Claims

[Scope of Claim for Utility Model Registration] (1) A plate-shaped shutter that opens and closes the window by sliding linearly in contact with the window formed in the box body of the disk cartridge; A rotary member that is pushed and rotated by the rod of the disk drive device when attached to the drive device, a coupling mechanism that converts the rotation of the rotary member into sliding motion of the shutter, and a coupling mechanism that biases the shutter in one direction. In the shutter slide mechanism of a disk cartridge equipped with a torsion spring for the rotation of the rotating member, a shaft hole is formed at the center of rotation of the rotating member, and a torsion spring is fitted and inserted into the outer periphery of the rotating member. ,
A shutter slide mechanism for a disc cartridge, characterized in that the box body of the disc cartridge is provided with a pivot shaft that fits into the shaft hole that rotatably holds the rotating member. (2) The shaft of a disk cartridge according to claim 1, wherein the coupling mechanism is comprised of a pinion gear fixed to the rotating member and a rack gear fixed to the shutter. Tarslide mechanism.
