<p>PURPOSE:To load a small cassette at a prescribed position without using any adaptor at the cassette inserting position by securing such a constitution where the cassette insertion detecting members set at two different areas are actuated together with a lock member interlocking these detecting members when the small cassette is put into normal position and then a cassette insertion inhibiting cover members is opened. CONSTITUTION:When a small cassette 30 is put into a rough inserting position which is coincident with each reel drive disk, the cassette insertion detecting members 35 and 36 are turned toward an arrow head C with bearing pins 33 and 34 defined as rotational fulcrums by the cassette inserting force. At the same time, the lock members 41 and 42 interlocking drive pins 37 and 38 are turned toward an arrow head F with drive lever shafts 39 and 40 defined as rotational fulcrums. Thus a positional relation is secured to avoid a countering state to the tip part of a cassette insertion inhibiting cover member 44. Thus, the member 44 can turn toward Q to allow insertion of the cassette. In such a way, the cassette 30 can be set into a prescribed position with no use of an adaptor, etc., under the conditions where both large and small cassettes are used.</p> |
