ABSTRACT:
A multi-beam laser scanning unit including a laser diode unit for discharging a plurality of laser beams, a rotational member for supporting the diode unit and rotating to a substantially aligned position between a plurality of the laser beams, a fixing member for supporting the rotational member in a rotatable manner, a temporary joining part for maintaining joining status between the rotational member and the fixing member in such a way that the rotational member easily rotates until position alignment between a plurality of the laser beams is achieved, and a fixing part for fixing the rotated rotational member to the fixing member.
