Abstract: PROBLEM TO BE SOLVED: To provide an optical scanning device capable of adjusting a position of a scanning line with high accuracy while applying triangular and/or trapezoidal spur gear and crown gear which have simple teeth shapes.SOLUTION: When a pinion gear 125 rotates once, a crown gear 123 rotates by one tooth, a screw 122 moves only by 9.6 μm in a sub-scanning direction X, one end 109a of a second fθ lens 109 moves only by 9.6 μm in the sub-scanning direction X, and accordingly a movement distance of a main scanning line on a photosensitive drum 13 corresponding to one rotation of the pinion gear 125 is 9.6 μm or less. Therefore, even when there exists backlash between the pinion gear 125 and the crown gear 123, a position of the main scanning line can be adjusted and set with such a high accuracy as to be 10.5 μm (dot half) or less.

Abstract: PROBLEM TO BE SOLVED: To maintain the precision of position control of a carriage without being influenced by an external force such as a driving force from a motor for moving the carriage at the time of position control of the carriage, by using a timing fence for expanding/contracting a range parallel to a movement direction of the carriage in accordance with the expansion/contraction of right and left enclosure parts for the position control of the carriage.
SOLUTION: Each end of the timing fence 43 having a continuous pattern is fixed to one end of an elastic member 48 set at each of the right and left enclosure parts 2 and 3. The timing fence 43 is constructed with the use of rollers 49 and 50 supported by roller supporting parts 51 and 52 arranged at the right and left enclosure parts 2 and 3, respectively. At the time of expansion of the right and left enclosure parts 2 and 3, an elastic force acts on the elastic members 48 in an arrow Y direction as a main scanning direction and expand in the arrow Y direction. At this time, the timing fence 43 is expanded by an amount of the expansion of the elastic members 48.
