<p>PURPOSE:To control the running without using a plunger, by operating any one of head mechanisms with the control of a driving section, locking the driving section at the end of switching of a slider, and restoring the slider and the driving section to the stop position at the release of lock. CONSTITUTION:In case of the forward reproduction, a main gear cam 41A is driven counterclockwise, a projection A4 depresses a right reproducing slider 47C and slides it toward the G. The slider 47C depresses a head slider 48F and slides it toward the G. A recording/reproducing head 55I contacts a tape surface, and a right pinch roller 52 contacts with a right capstan 54. In this case, an assistance motor 42 is locked. When the motor 42 is stopped to make the operation stop, the head slider 48F is retrogressed toward the H with a spring 76, a right reproducing slider 47C is retrogressed toward the H with a torsion spring 74E and restored to the stop position. In this case, the cam 41A is rotated accompanied with the retrogress of the slider 47C and restored to the stop position.</p> |
