き込み禁止機構。 In a write-inhibiting mechanism for a disk cartridge in which a disk serving as a recording medium is rotatably stored in a cartridge in which upper and lower halves are overlapped, and a portion of the cartridge is provided to prevent double writing on the disk. The mechanism consists of a movable plug that can be moved from the outside of the cartridge, and a housing that movably stores this movable plug. a locking leg that projects in the longitudinal direction of the main body from one end in the vertical direction of the main body; and a locking leg that is formed on a peripheral inner surface surrounding the storage section and moves in cooperation with the locking leg. The protrusions projecting upward and downward of the main body are provided with respective openings formed on the upper and lower halves of the cartridge into which detection pins on the recording/reproducing device side are inserted or through which light beams from optical sensors pass. of the disk cartridge, wherein one of the protrusions is formed with a moving member insertion hole into which a moving member such as a pin for moving the movable plug from the outside of the cartridge is inserted. Write protection mechanism.
