Description
Detailed Description of the Invention
1. Field of the Invention
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.
2. Prior Art
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, so that players place coins into the slot one by one by their hands. Inserting coins one by one is troublesome for the players. But coins inserted are received by the machine one by one sequentially and sent to the further stages. Thus, a coin-selection (or discrimination) device C1 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. The lump-insertion tray w exemplified in FIG. 23 showing the aforesaid Japanese publication is used jointly together with the coin slot J that 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 provided below the wide tray W in the direction of the pull of gravity, to a coin-selection (or discrimination) device C2 disposed under the coin-sending device F in the direction of the pull of gravity and above the coin-payout 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 coin-sensor on a coin-passage extended from the coin-sending device F.
In the feature having the lump-insertion tray W, the coin-sending device F is to be additionally provided with respect to the coin-selection device C2. It results in such problem that the lump-insertion tray W is to be formed as higher in position than the coin slot J, i.e., 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 is to be fully ensured so as to enable coins to sequentially flow smoothly in the machine from the upper part to the lower part. Hence, it is not easy but troublesome for players sitting on the seats in front of the game machines to place coins in the lump-insertion tray W, and this countermeasure for mitigating the trouble of players inserting coins one by one becomes useless or futile.
It is possible to provide the lump-insertion tray W at the same height as the coin slot J that is for inserting coins one by one, as shown in Unexamined Japanese Patent Application No. Hei 2-57284 (1990). In this case, a drop from the lump-insertion tray W to the coin-payout device H cannot be sufficiently obtained , leading to such separate problems that the coin-passage is stopped up or jammed by coins and a coin-reservoir bucket in the coin-payout device H is to be reduced in size.
Moreover, since the coin-selection device C2 and the coin-sending device F are provided separately from each other, there are required a larger number of parts to that extent and a higher cost to produce, and an additional passage connecting the coin-sending device F and the coin-selection device C2, thereby causing the whole machine to be complex in structure and larger in size, leading to a problem of loss of space.

The forcible-discharge mechanism may have the structures disclosed, for example, in claims 4 to 13.
Next, functional effects of those inventions will be detailed.
In the invention set forth in claim 1, the coin-selection part 4 is formed, as shown in FIGS. 11 and 12, in the forcible-transfer passage 20 in which the transfer force of the rotary disc 3 acts on coins sent, and false coins IM are removed from the passage as clarified 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.
In the invention set forth in claim 2, as shown in FIG. 16, the true-coin sensor 5 does not detect false coins that have been removed by the coin-selection 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.
In the invention set forth in claim 1, as shown in FIGS. 11 and 12, coins M are smoothly travelled by the coin-transfer means 30 along the second-side passage 2 including the arcuate passage 200 following rotation of the rotary disc 3 and are smoothly guided to the coin-selection part 4, thereby enabling the coin-selection to be excellently performed.
In the invention set forth in claim 3, as seen in FIG. 6, the second-side 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. And the passage is built by layering the cover member on the base member, thereby making simple the structure.
In the invention set forth in claim 4, as shown in FIG. 13, true coins TM which are each supported at both lateral sides by a pair of coin supporters 41, 42 at the coin-selection part 4 are transfered to and received by the second-side 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 excellently.
In the invention set forth in claim 12, 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 retreived through the removal opening 40.
In the invention set forth in claim 13, as seen in FIG. 7, the swing member 403 swings around the fulcrum 402 by the drive means 401 to shift the coin-supporter 42 comprising the movable member 400. And the usual selection state shown in FIGS. 12 and 13 and the state of retrieval of all coins shown in FIGS. 18 and 19 can be readily realized.
In the invention set forth in claim 5, as seen in FIG. 13, true coins TM which slant downwards when about to be received by the second-side passage 2 after passing the coin-selection part 4 can be corrected in posture by the coin-scoop means 43. Hence, true coins can be smoothly guided and transferred to the second-side passage 2 without striking the end part of the removal opening 40.
In the invention set forth in claim 6, 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 the state having no such detection continues, there can be known or recognized the facts that no coins are sent from the rotary disc 3 and the rotary disc 3 is idling. Furthermore, all of coins no matter whether they are true or false ones can be counted up at the same place.
In the invention set forth in claim 7, as shown in FIG. 3, excess of stored coins overflows in a predetermined direction along the overflow guide 10. Hence, the excess of coins over the capacity of the reservoir can be disposed well.
In the invention set forth in claim 8, as seen in FIG. 3, the whole device is set slantwise with respect to the horizontal plane HP with the outlet 202 of the second-side passage 2 facing downwards, so that true coins can be taken out excellently.
In the invention set forth in claim 9, as seen in FIG. 1, coins inserted in a lump from the lump-insertion tray 71 are first stocked in the first-side reservoir 1 and then sequentially discriminated one by one, so that true coins are fed from the outlet 202 of the second-side passage 2 to the coin payout device 72. False coins removed by the coin-selection 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 proper or favourable position. And coins can be prevented from jamming in the coin passage in the game machine.
In the invention set forth in claim 10, as shown in FIGS. 1 and 2, coins inserted into the machine 8 and stocked in the first-side reservoir 1 can be seen from the outside to be readily watched or observed of their being stored or not, or of stored in a large or small number.
In the invention set forth in claim 14, as shown in FIG. 1, coins when placed into the lump-insertion 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 S10 in FIG. 21, so that coins are taken in automatically and lined up and discriminated.
In the invention set forth in claim 15, when any of coin-insertion switches 81, 82 and 83 is operated, as shown in FIG. 2, during the automatic coin-sucking operation, the rotary disc 3 in rotation is stopped as seen in the steps S8 and S14 in FIG. 21. Hence, players can concentrate on the game, and there is prevented an entangled change in the numerical indication caused by or between 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.
In the invention set forth in claim 16, when there is 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 cause the rotary disc 3 to be automatically stopped as shown in the steps S9 and S13 in FIG. 21. Hence, the automatic sucking operation is properly ended, thereby enabling energy saving and less noise generation.
In the invention set forth in claim 17, 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 the manually-activated coin-sucking. Accordingly, players can arrange and use the coin-storage in their discretion for playing the game.
In the invention set forth in claim 18, when the game start switch 80 is operated during the manually-activated coin-sucking operation as shown in FIG. 2, the rotary disc 3 in rotation is stopped as seen in the steps S18 and S23 in FIG. 22. Hence, players can concentrate on the game and clearly comprehend coins obtained by winning the game.
In the invention set forth in claim 19 or 20, 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. Thus, it can be prevented that coins in a quite large number are taken into the machine 8 at a time, thereby enabling playing the game to be wholesome.
In the invention set forth in claim 11, as seen in the steps S1 and S3 in FIG. 21, when the settlement switch 84 is operated, all of 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 freely in their discretion without having loss of coins.

A coin-sensor 9 for detecting coins inserted is provided inwardly of the lump-insertion tray 71. The arrows in FIG. 1 show the flow of coins.
As seen in FIG. 2, three mechanical reels 8L, 8M and 8R on the outer peripheries of which figures, such as "7", "cherries" and "oranges", are expressed 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 expressed on each reel is about twenty one (21).
Provided on the switches-mounting part 8D are coin-insertion switches (or coin-use switches) including a 1-bet switch 81 for the case using a single coin for a play, a 2-bet switch 82 for that using two coins and a max-bet switch 83 for that using three coins (at maximum). According to the number of coins used or inserted, judgement lines become valid, namely, a single coin when used or inserted causes the central judgement line L1 to become valid, two coins do so three judgement lines, i.e., the upper and lower lines L2 as well as the central one L1, and three coins do so five judgement lines including the slant lines L3. Indication lamps E1 to E3 are lit corresponding to specific judgement lines when become valid.
The game is started by moving up or down a game start switch 80 comprising a lever with a coin or coins having been bet by means of the bet-switches, whereby the three reels 8L, 8M, 8R start 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 alloted corresponding to winnings are determined according to a combination or combination(s) of the foregoing figures aligned on the valid judgement line(s). In case that the stop buttons are not operated, the reels are forcibly stopped about 40 seconds later from the start 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 first-side 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 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. 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 first-side 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 entirely formed by integral molding using syntheic resin such as polyacetal. The number of rotation of the rotary disc 3 is about 70 rpm.
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 second-side of the rotary disc 3. The coin-holes 34 have the same function as that provided by the feature that the opening slit of the conventional one-by-one insertion is set in size according to standardized coins.
As seen in FIG. 4, the base member 21 is provided thereon with the second-side passage 2 having an arcuate passage 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 passage 20 in which the transfer means 30 exerts a transfer-force on coins occupies almost the entire area of the second-side passage 2. The second-side 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-section 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 passage 20 in the second-side 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 coin-supporter 42, which forms a movable member 400 positioned inwardly, the coin-supporters 41 and 42 facing the coin-removal opening 40, and a coin-scoop means 43 disposed at the end of the coin-removal opening 40.
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 second-side 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 coin-selection part 4.
As seen in FIG. 7, the second coin supporter 42 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 retreival state (FIGS. 18 and 19) by a solenoid type of drive means 401 having a rod 404 which moves forwards and backwards following electricity 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 in the hole 34 to the bottom shifts slightly outwards from the hole to abut against the inner periphery of the coin guide 211 and be transferred by the coin-sending means 37. The coin when reaches the coin-releasing point 210, at which the coin guide 211 terminates, is released in the direction indicated by the solid line a by a centrifugal force to the second-side passage 2. Releasing 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 second-side 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 second-side 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 the 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 220 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 c). The anti-lock mechanism 220 cannot cause a false coin having non-standardized larger thickness to escape from the hole 34. But locking of the rotary disc 3 can be prevented by moving the pin 223 back a t maximum.
In case that a coin M is not sufficiently away from the coin-releasing point 210 and stops on the way as shown in FIG. 10, one end of the coin-transfer means 30 flicks the coin M circumferentially (indicated by the arrow d), causing the coin M to be sent outwards (indicated by the arrow e) without returning inwardly due to hindering by the coin-sending means 37 and pin 223 of the anti-lock mechanism 220.
FIG. 11 shows the coin M sent to the second-side 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-selectin part 4 as seen in FIG. 12.
As explained in FIG. 13, true coins TM in a standardized size are supported at both lateral ends opposing in the direction of diameter by the first and second coin supporters 41, 42 to be conveyed without falling in the coin removal opening 40. The upper surfaces of coins face closely a rear surface of the cover member 22, whereby there is no fear that the coins are turned over. True coins when 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 second-side passage 2.
As shown in FIG. 16, a true-coin sensor 5 is provided downstream of the coin-selection part 4. The sensor 5 comprises a detecting unit 50 using a transmission type photosensor, a linkage member 52 swingable to move in 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 pin 54 and a spring 56 for biasing the linkage member. True coins TM after subjected to the discriminating operation are brought into contact with the pin 54 to move the pin 54 backwards counterclockwise (indicated by the arrow f), whereby causing the linkage member 52 to be across the optical path 51 to detect a true coin and add one to the credit accordingly. The true coins TM after passing the sensor 5 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 device72.
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 off at the solenoid type drive means 401 provided at the coin-selection part 4, the rod 404 which has been retracted with the electricity being on is stretched to shift the second coin supporter 42 forming the movable member 400 (in the direction indicated by the arrow i) to make larger the width of the removal opening 40. When the rotary disc 3 rotates in this instance, all coins including true coins TM and false coins IM can be retrieved to 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 circuit.
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, coin-insertion switches (or coin-bet switches) 81, 82 and 83, settlement switch 84, a stop signal circuit 905 from the stop buttons Be, 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, i.e., 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 BR, a hopper drive circuit 909 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.
In case that the settlement switch 84 is turned on to request coin-payout (the step S1), 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 (S3), 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.
In case that the settlement switch is not turned on, when any of the coin-insertion (or bet) switches 81, 82, 83 is turned on (S4), 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 (S5), 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 such events occurs in the midst of the sucking operation that the number of coins in the credit becomes 50 (S7); any of the coin-insertion or bet switches 81, 82, 83 is turned on (SB); or the coin sensor 6 continues non-detecting state for 3 seconds with no coins being actually sent from the rotary disc (S9), the rotary disc 3 continues rotating (S10) and the solenoid type drive means 401 at the coin-selection part 4 is turned on to perform the coin-discrimination (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 (S9), during the automatic sucking operation, the rotary disc 3 is stopped (S13) and the control returns to the initial state A. In case that 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's return to the initial state A.
As seen in FIG. 22, when the manual storing switch 70 is turned on (S15) other than the automatic coin-insertion based on the coin sensor 9 turned on, the manually-operated coin-sucking is carried out. Unless any of such events occurs in the midst of the sucking operation that the number of coins in the credit becomes 50 (S16); the manual storing switch 70 is turned off (S17); or the game start switch 80 is 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 (S21).
When the manual storing switch 70 is let go of 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 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 jumps over the step S24 (i.e., to the control state D), the step S24 judging "ON" of the game start switch 80.
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 executed followed by ending the game. For the coin-payout, any 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.
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 stage and other coins may be sequentially received through the removal openings into the first-side reservoirs on the components placed at the lower stages.
