Claims

[Claims for Utility Model Registration] A reference switch that is turned on when it detects that the time displayed by a clock circuit has reached a preset time, and an indicator switch that is turned on and off by an external operation and that only when it is turned on. an alarm set switch that validates the on signal of the reference switch; a sleep counter that counts a fixed periodic signal from the clock circuit and generates an output signal after a fixed period of time only when the alarm set switch is in the on state; and a sound memory circuit that stores sounds for sleep and sleep respectively and selects a sound for alarm when the indicator switch is on; and a gate circuit that enables the sound storage circuit to operate only when the sleep counter is counting, and a sound generation circuit that produces sound based on the sound signal from the sound storage circuit, the watch with a sleep function as described above. a trigger circuit that generates a trigger signal each time an alarm set switch and a reference switch are turned on; and a trigger circuit that shifts an output according to the number of times a trigger signal is generated from the alarm set switch and generates a trigger signal each time a trigger signal from the reference switch is generated. A timepiece with a sleep function, comprising: a shift register that returns to an initial state; and a volume variable circuit that varies the volume of sound from the sound generation circuit in response to the output of the shift register.
