<p>PURPOSE:To simplify a constitution by forming a reel base with a rotation moving system and making a rotation center of a member moving the reel base to coincide with a rotation center of a member moving the member. CONSTITUTION:Positioning pins 4, 5 for combined use for a large cassette 1 and a small cassette 2, positioning pins 6, 7 for private use for the large cassette 1 and positioning pin shafts 8, 9 for private use for the small cassette 2 are provided on a chassis 3. The reels 120, 121 are freely rotatably supported by reel base moving members 124, 125 through reel base shafts 126, 127. The movement members 124, 125 are made freely rotatable around the pin shafts 8, 9. A movement member 141 is freely rotatable around the pin shaft 9 and the movement members 124, 125 are rotated by this movement. By this constitution, the movement from the large cassette 1 to small cassette 2 and the positioning are performed by rotating the movement member 141 in the direction of W around the pin shaft 9 and by making the movement member 141 to move in the direction W reversed from that at the loading time of small cassette 2 when the large cassette 1 is loaded.</p> |
