<p>PURPOSE:To attain miniaturization, light weight and low cost by supporting a pinch roller to one end of an arm member whose intermediate part is supported to a lid, providing a cam follower to the other end and opening/ closing the lid in engagement with a can provided to a main body to separate or abut the pinch roller from and on a capstan shaft. CONSTITUTION:When the lid 3 is opened, a dowel 450 engages with the 1st cam face 62 and the pinch roller 5 is at a position parted from the capstan shaft 4. In loading a cassette tape C from the insertion part of the lid 3, the front edge is pressed into contact with a trigger pin 47 and acts on it in the pushing direction, since the cam 8 and the dowel 45 are engaged with each other, the pinch roller 5 keeps the same position. In closing the lid while the cassette tape C is being pressed next, the pinch roller keeps the preceding position just before the closing and the tape T is inserted smoothly. When the lid 3 is closed, the dowel 45 is displaced backward by the operation of the 2nd cam face 63 and the pinch roller 5 is pressed into contact onto the capstan shaft 4 while the tape T is clipped. Thus, the operating system is simplified.</p> |
