MULTI-BEAM LIGHT SOURCE UNIT AND, LASER SCANNING UNIT HAVING THE SAME AND METHOD FOR ASSEMBLING THE LASER SCANNING UNIT

摘要

The Multi plurality of laser alignment bimgan to increase work efficiency and productivity by easily assembling yirueojim - discloses a laser beam scanning unit. The invention disclosed diode unit comprising a laser diode for emitting a plurality of laser beams; Supporting the diode unit rotates the rotatable member; A fixing member for supporting the rotary member rotatably, and; The light source unit comprises a beam-rotation member includes a plurality of laser bimgan rotational position is aligned with the rotational angle is selected to a fixed member fixed to the Multi. According to this, the multi-position after the sort operation in a plurality of laser beam light source unit bimgan assembly line, on the main assembly line, a multi-beam light source unit to be mounted simply on the frame to complete the assembly of the laser scanning unit. Therefore, it is not necessary to provide such a large laser beam alignment jig as in the prior art on the main assembly line there, it is possible to reduce the structural simplification and size reduction of the main assembly line, while facilitating the laser can be accurately aligned bimgan .
