<p>PURPOSE:To match correctly the timing of the release of a cassette holder and the ejection of a cassette by releasing the cassette holder with the shifting of one direction of a slider and closing the cassette holder only with the shifting of the reverse direction of the slider. CONSTITUTION:When a slider 3 retreats, a ratchet arm 26 supported with a shaft in one side of sliders 3 and 3 retreats, an engaging piece 26a is abutted on a projection 28a of a slider driving arm 28 and the arm 28 is turned in the counter-clockwise direction. By the rotation of the arm 28, a slider arm 29 is turned by an engaging projection 28b, a cassette ejecting plate 30 freely slidable to a chassis 1 is advanced against the force of a spring 31. Since the ejecting plate 30 is positioned at the aperture part of the first and second cassette holders 22 and 23, when the ejecting plate 30 is advanced, the tip is inserted into the first and second cassette holders 22 and 23, when the cassette is mounted in the cavity, the tip is abutted on the front surface of the cassette and this is pushed out.</p> |
