Title:
OPTICAL SCANNING DEVICE AND IMAGE FORMING APPARATUS
Document Type and Number:
WIPO Patent Application WO/2018/092830
Kind Code:
A1
Abstract:
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).
