Title: Optical scanner
Inventor: IMAMOTO MASAMI
IPC: H04N1/23
Filed: 1982-04-15
Abstract: PURPOSE:To always maintain the spot diameter on a photosensitive drum at a fixed value regardless of the scanning position of the spot, by controlling dynamically the aperture diameter of a laser light by means of a slit plate. CONSTITUTION:For an aperture controller 7, a driving current which varies in response to the deflecting angle theta (an angle to a line vertical to the sensitive surface of a photosensitive drum 4) of a beam, i.e., the scanning position of a spot is applied to an aperture controlling circuit 8. Thus the controller 7 varies dynamically the angles thetax and thetav of inclination of slit plates 72 and 75, respectively. When the angles thetax and thetav vary, the aperture diameter D of the laser beam passing through the slits 71 and 74 is partially prevented by the plates 72 and 75 to be stopped down. This stop-down degree corresponds to the angles thetax and thetav. The spot diameter omega on the drum 4 is shown in the following equation. That is, omegao=[4lambdal/piD] and omega=omegao[1+{4lambdaZ/piomegao}<2>]<1/2>, where lambda is the wavlength of laser light, l is the distance from the aperture part to the image forming position, omegao is the spot diameter at the image forming position, and (z) is the distance from the image forming position to the surface of the drum 4, respectively.
