Abstract

PURPOSE: To accurately display time and prevent generation of sound at altering set time in an alarm device for a hand display type electronic watch by simultaneously generating sounds for intended switch off state storage, on state and standard pulse as three signals.
CONSTITUTION: OFF of a standard switch M is set through an inverter 42 and stored in a flip-flop FF43 not reset even if the switch M is turned ON to thus cause the flip-flop FF43 to generate high level output. When the switch M is turned ON in the vicinity of the alarm time, high level ON signal is applied to an AND gate 45 applied with OFF storage signal from the flip-flop FF43 to open the AND gate 46 through the gate 45. Initial standard pulse signal formed by a one-minute digit counter 39 and a differentiator 40 is applied to this gate 46 to generate an alarm at accurate time only when the OFF storage, ON and standard pulse signals are simultaneously existed. Even if the switch M is turned ON at the alarm time set altering time, the counter 39 is reset not to generate the standard pulse therefrom to thereby generate no alarm sound.
