<p>PURPOSE:To reduce the weight of the entire device by providing a 1st motor driving a rotary head cylinder for signal recording and reproduction in forward/ reverse direction and a 2nd motor driving a capstan in both directions. CONSTITUTION:When a reproducing button is depressed, a cylinder motor 2 is being driven in a direction A to drive a pulley 6 counter clockwise via a belt 5 but delivers no torque to an operating part 6b by the action of a built-in unidirectional clutch. Thus, a slider 8 is not moved to keep the engagement between an end 11 and a recessed part 45a of a missing-tooth gear 41, an end face 52 of a lever 51 is abutted with a large diameter of an end face cam 43 and a capstan motor 22 is driven in the direction C, but the gear 41 is not driven. a torque of the motor 22 drives a clutch gear 59 through gears 27, 57, 55 clockwise and since the gear 59 meshes with a gear 71 in this case, the gear 71 is driven counter clockwise, a loading ring 74 is a driven, a guide post is drawn to be wound on a cylinder 1.</p> |
