摘要： A disk apparatus includes a chassis outer sheath with a base body and a lid. A slider mechanism is disposed on one end of a traverse, the slider mechanism includes a vertically moving cam mechanism which brings the traverse close to and away from the base body. A cam groove of the vertically moving cam mechanism has a first cam portion which moves together with the slider mechanism and a second cam portion which is displaced with respect to the first cam portion. When a vertically moving pin of the vertically moving cam mechanism exceeds a predetermined height in the cam groove, the second cam portion rises and the second cam portion limits movement of the vertically moving pin. When the vertically moving pin is equal to or lower than the predetermined height in the cam groove, the second cam portion is held at its lowered position.

摘要： It is an object of the present invention to provide a disk apparatus in which the driving mechanisms for the pulling-in lever and the discharging lever can be accommodated in limited spaces and the disk can be prevented from being damaged when the disk apparatus is abnormally operated.A base body 10 includes a pulling-in lever 80 which inserts a disk, a discharging lever 100 which discharges the disk, and a slider mechanism which turns the pulling-in lever 80 and the discharging lever 100. The slider mechanism includes a first cam groove in which a first pin of the pulling-in lever 80 slides, and a second cam groove in which a second pin of the discharging lever 100 slides. When the slider mechanism is operated, the first pin slides in the first cam groove, thereby turning the pulling-in lever 80. When the slider mechanism is operated, the second pin slides in the second cam groove, thereby turning the discharging lever 100. The slider mechanism includes a resilient member 44 which expands and contracts in a sliding direction of the slider mechanism, a first movable piece 45 provided on one end of the resilient member 44, and a second movable piece 46 provided on the other end of the resilient member 44. The first pin displaces the first movable piece 45 by a load applied to the pulling-in lever 80 from the disk. The second pin displaces the second movable piece 46 by a load applied to the discharging lever 100 from the disk.
