Abstract

Abstract A two-part replaceable cassette-like device is provided, having a disposable cassette portion and a light sealed buffer box, having a pair of drive rollers therein and which is detachably fastened to the disposable cassette, whereby the photosensitive material driven out of the cassette will be driven through the light sealed buffer box into a camera processor. Upon exhaustion of the photosensitive media within the cassette, the buffer box is removed from the cassette for reuse and the cassette is thrown away. A gear coupled to the buffer box roller material drive means is automatically rotated during insertion and withdrawal of the buffer box to and from the camera due to roller contact with a stationary drive gear positioned within such camera.
