Abstract
A disk cartridge opposite-insertion preventing mechanism has levers 11 pivoted on shafts 12 in opposite sides of a carrying tray 10 into which a disk cartridge 1 is inserted. Torsion springs 13 are provided for urging the levers to project into the carrying tray; and projections 14 are formed at respective forward ends of the levers so as to be bent inward to permit the projections 14 to engage with terraced grooves 2 provided in opposite sides of a forward end portion of the disk cartridge 1. In this manner the insertion of the disk cartridge is prevented by the engagement between the projections and the grooves when the disk cartridge is inserted in a direction opposite to normal.
