Claims

[Scope of utility model registration request]

An information recording disk storage cartridge that includes a flat housing surrounding an information recording disk and a shutter unit that opens and closes an opening provided inside the flat housing, and that is attached to and detached from a performance mechanism along a predetermined direction. , the shutter unit has an opening/closing panel having a size that closes the opening and is biased by biasing means in a direction to maintain the closed position, and a side end portion of the flat housing parallel to the predetermined direction. a movable member that is slidably provided along the performance mechanism and that is movable by engaging with a locking member provided on the playing mechanism side; and a connection that has both ends coupled to the opening/closing panel and the movable member, respectively. and a locking member for locking the movable member to the housing, the locking member being configured to be released when the locking member engages with the movable member. Information recording disk storage cartridge.
