Abstract

PURPOSE: To make it possible to prevent the erroneous setting of a timer while simplifying the constitution by permitting an external operation switch, needed for timer time setting, to serve as a monitor display switch for the contents of a timer times as to a timer clocking circuit, etc.
CONSTITUTION: With mode change-over switch S2 of an electronic timepiece pushed in time display mode, display change-over circuit 7 is changed over through D type FF, etc., of input control circuit 4 to select the timer time display mode. With a pulse generated as rotary switch SB-N is turned in accordance with the turning of its crown, an up-count signal and timer-time latch signal are spplied to timer counting circuit 5 and latch circuit 6 by way of circuit 4 to set a timer time and latch contents of circuit 6 are digitally displayed on display unit 9 by way of circuit 7. Therefore, timer-time setting and timer-time monitor display are controlled by the same external switch and the constitution is simplified, preventing the erroneous setting of the timer.
