<p>PROBLEM TO BE SOLVED: To provide a multibeam light deflecting scanner having a satisfactory assemblability where rotation of a multiple light source unit is easily adjusted and the extent of adjustment is not changed before and after fixing at the time of screw fixing after rotation adjustment. SOLUTION: In this multibeam light deflecting scanner, a multibeam light source unit is provided where a light beam light source which emits plural laser luminous fluxes is driven and controlled by a circuit board 7 and is held by a laser holder 5, and the multibeam light source unit is fixed to an optical box 8, and plural laser luminous fluxes from the light source are deflected by a rotary polygon mirror. The laser holder 5 has a grip for rotation adjustment like a projecting or recessed part; and when the multibeam light source unit is fixed to the optical box 8 by screws, the multibeam light source unit is rotated with the grip part in a hand to adjust the intervals of plural laser luminous fluxes to prescribed intervals.</p> |
