PATENTS ACT 1990 COMPLETE SPECIFICATION FOR A STANDARD PATENT Name of Applicant: Actual Inventors: Address for Service: Invention Title: Aruze Co., Ltd.
TAMAKI, Masami DAVIES COLLISON CAVE, Patent Attorneys, 1 Little Collins Street, Melbourne, 3000 Coin-sending device The following statement is a full description of this invention, including the best method of performing it known to us.
Q:\OPER\ARL\MAY\2534496 140.DOC 28/5/02 P OPER Arl "l61-5'9.4 Nd-2 I I -1A- The present invention relates to a coin-sending device which is applied in various types of game machines (such as a "pachinko" type of slot machine called or romanized as "Patisuro" and having rotatable reels, and the conventional slot machines and pachinko machines, etc.), various vending machines provided everywhere, automatic money-transfer machines and coin-discrimination machines used for example in banks, or the like, so that coins (including special metal discs called "medals" and usual coins usable for those machines) inserted in a lump in the machines are each sent one by one sequentially to a predetermined process.
A most typical and normal type of coin slot J of the pachinko type of slot machine P is, as disclosed in Examined Japanese Patent Application No. Hei 6-73563 (1994) and as shown in Fig. 23 annexed hereto, provided in the form of a slit-shaped opening into which each of coins M can be put one by one. This means that players place coins into the slot one by one with their hands. Inserting coins one by one is troublesome for the players. Coins inserted are received by the machine one by one sequentially and sent to the further stages. Thus, a coin-selection (or P OPER Al I 93p dll-: 10 I -2discrimination)device Cl for determining true and false coins may be provided purposively at a point on an initial stage in the coin-sending course corresponding to the direction of the pull of gravity and above the coin-payout device H.
To mitigate the trouble of players inserting coins one by one, some machines recently given attention use a wide tray W for inserting coins in one lump, so that players can place a number of coins M all together into the machine at a time. A lump-insertion tray W is shown in Fig. 23 and is used jointly together with the coin slot J, which is for inserting coins one by one. Coins M inserted in a lump from the wide tray W need to be first lined and sent one by one sequentially by a coin-sending device F, which is provided below the wide tray W in the direction of the pull of gravity, to a coin-selection (or discrimination) device C2 disposed underneath the coin-sending device F in the direction of the pull of gravity and is above the coinpayment device H.
In Fig. 23, K designates a panel by the rotatable reels, O a coin-payout opening, E a payout tray, and N1 a coin-sensor disposed under the coin slot J and N2 a coinsensor on a coin-passage extended from the coin-sending device F.
P OPER Adrl _I -9S sp dc-2' 10 1 -3- The disadvantage of this arrangement is that to add a lump-insertion tray W to the machine requires the coinsending device F to be additionally provided with the coinselection device C2. This results in the problem that the lump-insertion tray W must be located in a higher position than the coin slot J, at the upper part of the panel K. This is because receiving, paying out and selecting coins are performed by use of gravity and a drop or fall from the inlet of the coin-insertion part to the coin-payout device must fully ensure that coins sequentially flow smoothly in the machine from the upper part to the lower part. Hence, it is difficult and troublesome for players sitting on the seats in front of the game machines to place coins in the lump-insertion tray W. Thus, this countermeasure for mitigating the trouble of players inserting coins one by one becomes useless or futile.
It has been proposed in Unexamined Japanese Patent Application No. Hei 2-57284 (1990) to locate the lumpinsertion tray W at the same height as the coin slot J. In this case, the drop from the lump-insertion tray W to the coin-payout device H is not sufficiently long for coins to be individually discriminated, leading to problems of the coin-passage being jammed by coins and a coin-reservoir bucket in the coin-payout device H being reduced in size to P:\OPER MI\76175-98 di pgS.doc-23()5A12 -4reduce the number of coins to prevent jamming.
Moreover, since the coin-selection device C2 and the coin-sending device F are separate components, a larger number of parts are required to that extent and incurs higher costs to manufacture such machines. As an additional passage connecting the coin-sending device F and the coinselection device C2 is also required, the whole machine becomes complex in structure and larger in size, leading to the problem of reducing the number of machines that can be placed in available floor space.
Accordingly, one aspect of the present invention provides a coin-sending device comprising a reservoir for storing a number of coins and a rotary disc for sending the coins stored in the reservoir sequentially one by one to a passage, wherein the passage includes a forcible transfer portion in which a transfer force of the rotary disc is applied to coins sent from the rotary disc, and a coinselection part is provided on the forcible transfer portion to determine or discriminate true and false coins and remove false coins from the passage, wherein the coin-selection part is provided with a coin-removal opening smaller in width than a diameter of true coins and a pair of coinsupporters face the opening and extend along the passage to support an outer peripheral part of a true coin, and wherein one coin-supporter comprises a movable member which changes the removal opening between a state of the opening width smaller than a diameter of true coins and another state of the opening width equal to or larger than the diameter of true coins.
The arrangement of the coin-selection part having a coin removal opening smaller in width than a diameter of P:AOPERWArI\76175-98 div pgs.dc.-23/O5J2 true coins and a pair of coin-supporters which face the opening and extend along the coin-passage to support the outer peripheries of true coins allows the coin selection part to be manufactured in a simple and efficient manner.
As one coin-supporter comprises a movable member which switches the states of widths of the removal opening between that being smaller than the diameter of true coins and that equal to or larger than the same, this allows, for example, all of coins in the coin-reservoir, no matter whether they are true or false ones, to be returned to players.
The forcible-transfer portion of the passage may be formed partially on the passage other than on the whole thereof. False coins can be removed from the passage, for example, by falling or the like.
Preferably, a true-coin sensor is provided for detecting true coins which have passed the coin-selection part. This allows processes after discrimination such as the counting true coins and the recognition of passing or non-passing of true coins to be performed accurately without errors.
It is preferred that the passage includes a recess which is formed between a base member and a cover member layered thereon and has a depth enough to receive the thickness of coins. This allows the whole device to be simple in structure, and flat or* smaller in height. The base member and cover member may be layered directly to each P:OPERArm76175-98 div pgs.doc-23/0S)2 -6other or have an intermediate member interposed between them.
Preferably, the movable member is mounted on a swing member which swings around a fulcrum by a drive means. This enables the coin-supporter comprising the movable member to have a simple structure. The swing member and the movable member one coin-supporter of the pair coinsupporters) may be formed integrally with one another, rather than separate to each other.
Preferably a coin-scoop means is formed at a junction between an end of the removal opening and the passage. This P OPER'ArI'l"5-')l Sp~ doc.-271;llI -7allows true coins discriminated at the coin-selection part to be smoothly transferred to and received by the passage.
Preferably, a coin sensor is provided for detecting coins positioned on the passage before being introduced into the coin-selection oart. This allows the coin-selection part to detect idling of the rotary disc.
Preferably, an overflow guide is provided with the reservoir for causing coins excessively stored therein to overflow in a determined direction. This allows coins which exceed the capacity of the reservoir to be transferred from the reservoir.
Preferably, the whole device is slanted with respect to the horizontal plane -with an outlet of the passage facing downwards. This allows true coins to be smoothly taken out of the passage. An angle a of slant of the device may be over 450, preferably 450 or less, for example, about Preferably, the whole device is incorporated in a game machine which has a lump-insertion tray, a coin-payout device and a coin-payout opening in such a manner that an inlet of the reservoir communicates with the tray, an outlet of the passage is connected to a P:\OPER ArI\76173-98 di\' pgs.dc-23 AS12 -8payout device and the removal opening at the coin-selection part is connected to the coin-payout opening. Thus, the coin-insertion into the game machine can be readily and easily carried out.
Preferably, the coins placed in the reservoir can be seen from the outside when the coin-sending device is installed in the game machine. This allows the number of coins stocked in the reservoir to be approximately determined from the outside of the game machine.
Another aspect of the present invention provides a coin-sending device comprising a reservoir for storing a number of coins and a rotary disc for sending the coins stored in the reservoir sequentially one by one to a passage, wherein the passage includes a forcible transfer portion in which a transfer force of the rotary disc is applied to coins sent from the rotary disc, and a coinselection part is provided on the forcible transfer portion to determine or discriminate true and false coins and remove false coins from the passage, wherein the whole device is incorporated in a game machine which comprises a lumpinsertion tray, a coin-payout device, and a coin-payout opening, in such a manner that an inlet of the reservoir is connected to the tray, the outlet of the passage is connected to the coin-payout device, and the coin-removal opening at the coin-selection part is connected to the coinpayout opening, and further comprising a coin-sensor for detecting coins inserted into the lump-insertion tray and a control means for starting the rotary disc in a manner corresponding to an output of the sensor.
P:OPER\Ar1\76175-98 div pgs.doc-23A)5A)2 -8A- This aspect of the invention allows a coin-sucking operation to be automatically carried out when coins are placed onto the lump-insertion tray.
Preferably, there is included a control means for stopping the rotation of the rotary disc in response to operation of coin-insertion switches operated for each play.
Thus, when a player starts the game in the midst of the automatic coin-sucking operation, the automatic coin-sucking operation is stopped to allow the player to concentrate on the game, and the state of credit of coins is made apparent.
Preferably, there is provided a coin sensor for detecting coins sent from the rotary disc and there is P OPER'ArlI7617; ~p doc-27I IAI -9included a control means which stops the rotary disc when a non-detecting state of the coin sensor during rotation of the rotary disc continues over a predetermined time interval. Thus, the automatic coin-sucking operation can be ended automatically corresponding to the absence of coins remaining in the reservoir. The coin sensor may use two sensors, each separately detecting true or false coins after discrimination and divergence of true and false coins, the coin sensor being separate to the sensor provided before the coin-selection part for detecting coins positioned on the passage.
Preferably, there is provided a manual-storing switch and there is included a control means for starting the rotary disc according to whether the switch is turned on and stopping the rotary disc according to whether the switch is turned off. Thus, coins stored in the reservoir are subject to the sucking operation within a player's discretion.
Preferably, there is included a control means for stopping rotation of the rotary disc according to inactivation of a game-start switch operated in each play.
Thus, when the game is started during the manually-operated sucking operation, the sucking operation is stopped to allow the player to concentrate on the game and the correlation P OPER A~N'l .'9X pr d-27/11L I between the state of credit of coins and the results of the game such as wins, etc., is made apparent.
Preferably, there is included a control means for stopping rotation of the rotary disc when the number of true coins taken out of the outlet of the passage to be credited reaches a predetermined number. Therefore, the number of coins to be preliminarily credited in the machine for a number of plays is kept from exceeding a set limit, thereby limiting playing time on the game. The predetermined member of coins entered in credit may be about fifty.
Preferably, the coin-selection part is provided with a forcible-discharge mechanism which causes all of coins to be discharged into the removal opening according to activation of a settlement switch. This allows the game to be stopped at a players' discretion even when coins inserted are still remaining in the reservoir. The forcible-discharge mechanism may have similar structures to that described in relation to the coin-selection part. For example, the forcible discharged mechanism may have a removable opening smaller in width than a diameter of true coins and a pair of coin supports which face the opening and extend along the coin passage to support the outer peripheries of the true coins. The forcible discharge P OPER.All 5-P doc-21 I;I -11mechanism may also have a movable member located on one coin supporter which switches the states of widths of the removal opening between that being smaller than the diameter of true coins and that equal to or larger than the same. The forcible-discharge mechanism may also have the movable member mounted on a swing member which swings around a fulcrum by a drive means.
The main object of preferred embodiments of the present invention is to provide a coin-sending device which enables coins to be well lined up and discriminated at the same point, so that the coin-sending device when mounted in the foregoing various machines mitigates the problem of restriction of available inner spaces of the machines for mounting the coin-sending device, and reduces the size and complexity of the machine structures.

Fig. 1 shows a game machine 8 which is the pachinko type of slot machine incorporating a coin-sending device 100 according to a preferred embodiment of the present invention. The pachinko type of slot machine is a slot machine having the same height and width as those of a frame of the pachinko machine. Coins referred to herein employ metal discs (called "game medals"), for example, of 24.6 to 25.5 mm in diameter and of 1.4 to 1.8mm in thickness. A casing 800 of the machine is provided at the front side with P OPER Arl 7,l5-9;s np do-27A(I Ill -14an indicator 8A showing the various states of play of the game, an allotment panel 8B, a reel-part panel 8C, a part 8D for mounting switches, a waist panel BE, a front-speaker panel 8F and a coin-tray 8G.
Part 8D has a lump-insertion tray for inserting coins in a lump, the casing 800 housing at its lower part a coinpayout device 72 having a coin bucket 721 and a coindischarge part 722, and the coin tray 8G has a coin-payout opening 73 at the inner side. The inlet of a reservoir 1 in the coin-sending device 100 is connected to the tray 71, an outlet 202 of a passage 2 is connected to the coin bucket 721 and a removal opening is connected at a coin-selection part 4 to the coin-payout opening 73. A coin-sensor 9 for detecting inserted coins is provided inwardly of the lumpinsertion tray 71. The arrows in Fig. 1 show the flow of coins.
As seen in Fig. 2, three mechanical reels 8L, 8M and 8R have on their respective outer peripheries figures, such as "cherries" and "oranges". Reels 8L, 8M and 8R are housed inside the reel-part panel 8C. When the reels are stopped, three figures are seen on each reel. The number of the figures on each reel is about twenty one (21) Provided on the switch-mounting part 8D are coininsertion switches (or coin-use switches) including a 1-bet P OPER ,ri 't I-5-9S spcdo-26 1001 switch 81 for when a single coin is used to play, a 2-bet switch 83 for when two coins are used to play and a max-bet switch 83 for when three coins are used to play (at maximum). Judgement lines of the reels become valid according to the number of coins used or inserted. Namely, when a single coin is used or inserted, the central judgement line L1 across reels 8L, 8M and 8R becomes valid; when two coins are used three judgement lines become valid, the upper and lower lines L2 as well as the central one Li; and when three coins are used five judgement lines including the slant lines L3 become valid. Indication lamps El to E3 are lit corresponding to specific judgement lines which become valid.
The game is started by moving up or down a game start switch 80 comprising a lever, a coin or coins having been bet by means of the bet-switches, whereby the three reels 8L, 8M, 8R start rotating simultaneously. The reels can be separately stopped by pushing stop buttons 8e, 8m and 8r corresponding to the respective reels, and winnings (and losing) and the number of coins to be allotted corresponding to winnings are determined according to a combination or combination(s) of the foregoing figures aligned on the valid judgement line(s). Where the stop buttons are not operated, the reels are forcibly stopped about 40 seconds from the P OPER IArl dmoc2/i ILIII 16start of the game.
In Fig. 2, the reference numeral 84 designates a settlement switch for switching between a credit state, in which coins are credited to players or preliminarily memorized, with a predetermined upper limit of 50 coins, for a play or plays about to be started or occurring afterwards, and a settlement state in which the credit and coins remaining in the reservoir 1 are paid out. The reference numeral 70 designates a manual storing switch for allowing the coin-sending device 100 to be activated manually to cause coins to be sucked into and credited in the machine.
The reference numeral 710 designates a transparent plate through which coins stored in the first-side reservoir 1 can be seen from the outside.
As seen in Fig. 3, the coin-sending device 100 is provided with the reservoir 1 including a cylindrical member 11, a base member 21 and a cover member 22 layered thereon between which a passage 2 is defined and a rotary disc 3 is accommodated, and a drive motor 300 and a reduction gear mechanism 310 for the rotary disc 3. The cylindrical member 11 is fixed on the upper part of the cover member 22 by means of a connecting flange 23. The cylindrical member 11 has an overflow guide 10 which is a cut extended in a predetermined range of angle in P OPER Arl'7615;-X Sl do-2i I.I" 17the upper part of the cylindrical member 11 for allowing any excess of stored coins M over a storing limit about 100 coins to overflow in a predetermined direction to the coinpayout opening 73. The coin-sending device 100 is incorporated in the game machine 8 such that with an outlet 202 of the passage 2 facing downwards, the whole device is slanted at an angle ct (250) with respect to the horizontal plane HP.
As seen in Fig. 4, the rotary disc 3 includes a boss 31 connected to an output shaft 301 in association with the motor 300, a disc body 32, a coin guide means 33 in a truncated conical shape swelling upwards centrally of the disc body 32, three coin-holes 34 around the coin guide means 33, a tubular guide 35 projecting toward the reservoir 1, an annular flange 36 which is almost flat and extends on the outer periphery of the disc 3, three coin-sending means 37 which project on the rear surface of the disc 3 and are disposed between adjacent holes 34, and three coin-transfer means 30 which project on the same rear surface and are apart from the coin-sending means 37 at a predetermined phase difference. The rotary disc 3 is formed by integral molding using synthetic resin such as polyacetal. The rotation rate of the rotary disc 3 is about 70 rpm.
P OPER'ArII'7:(-'.I s~doc2 i I -18- As seen in Fig. 5, any coins larger in diameter than the normal true coins TM do not fall through a tapered part 341 formed at the inlet side of the coin-holes 34 to thereby be expelled at the inlet part. Also, any coins larger in thickness than the true coins TM when fall in the hole 34 cannot pass a coin-releasing point 342 near the hole 34 to be removed at the outlet part of the hole 34. In any case, larger non-standardized coins are not sent to the secondside of the rotary disc 3. The coin-holes 34 have the same function as that provided by the opening slit of the conventional one-by-one insertion of coins being set in size according to standardized coins.
As seen in Fig. 4, the base member 21 is provided thereon with the passage 2 having an arcuate portion 200 extending along the outer periphery of the rotary disc 3. A coin M sent from the rotary disc 3 is received by the coin transfer means 30 at its front part 38 (which is narrowed or concaved) to be guided and transferred on the second-side passage 2. A forcible-transfer portion 20 of the passage in which the transfer means 30 exerts a transfer-force on coins occupies almost the entire area of the passage 2. The passage 2 includes, as shown in Fig. 6, a recess 201 which is formed between the base member 21 and the cover member 22 to have a rectangular cross- P OPER.Ad 71?'i75.lX pdo.-27iI lllI -19section having a height enough to receive the thickness of coins.
A coin-selection part 4 is provided as shown in Fig. 4, on the way of the forcible-transfer portion 20 in the passage 2, which discriminates true coins TM and false coins IM smaller in diameter among coins which sent from the rotary disc 3 and not excessively larger in diameter and thickness. The coin-selection part 4 is provided with a coin-removal opening 40 slightly smaller in width than the diameter of true coins TM, a first coin-supporter 41, which includes a narrow coin-supporting part positioned at the outer side of the coin-selection part 4, a second coinsupporter 42, which forms a movable member 400 positioned inwardly, the coin-supporters 41 and 42 facing the coinremoval opening 40, and a coin-scoop means 43 disposed at the end of the coin-removal opening In Fig. 4, the reference numeral 211 designates a coin guide which extends circumferentially except a coin-sending point 210 from the rotary disc 3 to the passage 2. The reference numeral 6 designates a coin sensor which comprises, for example, a reflection type photo-sensor for detecting coins before being introduced to the coinselection part 4.
As seen in Fig. 7, the second coin supporter 42 P OPER Arl 6175-.9X spc d-27, Id1I1 provided at the coin-selection part 4 is mounted to a swing member 403, which swings around a fulcrum 402, and can be switched between a usual selection state (Figs. 4, 11 13, 16 and 17) and an all-coin retrieval state (Figs. 18 and 19) by a solenoid type of drive means 401 having a rod 404 which moves forwards and backwards following electricity being turned on and off.
As seen in Fig. 8, when the rotary disc 3 rotates counterclockwise (indicated by the hollow arrow), each coin M which has fallen to the bottom of the hole 34 shifts slightly outwards from the hole 34 to abut against the inner periphery of the coin guide 211 and be transferred by the coin-sending means 37. When the coin reaches the coinreleasing point 210, at which the coin guide 211 terminates, the coin is released in the direction indicated by the solid line a by a centrifugal force to the passage 2. Release of the coin M is smooth since the plane on which the coin is transferred along the coin guide 211 is level with the plane of the passage 2. The coin-transfer means 30 has at its rear side. a narrow concaved part 39 by which the coin M is guided to the passage 2 without being prevented from being sent from the rotary disc 3.
As seen in Fig. 9, a coin M which did not shift from P OPER II 9S Pd-o .I'H I -21the bottom of the hole 34 outwards.to the coin guide 211 and has been carried by the coin-sending means 37 as illustrated can be helped going out by an anti-lock mechanism 220 formed near the end of the coin-sending point 210. In detail, the anti-lock mechanism 330 comprises a fulcrum 221, a linkage member 222 swingable around the fulcrum, a pin 223 projecting on the linkage member, an elongate hole 224 for the pin 223 and a spring 225 for biasing the linkage member.
When the coin M, carried by the coin-sending means 37, is brought into contact with the pin 223, the pin's counterclockwise restoring force (indicated by the arrow b) causes the coin M to escape from the coin-sending means 37 outwards (indicated by the arrow The anti-lock mechanism 220 does not allow a false coin having nonstandardized larger thickness to escape from the hole 34.
Locking of the rotary disc 3 can be prevented by moving the pin 223 back at a maximum distance from coin M in a hole 224.
Where a coin M is not sufficiently away from the coinreleasing point 210 and stops on the way as shown in Fig.
one end of the coin-transfer means 30 flicks the coin M circumferentially (indicated by the arrow causing the coin M to be sent outwards (indicated by the arrow e) without returning inwardly due to hindering by the coin- P OPERAd 7 I IN dc-27/1 II1 -22sending means 37 and pin 223 of the anti-lock mechanism 220.
Fig. 11 shows the coin M sent to the passage 2 and forcibly transferred by the coin-transfer means 30. The coin M passing the coin sensor 6 is detected by the sensor.
Coins M then pass the coin-selection part 4 as seen in Fig. 12.
As shown in Fig. 13, true coins TM in a standardized size are supported at their respective diametrically opposite lateral ends by the first and second coin supporters 41, 42 to be conveyed without falling in the coin removal opening 40. The upper surface of coins M closely face a rear surface of the cover member 22, so that there is no risk that the coins are turned over. True coins which tend to sink down or slant at their front side at the end of the coin-selection part 4 can be supported or received by the coin-scoop means 43 as shown in Figs. 14 and 15 to be smoothly transferred to the passage 2.
As shown in Fig. 16, a true-coin sensor 5 is provided downstream of the coin-selection part 4. The sensor comprises a detecting unit 50 using a transmission type photosensor, a linkage member 52 swingable to move towards and away from a detection optical path 51, a fulcrum 53 for the linkage member 52, a pin 54, an elongate slot 55 for the P OPER Af -bI -9S p dC-o Ip±l -23pin 54 and a spring 56 for biasing the linkage member. True coins TM sorted after the discriminating operation are brought into contact with the pin 54 to move the pin 54 backwards counterclockwise (indicated by the arrow f), causing the linkage member 52 to move across the optical path 51 and so detect a true coin, adding one to the credit accordingly. After passing the sensor 5 the true coins TM are discharged from the outlet 202 of the passage 2, as indicated by the arrow g, to the coin bucket 721 of the coin payout device 72.
As shown in Fig. 17, when a false coin IM smaller in diameter than true coins is introduced to the coin-selection part 4, the false coin is not supported at both lateral ends by the first and second coin supporters 41 and 42 and falls in the coin-removal opening 40 (indicated by the arrow h) to the coin payout opening 73.
As seen in Fig. 18, when the electricity is turned off at the solenoid type drive means 401 provided at the coinselection part 4, the rod 404 (which retracts when the electricity is turned on) is stretched to shift the second coin supporter 42 forming the movable member 400 (in the direction indicate by the arrow i) to make the width of the removal opening 40 larger. When the rotary disc 3 rotates in this instance, all coins including true coins TM and P OPER V 1-01 -9 pc dc -T2 10 (11 -24 false coins IM can be retrieved from the coin payout opening 73 through the removal opening 40 (as indicated by the arrow j) as shown in Fig. 19.
As seen in Fig. 20, the game machine 8 including the coin-sending device 100 is controlled by a control means 900 provided with a microcomputer CPU, read only memory (ROM) and random access memory (RAM). 901 is a clock pulse generation circuit, 902 a frequency divider, 903 a random number generator used in lottery for generating specific features of winnings, and 904 a random number sampling circlit.
Connected to the input side of the CPU are the inserted-coin sensor 9, true-coin sensor 5, coin sensor 6, manual-storing switch 70, game start switch 80, coininsertion switches (or coin-bet switches) 81, 82 and 83, settlement switch 84, a stop signal circuit 905 from the stop buttons 8e, 8m and 8r, a position detector circuit 906 for the reels 8L, 8M and 8R, and a payout finish signal circuit 907 for the coin payout device 72.
Connected to the output side of the CPU are the objects to be controlled, the drive motor 300 for the rotary disc 3, solenoid type drive means 401 at the coin-selection part 4, a drive circuit 908 for the stepping motors SL, SM, SR for the reels 8L, 8M and 8R, a hopper drive circuit 909 P OPER All -01* ipc 1o1-2 1l Io for the coin-payout hopper housed in the coin payout device 72, an indicator drive circuit 910, and a sounds generation circuit 911.
Fig. 21 shows control by the control means 900 from the start of the game to the end thereof.
Where the settlement switch 84 is turned on to request coin-payout (the step Si), coins corresponding to the credit are paid out from the coin payout device 72 to the payout tray 8G (S2) and coins remaining in the first-side reservoir 1 are then paid out to the tray 8G and the control returns to the initial state A. Upon payout of the residual coins, the rotary disc 3 is rotated with the solenoid type drive means 401 being turned off.
Where the settlement switch is not turned on, when any of the coin-insertion (or bet) switches 81, 82, 83 is turned on a coin or coins in number corresponding to that switch is or are used or bet from the credit and the credit is subjected to deduction accordingly and the control returns to the initial state A.
When coins are inserted from the lump-insertion tray 71, the coin sensor 9 is turned on (S6) and the automatic coin-sucking is carried out. Unless any of the 'following events occurs in the midst of the sucking operation, such as the number of coins in the credit becoming 50 any of P OPER Arl ol-'I pd I0,11 -26the coin-insertion or bet switches 81, 82, 83 are turned on or the coin sensor 6 continues in a non-detecting state for 3 seconds with no coins being actually sent from the rotary disc the rotary disc 3 continues rotating (SI0) and the solenoid type drive means 401 at the coinselection part 4 is turned on to perform the coindiscrimination (S11) In this case, false coins are rejected to the coin tray 8G while true coins are detected by the true-coin sensor 5 and the credit is subjected to addition accordingly (S12) When the number of coins in the credit becomes 50 (S7) or the coin sensor 6 is in non-detecting state for 3 seconds during the automatic sucking operation, the rotary disc 3 is stopped (S13) and the control returns to the initial state A. Where any of the coin-bet switches 81, 82, 83 is turned on (S8) during the automatic sucking, the rotary disc 3 is stopped (S14) followed by the step S5 in which coins are used or bet from the credit and the credit is given deduction, and the control returns to the initial state A.
As seen in Fig. 22, when the manual storing switch is turned on (S15) rather than the automatic coin-insertion based on the coin sensor 9, the manually-operated coinsucking operation is carried out. Unless any of the P OPERA, ol 1 jp, 11, 0l1 -27following events occurs in the midst of the sucking operation, such as the number of coins in the credit becoming 50 (S16); the manual storing switch 70 being turned off (S17) or the game start switch 80 being turned on (S18), the rotary disc 3 continues rotating (S19) and the solenoid type drive means 401 at the coin-selection part 4 is turned on to perform the coin-discrimination (S20) In this case false coins are rejected to the coin tray 8G while true coins are detected by the true-coin sensor 5 and the credit is subjected to addition accordingly (S12) When the manual storing switch 70 is let go to be turned off (S17) during the manually-operated sucking, the rotary disc 3 is stopped (S22) and the control returns to the initial state A. When the number of the coins in the credit becomes 50 (S16) or the game start switch 80 is turned on (S18) during the manually-operated sucking operation, the rotary disc 3 is stopped (S23) and the control skips over the step S24 to the control state D) to deem the game start switch 80 to be "ON".
When the game start switch 80 is turned on (S24) and one, two or three coins are normally bet (S25), rotation of the reels 8L, 8M, 8R (S26), stoppage of the reels by the stop buttons 8e, 8m, 8r (S27), determination of winnings (S28) and coin-payout according to winnings (S29) are P OPER Arl 761~5-9 spcdw-27/i lI)I -28performed, followed by ending of the game. For the coinpayout, the number of coins corresponding to specific winning features are added to the credit or actually paid out from the coin payout device 72 to the tray 8G.
The coin-selection part 4 is formed, as shown in Figs.
11 and 12, in the forcible-transfer portion 20 of the passage in which the transfer force of the rotary disc 3 acts on sent coins, and false coins IM are removed from the passage as shown in Fig. 17 according to driving of the rotary disc 3 to thereby allow only true coins TM to be taken out as shown in Fig. 13. Accordingly, discriminating coins as well as lining up coins can be performed at the same point where the rotary disc 3 is provided. Difference in height between the inlet of the lump-insertion of coins and the outlet of coins after discriminated can be made smaller. Hence, restriction in spaces inside various machines for mounting the coin-sending device can be mitigated, and enlargement and complexity of the structures of the machines can be prevented.
As shown in Fig. 16, the true-coin sensor 5 does not detect false coins that have been removed by the coinselection part 4 but detects only true coins TM. Thus, counting true or standardized coins and recognition of their passing can be precisely carried out without errors.
P. OPERAIrlI '175-')S lp.do-271 11 -29- As shown in Figs. 11 and 12, coins M are travel smoothly via the coin-transfer means 30 along the passage 2 including the arcuate portion 200 of the passage following rotation of the rotary disc 3. Coins M guided smoothly to the coin-selection part 4, thereby enabling the coinselection to be performed efficiently.
As seen in Fig. 6, the passage 2 includes a recess 201 having a necessary depth for coin M in the direction of its thickness, and enabling the whole device to be made flat or smaller in height. The passage is built by layering the cover member on the base member, thereby making the structure simple.
As shown in Fig. 13, true coins TM which are each supported at boti lateral sides by a pair of coin supporters 41, 42 at the coin-selection part 4 are transferred to and received by the passage 2. As seen in Fig. 17, false coins IM smaller in diameter than true coins are not supported by the supporters 41, 42 to be removed through the removal opening 40. Thus, coin-selection can be performed simply and efficiently.
One coin-supporter 42 allows the width of opening of the removal opening 40 to be equal to or larger than diameter of true coins TM as shown in Fig. 19. Hence, true coins TM can be also retrieved through the removal opening P OPERAAI%6175--)X U11.doc-2,: I As seen in Fig. 7, the swing member 403 swings around the fulcrum 402 by the drive means 401 to shift the coinsupporter 42 comprising the movable member 400. Thus, the usual selection state shown in Figs; 12 and 13 and the state of retrieval of all coins shown in Figs. 18 to 19 can be readily determined.
As seen in Fig. 13, true coins TM which slant downwards when about to be received by the passage 2 after passing the coin-selection part 4 can be corrected in their orientation by the coin-scoop means 43. Hence, true coins can be smoothly guided and transferred to the passage 2 without striking the end part of the removal opening As seen in Fig. 4, all coins before introduced into the coin-selection part 4 can be detected by the coin sensor 6.
Thus, when no further coins can be detected after a predetermined time, the machine recognises that no coins are being sent from the rotary disc 3 and the rotary disc 3 is idling. Furthermore, all of the coins, no matter whether they are true or. false ones, can be counted up at the same place.
As shown in Fig. 3, any excess of stored coins will overflow in a predetermined direction along the overflow guide 10. Hence, any excess coins over the capacity of the p OPER"Ar 7(175-9X do. I.ll -31reservoir can be disposed or storedby the machine.
As seen in Fig. 3, the whole device is set slantwise with respect to the horizontal plane HP with the outlet 202 of the passage 2 facing downwards, so that true coins can be taken out efficiently.
As seen in Fig. i, coins inserted in a lump from the lump-insertion tray 71 are first stocked in the reservoir 1 and then sequentially discriminated one by one, so that true coins are fed from the outlet 202 of the passage 2 to the coin payout device 72. False coins removed by the coinselection part 4 go to the coin payout opening 73.
Accordingly, coins can be lined up and discriminated at the same place or point, whereby the height of the outlet for true coins after discriminated can be set to be sufficiently or substantially high in comparison with the coin-payout device 72, so that the lump-insertion tray 71 can be disposed in a proper position without being intentionally higher in comparison with the conventional one-by-one insertion type of coin slot. Hence, players can easily insert coins in a lump at a convenient location on the machine. Coins can also be prevented from jamming in the coin passage in the game machine.
As shown in Figs. 1 and 2, coins inserted into the machine 8 and stocked in the reservoir 1 can be P OPER Il 9 ipe d If01 32 seen from the outside and so a player can readily watch or observe of the storing of coins, or whether the coins are stored in large or small numbers.
As shown in Fig. i, coins, when placed into the lumpinsertion tray 71, are detected by the coin sensor 9.
According to the detection by the coin sensor 9, the rotary disc 3 is rotated automatically as seen in the steps S6 and in Fig. 21, so that coins are taken in automatically and lined up and discriminated.
When any of coin-insertion switches 81, 82 and 83 are operated, as shown in Fig. 2, during the automatic coinsucking operation, the rotation of rotary disc 3 is stopped as seen in the steps S8 and S14 in Fig. 21. Hence, players can concentrate on the game, and this prevents confusion in the change in the numerical indication caused by deduction from the credit corresponding to the number of coins to be used for the game about to be played and addition to the credit corresponding to the automatic coin-sucking operation.
When there are no coins to be sent by the rotary disc 3, the coin-sensor 6 is brought into the non-detecting state over a predetermined time interval to thereby automatically stop the rotary disc 3 as shown in the steps S9 and S13 in Fig. 21. Hence, the automatic sucking operation is fully P OPER AI 1I pc- dr I.1 0 -33 ended, thereby enabling energy. saving and less noise generation from the machine.
When the manual-storing switch 70 is turned on as shown in Fig. 2, the rotary disc 3 rotates as shown in the steps S15 and S19 in Fig. 22 to enable the manually-activated coin-sucking operation. When the switch 70 is turned off, the rotary disc 3 is stopped as shown in the steps S17 and S22 in Fig. 22 to end manually-activated coin-sucking.
Accordingly, players can arrange and use the coin-storage at their discretion for playing the game.
When the game start switch 80 is operated during the manually-activated coin-sucking operation as shown in Fig.
2, the rotation of rotary disc 3 is stopped as seen in the steps S18 and S23 in Fig. 22. Hence, players can concentrate on the game and clearly determine the coins obtained by winning the game.
As seen in the steps S7 and S13 in Fig. 21 and the steps S16 and S23 in Fig. 22, when the number of coins credited in the game machine 8 becomes a predetermined number, the rotary disc 3 is stopped to end the coin-sucking operation. This prevents coins being taken into the machine 8 in large numbers at a single time, thereby limiting the playing time on the game and so reduce the amount of money spent at a single time.
P OPER Af T I-93 AU 0 1 -34- As seen in the steps Si and S3 in Fig. 21, when the settlement switch 84 is operated, all the stored coins are forcibly discharged to the coin-payout opening 73 through the removal opening at the coin-selection part 4. Thus, players can stop the game at their discretion without losing any coins.
An example of application of the coin-sending device to the game machine 8 has been referred to in the above explanation. The coin-sending device is applicable also to various vending machines, and automatic money-transfer machines and coin-discrimination machines usable in banks, or the like. Moreover, several kinds of coins having different sizes, for example, those in Japanese denominations of 500, 100, 50 and 10 yen, when mixed, can be sorted out into the respective kinds by employing the present invention, in addition to determination or discrimination of true and false coins of the same kind.
In this case, sizes of the holes 34 at the rotary disc 3 and the removal opening 40 at the selection part 4 may be adapted to correspond to standard sizes of those coins to provide a plurality of the components each having the holes 34 and the removal opening 40 in a specific size. The components are aligned vertically, so that coins in a larger diameter are picked up at the component disposed at the top P:OPERW\7617-98 di, pgp.do.-23/OAl02 stage and other coins may be sequentially received through the removal openings into the reservoirs on the components placed at the lower stages.
Throughout this specification and the claims which follow, unless the context requires otherwise, the word "comprise", and variations such as "comprises" and "comprising", will be understood to imply the inclusion of a stated integer or step or group of integers or steps but not the exclusion of any other integer or step or group of integers or steps.
The reference to any prior art in this specification is not, and should not be taken as, an acknowledgment or any form of suggestion that that prior art forms part of the common general knowledge in Australia.
