Claims

[Scope of Claim for Utility Model Registration] (1) A disk cartridge in which a disk-shaped recording medium is rotatably housed in a cartridge case, the disk cartridge being housed in a predetermined portion of the cartridge case. In the cartridge case, a plurality of sensor holes are provided at predetermined positions of the cartridge case, and a plurality of sensor holes are provided at predetermined positions of the cartridge case. A sensor hole that is closed to display the driving conditions of the disk-shaped recording medium stored in the disk cartridge case is selectively connected to the sensor hole by a closing piece formed separately from the cartridge case. A disc cartridge characterized by being closed. (2) Sensor holes of the same shape and size are formed in opposing positions of the upper case and lower case that constitute the cartridge case, and a closing piece formed vertically symmetrically is selectively fitted into the sensor hole. A disk cartridge according to claim 1 of the utility model registration claim, characterized in that: (3) Sensor holes are provided at opposing positions in the upper and lower cases, and retaining ridges into which a closing piece can be inserted are provided around the sensor holes on the inner surfaces of the upper and lower cases. A disk cartridge according to claim 1 of the patented utility model.
