The coin sensor 24 performs a function of determining whether the coin is normally distributed or a forged coin. That is, the coin sensor 24 determines whether the coin is a domestic unused coin, a foreign coin or a counterfeit coin so that the coin can be returned if it is not a normal coin. In addition, in the case of a normal coin, the coin sensor 24 may perform a function of identifying the winding type of the coin. Such a coin sensor 24 typically identifies the coin by irradiating the coin with a magnetic field and receiving a signal value reflected from the coin. Examples of such a coin sensor 24 are disclosed in Japanese Patent Application No. 2001-126103, Japanese Patent Application No. 2002-024894, US Application Publication No. 2005/0150741, and the like.

The controller 80 analyzes information about coins sensed by the coin sensor 24 and determines whether the coin is a return target coin (S606). In the case of normal coins that are not subject to return, the coins are continuously moved to the coin transport path 20 and collected in the coin collecting port 30.

When the coin corresponds to the return object, the controller 80 operates the return protrusion 26 to release the coin from the normal transport path so that the coin is returned to the coin return port 28 (S608).

After ending the sorting function for the put coins, or after a predetermined time has passed after the coins are put, the controller 80 determines that the sorting of coins has been completed, and discharges the coins remaining on the rotating disc 16. In order to operate the coin discharge unit (7) (S610). The control unit 80 opens the hopper cutout 60 by operating the drive link operating device 72 of the coin discharge unit 7 to operate the open / close link 62 driven by the drive link 68. At this time, it is preferable to rotate the rotating disk 16 so that coins that may be caught in the coin discharge groove 18 may be completely discharged to the coin discharge port 74.

After the above process is finished, or at the same time as the step S610, the controller 80 displays the sum of the normally collected coins on the display 84 (S612).
