Claims (1)

[Scope of utility model registration request] This is 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. In devices that perform automatic loading and ejecting, there is a load member that can reciprocate on the frame to transport the disk cartridge and is always energized toward the cartridge insertion side, and the position of the load member can be regulated during disk recording and playback. A lever member, a support means for supporting a gear group driven by the loading motor, and a final stage of the gear group mesh with each other, converting the rotation of the loading motor into linear reciprocating motion and transmitting the same to the loading member. a rack, a springing means for springing the lever member and the support means in opposing directions, and disengaging the engagement between the lever member and the load member, and the meshing between the gear group and the rack, respectively; A disk drive device comprising a manual change mechanism including an operation member capable of displacing the lever member and the support means in directions away from each other.
