    摘要: A housing includes a body having an opening. The body includes a peripheral portion that abuts on the opening. A cover covers at least a part of the opening. A seal is sandwiched between the cover and the peripheral portion of the body. At least one of the cover and the peripheral portion of the body includes a corner portion and a linear portion. The corner portion has a first shape that defines one of a gap between the cover and the peripheral portion of the body and a width of the seal. The linear portion abuts on the corner portion. The linear portion has a second shape that defines the one of the gap between the cover and the peripheral portion of the body and the width of the seal. The second shape is different from the first shape of the corner portion.

    摘要: An optical writing device includes a light source, an optical deflector that deflects and scans light from the light source, a pre-deflector optical system that guides the light from the light source to the deflector, a post-deflector optical system that guides the scanned light to a target surface, a cover covering the deflector and including a first opening and a second opening provided at different positions, and a housing housing these optical elements. Light traveling from the light source to the deflector and the light scanned by the deflector are transmitted through the first opening but not through the second opening. During the rotation of the deflector, a forced inflow of air flowing from outside to inside the cover is generated in the first opening, and a discharged airflow flowing from inside to outside the cover is generated in the second opening.

    摘要: An optical scanner includes a light source, an optical element, a deflector, a casing, and a first cover. The deflector deflects the light beam emitted from the light source to scan a photoreceptor through the optical element. The casing includes an upper opening, walls including a transparent plate defining a deflector compartment to accommodate the deflector, and an optical element mounting portion to accommodate the light source and the optical element. The first cover covers the upper opening of the casing and includes a recessed portion recessed toward the bottom of the casing and including a first opening at the bottom thereof facing the deflector. The recessed portion and the walls are directly or indirectly connected to define a single continuous space isolating the deflector compartment from the optical element mounting portion. The recessed portion and the deflector compartment communicate via the first opening.
