PURPOSE: To reduce the mounting of the cassette discharge motion of a kickout lever by reducing a spring energizing force after a certain specific term in a cassette discharging process.

CONSTITUTION: A cassette 1 is moved to a discharge direction by a cassette holder 5 and discharged from the cassette holder 5 by a kickout lever 3. After a certain specific term and on decided by the positional relation between the kickout lever 3 and cassette holder 5 at this time, i.e., after the cam abutting part 3a of the kickout lever 3 and a pressing cam 9 being not abutted, the rotation of the pressing cam 9 by the kickout lever 3 is released and the spring energizing force of the pressing spring 4 is reduced. The pressing force by a pressing roller 6 of the cassette 1 is reduced by this motion. The load of the cassette discharging motion of the kickout lever can be reduced.
