Claims

[Scope of utility model registration request]

a reference frequency generation circuit, a frequency dividing circuit, a time unit pulse creation circuit that creates unit time pulses from the output signal of the frequency division circuit, a time counting circuit that counts the time unit pulses, a data holding circuit, and a data holding circuit. A circuit device comprising a coincidence detection circuit that compares data held in the holding circuit and data in the time counting circuit and outputs a coincidence signal, and a control circuit operated by the coincidence signal, and supplies power to the circuit device. It is composed of a battery, a sounding body driven by the control circuit, and a time setting device for inputting a set time into the data holding circuit, and the reference frequency oscillation circuit is activated by the first operation of the time setting device. , the circuit device and the battery are disposed in one of the first and second housing members, which are constituted by an on/off control oscillator that stops when the sound generation signal from the circuit device ends, and are movable relative to each other in the axial direction. An electronic timer comprising: a sounding body and a time setting device; the time setting device is actuated to set the timer time by relative operation;
