Abstract: PURPOSE:To prevent the adverse loading of a disk cartridge by providing a lever having a projection part engaging a stepped groove on a device or a case main body by means of the groove formed on the side face of the tip part of the cartridge. CONSTITUTION:The sections of a transfer tray 10 has an almost recessed shape, and a lever 11 is attached via a shaft 12 at the middle part between both sides of the tray 10. The shaft 12 is provided with a twist spring 13 which energizes the lever 11 to erect at the inside of the tray 10. The tip of the lever 11 bends toward the center of the tray 10 to form a projection part 14. The lever 11 protrudes at the inside of the tray 10 through an opening part 15. If a disk cartridge is adversely loaded, the part 14 of the lever 11 gets into a groove 2 and is pushed by a rear level difference part 2a of the groove 2 when the cartridge is pushed further. Thus the lever 11 tries to turn toward B around the shaft 12. Then the loading of the cartridge is impossible since the part 14 cannot get out of the groove 2 owing to the part 2a of the groove 2.
