摘要： Four beams are caused to scan a scanning surface in the main scanning direction in parallel. The beams expose the target area between two optical sensors, not the surface of a photosensitive drum, to produce correction data to correct shifts in the exposure positions of the four beams in the main scanning direction with an accuracy of less than a small fraction of one pixel. On the basis of the correction data, an actual image formation area is set on the photosensitive drum. This makes it possible to always control the relative exposure scanning position accurately even when the relationship between the main scanning positions of the light beams is unknown.

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.

Upon executing a digital process on the basis of analog detection value Vo corresponding to the passage position or light beam power of a light beam with which a photosensitive drum is irradiated, comparator CMP0, comparison reference value (threshold value) Vr of which changes in correspondence with detection value (integration output) Vo, is used. New comparison reference value Vr is supplied to comparator CMP0 on the basis of digital data BMDA corresponding to output CMPOUT of this comparator.

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： A four-line CCD sensor is structured by line sensors R, G, B in which color filters are respectively disposed on surfaces of light receiving elements, and a line sensor BK at which no color filter is disposed. Amplitudes of signals which are outputted from the line sensors R, G, B at a time of reading a color document, and an amplitude of a signal which is outputted from the line sensor BK at a time of reading a monochrome document are adjusted so as to be substantially equal to one another. In a case in which a color document is read, outputs of the line sensors R, G, B are selectively provided, and in a case in which a monochrome document is read, output of the line sensor BK is selectively provided.

摘要： A synchronization signal detector receives a laser beam each time it is scanned in a main scanning direction, and detects a synchronization signal from the received laser beam. An external circuit or the like sets a binary value-determining level for this detector. The binary value-determining level is so determined as not to generate a signal arising from stray light. By this determination, a synchronization error, which is due to stray light, is prevented without adding manufacturing steps to prevent the stray light or without incurring an increase in the cost needed for structural components.
