Method and apparatus for discriminating and collecting coins

A method and apparatus for discriminating and collecting coins wherein an inserted coin is received in a notch of a rotary disk. Upon sensing the insertion of a coin into the notch, a motor rotates the disk through a predetermined arc to a predetermined angular orientation where a decision is made whether to accept or reject the coin based on coin characteristics such as the sensed diameter of the coin and metal content. If the coin is accepted, the disk is rotated to an angular orientation where the coin falls from the notch into a coin collection box. However, if the coin is rejected, the disk is rotated in the opposite direction to an angular orientation where the coin falls into a coin return chute. Sensors are also provided to sense the presence of the coin in the notch on the way back to the initial angular orientation. If the coin failed to fall out for any reason, another attempt is made to collect the coin. If still unsuccessful, a fault is indicated, and the apparatus remains in an inoperative state. Removal of the coin from the coin return chute is also sensed before another coin can be inserted.
