ABSTRACT:
Apparatus for holding a master microfiche in contact with a copy sheet of film in a machine that includes rollers for moving the copy sheet onto the master and then off of it towards a developing station. The holder includes a base or lower frame containing a glass plate, and an upper frame that can move away from the lower frame to enable the insertion of the master between the upper frame and the glass plate. The upper frame includes thin rollers rotatably mounted about a vertical axis and having peripheral portions lying over the edge of a master on the lower frame. A transport roller for feeding a copy film onto the master, can bear against the periphery of the thin roller, so that the copy film is captured between the two rollers to facilitate its movement. The frame can be lifted by pivoting down a handle at one side of the holder, which slides a pair of rods with camming portions that move against the upper frame to lift it.
