<p>PROBLEM TO BE SOLVED: To simplify the structure and to interrupt entering of dust by providing an inside door opening only at a caddy take-out time and an outside door hinge fixed to it and opening in the one direction only at an insertion time. SOLUTION: When the caddy 10 is pushed into the port of the outside door 12, the inside door 13 turns around a pin 13b to open inside. At this time, since the upper end part of the outside door 12 is prevented by a cover 11, the door 12 isn't pressed in the insertion direction of the caddy, and only the inside door 13 is opened. Succedingly, when the caddy 10 is ended to be inserted, the inside door 13 is closed by force of a torsion spring. When the caddy 10 is taken out, the caddy 10 is transferred to the door, and when the caddy 10 presses the inside door 13 by the transfer force, the inside door 13 presses the outside door 12, and the outside door 12 turns around a hinge position to open in the take-out direction. When the caddy 10 is taken out, the outside door 13 is closed by the force of the torsion spring 14 of the pin 13a of the inside door 13. Thus, the structure is simplified, and the entering of dust is interrupted, and the life of a driver is prolonged, and the reliability is improved.</p> |
