Abstract: A graphic camera/platemaker optical system is described having a copyboard for an original subject, a lens, an image plane and a mirror. The copyboard, lens and mirror are independently movable such that they may move in different directions in order to produce a variable scale image or reproduction of the original onto the image plane. The movable elements are positioned by separate stepping drives controlled by a common microprocessor.

Abstract: The disclosure is directed to an extremely compact camera-processor which is configured to sharply reverse the direction of the exposed light sensitive sheet as it leaves the exposure plane. The light sensitive sheet is thereafter driven downwardly into a processor bath along with a relatively flimsy receptor sheet.

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.

Abstract: A pivotable camera back is provided containing a film cartridge having a movable light sealing member for preventing light from entering the cartridge when the camera back housing is pivoted to an open position for access thereto, together with a sealing member actuation device for causing the light sealing member to open with respect to the cartridge feed orifice to permit photosensitive material to be fed to the imaging area upon the closing of the camera back housing.
