<p>PURPOSE:To make the constitution of a tape recorder simple and small-sized, by utilizing the rotatory power of a motor to control the high-speed running operation of a tape. CONSTITUTION:When the engagement due to a lock lever 88 which is operated in accordance with a solenoid 89 for fast-forwarding is released, a driving pulley 86 is turned clockwise by the elastic force of a spring 87. Then, a fast-forwarding driving lever 70 is turned counterclockwise, and a fast-forwarding rod 86 and a fast-forwarding lever 58 interlock to forward a take-up reel base 12 fast through a fast-forwarding gear 61, a large gear 4, etc. Simultaneously, a head base is inter-locked with the rod 86 to be moved in the direction where the head is separated from the tape. When this solenoid 89 is released, the pulley 86 is turned through the lever 70, a cam 86a as one body, etc., and a gear part 86 of the pulley 86 having a tooth lack part and an electric driving gear 69a bite each other to rotate the pulley 86 once, and similarly, the pulley is transferred to the stop state. The rewinding is performed similarly. By this control for the tape high-speed running operation utilizing the rotatory force of the motor, the tape recorder is simple and small-sized.</p> |
