Abstract

Abstract A pickup aperture provided in a surface of a cartridge body, a sliding shutter provided with a bent portion to be locked by which this aperture is opened and closed, and a locking member provided with a locking recess with which the bent portion to be locked is engaged when the sliding shutter is in a cover-closing position, to thereby lock the shutter. An unlocking pin-inserting bore is provided in the portion of the sliding shutter which is closer to the free end thereof than to the locking recess. When the shutter is in a cover-closing position, an unlocking pin, which is provided on the portion of an apparatus which corresponds to the unlocking pin-inserting bore, is inserted therein, so that the locking member is displaced to cause the bent portion to be locked and the locking recess to be disengaged from each other, the shutter being thus unlocked. The shutter-unlocking operation is carried out with the locking member left fixed. Owing to the unlocking pin, by which this unlocking operation is carried out, the shutter is moved in both the pickup aperture-opening direction and pickup aperture-closing direction.
