Claims

[Scope of utility model registration request]

A disk drive device that records and reproduces information by introducing a disk cartridge containing a disk-shaped information recording medium into the device and rotationally driving the information recording medium, the disk drive device storing the disk-shaped information recording medium. A device comprising a transfer means for transferring the disc to the rotation means side of the disk, a holding means for holding the disk cartridge, and an engagement means capable of introducing the disk cartridge to the rotation means side of the disk along the holding means, The engaging means is formed by an engaging lever that can be engaged with the disk cartridge, and a slider that pivotably supports the engaging lever and is slidable along the inside of the side surface of the holding means. The engagement lever has a slope portion that faces and can make surface contact with a slope portion provided at one corner of the tip of the disk cartridge, and a slope portion of the disk cartridge and the engagement lever. a tip portion that engages from the side with the engagement groove of the disk cartridge when the inclined portions of the disk cartridge face and abut, and the tip portion engages with a portion of the side plate of the holding means when the cartridge is inserted. What is claimed is: 1. A disk drive device characterized by having a relief portion that can be locked to the disk and allows passage of a cartridge.
