<p>PURPOSE:To prevent the interferences of a shutter and a pressing member while positioning a pressing member for pressing a cassette at an optimum position without folding the shutter by providing a notch avoiding the butting of the cassette and the pressing member in the shutter. CONSTITUTION:At both end sections in the transverse direction of a shutter 21, from an end section 212 opposed to an end section 211 in which a rotating fucrum M is disposed, notches 22, 23 are formed toward the end section 211. On starting to mount a cassette, even if the shutter is rotated from a first position A to a position B, cassette pressing members 24, 25 placed in the vicinity of an inserting opening of the cassette pass through the notches 22, 23 and do not butt with respect to the shutter 21 disposed at the second position B, the cassette pressing members 24, 25 together with a cassette holder are moved to the cassette inserting opening side (X2 side), they do not butt with the shutter 21 since the notches 22, 23 formed from the end section 212 of the shutter 21.</p> |
