Abstract
PURPOSE: To make possible plural kinds of timer operations such as set time and once every fixed time by setting arbitrary digits of time as timer time, comparing only the set digits with the current time and generating a coincidence output.
CONSTITUTION: When the digits of the hour are selected by a select switch S3 and a set switch S1 are operated, the hour set by a setting device DS is sent in a memory circuit M1. In the similar manner, the setting of the minute digits and second digits is accomplished in memory circuits M2, M3 respectively. The respective digit set times of the hour, minute and second of the circuits M1WM3 and the respective digits of the hour, minute and second of the momentary time of clock circuits C1WC3 are compared in comparators P1WP3 rspectively and the coincidence outputs of the circuits P1WP3 are generated from a gate circuit G, thus at every set time, the timer output is generated everday. On the other hand, if only the second digits are set by the switch S3, the timer output is generated at every one minute by the circuits M3, D3, and in this way the watch capable of performing various timer operations is provided.
