ABSTRACT:
An arrangement for counting the values of different-denomination coins and other disk-shaped objects in which the coins are transported in an irregular sequence with their rims along a rectilinear guiding edge on a guide track. A scanning head identifies the coin, and is located at the start of the rectilinear guiding edge. The scanning head has several photoconductor strands having free ends located at varying distances from the guiding edge. Photocells are connected to the other ends of the strands, and a light-beam element illuminates the free ends of the photoconductor strands. The photoconductor strands and the light-beam element are separated by a scanning gap for passage of the coins. The photoconductor strands are located along a line perpendicular to the guiding edge inside a holder which is inserted in the guide track. The free ends of the photoconductor strands are flush with the surface of the guide track. One photoconductor strand is associated with each of the coins of varying diameter.
