IPC: G02B26/10
Filed: 1992-11-12
Abstract: PURPOSE:To improve safety of a regulating person in regulating a light receiving element in a condition where a light source is on. CONSTITUTION:A light beam deflected and scanned by a polygon mirror 45 is radiated from a glass plate 54 through optical elements 50, 51, 52, 53 to an outer part of a printing head. A shutter plate 60 is installed to be capable of advancing into a light way of the light beam, and when a cover 102 is closed, the shutter plate 60 releases the light way. When the cover 102 is opened, the shutter plate 60 shields the light beam to prevent the light beam from leaking outside the printing head. In the meanwhile, part of the light beam deflected and scanned by the polygon mirror 45 is branched by a mirror 35 to be guided to an SOS sensor. The shutter plate 60 can thus shield the light beam to the external without shielding the light beam guided to the SOS sensor.
