Abstract

PURPOSE:To simplify the lock reset operation as well as realize a cost reduction, by making the second reset switch double the lock reset means. CONSTITUTION:To correct the hour, both hour and minute correction switches Sh and Sm are first closed simultaneously along with AND gate A1 opened and the FF set each. Then switch Sh is closed with AND gate Ah opened, and 1-second pulse 1s is produced at the output of gate Ah in the form of hour correcting quick setting pulse 1h. After correction of the hour, second reset switch SR is closed with the FF reset and the electronic locking given. In the case of the minute correction, both switches Sh and Sm are first closed simultaneously. Then AND gate Am is opened to perform the quick setting by output 1m. After correction of the minute, the FF is reset by switch SR with the electronic locking given. Thus the subsequent malfunction can be prevented.
