摘要： A light beam position detecting device detects the passage positions of a plurality of light beams for scanning the surface of a photosensitive drum. The light beam position detecting device has a sensor pattern for generating an output which is continuously changed in a wide range with a variation in the passage position of the light beam in a sub-scanning direction perpendicular to a main scanning direction of the light beam. The sensor pattern precisely detects the relative scanning position of the light beam in a wide range. The passage positions of the plurality of light beams for scanning the surface of the photosensitive drum are controlled to a preset position based on the output of the sensor pattern.

摘要： A pair of sensor patterns detect a passage position in a sub-scan direction of a light beam scanned over a surface of a photosensitive drum. The sensor patterns have, for example, trapezoidal shapes and are disposed symmetrical at a position equivalent to a position of the surface to be scanned. The sensor patterns are juxtaposed in a scan direction of the light beam at a predetermined interval therebetween. An output integration value from one of the paired photodetector elements successively increases while an output integration value from the other photodetector element successively decreases in relation to a variation of a passage position of the light beam in the sub-scan direction. On the basis of a difference between the output integration values of the paired sensor patterns, the passage position of the light beam in the sub-scan direction is detected.

摘要： A light beam is made to scan and expose a photosensitive drum in the main scanning direction and the passing position of the light beam in the sub-scanning direction is sensed. On the basis of the result of the sensing, the light beam is shifted in the sub-scanning direction when the beam is made to scan by a scanner so that the passing position may come in a target range, which brings the passing position to the proper position. After the position control, the passing position of the light beam is confirmed and controlled so that the passing position may fall on the proper position a specific number of times consecutively. When the light beam is shifted in the sub-scanning direction, the passing position of the light beam is brought into a final target range in such a manner that the target range is forced to converge stepwise in a first range and then in a second range narrower than the first range.

摘要： In a printer head constituted by a large number of linearly arranged LEDs, a lighting time designator receives image data at a period corresponding to one scanning period, designates a lighting time of each LED within one scanning period in accordance with image data corresponding to each LED and the lighting capacity of each LED, and outputs lighting time data. A lighting mode designator determines a lighting mode for designating a timing, within one scanning period, at which each LED is caused to emit light, on the basis of image data, and outputs lighting mode designation data. A light timing controller divides one scanning period into a plurality of time intervals and supplies the lighting time data to the printer head a plurality of number of times within one scanning period at the time intervals on the basis of the lighting mode designation data, thereby selectively causing the respective LEDs to emit light.
