<p>PURPOSE:To prevent any interference with a function part arranged on a base and to prevent a magnetic tape from flawing as well by lowering approximately vertically a cassette holder to be mounted on a cassette base in keeping its posture horizontal to the cassette base. CONSTITUTION:When a cassette 1 is inserted into the cassette holder 5, the cassette 1 is closely attached to a bottom surface of the cassette holder 5 by a pressing pad 5c. Then, when an auxiliary holder 6 is pressed down, the auxiliary holder 6 is turned around a supporting shaft 3a to turn a turning arm 12 via a cam roller 13 fitted into a guide groove 6f, so that a supporting shaft 12a for supporting the cassette holder 5 is also moved, but since a cam roller 14 embedded in the cassette holder 5 is also moved in a protruded circular- arcuate guide groove 6e of the turnable auxiliary holder 6, the cassette holder 5 is moved in keeping its horizontal posture. When the auxiliary holder 6 is further pressed down, the cassette holder 5 is moved in keeping its horizontal posture, so that the cassette 1 is situated on a positioning pin 2a and a height regulating pin 2b of a cassette base 2.</p> |
