Claims

[Claims for Utility Model Registration] (1) A rotary drive unit constituted by a rotor consisting of a coil, a fixed iron core, and a permanent magnet, a plurality of gears that transmit the rotation of the rotor and control operating time, and a plurality of gears that transmit rotation of the rotor and control operating time; A gear case incorporating gears, and the rotation transmitted by the plurality of gears turns on and off a switch circuit composed of a plate contact piece and a resistor for overcurrent protection to the coil. What is claimed is: 1. A timer device comprising: a cam that rotates; and a switch case incorporating the switch circuit and the cam, characterized in that the rotation drive section is provided inside the gear case. (2) Utility Model Registration The timer device according to claim 1, characterized in that a pinion engaged with a gear portion of a cam is provided with an idling mechanism during forced rotation.
