Coin sensing apparatus



The coin sensing device comprises a micro computer (6), an oscillator (7) oscillating a constant pulse to be inputted to the computer, a sensing section for sensing th data about material, thickness, diameter of the dropped coin, a comparator (13) for comparing the material sensing data (S1) of the sensing sect., a data transmitter (5) for transmitting the data relating to the coin material, and the data about the coin thickness and diameter, and a counter (2) converting the data about coin material, thickness, and diameter to 4 bit data. The coin sensing device has a sensing sect. (3) sensing the pass of coin, a gate part (4), a port sensor (PH1,PH2) sensing the clogging of the coin, a reset part (8).
