Abstract: One or more light beams are deflected and all beams then combined and scanned by common optical system. Beam positions are detected before scanning mechanism to provide first correction data and after scanning when scanned beams reach recording surface to provide second correction data and two sets are used together to correct beam deflection and thus position of scanned beams. Beam deflector is two-dimensional or number of one-dimensional acousto-optical or electro-optical devices. Independent claims are included for (a) a light beam scanning apparatus (b) and a method of controlling a drive operation of a light beam scanning apparatus.

Abstract: A method for correcting recording positions of light beams scanned by a light beam scanning apparatus, in which at least one of plural light beams is deflected by an optical deflecting device and all the plural light beams are combined and scanned by a common scanning optical system. The beam position correction data for the optical deflecting device for keeping positions of the light beams constant is obtained by detecting the beam positions before the scanning optical system. The recording positions of respective light beams on a recording surface is also detected to obtain an additional correction data for correcting deviations of the recording positions due to uneven optical power distribution of the light beam or astigmatism of the scanning optical system. The additional correction data is added to the beam position correction data to obtain the final correction data, by which the optical deflecting device is controlled.

Abstract: A photosensor (20a) has a pair of n-type semiconductor layers (21U, 21D) formed on the major surface of a p-type semiconductor substrate (31). A light-shielding pattern (24) comprised of unit light-shielding layers (33) is formed on the major surface of the substrate. When the major surface is scanned by a light beam in the direction (D X ) in which the unit light-shielding layers are aligned, a couple of photo-conversion signals indicating a current position of the light beam on the photosensor are generated in the photosensor. Since the light-shielding pattern is directly provided on the sensor body, no grating glass is required other than the photosensor.

Abstract: In an image sensor including a light emitting element for emitting a light beam to be incident on a document, a light receiving element for receiving the light beam reflected by the document, and a lens array for directing the reflected light beam from the document to the light receiving element, there is located a mirror between the lens array and the light receiving element for changing the direction of the light beam passing through the lens array. The light emitting element and the light receiving element are located on the same substrate. With this arrangement, a compact and inexpensive image sensor can be achieved. This compact image sensor causes an increased amount of light to be incident on the document.

Abstract: The apparatus includes a primary scanner including laser light sources (10B, 10C) and rotating polygonal mirror (12), which produces a scanning optical beam on a drum (16), and a photoresponsive error sensor (22, 24, 28) which effectively measures over the scan path the successive differences between the actual position of the scanning beam and the desired position of the scanning beam and produces error signal. A secondary scanner (30, 32) is connected to the error sensor for response to the error signals to dynamically correct the position of the scanning beam during the course of the scan. The primary scanner provides a main optical scanning beam and an auxiliary optical scanning beam (20C) traversing substantially the same optical path. The error sensor includes a graticule mask (22) having a substantially uniform optical density along the desired scan path and a graded optical density transverse to the desired scan path of the auxiliary scanning beam.
