Claims (1)

[Scope of utility model registration request] A case body formed by combining two upper and lower case halves, a magnetic head insertion window formed in the disk setting area of this case body, and a magnetic head insert rotatably supported within the case body. A shutter member for opening and closing a window, a flexible slider that rotationally displaces the shutter member from the open position to the closed position in response to setting and resetting operations on the recording/reproducing device, and a flexible slider for rotationally displacing the shutter member from the open position to the closed position. It has an arc-shaped curved part that corresponds to the rotation range up to
and a sliding groove for guiding a slider whose front end in the closing direction extends further forward in the closing direction than the closed position of the shutter member, and a sliding groove located outside the curved part of the sliding groove so that the slider A stopper wall for stopping the shutter member being moved to the closed position; and a stopper wall that protrudes from the inner wall of at least the lower case of both the upper and lower cases, abuts against the upper case side, and that substantially extends from the setting area of the disk. and a surrounding bulkhead;
The height of at least the portion of the partition wall of the lower case from the position corresponding to the stator flange wall to the position corresponding to the front end of the curved part is set to 1 of the distance between the inner walls of both the upper and lower cases.
A disk cartridge whose length exceeds 72 mm.
