Claims

[Claim for Utility Model Registration] A laser continuously formed extending from the outer periphery to the center on the side facing the disk signal surface of a cartridge in which a compact disk is housed so that it can rotate when the player is set.・The compact disc cartridge has a notch that serves as a passage for the beam, and this notch can be opened and closed with a locking mechanism on the lid body of the compact disc cartridge. A shutter plate having the same or similar shape to the notch is provided, a pressing member for pressing the shutter plate toward one side of the cartridge to close the notch is attached to the shutter plate, and a pressing member is attached to the shutter plate directly to the shutter plate. Alternatively, an engaged portion may be provided which is indirectly engaged with an engaging portion provided on the player, and the shutter may be moved when the cartridge is inserted into the player while the engaging portion and the engaged portion are engaged. A lid locking mechanism for a compact disk cartridge is characterized in that the plate is rotated against the pressing force of a pressing member to open a notch, and the lid of the cartridge has one hook-shaped protrusion. A locking mechanism for a lid body of a compact disk cartridge, characterized in that a locking plate made of an elastic member is fixed to the cartridge body so as to be engageable with the hook-shaped protrusion.
