ABSTRACT:
A coin selector for use in a coin mechanism of vending machines and the like is disclosed. The coin selector includes a device which determines whether a deposited coin is real or fake, and a movable gate which selectively conducts the deposited coin into a real coin chute or a fake coin chute in response to an operational result of the determining device. A detector is positioned upstream of the entrances to the real coin chute and the fake coin chute, and outputs an electrical signal which is dependent upon the position of the gate and the moving condition of the coin as it passes by the detector. The coin selector further includes a judging circuit which receives the output from the detector and determines whether the gate is in position to conduct the coin into the real coin chute or the fake coin chute. The judging circuit independently determines, based on the assumption that the gate is position to conduct the coin into the real coin chute, whether it can be concluded that the coin was in position to go into the real coin chute. If it is determined both that the gate was in position to conduct the coin into the real coin chute and that the coin was in position to be so conducted, the judging circuit outputs a signal indicating that the coin went into the real coin chute.
