摘要	The present invention provides an optical scanning device capable of reliably and highly accurately positioning a detection means for generating a horizontal synchronization signal in an optical box, and forming images the image write start positions of which are stable. This optical scanning device is characterized in that a BD sensor (6) for detecting a write start position of a laser beam flux is secured to a control board (7) electrically connected to a semiconductor laser unit (1), the control board (7) is secured to an optical box housing a deflector provided with a rotary polygon mirror by securing screws (11a-11c), and the securing screw (11b) thereamong intersects at a right angle with a first straight line (C) connecting the semiconductor laser unit (1) and the BD sensor (6) and is disposed closer to the BD sensor (6) than a straight line passing above the semiconductor laser unit (1).
其他摘要	本发明提供一种光学扫描装置，其能够可靠且高度精确地定位用于在光学盒中产生水平同步信号的检测装置，并形成其图像写入开始位置稳定的图像。该光学扫描装置的特征在于，用于检测激光束的写入开始位置的BD传感器（6）被固定到电连接到半导体激光器单元（1）的控制板（7），控制板（7）通过紧固螺钉（11a-11c）固定到容纳具有旋转多面镜的偏转器的光学盒，并且紧固螺钉（11b）与连接半导体激光器的第一直线（C）以直角相交单元（1）和BD传感器（6），并且比经过半导体激光单元（1）上方的直线更靠近BD传感器（6）设置。
