OPTICAL SCANNER AND IMAGE FORMING APPARATUS

摘要

PROBLEM TO BE SOLVED: To improve dustproof performance and improve workability.SOLUTION: An optical box 49 comprises: a recessed notch part 105 that is formed by notching from the apex of an outer peripheral wall 49e of the optical box 49 in a direction toward the bottom part of the optical box 49; and a connection wall 83 that is bent and branched from the notch part 105 in the outer peripheral wall 49e in the internal direction of the optical box 49 so as to surround the notch part 105 and erects from the bottom part of the optical box 49. An upper cover 82 includes a sealing part 84 that is formed on the upper cover 82 to prevent dust from entering the inside of the optical box 49, the sealing part 84 being sandwiched between the upper cover 82 and the outer peripheral wall 49e, and between the upper cover 82 and the connection wall 83 through which an electric cable 80 connecting a deflector 41 and a circuit board passes when attached to the optical box 49; and the height of a tip part 83a of the connection wall 83 through which the electric cable 80 passes from the bottom part of the optical box 49 is higher than the height of the recessed bottom part 105d of the notch part 105 from the bottom part of the optical box 49.SELECTED DRAWING: Figure 4
