Abstract: An inventory device which is used for a route-man to take all the coins out of the coin containing cylinders of an automatic vending machine. With the inventory device, the coin containing cylinders are caused one after another to dispense the coins merely by operating a single switch. The inventory device comprises: the single switch; a shift register; and a coin dispensation control section connected to the bit output of the shift register. The signal "1" is successively shifted in the shift register in response to the operation of the single switch, to operate the coin dispensation control section, thereby to dispense the coins out of the coin containing cylinders.

Abstract: In a coin counting device for an automatic vending machine, the outputs of counters adapted to counts the number of inserted coins separately according to the denominations of the coins are multiplied by the factors which are set by setting circuits separately according to the denominations, respectively, to obtain the total amount of money of the inserted coins. The factors can be changed according to the denominations of coins to be handled by the automatic vending machine, without modifying the circuitry, so that the device can handle coins of any denominations.
