Abstract

PURPOSE: To enable the originals to be copied to be selected only through flashing of a lighting means by providing a half mirror on the common optical path formed by the original image optical paths from plural original modes.
CONSTITUTION: A thick original is placed on the original glass 2 of an original platen 3 and is made reciprocatively movable. At the time when it moves in the solid line direction of the arrow B, it is lighted by a lamp 4 and the light image is formed on the imaging part 10 on a photosensitive drum 1 by way of a mirror 5, half mirror 6, reflecting mirror 7, in-mirror lens 8 and reflecting mirror 9. On the other hand, the sheet-form orignals are placed on an original rest tray 26, are separated, sheet by sheet, by feed rollers 271, 272, are sent out toward a lighting part 28 and are lighted by a lamp 29. The original image is formed on the imaging part 10 of the photosensitive drum 1 by way of the half mirror 6, stationary mirror 7, in-mirror lens 8 and stationary mirror 9. Since the originals to be copied may be selected in this way without requiring the movement of the optical elements, the higher reliability may be assured for the formation of the original image.
