Claims

[Scope of utility model registration request]

In a disk drive device in which a disk cartridge containing a disk-shaped information recording medium is introduced into the device and the information recording medium is rotationally driven to record and reproduce information, a disk that can reciprocate on a frame is used. A load member for transporting the cartridge, and a frame that protrudes from the side where the load member is not provided to the side where the load member is provided and engages with a portion of the load member at a predetermined position to form the frame. A lever member capable of regulating the position of the load member at the top and an engagement groove in which the load member is movably engaged are formed, and the load member can be moved in the loading direction and the ejection direction by the loading motor. and a rack that, when the loading motor rotates in the ejection direction, comes into contact with a part of the lever member and pushes the lever member down toward the non-load member disposed side of the frame, thereby releasing the restriction on the position of the load member. A disk drive device characterized by:
