    • In a scanner housing of an optical scanner fixed to a main body housing of an image forming apparatus, an opposite wall is disposed between a support wall on which an optical element is supported and a wall of the main body housing. A space at an extreme end of an inner projection has a distance smaller than distances at all other spaces between the support wall and the opposite wall. A space at an extreme end of an outer projection has a distance smaller than distances at all other spaces between the wall of the main body housing and the opposite wall. The space at the extreme end of the inner projection overlaps with the space at the extreme end of the outer projection as viewed from a direction in which the inner projection and the outer projection project.
    • 在固定在图像形成装置的主体壳体上的光学扫描器的扫描器壳体中,相对的壁设置在支撑有光学元件的支撑壁和主体壳体的壁之间。 在内部突起的最末端处的空间的距离小于支撑壁和相对壁之间的所有其它空间处的距离。 在外部突出部的最末端处的空间的距离小于主体壳体的壁与相对的壁之间的所有其它空间处的距离。 从内投影和外投影的方向观察,内投影的最末端处的空间与外投影的最末端处的空间重叠。

    • An optical scanner includes: a light source; a light deflector configured to deflect a light beam from the light source in a main scanning direction; a scanning lens through which the light beam having been deflected by the light deflector passes; a beam detector configured to detect the light beam; a mirror disposed between the light deflector and the scanning lens in an optical axis direction of the scanning lens and configured to reflect the light beam having been deflected by the light deflector toward the beam detector; and a wall portion configured to cover one end face of the mirror that faces the scanning lens, wherein the surface of the wall portion facing the scanning lens is tilted with respect to a sub-scanning direction orthogonal to the main scanning direction.
    • 光学扫描器包括:光源; 光偏转器,其构造成在主扫描方向上偏转来自所述光源的光束; 已经被光偏转器偏转的光束通过的扫描透镜; 光束检测器,被配置为检测光束; 镜子,其设置在所述光偏转器和所述扫描透镜之间的所述扫描透镜的光轴方向上,并被配置为将由所述光偏转器偏转的光束反射到所述光束检测器; 以及壁部,被配置为覆盖面向扫描透镜的反射镜的一个端面,其中面向扫描透镜的壁部的表面相对于与主扫描方向正交的副扫描方向倾斜。
