Claims (1)

[Claims for Utility Model Registration] In a disk drive device that records or reproduces information, or records and reproduces information by introducing an information recording medium formed in a disk shape, a projection is provided on the side surface and the information recording medium is A holder to be held in the device, a groove horizontal to the bottom plate into which the protrusion is inserted into a side plate formed into a substantially U-shaped cross section and rising perpendicular to the bottom plate, and an anti-disc car in this horizontal groove. A frame body having a substantially L-shaped guide groove formed by a vertical groove part hanging from the end on the tray insertion side to the bottom plate, and an inclined groove part connecting the horizontal groove part and the vertical groove part; , The protrusion is moved along the horizontal groove of the frame on a side plate that is supported by the frame so as to be slidable in the insertion/ejection direction of the information recording medium and moves adjacent to the side plate of the frame. A groove formed perpendicularly to the bottom plate, a groove inclined to the bottom plate for moving the protrusion along the vertical groove of the frame, and a position of the protrusion closest to the bottom plate are defined. a slide plate having a cam groove formed from a groove section horizontal to the bottom plate; a biasing means for always biasing the slide plate in the direction of insertion of the information recording medium; and a biasing force of the biasing means for the slide plate. a locking means for holding the information recording medium at a preset standby/ejection position against the pressure, and a locking means for releasing the holding state of the slide plate of the locking means when the information recording medium is inserted to the preset position. A disk drive device comprising: a release means;
