Claims

[Claims for Utility Model Registration] Window portions are formed on both the upper and lower surfaces of the disk for housing a disk on which information signals are written and allowing the signal recording surface formed on the main surface of the disk to be viewed outward in the radial direction. a shutter member formed by connecting one end side of a pair of upper and lower shutter plates that close each window of the cartridge with a connecting plate; and a shutter member that is slidably supported by the cartridge and to which the shutter member is attached. and a countersunk screw for screwing a connecting plate of the shutter member to one side of the slide member, and a screw insertion hole in the connecting plate of the shutter member having a diameter larger than the head diameter of the flat screw. At the same time, on the inner circumferential side of the screw insertion hole, a retaining regulating piece is bent and inclined toward the inner side of the shutter member, and a part of the slide member facing the connecting plate of the shutter member is bent. A countersunk screw head fitting recess is provided on the side surface, and a screw screw position regulating part is provided in the head fitting recess, and the shaft portion is inserted into the screw insertion hole to be screwed onto the slide member. The head of the screw abuts against the screw screw insertion position regulating portion to restrict the screw insertion position, so that the connection plate of the shutter member is supported by the slide member in a non-pressurized state, and the A disk cartridge supported by a retaining regulating piece to prevent it from coming off from the countersunk screw.
