<p>PURPOSE:To simplify the constitution and improve the operability by attaching turnably a moving lever, to which the rotating force is transmitted from a cam gear at the operation time of depression of a play button and which releases lock of the cam gear at the non-operation time, to a driving lever. CONSTITUTION:A tape recorder is provided with pinch rolls to be press-fitted to capstans 7 and 8 and an intermediate gear mechanism which is switched to be engaged with a supply side or take-up side reel base gear, and a cam gear 19 which is rotated while interlocking with a gear 7a of the capstan 7 for FWD. A driving lever 40 is provided which not only is switched and turned by the rotation of the gear 19 to press-fit pinch rolls to capstans but also operates the track switching of a magnetic head. A moving lever 44 is attached turnably to the lever 40. At the operation on time of depression of the play button, this lever 44 is set to the detained state, and the rotating force is transmitted from the gear 19 to the lever 44 so that the pinch roll for REV is press- fitted to the capstan 8 for REV; and at the non-operation time, the lever 44 releases lock of the gear 19. Thus, the constitution is simplified, and the operability is improved.</p> |
