The pulley 102 is driven and rotated by the payout motor 110, whereby the payout belt 101 rotates. The payout belt 101 conveys coins from the rear part to the front part of the coin storage part 14.

  The coin payout unit 15 includes a reverse roller 105, a payout shutter 106, and a payout counting sensor 107 disposed at the exit of the coin storage unit 14. The reverse roller 105 rotates in the same direction as the payout belt 101 so that the payout belt 101 pays out coins C one by one. The payout shutter 106 is driven to open and close by a payout solenoid 108. The payout shutter 106 waits for the coin C in the closed state, while allowing the payout of the coins by the payout belt 101 in the open state. The payout counting sensor 107 detects coins paid out by the payout belt 101.

  Below the end position (front end) of the conveyor belt 32, a coin payout opening 109 opened upward is provided as shown in FIG. The coin payout exit 109 receives coins paid out by the payout belt 101. The coin payout exit 109 is arranged on the left side of the coin insertion slot 21.

  In addition, the deposit / withdrawal unit 2 has an operation panel 111 obliquely above and behind the coin payout exit 109. The operation panel 111 is provided with operation keys 112 and a display 113.

  FIG. 15 is a block diagram showing the electrical connection of the coin deposit / withdrawal apparatus. The coin deposit / withdrawal apparatus 1 is equipped with a CPU 121 as an information processing unit. The CPU 121 is connected to a ROM 122 in which fixed data such as programs are stored in advance and a RAM 123 in which various data are stored in a rewritable manner via a system bus 124. The CPU 121, the ROM 122, and the RAM 123 constitute a microcomputer.

  Further, the CPU 121 receives from the sensors S such as the input sensor 22, the count sensor 67, the payout count sensor 107, the box sensor 130, the material sensor 42, the diameter sensor 43, and the third identification sensor 44 via the system bus 124. An input port 125 for inputting a signal, an output port 126 for outputting a drive signal to the reject solenoid 52, the payout solenoid 108, etc., a communication interface 127 electrically connected to the POS terminal, an input motor 23, a transport motor 70, a payout A motor drive control unit 128 that individually controls the motors M such as the motor 110, and an operation control that is connected to the operation panel 111 and receives a key signal input from the operation key 112 and causes the display 113 to display data. Part 129 is connected. These units are driven and controlled by the CPU 121 according to a program.

  In such a configuration, if the coin C is inserted into the coin insertion slot 21, the coin C is detected by the insertion sensor 22. Upon receiving the detection signal from the making sensor 22, the CPU 121 drives the making motor 23 and the conveying motor 70 to rotate the making belt 24, the conveying belt 32, and the sorting belt 63. The coin C is transported to the coin transport surface 31 by the rotation of the insertion belt 24. Then, the coin C conveyed to the coin conveyance surface 31 is conveyed downstream in the coin conveyance direction by the rotation of the conveyance belt 32.

  Here, the conveyance belt 32 conveys the side surface of the coin C on the conveyance path whose width is gradually narrowed so as to press the conveyance guide member 34. Accordingly, the coin C is transported on the coin transport surface 31 by forming the same passage trajectory for each denomination.

  Further, as described above, the relationship between the angle α of the first inclined surface X and the angle β of the second inclined surface Y is such that the angle α> the angle β. The coins C exiting the insertion slot 21 can be widened.

  When the coin C is pressed against the transport guide member 34 and transported on the coin transport surface 31 in this manner, the coin C is referred to as one-sided transport. The reason why the coins C are transported in a single manner is as follows. When the diameter of the coin C is discriminated at the time of coin discrimination by the diameter sensor 43, it is necessary to position the coin by moving it to the guide guide and to discriminate the coin by the diameter sensor 43. For this reason, the coin C that has exited the coin insertion slot 21 needs to be positioned by being shifted to the transport guide member 34 at the time of coin discrimination.

  The coin C that is transferred to the conveyance guide member 34 by being moved on the coin conveyance surface 31 passes through the material sensor 42, the third identification sensor 44, and the diameter sensor 43.

  The CPU 121 executes coin discrimination based on outputs from the material sensor 42, the thickness / hole detection sensor (third discrimination sensor) 44, and the diameter sensor 43. When determining that the conveyed coin C is a genuine coin, the CPU 121 does not drive and control the reject solenoid 52, and the reject shutter 51 is kept closed. Therefore, the coin C is conveyed to the coin sorting unit 13 without falling from the reject hole 33a. On the other hand, when determining that the coin C to be conveyed is not a genuine coin, the CPU 121 controls the drive of the reject solenoid 52 to open the reject shutter 51. Thereby, what is identified as other than a coin determined not to be a genuine coin (for example, a forged coin or a toy coin) falls from the reject hole 33a and is stored in the reject box 53.

  In the coin sorting unit 13, the coins C are conveyed by the sorting belt 63, dropped from the corresponding sorting holes 64, and stored in the coin storage unit 14. At this time, the sorting belt 63 and the reference surface 66 are arranged so as to approach each other as they go downstream in the coin conveyance direction, so that the sorting belt 63 presses the side surface of the coin C against the reference surface 66 while The coin C is conveyed.

  When there is a coin payout instruction from the POS terminal, the CPU 121 drives the payout belt 101 and drives the payout solenoid 108 for each denomination to pay the required number of coins to the coin payout exit 109. put out.

  Thus, according to the present embodiment, the transport base 33 having the coin transport surface 31 for transporting the coin C, the transport belt 32 for transporting the coin C on the coin transport surface 31, and the coin transport surface 31 side are provided. The first coil 48a, 48c and the second coil 48b, 48d provided on the opposite side of the coin transport surface 31 are supported.
