  Thereafter, in the coin storage 50a, the second screw type conveying member is rotated around the central axis of the second storage shaft portion 521 in a state where coins are stored in the foremost pitch constituted by the second storage blade portion 522. The coins stored between the foremost pitches are paid out one by one to the dispensing port 1 by being rotated once in one direction.

  In the coin processing device having the above-described configuration, in the deposit conveyance unit 10, the check unit 20, the temporary storage unit 30, the coin distribution unit 40, and the coin storage unit 50, the outer peripheral surface of the columnar shaft unit 111 and the like is provided. A conveying means for conveying coins is constituted by a screw-type conveying member 11 or the like in which a blade portion 112 or the like protruding outward in a radial direction is provided in a spiral shape. Since the screw-type transport member 11 and the like rotate around the central axis of the shaft portion 111 and the like, coins can be transported, resulting in a decrease in transport force due to dirt caused by the transported coins and the occurrence of tilted wheels. It is possible to suppress the occurrence of a conveyance failure. Therefore, it is possible to satisfactorily carry coins while suppressing a decrease in carrying force, the occurrence of inclined wheels, and the like.

  In the coin processing device, the coins to be deposited can be moved backward by rotating the first storage screw type transport member 51 around the central axis of the first storage shaft portion 511 in the other direction. A part of the coin can be brought into contact with the front surface of the rear portion 531 of the storage guide 53 so that the pile formed by the accumulation of the coin can be broken. As described above, the rear portion 531 of the storage guide 53 is curved in such a manner that the front central portion is concave, so that the coin abutting against the rear portion 531 can be reliably placed on its side, Can be prevented from staying in a posture in contact with the rear portion 531 and standing up. Therefore, the coin can be transported satisfactorily.

  In the coin processing device, the second conveying portion 58 of the storage guide 53 has the inclined surface 58a that extends in a mode of gradually approaching the first storage screw type conveying member 51 as it goes downward. It is possible to prevent the coins from standing up in a standing posture between the first storage screw type conveying member 51 and the side portions 532 of the storage guide 53. Therefore, the coin can be transported satisfactorily.

  In the coin processing device, since the first transport portion 57 of the storage guide 53 extends along the extending direction of the first storage shaft portion 511 and is provided at the lower portion of the storage reverse roller 56, the coin passage property is provided. As a result, coins can be transported well. Moreover, since the upper surface of the 1st conveyance part 57 is provided above the upper part of the 1st storage shaft part 511, and it is provided in the downward direction rather than the 1st storage blade part 512, the passage of a coin also by this Can be improved, and coins can be transported well.

  In the coin processing apparatus, since the first storage blade portion 512 of the first storage screw type transport member 51 has a trapezoidal longitudinal cross-sectional shape along the central axis of the first storage shaft portion 511, When the coin is pressed by the coin in the opposite direction, the coin can be moved obliquely upward on the side opposite to the transport direction, and the occurrence of lock due to coin clogging can be suppressed.

  In the coin processing apparatus, the rear end portion of the first storage screw-type transport member 51 is connected to the motor 55 via the storage spring 54 that biases forward, so that when the coin is transported due to coin clogging or the like. When the force toward the side opposite to the transport direction increases, the first storage screw type transport member 51 can be displaced rearward against the biasing force of the storage spring 54. Thereby, generation | occurrence | production of the lock resulting from a coin jam can be suppressed.

  In the coin processing device, since coins are stored one by one between the pitches constituted by the second storage blades 522 of the second storage screw type conveying member 52, preparations for withdrawal are made with the coins separated. doing. Thereby, when a withdrawal instruction is given, a predetermined number of coins can be paid out only by rotating the second storage screw type conveying member 52 a predetermined number of times in one direction. That is, since it is only necessary to pay out without separating and paying out stored coins according to a withdrawal instruction as in the prior art, it is possible to shorten the withdrawal time.

  In the coin processing device, the second storage screw-type transport member 52 rotates in one direction around the central axis of the second storage shaft portion 521 so that the coins stored between the foremost pitches face forward. Since each sheet is paid out, the number of coins paid out from the second storage screw type transport member 52 can be managed by controlling the number of rotations in one direction of the second storage screw type transport member 52.

  In the coin processing device, when the first storage screw-type transport member 51 rotates in one direction around the central axis of the first storage shaft portion 511, the linkage member 61 uses the rotational force of the second storage screw-type transport member. 52 to rotate the second storage screw type transport member 52 in the same direction as the first storage screw type transport member 51, while the first storage screw type transport member 51 rotates around the central axis of the first storage shaft portion 511. When rotating in the other direction, since the rotational force is restricted from being transmitted to the second storage screw type transport member 52, the coins stored one by one by the second storage screw type transport member 52 are rearward. It can be prevented from being conveyed toward

  The preferred embodiment of the present invention has been described above, but the present invention is not limited to this, and various modifications can be made.
