摘要： A process camera includes a plurality of mandrels for supporting separate rolls of normally different film in continuous web form and is automatically controlled to thread a selected film web through the rear case of the camera, restrict the area of film to be exposed to a selected length, introduce and remove selected contact screens when needed, expose the restricted area selectively, advance the film, measure the amount of film web advanced, cut the film web between exposed areas at a location downstream of an optical axis of the camera to form cut sheets of exposed film and convey the cut sheets to a subsequent processing station at a speed compatible with the speed of operation of the processing station. Once an operator has programmed the necessary variable control parameters into the camera control means, the camera components are operated throughout one camera cycle in a predetermined series of steps following the program sequence without requiring further attention by the operator.

摘要： In graphic arts camera apparatus, a copyboard mounted on a frame for tiltable movement and having a cover section hinged to a base section and releasable latch for fastening the sections together is characterized by a latch actuator for automatically releasing the latch to permit separation of the hinged sections whenever the copyboard tilts from a vertical exposing position to a horizontal loading and unloading position. A catch mechanism prevents inadvertent release of the latch when the copyboard is vertically disposed, and the latch is biased toward a latched position to facilitate fastening the sections subsequent to loading the copyboard.

摘要： A pivoted holder for flat material such as a copyboard or similar device for use in a light exposure system is mounted on a support for tiltable movement selectively between an expose or process position and a loading position and includes elastic means interconnecting the copyboard and the support in a manner to urge the holder toward an equilibrium position approximately mid-way between the two extreme positions, thereby implementing actuation of the copyboard by an operator between selected positions.
