| titleOfInvention | Light source device of the laser scanning unit |
| abstract | BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a light source device of a laser scanning unit, wherein a self-monitoring laser device (SELF-MD) that scans a beam and directly senses the amount of scanning is placed on the surface of a rotating body to simultaneously scan and detect a laser beam. To do it.n n n The present invention is a laser scanning including an imaging lens for imaging the photosensitive drum by performing scanning at a uniform speed while causing the laser beam obtained from the light source to be deflected at an isotropic speed through the polygon mirror to deflect from the deflection surface. A unit, comprising: a drum motor rotating at constant speed; A fixed drum coupled to the main body of the laser scanning unit; A rotating drum spaced apart from the upper surface of the fixed drum at a predetermined interval and rotatably supported by an axis of the drum motor passing through the fixed drum; And at least two self-monitoring laser devices (SELF-MD) mounted on the circumferential surface of the rotating drum at predetermined angles to emit a laser beam through the imaging lens and sense the amount of scanning. It is done.n n n Accordingly, it can be seen that the structure is simplified by scanning the laser beam and simultaneously detecting the scanning amount without using the existing horizontal synchronization mirror and optical sensor. |
