Abstract
A process camera includes: an original holder; a lens for projecting an image of the original on an image forming plane; a frame having an opening defining the image forming plane; a focusing glass attached to the frame movable between a portion covering only a part of the opening of the frame and an open position freeing the opening for forming an image of the original of the surface thereof; a vacuum board for holding a film thereon; and a member for mounting to the frame the vacuum board rotatably around a predetermined axis of rotation between a closed position covering all of the opening and a position covering only a part of the opening. Since the area of the focusing glass is selected to be smaller than the area of the opening, the area required by the focusing glass at the open position is small. The axis of rotation of the vacuum board is provided crossing the opening, but not along sides of the opening. The axis of rotation of the vacuum board is provided at a position other than an end portion of the vacuum board.
