<p>PURPOSE: To eliminate mutual interferences of a guard panel and a front lid-opening member thereby to simplify and miniaturize an apparatus in structure, by opening/ closing the guard panel and the front lid-opening member integrally together. CONSTITUTION: When a cassette is loaded on a loading part 6 of a cassette receptacle 5, a tray 2 horizontally moves in a direction of an arrow A to start retreating, so that the cassette is taken inside because the height is changed by the shape of an upper end of a supporting arm 3 of a roller 21. The upper surface of the cassette is horizontally moved while being regulated by the roller 21 and a sliding part 19 of a retainer plate 18. In the vicinity of a terminal point, a first engaging part 93 of a first front lid-opening member 92 which is supported by a shaft 79 to a guard panel 90 is engaged with an engaging part of a first holding member 88. On the other hand, a second front lid-opening member 95 supported by the shaft 79 to the panel 90 is not engaged with a second holding member 89 because the second holding member 89 is turned and shifted to the center of a shaft 89a. A moving member 100 is also turned about a shaft 100a in association with the turning of the member 89 and moved in a widthwise direction of the cassette. As a result, the moving member 100 is not engaged with a cam arm 98 of the member 95, and the member 95 is accordingly not turned and shifted.</p> |
