<p>PURPOSE:To obtain a tape loading mechanism which is easily attaining the miniaturization of a device, is capable of reducing the number of parts and attaining high reliability. CONSTITUTION:A cam gear 106 having an intermittent gear part 107 in an outer peripheral part and a cam groove 108 in a middle part are provided freely and rotatably to a deck base 1, and the intermittent gear part 107 transmits the torque from a driving source and loads a tape pulling-out members 7 and 8, then the cam grooves 108 and 109 execute loading and press-contact of a pinchroller 18. Also an intermittent gear part 111 engaged with the cam gear 106 and a clutch gear 110 having an engaging part 113 capable of coming into contact with a stopper 112 on the deck base 1 are provided and disengaged with the cam gear 106 after the compeletion of the loading of the tape pulling members 7 and 8, but the engaging part 113 of the clutch gear 110 is depressed to the stopper 112 since the direction of the reaction force of the depressing force the tape pulling member 7 and 8 passes through the rotation center on the halfway of rotation, and the depression of the tape pulling members 7 and 8 is maintained.</p> |
