<p>PURPOSE:To miniaturize the titled sound recording mechanism, by separating an erase head from a magnetic tape in a reproducing state and sliding rightward and leftward a rack lever which slides rightward and leftward at the time of reproducing operation by engaging an REC tying lever with the rack lever at the time of sound recording. CONSTITUTION:When a motor 13 is rotated in the direction F and adhesion by adsorption between a plunger 27 for reproduction and another plunger 28 for sound recording is released, an F rack gear 17a and F rack driving gear 11 are engaged with each other and a rack lever 17 starts to slide in the direction A. Simultaneously, the pin 28a of the plunger 28 pushes an REC tying leer 25 by means of the forcing force of a spring 36 and the lever 25 is turned in the direction E, with a shaft 25a acting as a fulcrum. As a result, a typing click is engaged with the pin 17f of the lever 17. The lever 17 further slides in the direction A and the lever 25 also slides in the direction A. Under this condition, the pin 23a of a forward path erasing head operating lever 23 is pushed by the lever 25 and the lever 23 is slid in the direction C. Therefore, the forward path erasing head is brought into contact with a magnetic tape with pressure.</p> |
