<p>PURPOSE:To attain miniaturization, light weight and low cost by providing a pinch roller to one end an arm pivoted to a lid, and an abutting part to the other end to abut a cam follower and a cassette tape front edge, and providing a cam to the main body so as to press a pinch roller and a capstan shaft into contact with each other at prescribed pressure. CONSTITUTION:When the lid 3 is opened, a dowel 450 is engaged with a cam face 62 and the pinch roller 5 is parted from the capstan shaft 4. In loading a cassette tape C from the inserting part of the lid 3, the front edge pushes a trigger pin 47, but since a cam 8 and the dowel 450 are engaged, the pinch roller 5 keeps the position and a tape T is inserted smoothly. When the lid 3 is closed, the dowel 450 is displaced backward by the operation of a cam face 63, the pinch roller 5 is pressed into contact with a capstan shaft 4 while clipping the tape T, but since the stroke until the pinch roller 5 is pressed into contact with the capstan shaft 4 is shorter than the stroke of the trigger pin 47, a spring 43 is reduced by the difference of the strokes is reduced by the depression of the tape C and the pinch roller 5 is pressed into contact with the capstan shaft 4 by the elastic force.</p> |
