PROBLEM TO BE SOLVED: To obtain a light scanning optical device capable of preventing deterioration of adjusting accuracy caused by a member that transmits motor rotation to an optical element. SOLUTION: The light scanning optical apparatus is mounted on a tandem type color printer of an electrophotography method. An imaging lens is held on a holder 52. A worm wheel 56 is engaged with a worm gear 55 that is fixed to the output shaft 51a of a motor 51, and an eccentric cam 57 is installed coaxially with the worm wheel 56. With the rotation of the eccentric circular cam 57, a receiving member 58 slides in the direction of an arrow F, the imaging lens is displaced via the holder 52, and the skew of the scanning line is adjusted. The bearing member 58 is resin-made and has excellent sliding property and durability, so that deterioration of adjusting accuracy is prevented. COPYRIGHT: (C)2008,JPO&INPIT
