<P>PROBLEM TO BE SOLVED: To provide an optical scanning device that is capable of adjusting curving of a scanning line from both surface sides of an optical element, allows the optical element to be easily inserted between supporting members, and is capable of fixing a position the optical element in a direction of a short side thereof. <P>SOLUTION: An eccentric cam 391 is selectively arranged opposite to either one of surfaces of a third fθ lens 390 so as to press the opposing surface of the lens 390. Mounting sections 392A and 392B for mounting the eccentric cam 391 are arranged on both sides of the third fθ lens 390 while facing the longitudinal surfaces of the third fθ lens 390. First supporting members 393A and 393B are configured to restrict movement of the third fθ lens 390 with the pressing force from the eccentric cam 391. Second supporting members 394A and 394B are arranged on the opposite side of the first supporting members 393A and 393B across the third fθ lens 390 so as to restrict movement of the third fθ lens 390 with the pressing force from the eccentric cam 391. <P>COPYRIGHT: (C)2012,JPO&INPIT |
