<p>PURPOSE:To raise reliability of an eject operation by making a pressure gear press-contact with a fly-wheel as a tape guide post moves, and limiting a rotation range by a gear having a prescribed number of teeth. CONSTITUTION:At the time of an unloading state, a guide post 28 presses a pressure receiving part 31, moves a slider 30 in the direction A, and a pressure gear 5 is made to press-contact with a fly-wheel 2. When an eject button is pushed, rotating force of a capstan driving motor rotates the fly-wheel 2 counterclockwise through a belt 1, a three piece gear 7 of the pressure gear 5 is engaged with a gear 4 of the fly-wheel 2, a pressure part 6 of the pressure gear 5 presses a link member 11, a pressure part 13 moves a slider 15 in the direction B, and a pressure part 29 is rotated in the direction C. A pressure piece 20 is fitted into a groove hole 24, a detaining member 22 is rotated in the direction D, and a pawl piece 23 provided on a cassette holder 26 is pushed up in the upper direction by a spring 33.</p> |
