    Abstract: An optical scanning apparatus includes a plate member, having a rotation axis and a reflection surface, that deflects and scans a laser beam emitted from a light source by performing reciprocating-rotation around the rotation axis, an actuator configured to drive the plate member, an fθ-lens configured to focus the laser beam deflected by the plate member on a surface of a photosensitive drum, and an optical box configured to house the plate member, the actuator, and the fθ-lens. The actuator is provided nearer to a side of the optical box toward which the laser beam is reflected by the reflection surface than the reflection surface of the plate member is.

    Abstract: A deflector deflects a light beam from a light source. A scanning optical system focuses the light beam deflected by the deflector. An image carrying member is located at a focal position of the light beam and includes a surface that is scanned in a main scanning direction with the light beam focused by the scanning optical system. One pixel of an image is formed by a plurality of light spots having different focal positions in at least a sub-scanning direction. At least one light spot from among the light spots is formed on the surface of the image carrying member at a scan timing different from those of rest of the light spots.

    Abstract: A scanning module capable of finely tuning the optical length comprises a lamp tube, a base, a photosensitive substrate, and an adjustment unit. The lamp tube provides a required light source for a document to be scanned. The base has a reflective mirror set and a camera lens. The reflective mirror set is used to receive light from the document, and transmits the light to the camera lens for focusing. The photosensitive substrate is used to convert light outputted by the camera lens into electronic signals. The adjustment unit is used to adjust the optical length between the base and the photosensitive substrate. The total optical length can thus be adjusted to correct the inaccuracy of magnification. Or the distance between the camera lens and the photosensitive substrate can be adjusted to align the focal length within the allowable inaccuracy of magnification to achieve an output image of better quality.

    Abstract translation: 能够微调光学长度的扫描模块包括灯管，基座，感光基片和调节单元。 灯管为要扫描的文件提供所需的光源。 底座有反光镜组和相机镜头。 反射镜组用于从文件接收光，并将光传输到相机镜头进行聚焦。 感光基板用于将照相机镜头输出的光转换为电子信号。 调整单元用于调节基底和感光基片之间的光学长度。 因此可以调整总光学长度以校正放大率的不精确性。 或者可以调节相机镜头和感光基片之间的距离，以使焦距在允许的放大倍率不准确之内，以实现更好质量的输出图像。
