<p>PURPOSE:To position a cassette holder main body at a desired position with respect to a chassis by shifting a turning phase of a pair of turning levers respectively turnably attached by a prescribed phase with respect to both side walls of the holder main body in order to move the holder main body in the prescribed direction. CONSTITUTION:When a holder main body 1 is pressed down against an energizing force of a spring 12, an engaging pin 5L moves rightward along a long groove shape aperture 4L and an engaging pin 8H moves rightward along a long groove shape aperture 10L. Accordingly, a bottom surface of the cassette holder main body 1 is lowered substantially in a parallel condition to a chassis. The engaging pin 8L moves rightward along the long groove shape aperture 10L, thereby abutting against an end surface 16 of an engaging lever 13 to turn the engaging lever 13 clockwise. Further, the engaging pin 8L is fitted into an engaging groove 17 of the engaging lever 13, a lever 3L is positioned by the energizing force of the spring 12 and then the cassette holder main body 1 is positioned.</p> |
