Abstract
PURPOSE: To enable multiple exposure to be done by providing a half mirror within a part of the through-lens on the common optical path formed by the original image optical paths from plural original modes.
CONSTITUTION: The originals are placed on original platen glasses 21, 22. The one original is reflected from a lighting lamp 31 via moving scanning mirrors 41, 51 by the half mirror 7 provided in the central part of a through-lens 6 and is further reflected by a stationary mirror 8, thus its image is formed on a photosensitive drum 1. The other original is reflected from lighting lamp 32 via moving scanning mirrors 42, 52 by a stationary mirror 9, transmits through the half mirror 7 provided in the through-lens 6, is reflected by the stationary mirror 8, thus its image is formed on the photosensitive drum 1. In this way, the respective light images from the plural originals are independently formed and the original to be copied may be selected through flashing of the lighting lamps 31, 32 without moving any optical element.
