ABSTRACT:
A camera accessory to receive a cartridge of photosensitive material and direct the said photosensitive material into a camera. A light-tight enclosure having a door therein permits the cartridge to be introduced into the interior of the accessory. The cartridge is provided with a hollow core upon which the photosensitive material is wound. A light-tight bag of plastic material overlies the photosensitive material. After the cartridge is placed within the enclosure and the door closed, an elongated plunger operable from without the enclosure and extending through the door urges the bag into the hollow core thereby uncovering the photosensitive materials for subsequent feeding into a camera.
