<p>PURPOSE:To simplify an opening/closing mechanism by opening a cassette cover with the moving operation of a cassette in the loading direction and closing the cover with the moving operation in the main plane direction at an ejection time. CONSTITUTION:A cassette cover 4 of the closed cassette inserted from a cassette insertion hole 17 in the main plane direction of the cassette reaches a position near contacting faces 20 and 21 of a cassette cover opening and cassette positioning member 19. In this state, a cassette holder 11 is depressed to load the cassette to a prescribed position. On the way of loading, the contacting face 21 collides against the lower edge of the cassette cover 4, and the cover 4 is turned clockwise and is opened. When the cassette is ejected, the cover 4 is raised in the open state. When the cassette is taken out in this state, the right edge of the cover 4 in the open state collides against a cassette cover closing colliding part 16, and the cover 4 is turned counterclockwise and is closed.</p> |
