Abstract

PURPOSE: To reduce a size of a copier and to raise its operation speed, by moving an original table and a light source in the direction reverse to each other in order to scan the original face.
CONSTITUTION: Original table 1 is moved in the direction of arrow R by 1/2 of the length of table 1 and at that time, light source 2, reflective plate 3, and reflective mirror 5b are moved in the direction of arrow S reverse to arrow R in synchronism to table 1 by the same length in order to scan the original. When table 1, source 2, etc. are moved at speed V to scan the original, and photosensitive drum 7 is rotated at a linear speed of 2V, an electrostatic latent image with the original size in the scanning direction is reproduced on drum 7.
