ABSTRACT:
A coin distinguishing mechanism, installed preferably in a coin keeper, capable of discriminating coins of varying denominations and adding up the total value of the coins being kept therewithin. The coin distinguishing mechanism includes a coin slot means having a passageway which is defined on one side by a fixed element and the other side by a movable element. The movable element is generally kept to the same position by an elastic means. As the movable element is forced to move by a coin passing through the passageway, the moving distance will be magnified by a magnifying mechanism, and an attached arm with a conductive wiper having a first and a second contact ends is thereby actuated. The conductive wiper moves, for a distance magnified in accordance with the moving distance of the movable element, and makes contact on a circuit board by its two contact ends to generate signals indicating the denomination of the inserted coin to a circuitry for displaying the denomination of each insertion as well as calculating the total value of the coins in the coin keeper. The circuit board can detect the inserted coins of various diameters precisely by the specific contacts made by the conductive wiper.
