PURPOSE: To realize the automatic selective setting for each action of the tape recorder by driving the timing wheel which controls the rotary switch via the driving gear driving constantly and thus controlling the selective setting of actions.

CONSTITUTION: The rotation of driving gear 1 turning constantly is transmitted to intermediate gear 6, and thus timing pulley 9 which is pressed to gear 6 is turned by the friction force. As a result, search lever 17 shifts along set lever 8. On the other hand, plunger 13 is excited by the switching caused by conductive substrate 9c and rotary switch 9b which turns along with pulley 9. And thus the rotation of pulley 9 and the shift of lever 17 are stopped via engagement setting part 9a between timing lever 12 and pulley 9. Then tip 17b of lever 17 is fixed to the area of the record setting plate of setting plate group 18 to secure the automatic selection for the recording action and the like. In the same way, the automatic selective setting can be given to the reproduction, rewinding and others.
