光扫描装置的制造方法、光扫描装置和图像形成装置
Abstract:
本发明提供光扫描装置的制造方法、光扫描装置以及具备该光扫描装置的图像形成装置，即使光扫描装置中的合成树脂的支承件随时间推移而收缩时，也能够将所述光扫描装置输出的激光的焦点位置的变化抑制到极小。将半导体激光元件的前面作为头部，半导体激光元件的凸缘部从纵壁部的第一面侧被压入到纵壁部的通孔的外接孔部。外接孔部是与所述凸缘部的外周面相接触的部分。在所述凸缘部被压入所述外接孔部之前或者之后，准直透镜安装到支承件上。所述凸缘部向所述外接孔部的压入，在所述凸缘部的所述半导体激光元件的前面侧的边缘部留在所述外接孔部内的位置停止。所述准直透镜在所述半导体激光元件的正面方向的出射光的路线上，安装在所述支承件上。
Abstract(English):

A flange portion(522) of this semiconductor laser element(52) is press-fitted, with a front face of the semiconductor laser element(52) serving as the leading head, into an externally-contacting hole portion(511x) of a through-hole(5110) in a vertical wall portion(511) from a first face side of the vertical wall portion(511). The externally-contacting hole portion(511x) is to be in contact with an outer peripheral surface of the flange portion(522). A collimator lens(54) is mounted to a support body(51) before or after the flange portion(522) is press-fitted into the externally-contacting hole portion(511x). The press-fitting of the flange portion(522) into the externally-contacting hole portion(511x) is stopped at a position where an edge portion, of the flange portion(522), on the front face side of the semiconductor laser element(52) rests within the externally-contacting hole portion(511x). The collimator lens(54) is mounted to the support body(51) in a path of emitted light in front of the semiconductor laser element(52).
