It has a relationship larger than the diameter D of the coin C stored in the portion 50.

The width of the groove 72 is larger than the diameter D of the coin C stored in the storage 50.

Next, FIG. 12 shows a seventh embodiment.

The coin feeding device 26 shown in the seventh embodiment has a different layout from the coin feeding device 26 shown in the first embodiment, but the basic configuration is the same, and the description thereof will be omitted by using the same reference numerals. To do.

On each of the conveyor belts 67, a storage unit 50 of a denomination for storing the coin C is provided upstream of the reverse rotation roller 68 in the transport direction F, and coins delivered as change as a change downstream of the reverse rotation roller 68 in the transport direction F. A withdrawal holding unit 90 for temporarily holding C in advance is provided. Coins C of, for example, 1 yen, 10 yen, 100 yen, 500 yen, 5 yen, and 50 yen are stored in the storage units 50 (50a, 50b, 50c, 50d, 50e, 50f) for each denomination. As described above, by temporarily holding the coin C to be paid out as change in the withdrawal holding unit 90 for each type of money, it is possible to promptly pay out the change amount necessary for paying out the change amount.

The reference value temporarily held in advance in the withdrawal holding section 90 for each type of money is 5 yen, 50 yen for each 4 coins C of 1 yen, 10 yen and 100 yen, since the maximum change is 999 yen. And each coin C of 500 yen becomes one each.

Immediately after the reverse rotation roller 68, the first stopper mechanism and the first coin detecting unit are arranged on the inlet side of the withdrawal holding unit 90, and the second stopper mechanism and the second coin mechanism are provided on the outlet side of the withdrawal holding unit 90. The coin detecting part of is arranged. Then, at the time of temporary holding, the conveyor belt 67 and the reverse rotation roller 68 rotate, and the first stopper mechanism and the first coin detecting unit cause the coins of the reference value to be temporarily held in advance for each denomination to the withdrawal holding unit 90. When the change is received and held, the conveyor belt 67 and the reverse rotation roller 68 rotate at the time of paying out the change, and the second stopper mechanism and the second coin detecting unit only the coin C of the denomination required for the change is held in the payout holding unit. Get out of 90.

In such a coin feeding device 26, generally, if there is even one denomination in which the number of the coins C stored in the storage part 50 has not reached the reference value, the processing of the money handling machine 12 is stopped, You will have to replenish coin C.

In the present embodiment, even if there is a denomination in which the number of coins C stored in the storage unit 50 does not reach the reference value, the coins C are stored in the storage unit 50 without stopping the processing. The coin C is temporarily held in advance in the withdrawal holding section 90 within the range. For example, the reference value for 1-yen coins is 4, but even if only 3 coins are stored in the storage unit 50 (50a), three 1-yen coins are temporarily stored in the withdrawal storage unit 90 in advance, Further, even if there are no 50-yen coins in the storage unit 50 (50f), coins of other denominations are temporarily held in advance.

Then, at the time of paying out the change, for example, if the required number of 1-yen coins is 3 or less, three 1-yen coins are paid out from the withdrawal holding section 90, and if they are 4, currency processing It informs that the processing of the machine 12 is stopped and 1 yen coin is replenished. Further, for example, if the required number of 50-yen coins is 0 at the time of change payment, it is necessary to pay out the required number of coins from the withdrawal holding unit 90 of another denomination, and also the 50-yen coins. For example, the processing of the money handling machine 12 is stopped, and it is instructed to replenish the 50-yen coin. Even if the coins C in the storage section 50 are reduced or lost, the coins may be replenished by the deposit process.

Thus, even if there is a denomination in which the number of coins C stored in the storage unit 50 does not reach the reference value, the coins stored in the storage unit 50 do not stop the processing of the money handling machine 12. Since the money is temporarily held in advance in the withdrawal holding unit 90 within the range of C, it is possible to reduce the chance of stopping the money handling machine 12.

Next, FIG. 13 shows an eighth embodiment.

A transmission mechanism 93 that transmits a driving force to various mechanisms such as a belt in the coin feeding device 26 or in the money handling machine 12 is shown.

As shown in FIGS. 13(a) and 13(b), the transmission mechanism 93 includes a pair of gears 94 meshing with each other, a pair of shafts 95 fixing the respective gears 94, and the shafts 95 capable of rotating. And a pair of bearing units 96 that support the same. The shaft tube dimensions of the pair of shafts 95 are defined in a state where the pair of bearing units 96 are in contact with each other.

In the transmission mechanism 93 using such a gear 94, the gear 94 vibrates due to the backlash of the gear 94, and noise is likely to occur.

In the present embodiment, as shown in FIG. 13A, the bearing unit 96 is brought into contact with the other bearing unit 96 via an elastic member 97 provided around the bearing unit 96. Alternatively, as shown in FIG. 13B, the other bearing unit 96 is brought into contact with the other bearing unit 96 via an elastic member 97 provided around the both bearing units 96. The elastic member 97 is, for example, rubber or the like.

In this way, by interposing the elastic member 97 between the pair of bearing units 96, the vibration generated by the meshing of the gears 94 can be attenuated and the generation of noise can be reduced.

Further, in FIG. 13C, an elastic member 97 is provided around the bearing unit 96 of only one shaft 95, and this elastic member 97 is brought into contact with the other shaft 95. In this case, when the bearing unit 96 is fixedly used as a bearing member, only one shaft 95 is rotatably supported by the bearing unit 96, the other shaft 95 does not rotate, and the other shaft 95 does not rotate. The gear 94 of the can be rotated. On the other hand, another bearing (not shown) is provided on one shaft 95 rotatably supported by the bearing unit 96, and the bearing unit 96 is rotatably arranged. In the case of such a configuration, the rotation of the one shaft 95 can be transmitted to the other shaft 95 by the pair of gears 94 meshed with each other to rotate. Also in this case, the elastic member 97 can attenuate the vibration generated by the meshing of the gears 94 and reduce the generation of noise.
