BACKGROUND OF THE INVENTION
~ Field of the Invention
3 The present invention relates to a slot machine with¦ which games are started by supplyLng game medla such a~ medals or
coins thereto and winnlng dispensation o$ said game media is
conducted if a player wins the game.
Des riPtion of Related Art
In general, a slot machine is vperated by a coin
supplied by a player for a game, the player then operating the
reels of the slot machine so as to rotate and stop the reels. The
slot machine determines whether or not the combination of the
symbols for~ed on the surfaces of the reels corresponds ~o any of
sucaessful combinations in a sta~e in which the reels have been
~I stopped. If it is determined that the player is successful, a
predetsrmined number of winning medals or coins are dispensed.
On the other hand, other types of slot machines have
been known in which the game medium, such as the above-described
coin or medal, is replaced by numerical information stored in a
~ magnetic card or an IC card; the numerical informatlon
! 20 corresponding to a predetermined number of the game media. The
card storing the above-described numerical information is arranged
to be read by a reader provided in the slot machine so as to start
the operation oE the slot machine.
Hitherto, in conventional slot machines there arises a
` problem in that th0 player suffers from a complicated operation in
order ~o supply the game medium to the slot machine since the
- medals or coins serving as the game media are ~upplied to the 810t

machine for every game and the winning dispensation ls conducted i~
at every game if the player wins the game.
Furthermore, since it is necessary for the slot machine
to dispense the winning dispensatLon at every game, it must store
a large number of medals or coins to be dispensed for the winning
dispensation in a hopper or the like provided therein.
On the other hand, the slot machlne of the ~ype in which
numerical data written in a magnet card or the like is used as an
alternative to the game medium is able to overcome the above-
described problem taken place with the slot machines of the typewhich are operated by medals or coins. However, the slot machlne
of the type in which numerical data is used fails to provide the
player with all the excitement of the game since the winning
dispensa~ion is conducted with numerical data. ~;
DE-A-31 39 585 discloses a slot machine comprislng: a) a
game media receiving mechanism for collectively receiving a
multiplicity of said game media for the purpose of continuously
conducting a plurality of games one after the other; b) a winning
determination mechanism capable of storing numerical data which is
formed by accumulating each winning dispensation numerical data
which corresponds to the winning of each respective game in the
case where a plurality of games is played continuously one after
the other; c~ a winning dispensation mechanism. With the winning
dispensation mechanism disclosed in this reference the whole
amount of winning dlspensation can be dispensed if the gambler
actuates a button during the games.

storing numerlcal data is provided. Therein successive winning
dispensatlon is stored.
The object of the invention iB to lmprove the slot
machine such ~hat a higher variety in game playing i~ achieved.
This object is obtained by a slot machlne which is
characterized in that said winning dispensatlon mechanism is
capable of dispensing a desired number of said game media during
the continuation of the games whereas said desired number of said
game media can be less than the number of said game media
corresponding to said accumulated numerical data and said
accumulated numerical data exceeds zero.

DETAILED DE5CRIPTION OF THE INVENTION
Embodlments of the present inventlon will now be
described wi~h reference to the drawings.
Referring to Fig. 1, reference numeral 1 represent~ a
case for the slot machine, the ca~e being in the ~orm of a
rectanyular shape longltudinally elongated when viewed in a

;~o~
front elevational view. There are three display openings
2a formed in the upper portion of a front panel la so that
symbols formed on the surfaces of three reels 2 are shown
through the three display openings 2a. In a portion below
the display openings 2a there is provided an operation
panel 5 in which operation buttons 3a and 3b to 3d for
controlling the start and stop of the reels 2 are provided
therein, an operation switch board 4 consisting of a ten-
keyboard to be described later being also provided in the
portion below the display openings 2a.
Reference numeral 6 represents a receiving tray for
supplying game medium, the receiving tray 6 being disposed
below the operation panel 5. The receiving tray 6 having
an outlet port 6a which is communicated with a passage duct
7. The passage duct 7 has a supply-media counter portion
7a at an intermediate position thereof, the supply-media
counter portion 7a having a counter sensor (omitted from
illustration) so as to count the number of the game medium
which has been supplied to the receiving tray 6.
On the other hand, the lower portion of the front
panel la is arranged to be an opening 8 extending laterally
so that a receiving tray 9 for receiving dispensed game
medium can be set in this opening 8. Reference numeral 9a
represents a receiving tray detection switch capable of

~2 detecting whether or not the receiving tray 9 has been set
properly.
The receiving tray 9 has an outlet port lOa of a
dispensation duct 10 disposed in the case 1 of the slot
j machine so as to bring the outlet portion lOa into the
;; position of the outlet port lOa.
; The dispensation duct 10 has a dispensation-media
counter portion 11 in an intermediate position thereof, the
dispensation-media counter portion 11 being capable of
counting the number of the game media to be dispensed.
The above-described slot machine is a slot machine
designed similarly to conventional slot machines since when
; the start button 3a is depressed after a game medium has
been supplied thereto, the three reels 2 are rotated
simultaneously, and when the stop buttons 3b to 3d are then
selectively depressed so as to stop the rotation of each of
the reels 2, the combination of the symbols formed on the
surfaces of the reels 2 is used to determine whether or not
, a player wins the game, the combination of the symbols on a
;i previously provided winning line being subjected to the
determination.
However, the slot machlne according to the present
'2~ invention i9 structured in a different manner from the
¦ conventional slot machines, the different being lies in a
~ manner for supplying the game media, a manner for playing

,.
c the game, the contents of the game, and a manner for
dispensing the game media when a player wins the game.
Then, these factors will be respectively described.
First, the manner for supplying game media in the slot
machine according to the present invention is arranged in
such a manner that game media of the number for a plurality
of games is collectively supplied prior to a start of a
` play since a plurality of games are successively conducted
without a supply of the game media for each game.
Fig. 3 is a cross sectional view which illustrates a
.; ~ .
mechanism for receiving the game media s~lpplied
collectively.
Referring to Fig. ~, the receiving tray 6 for
¦ receiving the supplied game media is fastened to an opening
lb for fastening the receiving tray 6 in such a manner that
~ the receiving tray 6 is able to be freely laid and stood
`3 via a horizontal pivot 6b, the opening lb being formed in
~ the front panel la. Thus, the receiving tray 6 is laid at
1 the time of the slot machine is used. According to the
prèsent invention, it is necessary for the receiving tray
' to be arranged to be able to be laid and stood. It is -
~ necessary for the same to be able to receive the game
.33` media.
Reference numeral 7 represents the passage duct
through which the game media passes, the passage duct 7
'~ ,..
',

being connected to the game-media receiving opening 6a
connected to a bottom plate 6c of the receiving tray 6 in
the fastening opening lb formed in the front panel la. The
duct 7 being connected to an intermediate tray 7b
comprising the counter portion 7a consisting of a counter
for counting the passing game media and a sensor for it,
the duct 7 being then connected to a circular passage
~omitted from illustration) through which the supplied game
media passes.
Thus, a plurality of game media corresponding to a
plurality of number of games is supplied to the receiving
tray 6. Referring to the example shown in Fig. 3, the game
media supplied to the receiving tray 6 is introduced into
the passage duct 7 by standing the receiving tray 6. The
counter portion 7a of the passage duct 7 into which the
game media has been introduced counts the number of the
game media so as to output the accumulated value to be
described later.
The game media to be used in the slot machine
according to the present invention may be media whose
number can be counted, for example, medals, coins, small
steel balls, or the like. An example in which the balls
are used as the game media will be described hereinafter.
When the game media (balls) has been supplied and then
the number of the same has been counted, the slot machine
. ~ .
.. .. .
~:~
.. ~` 2006~87
,.. .
.~
, ...... .
. according to the present invention is brought into a state
: .;,
in which the slot machine has prepared for the game start
in the following manner.
In the procedure of the game with the slot machine
according to the present invention, there is no necessity
of supplying the game media at every game since the game
media for a plurality of games has been supplied prior to
the start of the game.
However, the number of the game media to be bet for a
game is previously determined to be any of one, two, or
three in the case where the game media is medals. In the
:! case where the game media is balls, it is determlned to be
any of 5, 10, or lS. Therefore, the number of the medals
or the balls for a game can be instructed according to the
present invention. In the case where the number of the
game media to be bet for every game is intended to be an
equal number, a continuous instruction mode can be selected
for the purpose of eliminating the necessity of instructing
the number of the game media to be bet for each of the
games. The number of the game media to be bet is not
ii limited to the description above. It may be determined
optionally.
If a player wins a game during the successive play of - `
the games, the dispensation of the game media is not
conducted at each game. When the successive play of the
, :
:i. !`
~'
~ 2006~387
'.'
''.
games has been completed or the player requests for the
game media to be dispensed, the game media is dispensed.
On the other hand, the slot machine according to the
present invention is the same as the conventional slot
machine in terms of the operation of the reels and the
contents of the game arranged in such a manner that the
three reels are rotated by a player and the rotation of
each of the reels is stopped by the player at an optional
timing so as to subject the combination of the symbols
formed on the stopped reels on a winning line to the
determination whether or not the player win the game.
However, the slot machine according to the present
invention has the reels to be operated in an improved
manner to be described later.
Then, the operation of the game medium and the same of
the reels during the play of the game with the slot machine
according to the present invention will be described with
reference to Figs. 2, and 4 to 6.
In the slot machine according to the present
invention, when game media of the number larger than that
for a game is supplied to the slot machine, the number of
the supplied game media is counted by the counter portion
7.
Referring to Fig. 2, reference numeral 12 represents
an arithmetic portion for processing the number of the game

medla, the arithmetlc portlon 12 comprlsing an addition counter to
which data supplied to the counter portlon 7 is supplled so as to
be added. The arlthmetlc portlon 12 i5 arranged ln such a manner
that data representing the number of medium -to be dispensecl ls
supplied thereto from a game-wlnnlng dispensation slgnal genera-
ting portion 15 to be described later when the player wlns the
game.
; Data to be dispensed when the player wins the game is
formed only when the player wins the game dependlng upon a deter-
mination made ln a game-winnlng determination portlon 13 after the
rotation and stop of the reels 2 (with depresslng the buttons 3a
to 3d). ` .
. That is, when the player depresses the operation buttons :
3a to 3d dlsposed ln the operatlon portlon 5, an operatlon control
portlon 3 of motors 2b of the reels 2 rotates or stops the corres-
~¦ ponding motors 2b.
When all of the reels 2 are stopped, the symbols on the
reels Z displayed through the dlsplay opening 2a are detected by a
symbol-detection portion 13 so as to be sub~ected to a deter-
mination whether or not the player wins the game and a determina-
tion about the wlnning grade in a winning determination portlon
~ 14. If it is determined ln the wlnning determlnatlon portion 14
3 that the player wins the game, dispensation data is transmitted to
a wlnning-dlspenfiatlon slgnal generatlng portlon t5.

On the other hand, a numeral number representing the
number of the game media (the number of the medals or the
balls) to be bet a game is determined so as to be supplied
to the arithmetic portion 12 for processing the number of
:
the game medium, the supplied numeral number being supplied
in the form of data to be subtracted.
According to this embodiment, the number of the game
. media to be bet a game is input by a key formed on the
. keyboard 4 in the operation portion 5. For example, when
the nu~`oer of the game media which can be bet for a game is
determined to be 1 to 3 in the case where the game media is
. medals, or when the same is determined to be 5 to 15 in the
, case where the game media is steel balls, the player
., depresses a medium setting key 4b and a number key 9a
3 representing the numeral number 1 to 3 or 5, 10, or 15, the
medium setting key 4b and the number key 4a being formed on
j the keyboard 4 so as to instruct the number of the game
`~ media.
., .
In principle, the instruction is made for each game.
However, according to an example shown in Fig. 2, the ~ ;
number of the game media which has been instructed can be
; automatically continued by depressing a continuous
` instruction key 4c.
According to the present invention, the collective
dispensation for the winning of the games after the games

66747~22
have been completed and the intermedlate dispensatlon for the same
durlng the continuatlon of the games can be conducte~ by depress-
lng the key 4a on the keyboard 4.
When the dlspensatlon after the games have been comple-
ted is conducted by depresslng a game-end dispensation key 4d.
However, lf there ls no positlve numeral data in the arlthmetic
portion 12, the operatlon of the dispensatlon key 4d is, of
course, invalid.
According to the present invention, the dlspensatlon can
be required durlng the continuatlon of the games. The lnter-
~ medlate dlspensatlon requlrement ls conducted by operatlng the
y numerlcal key 4a, after an lntermediate dispensation number set-
ting key 4e has been depressed, so as to set a desired number of ~ ;
the game medla to be dlspensed, and by depresslng an lntermedlate
dlspensation requlrement key ~f. The lntermedlate dlspensatlon ls
¦ invalld if no numerlcal data ls stored ln the arlthmetlc portlon
~ 12. If the stored numerlcal data ls smaller than the determlned
¦ numerlcal data, the intermediate dlspensation is limited to the
stored numerlcal data.
When the above-described two types of the requlrements
for the dlspensatlon have been conducted regularly, a command of
dlspensatlon ls supplled from the arlthmetlc portlon 12 to an
operatlon-control portlon 17 of an operating solenold of a shutter
16 disposed to a counter 11 of a dlspensatlon duct 10. The dls-
pensatlon command is supplled so as to remain the solenoid 16a of

the shutter 16 disposed to the counter 11 ln the open side durlng
the countlng of the number of the game medla to be dispensed.
: Thus, the shutter 16 is continued to open the passage 10
untll the ma~or portlon of the game media to be dispensed ls dis-
pensed. When the number of the game media to be dlspensed come
closer to a predetermined number, for example the number reaches a
"~
~~ number which ls smaller than the predetermlned number by 10, the -~
:i
;~ shutter 16 lntermlttently opens and closes so as to pass the balls
:~ one by one until lt reaches the predetermlned number. When lt
:! 10 reaches the predetermined number, the passage 10 is closed with
~, the output from the operatlon control portlon 17 so as to malntaln
., ,:
i! the passage 10 to be closed.
j Therefore, the operation control portion 17 causes the
solenoid 16a to close the shutter 16 when the data about the quan-
tlty of dlspensation ~enerated by the counter 11 and the dlspensa-
tion commancl data generated by the arithmetlc portion 12 agree
with each other.
$ The above-described dlspensation may be conducted ln the
¦ form of a printlng formed on a sheet S by a prlnter 18 or the llke
~ 20 which ls indlvidually lncluded ln the slot machlne as an alterna- -~
j tlve to the dispensation conducted wlth the above-descrlbed game
medla.

Referring to Fig. 4, the s:lot machine according to the
present invention is provided w:ith a storage por~ion 21
having a function of temporarily storing a dispensation
signal and of calculating the stored signals at a position
between the winning dispensation signal generating portion
, 15 and the arithmetic portion 12. Furthermore, a re-start
and stop mechanism capable of re-starting a reel which has
been stopped temporarily and of again stopping the same is
provided for the slot machine according to the present
invention. In addition, a service game ~to be called "a
gamble game" hereinafter) performed by the operations of
the reels is provided.
Referring to Fig. 4, reference numeral 22 represents a
re-start/stop circuit (to be called "a re-starting
circuit), 22a represents an operation button which can be
I operated when a trigger signal gT representing a fact that
1, the winning dispensation signal has been supplied from the
~ storage portion 21 to the re-starting circuit 22.
I A re-start signal as which can be transmitted from the
re-starting circuit 22 when the operation button 22a is
depressed and a stop signal ap which can be transmitted
from the circuit 22 when the button 22a is again depressed
can re-start and stop the corresponding motor 2b for the
reel 2 via the portion 3 for controlling the operation of
the motor 2b. When the re-start signal as has been formed,

The symbol for the gamble game must be different from the symbols
for usual games. ;
When the winnlng determinatlon portion 24 for the gamble
game transmlts a winning slgnal, the numerlcal data for the wln-
nlng dlspensatlon signal stored ln the storage portlon 21 ls
sub~ected to a calculation so as to be lncreased twice, three
times, or an optional rate. If the gamble game wlnning deter-
' mination portion 24 transmlts a signal representing blank, the
$ numerical data for the winning dispensation slgnal for the usual
game stored in the storage portion 21 ls cancelled.
,!l As described above, with the slot machine according to
the present invention, if a player wlns a game, the player plays
l the gamble game by a predetermined time on conditlon that the
3 20 player has won the usual game.
It ls optlonal for a player to select the gamble gameafter wlnning the usual gam'e. For example, lfithe player!lmmedi-
ately conduct a usual game after the player has won the usual

game ls cancelled. However, the continuous selectlon of the
above-descrlbed gamble game is limlted. For example, one gamhle
game can be selected when a player wlns a usual game, and only an
additlonal gamble game can be selected when the player wlns the
. j .
gamble game, that ls, number of opportunltles for a player to play
the game dependlng upon the wlnnlng of the games ls llmlted to
twlce. The number of the opportunltles can be prevlously deter-
mlned.
The above-descrlbed usual game and the gamble game are
processed according to a flow chart shown ln Flg. 5.
Referrlng to Flg. 5, when a player depresses the start
button 3a, the three reels 2 are simultaneously rotated, and thus
the usual game is started. Then, when each of the reels 2 ls
optlonally stopped by operating the stop buttons 3b to 3d at a
proper tlminy. When all of the reels 2 are stopped, it ls deter-
mlned by the winning determinatlon portlon 14 whether or not the
combinatlon of the symbols on the wlnnlng llne shown through the
display windows 2a agrees with winnlng patterns. ~;~
When it is determined that the player has won the game,
the wlnnlng dispensatlon data ls supplled from the dlspensatlon
slgnal generatlng portlon 15 to the storage portlon 21, and
slmultaneously, the trlgger gT for the gamble game is supplied to
the re-startlng clrcult 22 from the storage portlon 21 so that the
clrcult 22 ls brought to a state ln whlch the clrcult can be oper-
ated. When the re-start button 22a ls depressed ln thls state,

games~ Therefore, when the play with the slot machine is
completed and the player intended to receive the
dispensation with depressing the dispensation requirement
key 4d, the solenoid 16a is operated since all of the
numerical data in the arithmetic portion 12 is supplied to
the portion 17 for controlling the operation of the
solenoid 16a which is capable of opening the shutter 16 of
the dispensation duct 10. When the solenoid 16a acts to
open the shutter 16, the shutter 16 of the-duct 10 is
opened so that the game media is dispensed. The number of
the game media is counted by the counting sensor lla of the
counter portion 11, the count signal being then supplied to
the operation-controlling portion 17.
The operation-controlling portion 17 subtracts the
numeral values which are successively supplied thereto from :
the numeral value of the dispensation data which has been
previously supplied from the arithmetic portion 12. ~hen
the numerical value of the dispensation data becomes zero, :~
the shutter 16 is closed by the solenoid 16a.
During the play of the games, when a player intends to .~:~
receive dispensation, it is necessary for the player to
operate the keys 4a, 4e, and 4f of the keyboard 4 so that
the player can receive an intermediate dispensation. :
According to the present invention, the game media
supplied through an outlet port lOa of the dispensation
~: ' '

duct 10 to the receiving tray 9 is stopped if the receiving
tray 9 has not been set.
That is, the setting portion 8 for the receiving tray
9 shown in Figs. 1 and 3 is provided with a switch 9a which
is capable of detecting the setting of the receiving tray.
. Therefore, if the receiving tray 9 has not been set, the -~
l outputs from the dispensation requirement keys 4d, 4e, and
4f can not be supplied to the arithmetic portion 12, the
output being transmitted by depressing the keys 4d, 4e, and
4f.
Therefore, the switch 9a is inserted so as to serve as
i
a switch for controlling the operation of the switch
circuit 9b inserted between the dispensation requirement
keys 4d, 4e, and 4f and the arithmetic portion 12. As a
result, if the receiving tray 9 is removed from the switch
9a, the dispensation is stopped even if the dispensation
operation has been conducted. The dispensation is
conducted again on condition that the receiving tray 9 is
again brought into contact with the switch 9a.
As described above, according to the present
invention, the game media to be used in the slot machine
according to the present invention can be collectively
supplied for a plurality of games since the number of the
game media can be stored in the form of numerical data in
the arithmetic portion which is capable of processing the
