Abstract

PURPOSE:To reduce the amount of the power consumption and thus to make sufficient the power supply with the power given from the exchange by actuating the coin supervisory unit above the storage lever only at the moment when the charging signal ends. CONSTITUTION:Charging signal reception circuit PSR produces the H-level output covering the start and end of reception. The voltage change is differentiated via capacitor C8 and resistance R18 at the end of the charging signal, and and this output is applied to NOR2 to switch on transistor Tr6 thus to give the light emission to luminous element EL1. In this case, if the coin exists above the storage lever, photo detector PT1 is kept off. And pulse generator PG1 is driven via AND3, NOR4 and NOR6 each, and then transistor Tr1 is switched off to block the call. Thus no existence of coins is checked immediately after the charging signal to confirm whether or not the queuing coin is stored or not. Furthermore, the amount of the power consumption can be reduced since EL1 has light emission instantaneously.
