发明名称 Light shielding magazine for a film cartridge
摘要 A light shielding magazine includes a pair of holders pivotable relative to each other for receiving a film cartridge. The film cartridge includes a film feed opening and a pivotable light shield provided for the film feed opening to prevent entry of ambient light and to allow passage of a film through the film feed opening. One of the holders defines a cover portion for covering the film feed opening when the light shielding magazine is mounted on the film cartridge, to prevent entry of ambient light to the film feed opening and to allow passage of the film fed out through the film feed opening.
