<p>PURPOSE:To prevent damage of a tape and deformation of a pinch roller securely by making it possible to force a support plate (P lever) having a head, pinch roller, etc., arranged to return to a stop position manually. CONSTITUTION:If P lever 21 is at the playback side and a battery voltage, for example, decreases below a fixed value to disable P lever 21 to return by a motor, operation switch 18 on the flank of main body 1 is slid. Then, lever 33 moves along slit 331 by pins 341 and 342 and P lever 21 is rotated clockwise against the displacement force of spring 28. Next, P lever 21 has pin 342 hooked in hook hole 332 as shown by (c). As a result, P lever 21 is forced to return to the stop position. Therefore, this constitution enables the P lever to return to the stop position forcibly with the manual operation switch, so that the damage of a tape and the deformation of the pinch roller can securely be prevented.</p> |
