Abstract

PURPOSE: To make possible high-speed scanning with a simple constitution by moving a plane mirror as specified according to the original scanning radiation of a lighting device.
CONSTITUTION: A lighting device 3 moves parallel to an original 1 by which the original 1 is scanned and radiated. The reflected light from the original 1 expose a photosensitive drum 2 through an imaging lens 4 and plane mirror 5. If the movement of the mirror 5 along with the movement of the device 3 is so controlled that the mirror positions on the perpendicular bisector of the straight lines A'L, B'L... connecting the imaginary imaging points A', B' by this lens 4 and the exposure point L of the drum 2, then the exposure imaging point becomes the specified fixed point, thus the high-speed scanning may be done by the simple constitution of not requiring the movement of the imaging lens of a relatively large weight.
