ABSTRACT:
A hopper device has an insulating hopper member. A first electrode is mounted in the inner side of the hopper member in a lowermost portion thereof, and at least one second electrode is mounted in the inner side of the hopper member in a portion thereof at a higher level than the first electrode. When coins having conductivity are collected in the hopper member until their level reaches the second electrode, the first and second electrodes are electrically coupled together by the coins, whereby an electric signal representing the amount of collected coins is generated.
