which activates a
271 payout sequence if the combinations correspond to those selected
28¦ for payout.
~9¦ Since the winning combinations are determined by the
positions in which the reels come to rest, the payout percentages
31 for the machine are dependent upon the proper operation of the
32 ¦ reel mechanism. Because the reel mechanism is a mechanical
-2-
I ~
635
device, it is subject to abnormalities in operation due to,
among other things, reel imbalance, reel friction and reel wear.
Such inconsistencies in operation result in th.e unpredictability
of the payout percentages which is disadvantageous both to the
player and to the machine owner~ It is the primary object of
this invention to provide a mechanical gaming device having an
electronic control with associated sensing means for operating
the game such that inaccuracies in operation due to mechanical
malfunctions are minimized and the predic-tability of correct
and reliable operation of the machine is greatly enhanced.
Summary of the Invention
In a gaming mechanism of the type having mechanical
mechanisms which are put into motion and the winning combinations
are determined by the stopped position thereof, the combination

the random number generator and for stopping the movable members
; at positions corresponding to those numbers, and means for
. sensing the stopped position of the movable members for generating
a signal for use in calculating the payout to the player.
More particularly, there is provided a game apparatus

12 ¦ Description of the Invention
13 ¦ in FIG. 1 is shown a typical prior art machine in
14 I which the subject invention can be incorporated. Each gaming
15l machine 10 is activated by placing coins into a coin acceptor 11
16 such as that disclosed in U.S. Patent No. 3~998r309
171 Coin Accepting Device, Mandas et al,Issu2d De~er 21, 1976, ~
18 I assigned to the same assignee as this invention. Generally
~9 I such coin acceptors conduct various tests concerning sizet
20 ¦ weigh~ and metallic content of the offered coin, for identifying
1 21¦ the individual coins as being acceptable for playing the gaming
22 machine. ~requently in such devices multiple coins can be
23 paid in succession to multiply the payout and also to increase
24 the odds o~ winning.
If the coins are accepted, display lights (not ~hown)
~6 I are lit to indicate the machine is enabled for playins. Play
27 I is initiated by pulling the handle 12 which sets into rotation
28 a plurality of reels 13 (FIG. 2) which are subsequently stopped
29 ¦ making visible the combinations of indicia 14 on each reel
30 ¦ outer periphery Payouts are determined by whether or not
31 ¦ the indicia on the stopped reels c~mpare with predetermined
32 I winning combinations.

1 ¦ In FIG. 3 is shown a functional b]ock diagram of a
2 typical prior art gaming machine. Therein the coin acceptor 11
3 is shown as receiving the coins. The receipt of the coins
4 ¦ and the activation of the device for play is indicated through
the control line llA by a proper signal to the enabling
6 ¦ device 15 permitting the player to pull the handle 12 of the
7 ¦ device. The handle motion i~ transmitted through -the mechanical
8 linkage 12A to set the reel mechanism 16 in motion. At the
9 ¦ same time the enabling device through the control :Line 17
10 ¦ sets into motion a mechanical random time generator 18 which
11 ¦ activates a reel stop mechanism 19 for stopping the individual
12 ¦ reels in succession. Generally such reel mechanisms comprise
13 three or more individual reels.
14 The random time generator 18 has usually been a
mechanical device which on a random time basis~ actuates
16 suitable linkages to stop the reels in successive order and
17 at random locations. Thereafter through the control linkage 21
18 the reel stopped position detector 22 detects the position
19 of each reel and eeds a suitable signal to the control and
payout logic 24 for calculation of any payout. In one embodiment,
21 the stopped position detector is a mechanical linkage which
22 positions electrical slide contacts (not shown) indicating the
reel position. Prior to -this time and through the conductor llA,
~4 there has been supplied by a coin counter 25 a signal indicative
of the number of coins played in the machine to enable the
26 control 24 to calculate the payout. Thereafter by proper
27 actuation of a coin payout hopper 25 a predetermined number of
28 coins are disbursed in accordance with a signal supplied through
29 the control line 26.
The coins in the payout hopper pass from the coin
31 acceptor 11 along the path 27. The total weight of the coins
52 ln the hopper is detected by the hopper coin detector 28
-5
635
1 which, when the weight is above a predetermined value, actuates
2 a coln diverter mechanism 29 through the conductor 28A to
3 move a deflector 30 into the path of t:he coins and divert
4 ¦ any further coins received through a coin counter 31 to a
S coin drop box 32. More complete details of a typical gaming
6 ¦ device of the type just described can be obtained by reference
r ¦ to the heretofore-identified U.S. Patent No. 3,642,287.
8 Thus the reel stopping positions are determined or
9 affected to some degree by the mechanical condition of the
10 ¦ reel mechanism, that is, the freedom with which the reels
11 turn, since it is obvious that if a reel failed to turn with
12 the actuation of the lever, the player would immediately
13 ¦ recognize that his odds could be greatly enhanced or greatly
14 ¦ reduced depending upon whether winning or losing indicia was
15 ¦ displayed on the stalled reel.
16 ¦ In addition, the payout hopper gross weight is
17 ¦ detected by the typical hopper coin detector 28 and the
18 ¦ diverter mechanism 29 actuated in the present machines during
19 ¦ the period of insertion of the coins. Past experience has
20 ¦ shown that the hopper coin detectors function as weight detectors
21 ¦ and tend to oscillate or chatter when the critical weight is
22 approached to thereby render a lack of control on the count
23 ¦ of the coins because the coin might pass to the hopper or
24 ¦ drop box depending upon the immediate momentary position of the
25 ¦ oscillating divertex. Thus coin accountability is very
2~ ¦ difficult in the present machines thereby requiring that the
27 owners depend only upon a gross count of coins taken from the
28 ¦ repositories and not upon a precise count of coir.s played in
29 each machine indicating the gross number of coins deposited in
30 ¦ the payout hopper and the drop box. The payout hopper of course
31 ¦ is maintained full to accommodate payout requirements while the
32 drop box ser~es as a repository for coins received in excess
-6-
110~635
1 ¦ of the payout hopper capacity. The drop box coins are collected
2 ¦ periodically by the machine owner.
3 ¦ In accordance with one feature of the invention,
4 ¦ there is provided electronic means for generating the addresses
5 ¦ at which the reels are to be stopped,in combination with means
6 for stopping the reels at those respecti~e positions to
7 ¦ substantially eliminate the effect of any mechanical malfunc-
8 ¦ tioning of the reels and reel assembly on the selection of the
9 ¦ stopping position. This aspect of the invention is illustrated
10 ¦ in FIG. 4 wherein components c~f similar operation and functioning
11 ¦ are identified with similar numbers as those in FIG. 3.
12 Thus shown in FIG. 4 i5 a coin acceptor 11, an enabling ¦
13 clevice 15 and a reel mechanism 16~ Coins received by the coin
14 acceptor drop either into a payout hopper 25 or a coin drop
box 32. A coin diverter mechanism 29 positions a deflector 30
to determine the drop path of the coin.
17 The enabling,device l5 is connected by the conductor 34
18 to a random number generator 35. The enabling device functions
19 to close a switch in the same manner as it closes switches for
activating the control logic and also for lighting the various
21 displays (not sho~n) to activate the random number generator.
22 In one embodiment of the invention, this random num~er generator
functions continuously at a generating speed of approximately
24 100 numbers per second on the average~ It operates on an
algorithm such that the probability of repeating itself theo-
2~ retically is extremely small. The generator is set to generate
27 a random number corresponding to each address position or each
28 separate indicia on the reel which in this embocliment is
29 approximately 22 index stop positions. Such random number
generators are well-k~own in the electronics art and need not
31 be of special design. It is the random number generated which
32 determines the stopped position for each reel.

~ llQ(1635
1 For proper stopping of the reel, the instantaneous
2 positions of the reel are detected and for that purpose there
3 is provided a reel position detector 360 One embodiment of a
4 suitable reel position detector is illustrated in FIGs. 6 and 7.
Therein is shown a section of an individual reel 13, which
6 rotates about an axis or center shaft 38. The reel generally
7 comprises a flange portion 39 extending from the rim to the
8 center shaft with a peripherally extending cylindrical section 40
9 carrying the indicia which is read by the player. Rotating
with each reel is a selector disc 41 which cooperates with a
11 stopping mechanism 42 to stop the reel at any one of the 22
12 address positions. The selector disc includes one trigger slot 44
13 for each address position. The stopping mechanism includes a
14 solenoid 45 which actuates a linkage 46 carrying a bar 47 sized
1 to fit within the trigger slot. Thus by energizing the solenoid
16~ tnrougll the leads 48, the bar 47 is driven into one of the
171 trigger slots to stop rotation of the selector disc and the
18¦ associated reel.
lg¦ The reel position detector 36 comprises a light source
or lamp 49 positione~ to one side of the reel 1ange 39 with
Zl ¦ an array of photo detectors 50 positioned in alignment with and
22 ~ on the opposite side of the reel from the light source. Each
23 ~ photo sensor is connected by a conductor 51.
24 ¦ Referring to FIG. 6, each of the 22 sectors outlined
25 I by the dotted lines 53 of the reel is divided into an address
26 I section 54 and a decode section 55 separated by the dotted
27 ¦ lines 56. The address and decode information takes the form of
28 ~ precisely positioned holes,translucent areas or light trans-
29 mitting areas 57 in the disc flange ~ith the number, positioning
and relative location of these holes being dif~erent for each
31 addr~ss.
32 / / / /
-8-
.
~ llVC~ti3S
There is positioned in the photo sensor array 50 a
sensor (not shown~ in alignment with each area in which a hole
3 can be located in the reel flange for coding purposes. Thus
4 as the address area 54 comes into alignment with the photo sensor
array 50 a series of signals is transmitted through the conductor
6 connecting with each photo sensor in alignment with a hole and
7 thereby receiving light from the source 49~ A different voltage
level or signal exists in those conductors connecting with
g photo ~ensors not in alignment with a hole. Thus there is
provided a composite electrical signal corresponding with the
11 address detected and therefore, with the signal position of
12 the reel.
13 In alignment with each address area is a timing slot 58
1 With the alignment of this timing slot with a specific photo
1 sensor in the array provided to detect this slot, a signal is
16¦ transmitted indicating direct alignment of the address coding
1~¦ wlth the photo sensor array and ~hereby indicating that the array
181 should be read at that time. Otherwise if reaa at a different
19 , time the address area might merely be in half alignment with the
photo sensor array and erroneous reading would result~
21 Turning now to FIG. 4, the signal from array 51 is
Z2 transmitted to a comparator 60, Also the comparator receives
23 through the conductor 61 a signal indicating the random number
2~ generated by the generator 35. The comparator can be of any
~5 standard design which receives a plurality of slgnals and compares
~6 the signals to provide an output through the conductor 62 when
27 the signals correspond.
2~ A circuit diagram of the reel motion and position
29 detector 36 is illustrated schematically in ~IG. 8. Therein
are shown three reel motion and position detectors 36, one for
31 each reel 13 of the reel mechanism 17. Photo sensors 62 are
32 eaFh illustrated with the arrows indicating the light which
passes through the openings in the reel flange 3~. The emitters
o~ the photo sensors are all tied toyether such that by applying
the proper signal to one of the terminals X, Y or Z, the photo
sensors of that array will be energized so as to detect light
passing through the associated reel. Thus a signal is transmitted
through each of the conductors 51 corresponding to whether or
not an opening in the reel itself falls between the light source
and the respective photo sensor. This signal is transmitted
along with a timing signal from the photo sensor 63 through the
conductor 63A to the comparator 60. This comparator comprises
a series of AND gates 65 which receive at the other terminal
the timing signal through the conductor 63A. Thus the AND gates
can only conduct at the time the timing slot 5~ is aligned with
its associated photo sensorl assuring that the photo sensor array
is in direct alignment with the address sector of the reel.
Thereafter a signal is transmitted through the AND
gates 65 receiving both the timing and -the photo sensor signal to
an EXCLUSIVE/OR gate 66. At the other terminal of each gate 66
are supplied the signals from the random number generator 35
corresponding with the respective number which is generated.
The signal is thus transmitted to the terminals Ac, B , Cc~ Dc
and Ec such that when the signals correspond, i.e. if no signal
is received at either terminal, or a signal is received at
both terminals/ there is a correlation between the number on the
reel and the number selected by the random number generator.
Of course if any one of the EXCLUSIVE/OR outputs is at the lower
level indicating different signals at the termina~s thereof,
no rise in the output signal will occur at the conductor 67.
When all signals received by the EXCLUSIVE/OR gate 66
correspond/ the signal level on the conductor 67 changes indicat-
ing the comparator 60 has detected a correlation between the random
number generator output and the reel position signaling that the
- 1 0 -
110~i3~ ;
1 reel should be stopped. Thereafter a stop signal output will
2 be supplied at the tarminal 68 which subsequently is transmitted
3 through the conductor 6~ to the reel stop mechanism 19~
4 Both the address and decode photo sensor arrays include
5 ¦ parity to assure integrity of the data. However, to further
6 insure that the correct decode (of symbol) is representing the
7 actual player visual impression of the stopped reels the address
8 uses ODD parity and the decode uses EVEN parity. That is, due
9 to the indexing wheel design only a correctly positioned stopped
reel - with a 5ymbol over "win lines" will be accepted as DECODE
11 data. These parity signals are indicated by the presence of a
12 signal passing through the AND gate 70, the EXCLUSIVE/OR gate 71
13 to the conductor 67. Thus as can be seen, there is provided
14 the schematic for one embodiment of the reel motion and position
detector 36 and the comparator 60 which signals when the reel
1~ ~ mechanism must be stopped to make the address correspond to that
17 selected by the random number generator.
18¦ In accordance with another feature of the invention
19 and as shown in FIG. 6, the trigger slots 44 are positioned to
stoF the reel with the photo sensor array always in alignment with
21 the decode section 5S of the reel. Thus during the adaress
22 readout the photo sensor array is used to detect the address codes
23 on the reel by use of the timing signal supplied by the presence
24 of the timing slot 58. However upon energization of the reel
stop mechanism 19, the toggle bar 47 is driven into the aligned
26 trigger slot 44 for stopping the reel. Because of the specific
27 positioning of each of the trigger slots, the reels are alwa~s
28 stopped with the photo sensor array adjacent the decode section
2g of the reel, which decode section corresponds with the address
section at which the xeel was stopped in accordance with the
31 random number generated. Thereafter the reel stop signal is
32 fed to a reel position recorder 80 (FIG. 4) a:Long with the signals
3 from the conductors 51 corresponding to the photo sensor levels.
635
l As shown in FIG. 8, a reel position reaorder 80
2 recei~es the reel stop signal along with the photo sensor siynals
3 which are passed to a series of AND gates 8l and thereafter
4 to a recorder 82. In this manner the specific signals corres-
ponding to the decode code are recorded. The recorder can be
6 of any usual type but preferably is a RAM (random access memory)
7 of capacity sufficient for recording all of the decode signals
8 from each of the individual reels.
9 The purpose for recording these signals is to permit
checking of the reel position once all the reels are stopped to
11 make sure the reel positions have not been tampered with. With-
out such recording and in prior devices, if access can be gained
13 to the machine interior it is possible to alter the positions of
1 the reels prior to triggering the payout logic thereby obtaining
a higher payout than the original reel position requires. However
18 ¦ in the embodiment shown, as each reel is stopped the decode signal
(FIG. 5)
171 is transmitted immediately through the conductor 84/~oth to the
l8¦; control and payout logic 24A and to the reel position recorder 80.
19 I ~fter all reels are stopped and the control logic is signaled to
initiate payout computations, a comparison is made between the
21 reel stopped decode signals xecorded in the reel position recorder
22 80 and the reel decode signals read immediately prior to the
23 payout computation to ascertain that the reel mechanism has not
24 been tampered with or otherwise moved.
2~ Turning now to FIG. 5, there is shown a further
26 embodiment of the invention. As in the past embodiments, there
27 is provided a coin acceptor 11, an enabling device 15r a reel
28 mechanism 16, a reel stop mechanism l9, a coin diverter mechanlsm
29 29, a payout hopper 25, a hopper full sensor 28, a drop box 32,
a random number generator 35, a comparator 60 and a reel position
31 recorder 80. Each of those components function in the same
3Z ~I ner as in the embodiment of 7IG; 4.
110~635
1 ¦, In addition, there is provided a switch 85 cannected
2 ¦ to receive through the conductor 86 the enabling signal from
3 the enabling device 15 and a signal through conductor lll from
4 ¦ the reel mechanism indicating the reels have been set into
rotation. Both of these signals can be supplied by the closing
6 ¦ of switches in response to the energization of the enabling
7 ¦ device as in present machines and a switch closed by the
8 actuation of the handle 12 causing the rotation of the reels.
With the receipt of these signals the reel position, mechanism
is energized to initiate reel position detection. Energization
11 ¦ of the random number generator is also effected through the
12 ¦ conductor 87.
13 ¦ With energization o the reel position detector, a
14 ¦ signal is supplied to switch 88 permitting the transmission of
a number from the random number generator to the comparator
16 ¦ causing the initiation of a search for that number by the reel
17 position detector. When a comparison is sensed, the reel stop
18 mechanism is signaled to energize the solenoid 45/and stop the'
19 reel. The same signal serves to set a counter 89 at one count,
20 ¦ which counter in turn causes the random number yenerator to
21 close the switch 88 causing another number to be transmitted to
22 the comparator.
~3 ¦ The sequence is repeated for stopping the individual
24 ¦ reels 13 of the reel mechanism until the counter reaches a
predet~rmined count equal to the number of reels in the reel
2& ¦ mechanism. Thereafter through the conductor 90 the control and
27 payout logic are signaled to initiate the payout computation
28 ¦ as in past embodiments. Thus the payout logic is signaled
29 indicating the reel mechanism is now totally at rest, that is,
all of the reels have been stopped.
31 With all the reels at rest, the control and payout
32 logic are energized to calculate any payout due the player
-13-
~ 110~635
1 because of the alignment of the indicia on the reels~ ~he
2 circuit diagram for the control is sho~n in FIG. 9. With the
3 receipt of the all reel stopped signal from the counter 89,
4 a comparator 94 is energized to receive a reel position signal
through the conductor 84 and a reel position recorded signal
6 through the conductor 96 from the reel position recorder 80.
7 These signals are referred to as signal A and signal B and
8 should compare. If they do, a signal is transmitted through
9 the conductor ~7 energizing the comparator 98~ At the same
time the payout logic 99 has already received a coins-played
11 signal through the conductor 100 from the coin acceptor 11~
12 Thus a payout signal calculated as a result of receiving the
13 reel position recorded siynal B through the conductor 96 is
14 fed to the comparator 98 which causes the comparator to supply
1 a hopper enable signal through the conductor 101. Thus the
16¦1 comparator 98 thereafter compares the payout logic signal with
171 a coins paid out count signal received back from the pa~out
18¦ hopper through the conductor 102 and so long as these signals
lg do not compare, a hopper enable signal is supplied~
At the same time through the conductor 104 a coin
21 reject sig~al is supplied to the coin reject mechamism 103 to
Z2 prevent acceptance of any further coins. When the coins paid
23 out si~nal equals the payout signal, the comparator 98 ceases
24 the enable hopper signal. At this point there is supplied
through an inverter 105 a game co~pleted signal which is trans-
26 mitted to the coin acceptor through conductor 106 enabling
27 the coin acceptor to once again receive coins.
28 During this operating period there is received by
29 the control a hopper condition signal through conductor 107
which changes levels when the hopper full sensor 28 senses
31 that the hopper is in ~act full. The sensor preferably senses
32 ¦ the hopper eight and if the weight exceeds a predetermined
I1 110~635
l value, signals that the hopper is full. The game completed
2 signal is fed to an AND gate 108 along with the hopper full
3 signal such that at the end of the game the coin diverter
4 mechanism can be energized to divert the coins from ~alling
into th~ payout hopper but instead be deflected to the coin
6 drop box 32.
Thus in accordance with another feature of the
¦ invention, the coin diverter mechanism can only be energized
9 ¦ at the end of a game thexeby preventing any diversion of coins
10 ¦ during the playing of a game or while coins are being paid
ll ¦ in succession to start a game sequence. Thus by supplying the
12 ¦ coin diverter signal only at the end of the game and by supply- ¦
15 ¦ ing this same coin diverter signal to the coin acceptor which
14 includes a standard coin counter, the coin diverter is only
signaled to change positions at the end of each game and not
16 during the time period when additional coins are being offered
17 to the gaming device. By controlling the coin flow in this
18 manner, there is a positive indication as to which repository,
lg i.e. the payout hopper 25 or the drop box 32, receives the
coins and an accurate count and inventory can be maintained of
21 the coins that are in each of those containers. By controlling
22 the coin flow in this precise manner, a check can always be
23 maintained as to whether or not the coins in the various
24 repositories correspond to the coins played and thereby indi-
2~ cating none have been removed by persons having unauthorized
(FIG~ 5)
26 access to the coin repositories. Also shown in thls embodiment /
27 is a coin return box 110 which receives the coins when the
28 coin reject mechanism is energized and returns the coins to the
29 player. This same coin reject mechanism is also energized by
the reel mechanism signal indicating the reel has been put into
31 motion and the duplication of these signals is merely to assure
32 that ~he player cannot continue to drop coins into the machine
-15-
Zi35
1 ¦ aftex play has started by actuation of the handle 12~ The
21 reel mechanism signal is supplied through the conductor 111.
3¦ Thus in accordance with another feature of the
¦ invention, there is displayed both th~e coins played and the
5 ¦ coins paid out after each game. Accordingly there is suppl.ied
6 ¦ to a coins played and payout display 112 signals indicating
7 ¦ the coins played, the coins paid out and the game completed
8 signal as well as the receipt by the coin acceptor of su~ficient
9 coins to energize the enabling device 15. This display continues
until the initialization of the subsequent game wherein the
11 display is reset. Such displays are well-known and provide a
12 vijual indication that the player has received the required
