<p>A driving mechanism for a tape recorder having a magnetic head and pinch roller having a first solenoid actuated plunger, said magnetic head and pinch roller being movable into and out of an actuating position by a lever associated with said first plunger, compact second and third solenoid actuated plungers forming operational modes of quick feeding and rewinding, a slider plate movable in opposite directions by said second and third plungers, a transmission mechanism connecting a drive source respectively with a supply reel and a take-up in the operation of said second and third plungers, a locking mechanism retaining a sliding position of said slider by operation of said first plunger and a lost motion mechanism adapted to inhibit the operation of said pinch roller at least in the operation of said second and third plungers, can form the operational modes of quick feeding and rewinding of the magnetic tape only by the use for triggering the operation of said compact plungers instead of larger ones to reduce power consumption through the miniaturizations of power transformer and miniaturize the whole tape recorder.</p> |
