<p>PURPOSE:To drive a pinch roller arm in an interlocking way with a sub-roller arm connected with a driving source. CONSTITUTION:A sub-roller arm 21 which supports a winding-side sub-roller 11 which becomes part of a tape guide member for pulling out a magnetic tape T from a cassette 3 is coupled with a control cam gear 34 which becomes a rotationally driving source through a joint 73 and toggle lever 74. A pin 21b protrudes downward from the front end of the arm section 21a of the arm 21 and is put in a cam groove 20b provided on a pinch roller arm 20 supporting a pinch roller 10. The pinch roller 10 positioned in the cassette 3 is taken out from the cassette 3 by rotating the pinch roller arm 20 in an interlocking way with the rotation of the sub-roller arm 21.</p> |
