The camera is a Goodkin vertical process 18-inch unit
equipped with an 8.25 in. focal length wide- angle color
accomplished by adjustment of the calibration tapes for
the lens and copyboard. Two vacuum pumps are
provided with the camera. The pump to the right of the
camera, controlled by a foot pedal, is connected by
means of a flexible hose to the under- side of the
copyboard. During operation this pump provides the
vacuum for even contact for the material to be
reproduced. The pump to the left of the camera,
controlled by the camera power switch, is connected by
means of a flexible hose to the film case and provides
vacuum for even contact of the film during exposure.
Camera lighting is supplied by four 650 watt quartz
lamps located in two housings, bracket mounted, one on
each side of the copy-board base. A one-piece conical
bellows serves as a light-tight seal between the lens
case and the film case. Camera controls and timer are
located in a control panel installed on top of the
equipment. The camera lens is removed and placed on
a bracket in the inverted position during camera moving.
Never leave lens bellows extended
when the camera is not in use.
Retract bellows so as to maintain
folds in correct position.
Removal. Remove the process camera as
connector from the wall receptacle.
Disconnect the vacuum hoses from the
film holder and copyboard adapters.
