<p>PURPOSE:To easily execute a design of a supporting mechanism for inserting a cassette by constituting it so that a cover does not fall off even in the case a vibration shock is applied, to say nothing of a rotational, operation of the cover. CONSTITUTION:A rotation axis 2 of one end of a cover is inserted into a receiving hole 7 of the rotation axis of a front panel outer edge 10A so as to be freely turnable, and a rotation axis 3 of the other end is inserted into a receiving hole 8 of the rotation axis provided with an opening end of the front panel outer edge 10A so as to be freely turnable and attachable/detachable. To this rotation axis 3, a torsion coil spring 5 is wound round. The torsion coil spring 5 is energized in the direction for closing the cover 4. A claw part 15 which is engaged to at least one of end parts 5a, 5b of the torsion coil spring 5 and prevents falling-off is projected and provided from the front panel face 10a.</p> |
