ABSTRACT:
A first and second rotary members are supported on a holder 3 secured to a main chassis of disk drive apparatus. The first rotary member includes a detecting portion. The second rotary member includes a contact portion that moves in and out of the insertion path of a disk cartridge to be inserted into the holder. When the disk cartridge is being inserted, an opening-and-closing pin opens the shutter of the disk. Through the detecting portion, the opening shutter rotates the first rotary member, which then rotates the second rotary member to thereby move the contact portion of the second rotary member out of the insertion path of the disk cartridge, allowing the disk cartridge to be inserted. If the shutter fails to open when the disk cartridge is being inserted, the contact portion of the second rotary member will remain in the insertion path and block the insertion of the disk cartridge.
