Abstract

PURPOSE:To make possible changing-over of three optical paths with one reflection member by providing an optical path which unmagnifies or reduces an original, an optical path which magnifies the same and an optical path which projects the same to a monitor screen. CONSTITUTION:When a drum 1 rotates up to a prescribed position, the original placed on an original platen glass 4 is lighted by a lighting lamp 6 which is constituted in one piece with the 1st scanning mirror 5 and the reflected light thereof is scanned by the 1st scanning mirror 5 and the 2nd scanning mirror 7. Next, in the case of a small original like a photographic film 32, the original 32 is transmitted by a lamp 29 with a reflection mirror and a condenser lens 30, and is macroprojected by way of a lens 33, the 5th mirror 34, the 6th mirror 35 and a mirror 9 for optical path changing. Further, in the case of observing the image of the film original 32 with a monitor screen 37, the image of the original 32 transmitted by the lamp 29 with reflection mirror and the condenser lens 30 goes through the lens 33, the 5th mirror 34 and the 6th mirror 35 and is macroprojected onto the monitor screen 37.
