PURPOSE:To prevent a malfunction which is caused when a cassette is ejected by securing such a constitution where the cassette is ejected by pushing an ejection plate after a lock projection of the ejection plate is engaged with its engaging part when the cassette is ejected. CONSTITUTION:When a cassette 2 is ejected, a button 4 of an ejection plate 3 is pushed. Thus a rotary part 6 of a cassette holder 5 is held up along a sloping part 7, and a lock projection 8 is engaged with its engaging part 10 when the part 6 is gone up to a horizontal part 11. Under such conditions, a detention part 47 of a cassette pop-out preventing plate 33 set on the upper surface of the holder 5 is still engaged with a positioning hole 32. Thus the cassette 2 is never ejected. When the button 4 is pushed more after the projection 8 is engaged with the part 10 of a lock device 9, the engagement is released between the detention part 47 and the hole 32. Thus the cassette 2 can be ejected toward an arrow head along the holder 5. |
