マ装置。[Claims for Utility Model Registration] (1) A power switch connected between a heater and a power source, a time constant circuit consisting of a capacitor and a resistor to which voltage is applied when the power switch is turned on, and a time constant circuit that is configured to turn on the power switch. A switching circuit that is turned on during operation and turned off when the capacitor of the time constant circuit finishes charging; and a relay that holds the power switch in the on state when the switching circuit is turned on and turns off the power switch when the switching circuit is turned off. A timer device for a roaster, characterized in that the switching circuit has a PUT for detecting the end of charging of the capacitor of the time constant circuit, and a heat sensitive element is provided in the gate circuit of the PUT. (2) A utility model registration request characterized in that the heat-sensitive element is a positive characteristic thermistor, and the thermistor is connected to the anode side of the reference voltage applied to the gate circuit of the PUT of the switching circuit and the gate of the PUT. A timer device for a roaster according to item 1.
