Abstract

PURPOSE:To simplify constitution by reducing parts in number by activating a cassette holder toward a set unit by one spring and then by activating a hook member in a cassette ejection direction. CONSTITUTION:At ends of spring hook piece 25 of hook member 4 and interlock member 5, respective ends 27a and 27b of expansion spring 27 are hooked. When cassette holder 2 is placed at the set position, one terminal 27a is upper and the other terminal 27b is lower to press cassette holder 2 against fixed substrate 1, but the force of activating hook member 4 in the cassette ejection direction is extremely slight. As holder 2 is turned toward the reset position, the other terminal 27b of spring 27 raises to accumulate power at spring 27, and the rotational force of hook member 4 in the cassette ejection direction increases gradually. Therefore, when holder 2 rises up to the reset position and the front edge of holder 2 is detached from hook piece 23, hook member 4 moves powerfully in the cassette ejection direction to move hook piece 23 toward the reverse surface of holder 2 and then stops with push-out piece 24 in contact with the bottom surface of concave part 2b of holder 2.
