ABSTRACT:
An auto-process camera which permits unloading, and subsequent reloading, of a cassette containing film monosheets, without the monosheets being exposed. When a cassette is initially loaded in the camera, a light-proof protective board, which protects the monosheets therein prior to use thereof, is removed via an extraction passage leading to the camera exterior, the extraction passage being also employed for removal of exposed monosheet. If it is required to unload the cassette while there are still unexposed monosheets therein, the protective board is re-inserted into the camera, either through the extraction passage, or through another passage provided specifically for re-insertion of the board, push elements are actuated to move the contents of the cassette slightly rearwards, to permit unhindered entry of the board into the cassette, and the board is then moved into its original position in the cassette, after which the cassette may be unloaded, the monosheets therein remaining unexposed, and available for subsequent use. Actuation of the push elements and re-insertion of the protective board may be effected manually, or by automatically actuated electronic control device.
