ザービームプリンタ。[Claims for Utility Model Registration] (1) In a laser beam printer that scans a laser beam and irradiates it onto a photoconductor, a laser optical system includes a reflecting mirror that guides the laser to the photoconductor and a predetermined position on the photoconductor. The beam detector has a slit through which the laser beam irradiated passes through and a beam detector that obtains a synchronization signal in the scanning direction of the laser beam, the slit is attached to a member that holds the photoreceptor, and the beam detector has a , characterized in that the laser light is irradiated without passing through the reflective mirror, and the laser light that is the image light is guided to the regular laser irradiation position on the drum through the reflective mirror and through the slit. laser beam printer. (2) The laser beam printer according to claim 1, wherein the slit is removable.
