ABSTRACT:
A device for counting coins of different diameters and similar disk-shaped objects which are conveyed in irregular sequence. The edges of the coins contact a guide edge on a guide track which has a scanning head located therein for identifying the coins. An electronic evaluation and display unit receives the identification signals delivered by the scanning head. The scanning head has several electronic proximity sensors located at different distances from the guide edge. The paths of motion of the edges of coins away from the guide edge, run in the active areas of the proximity sensors which provide substantially clear identification signals distinguishing the coins to be identified. The diameter of the proximity sensors is approximately half the diameter of the smallest coin to be identified, and the several proximity sensors are located at different distances from the guide edge. These distances are determined by the paths of motion of different coins. The sensors, furthermore, may be staggered along a line perpendicular to the guide edge. The electronic proximity sensors, moreover, may be located one behind another in the direction of motion of the coins.
