LASER DIODE MODULE OF LIGHT SCANNING DEVICE

摘要

PURPOSE: A laser diode module of light scanning device is provided to coordinate easily an optical axial distance between the collimator lens and the laser diode. CONSTITUTION: A laser diode module of light scanning device comprises a guider(100), a laser diode and a lens holder(300). The guider(100) has a barrel type guide side(110) formed inside of their center in back and forth direction and a flat guide side(120) formed in both sides around the barrel type guide side(110) and having an inserting hole(130) of the appointed diameter in backside. The laser diode is connected to the circuit board(400) and is inserted into the inserting hole of the guider(100). The lens holer(300) includes a cylinder body and a guide vane. The cylinder body is mounted to slide in back and forth direction along the barrel type guide side(110) of the guider(100) and is connected with the collimator lens capable of fixing the laser beam scanned from the laser diode in center side thereof. The guide vane is safely arrived to the flat guide side(120) extended from the both sides of the cylinder body.
