    • 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.
    • 光学写入装置包括光源,偏转和扫描光源的光偏转器,将光从光源引导到偏转器的预偏转光学系统,引导扫描的光束的偏转后光学系统 覆盖目标表面的光,覆盖偏转器的盖,并且包括设置在不同位置的第一开口和第二开口,以及容纳这些光学元件的壳体。 从光源行进到偏转器的光和由偏转器扫描的光被透过第一开口而不通过第二开口。 在偏转器的旋转期间,在第一开口中产生从外部流入外部的空气的强制流入,并且在第二开口中产生从内部流到外部的排出气流。
