<p>PURPOSE:To reduce the weight of a tape cassette holding spring and also to hold stably a cassette in a loading state by making an ejection spring which pushes back the cassette in the draw-out direction serve as a cassette holder as well. CONSTITUTION:An ejection spring 18 which pushes back a tape cassette 12 in the draw-out direction is hooked between an ejection member 16 and a spring holding member 15. An interlocking member 34 is always energized counterclockwise by a cassette holding spring 41. When a tape cassette 12 is loaded, the force of the spring 18 acts on the member 34 in the counterclockwise direction together with the force of the spring 41. Thus the cassette 12 is turned toward a substrate 1. As a result, the weight of the spring 41 can be reduced and simultaneously the cassette 12 can be held stably by a loading device.</p> |
