Claims

[Scope of utility model registration request]

a cartridge case consisting of an upper case and a lower case and having window holes on both sides for inserting a spindle and a head; a disk-shaped recording medium rotatably housed inside the cartridge case; In a disk cartridge comprising a slider slidably attached along the front edge of a cartridge case, and a shutter that slides together with the slider to open and close the window hole, when the shutter of the slider is opened and A recessed portion for engaging the first shutter opening arm is provided near the rear end, and a slope for engaging the second shutter opening arm is formed at the front end, and the slope corresponds to the recessed portion of the shutter. A disk cartridge characterized in that a notch is formed at a position that allows the inner surface of the concave portion to be exposed to the outside, and a notch that allows the slope to be exposed to the outside is formed at a position corresponding to the slope.
