Abstract

PURPOSE: To make it possible to perform automatic switching operations easily and surely even by a small-capacity electric power source, by making it possible that a driving pinion gears into the tooth part of a gear lacking in tooth lightly even for instantaneous energizing of an electromagnet.
CONSTITUTION: Before the switching unit operates, that is, when the tape recorder is set to the operation mode, pinion 5 rotates. Since lever 20 is pulled by spring 21, arm 12 is brought into contact with linear part 9b of cam 9 to stop rotation of gear 8 lacking tooth. Now, when a current is flowed to coil 19 instantaneously for reproducing, the end of bending part 17a of the iron core is magnetized to the N-pole and the end of standing piece 15 is magnetized to the S-pole. Then, N-poles of the end of bending part 17a and magnet 10 repulse each other, and magnet 10 starts rotating counterclockwise by this repulsive force, and tooth part 8a of gear 8 lacking in tooth gears into pinion 5, and gear 8 is rotated forcedly, thus executing operations of the switch.
