PROBLEM TO BE SOLVED: To easily draw out a tray with a simple and inexpensive structure when the electricity is shut off. SOLUTION: The drawer mechanism 8 for drawing out the tray 2 forcibly from the opening 3 of a casing 1 when the electricity is shut off has a forced ejection button 10 which can be drawn in the casing 1 and is arranged movable in lateral directions (c) and (d) orthogonal to ejecting directions (a) and (b), and is inserted into a ejection hole 9 passing through the casing 1 when the drawer mechanism 8 is projected. The button 10 is retracted in the casing 1 when the electricity is turned on, and projected from the ejection hole 9 when the electricity is shut off. A button operation mechanism 11 is provided to move the button 10 in the lateral direction (c) and thereby to engage the button 10 with the tray 2. The tray 2 is forcibly drawn out from the opening 3 of the casing 1 by pushing the button 10 projected from the ejection hole 9. COPYRIGHT: (C)2004,JPO
