Claims

[Claim for Utility Model Registration] A transfer means for transferring a disk cartridge between a loading position and an ejectable position, and a lock for preventing the disk cartridge from returning from an ejectable position to a loading position by the transfer means. means and
A slider that engages with the disk cartridge and indexes the disk cartridge in the ejectable position to the disk ejection port; The apparatus includes a spring member whose spacing can be expanded and contracted, and an eject drive means for driving the transfer means based on an eject signal, and the eject drive means drives the transfer means to transport the disk cartridge at the load position to a position where it can be ejected. Then, after preventing the disk cartridge from being returned by the locking means,
The rotary lever, which rotates in conjunction with the operation of the conveying means, is operated to apply a repulsive force to the spring member, and the repulsive force is used to index the disk cartridge to the disk ejection port via the slider. A disk drive device characterized by a curved shape.
