  • Patent number: 4364404
    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.

  • Patent number: 4347924
    Abstract: The control system for a vending machine according to the invention is designed for preventing shortage of change coins to a maximum possible extent. According to the control system, as many coins of a low denomination as possible among coins inserted by a purchaser are collected for use as change coins. The control system further includes, in addition to main tubes to which inserted coins are automatically supplemented, auxiliary tubes to which coins are manually supplemented by a supervisor of the vending machine.

  • Patent number: 4108296
    Abstract: A coin receiving apparatus for a vending machine capable of accurately checking a coin diameter as well as other coin characteristics such as material and a surface pattern for discriminating a true coin from a false one and receiving the former and rejecting the latter. The diameter and other coin characteristics are detected by examining peak values of output waveshapes of coin detectors by means of a window circuit. A single window circuit is provided for each denomination and upper and lower limit values of the window circuit are automatically changed in accordance with a coin characteristic under examination. Frequencies of excitation signals of the various coin detectors are also automatically changed. If a plurality of coins are successively inserted in the coin receiving apparatus without a sufficient time interval, discrimination of the inserted coins is inhibited and the inserted coins are returned.
