The overflow process shown in FIG. 8 and the storage full warning process shown in FIG. 19 are executed as follows.
It is controlled by the program in M72.

[Change Payment Processing] When the CPU 70 receives change data corresponding to the amount of change paid in coins from the POS terminal via the communication interface 74, the CPU 70 executes S
At T (step) 1, the number of coins to be paid out is determined, which is the minimum number of coins when paying this change amount.

Specifically, first, it is determined whether or not the change data is 500 yen or more, which is the maximum unit of coins, and only when the change data is 500 yen or more, the payout number of 500 yen coins is set to "1", and the change data is set. The amount of money obtained by subtracting 500 yen is used as new change data.

Next, it is judged whether or not the change data is 100 yen or more. Only when the change data is 100 yen or more, the payout number of 100 yen coins is set to "1" and the amount obtained by subtracting 100 yen from the change data is newly set. Change data. Then, it is determined again whether the change data is 100 yen or more. Here, when the amount is 100 yen or more, the number of 100 yen coins to be dispensed is set to "2" and the amount obtained by subtracting 100 yen from the change data is set as new change data. In this way, the above processing is repeated until the change data is less than 100 yen.

Next, it is determined whether or not the change data is 50 yen or more. Only when the change data is 50 yen or more, the payout number of 50 yen coins is set to "1", and the amount obtained by subtracting 50 yen from the change data is newly added. Change data.

Next, it is determined whether or not the change data is 10 yen or more. Only when the change data is 10 yen or more, the payout number of 10 yen coins is set to "1", and the amount obtained by subtracting 10 yen from the change data is newly set. Change data. Then, it is determined again whether the change data is 10 yen or more. Here, if the amount is 10 yen or more, the number of coins to be paid out of 10 yen coins is set to "2", and the amount obtained by further subtracting 10 yen from the change data is set as new change data. In this way, the above processing is repeated until the change data is less than 10 yen.

Next, it is determined whether or not the change data is 5 yen or more. Only when the change data is 5 yen or more, the payout number of 5 yen coins is set to "1", and the amount obtained by subtracting 5 yen from the change data is newly added. Change data.

Finally, the remaining change data is determined to be the payout number of 1-yen coins, and the payout amount determination process for this denomination is terminated.

The CPU 70 sets the thus determined payout number for each type of money in the payout number area of the type table 73a. In addition, the throwing-out number counter of the denomination table 73a is initialized to "0" for all denominations.

Furthermore, when the payout flag in the flag storage area 73b is set to the set state indicating that the change is being paid out, the power supply to the payout motor 64 is turned on via the motor drive circuit 80. In addition, the shutter member driving solenoid 28 of the coin storage unit 19 in which coins to be dispensed whose number of coins to be dispensed is 1 or more is selected, and the selected shutter member driving solenoid 2 via the solenoid drive circuit 83.
Turn on the power to 8. The distribution mechanism 56 is de-energized, and the coins discharged from the coin storage unit 19 are guided to the guide body 53 side.

As a result, the coin payout roller 23 and the cam portion 24 are rotationally driven, and the corresponding shutter member 26 is opened, so that the rotational frictional force of the coin payout roller 23 causes one corresponding coin from the coin storage portion 19. The coins are discharged one by one and discharged to the coin payout outlet 54 through the guide body 53.

At this time, the CPU 70 monitors the sensor signal input circuit 87 in step ST2 to detect each coin dispensing sensor 6
The input of the payout detection signal from 3 is awaited. Then, every time a payout detection signal is input from any one sensor 63, in ST3, the payout number counter of the denomination corresponding to the sensor 63 is incremented by “+1” and the stored number counter of the same denomination is increased. Is decreased by "-1".

Here, in ST4, the value of the payout number counter of this denomination is compared with the value of the payout number area, and if they match, the coin storing section 19 in which coins of the same denomination are stored in ST5. 28 for driving the shutter member
Turn off the power to the. As a result, the corresponding shutter member 26 is closed and the coin discharge is stopped.

In this way, the above-mentioned processes of ST2 to ST5 are repeated until the value of the number-of-dispensed coins counter coincides with the value of the coin-dispensed coin area for all denominations of coins to be paid out. After that, the power supply to the payout motor 64 is turned off, and the payout flag is reset to the non-payment state. Thereby, the coin dispensing roller 2
3 stops.

Further, the power supply to the drawer opening / closing drive mechanism 59 is turned on via the drawer opening / closing drive circuit 81, and the change payout process is completed. This opens the drawer 58.

[Coin storing process] The CPU 70 checks the payout flag at ST11 each time the interrupt signal X generated at, for example, 100 ms intervals is input from the timer controller 71. When the payout flag is reset, the change coin is not paid out, so ST12
As a result, it is checked whether or not the coin insertion sensor 60 detects the insertion of coins by the input signal to the sensor signal input circuit 84.

If coin insertion is detected,
The timer counter 73d is initialized to "0" and
In ST13, the in-storage flag in the flag storage area 73c is checked. If the storing flag is reset, it means that the inserted coin is not stored, so ST
The storing flag is set to 14 to indicate that coins are being stored, and the motor drive circuits 78, 79, 80
If the energization of the input motor 65, the conveyance motor 50, and the payout motor 64 is sequentially turned on via, the process ends.

As a result, the conveyor belt 38 and the separation roller 39 are driven, and the conveyor belt 45 is driven. Further, the coin payout roller 23 and the cam portion 24 are also driven to rotate, so that the coins inserted into the coin slot 11 are stored in the coin storage portion 19 corresponding to the denomination.

When the storing flag is set in ST13, the charging motor 65, the conveyance motor 50, and the payout motor 64 are already energized, and the inserted coins are being stored. The process ends without performing the process.

If coin insertion is not detected in ST12, the in-storage flag is checked in ST15. If the storing flag is reset, it means that no coin has been inserted and the coin is not being stored, so this processing ends.

When the storing flag is set in ST15, the coins are being stored, so the timer counter 73d is incremented by "+1". Next, ST16
As a value of the timer counter 73d is set to a preset value (a coin storage unit 19 is inserted after one coin is inserted).
The value of the timer counter, which corresponds to a time sufficiently longer than the time required to be transported and stored up to, is determined.

Here, when the value of the timer counter 73d has not reached the specified value, it is determined at ST18 whether or not the coin is selected by the coin selection sensor 62 by the input signal to the sensor signal input circuit 86. When it is determined that coins are selected, the stored number counter of the denomination table 73a corresponding to the denomination of coins selected by the coin selection sensor 62 is incremented by "+1" at ST19. If the timer counter 73d is initialized to "0" at ST20, this process is terminated.

On the other hand, when it is determined in ST18 that the coins have not been selected, this process is terminated without performing the processes of ST19 and ST20.

On the other hand, at ST17, the timer counter 73d
If the value of exceeds the specified value, all the inserted coins are stored in the coin storage unit 19, and it can be determined that there are no coins in the coin insertion slot 11 and on the guide plate 40, so the storage flag is set Along with the reset state indicating that the storage
The energization of the charging motor 65, the conveyance motor 50, and the payout motor 64 are all turned off, and this process ends.

If the paying-out flag is set in ST11, change coins are being paid out, so ST2
The stored flag is checked as 1. Here, if the storing flag is set, the change dispensing process is started during storing of the input coin and the dispensing flag is set, so that the change dispensing process is prioritized, ST22 is storing. At the same time as resetting the flag, the energization of the closing motor 65 and the carry motor 50 is turned off, and this processing is ended.

When the storage flag is reset in ST21, the processing of ST22 is not performed and
This process ends.

[Overflow processing] The CPU 70 checks the payout flag and the storage flag each time the timer controller 71 inputs an interrupt signal Y generated at one-minute intervals, for example. Then, if any of the flags is set, it means that the change coins are being paid out or the input coins are being stored, so this processing is ended.

On the other hand, when both flags are reset, the stored number counter of each denomination in the denomination table 73a is compared with the upper limit number preset in the upper limit number setting area. Determine if there is an overflow. Then, if there is no denomination of the stored number counter exceeding the upper limit number, it is determined that there is no overflow, and this process ends.

On the other hand, if the number of stored coins counter for at least one denomination exceeds the upper limit, it is determined that there is an overflow. Then, the power distribution to the distribution mechanism 56 is turned on via the distribution mechanism drive circuit 82. Further, the power supply to the payout motor 64 is turned on via the motor drive circuit 80. Further, the shutter member driving solenoid 28 of the coin storing portion 19 in which the coins to be ejected of the denomination whose storage number counter exceeds the upper limit number is stored is selected, and the selected shutter member driving is performed via the solenoid drive circuit 83. The energization of the solenoid 28 is turned on.

As a result, the sorting mechanism 56 is provided in the coin storage unit 1.
The coin discharged from 9 is moved to a position for guiding the coin to the overflow container 55 side. Further, as the coin dispensing roller 23 rotates, the corresponding shutter member 26 opens,
The corresponding coins are ejected from the coin storage unit 19 one by one,
It is stored in the overflow container 55.

Next, in ST31, the sensor signal input circuit 87 is monitored, and the input of the payout detection signal from each coin payout sensor 63 is awaited. Then, each time a payout detection signal is input from any one of the sensors 63, the stored coin number counter of the denomination corresponding to the sensor 63 is decremented by "-1" at ST32.

Here, in ST33, the reduced storage number counter is compared with the upper limit number, and if the stored number becomes less than or equal to the upper limit number, in ST34, a coin storing unit storing coins of this denomination. The power supply to the shutter member driving solenoid 28 of 19 is turned off. As a result, the corresponding shutter member 26 is closed and the coin discharge is stopped.

In this way, the above-mentioned processes of ST31 to ST34 are repeated until the value of the stored number counter becomes less than or equal to the upper limit number for all denominations of coins to be discharged due to overflow. Then, if the power supply to the payout motor 64 is turned off and the power supply to the distribution mechanism 56 is turned off, this process ends.

As a result, the rotation of the coin payout roller 23 is stopped, and the sorting mechanism 56 returns to the position where the discharged coins from the coin storage portion 19 are guided to the guide body 53 side.

[Store Full Warning Processing] The CPU 70 checks the input signal to the sensor signal input circuit 85. When it is confirmed that the full coin detection signal is received from the stored coin sensor 61, any one of the coin rows formed by the coins stored in the coin storing unit 19 of the denomination by the stored coin sensor 61 is detected. Since the length is equal to or longer than the predetermined length of coins formed by the upper limit number of coins at which the overflow process is started and the storage full state is detected, the display control circuit 77 is controlled to display the display unit 1.
Display the error code indicating the storage full error in 3 and
Warn the user.

Next, the storage flag is checked. And
If it is set, it is storing coins, so S
At T41, the in-storage flag is reset, the energization of the closing motor 65, the conveyance motor 50, and the payout motor 64 are all turned off, and the storage full warning process is ended. Thereby, the storing operation of the inserted coin is stopped.

On the other hand, when the in-storage flag is reset, the processing of ST41 is not performed and the storage full warning processing is ended.

As described above, in the embodiment of the present invention, the coins inserted from the coin slot 11 are conveyed by the coin conveying mechanism 37 to the position above the coin payout rollers 23. Then, the coin conveyed to a position above the coin payout roller 23 is guided by the guide member 52 between the coin payout roller 23 and the coin abutting against the coin payout roller 23. Then, the coin guided between the coin dispensing roller 23 and the coin abutting the roller 23 enters the coin storage space S formed by the cam portion 24, and the coin is stored in the coin storage portion 19 as a coin storage means. It is stored in a row in the horizontal direction with the surfaces stacked on top of each other.

Therefore, in one embodiment of the present invention, since it is not necessary to stack coins in the vertical direction and store them, the device can be made thin without being affected by the storage capacity of the coins. Further, since the inserted coins are stored in a row in the horizontal direction with the surfaces of the coins stacked on each other in the coin storage unit as the coin storage means, there is no occurrence of defective coin delivery as in the conventional example described above. .

Further, in one embodiment of the present invention, the coins stored in the coin storage portion 19 are dispensed one by one from the coin storage portion 19 by the rotation of the coin storage / delivery roller 23, so that the coin storage portion 19 is different from the one in the hopper type. The payout speed of coins can be increased.

Further, in one embodiment of the present invention, one end of the coil spring 34 as a biasing member for biasing the pressing member 33 to the front side of the coin storing portion 19 is provided below the front end portion of the coin storing portion 19. Since it is locked to the pin 36 provided below the rear end of the coin storage portion 19 via 35,
The coin storage capacity can be increased without increasing the length of the coin storage section 19 as compared with the case where a coil spring is incorporated in the coin storage section 19 and the coin is pressed against the coin storage / delivery roller 23.

Although the coin dispensing roller 23 and the cam portion 24 are made of an elastic material such as urethane rubber in the above-described embodiment, the portion where the cam portion 24 is provided is made of resin such as polyacetal as shown in FIG. It may be formed of a material.
That is, the roller body 23a having the cam portion 24 is formed of a resin material such as polyacetal, and the roller surface forming member 23b made of an elastic material such as urethane rubber is provided on the peripheral surface portion of the roller body 23a excluding the cam portion 24 to dispense coins. Roller 23
May be formed. By doing so, the friction coefficient of the cam portion 24 becomes small, so that the load on the drive mechanism for driving the coin dispensing roller 23 can be made small.
