<p>The coin processing device consists mechanically of a manually operated cam which sets a position according to six possibilities so that three microswitches may have their contacts either closed or open according to the coin value to be counted. In the electronic circuit, the microswitches (3, 3', 3") have a common 5 volt. supply connection and have a rectangular matrix connection from the contacts (a, b) through diodes passing contacts (a, b) of three further 3-pole switches (24, 24', 24"; 25, 25', 25"; 26, 26', 26") with a common connection each to a resistor and a light emitting diode (32, 33, 34), with common earth terminals on the low volt. side. The three output side switches (W1, W2, W3) are operated by a motor driven lever arm connected to a counting cam, so that the appropriate diode(s) are illuminated each time a specified coin value passes through. The demonstration system is for the Japanese coins 100, 50 (new) 50 (old) 10, 5 and 1 yen.</p> |
