ELECTRONIC TIMEPIECE

摘要

An electronic timepiece which can reduce currents flowing in a pull-down resistor or a pull-up resistor when a crown switch is turned on includes a first switch that is connected to a signal line, a second switch, and a one-shot pulse signal generation circuit. The first switch is inserted into the signal line. One end of the second switch is connected to the signal line on a rear stage of the first switch. The other end of the second switch is connected to a power source. The one-shot pulse signal generation circuit generates a one-shot pulse signal by using a reference clock signal. The second switch is controlled by the one-shot pulse signal.
