摘要： A beam light scanning apparatus capable of reducing influences of variations in characteristics of circuits disposed in a signal path extending until a laser driver and speeding up image data transfer for scan and exposure. Data of each line is distributed by an image data I/F into data trains of two channels, i.e., an odd-numbered pixel train and an even-numbered pixel train. The data in the two-channel trains are written by writing units into a plurality of memories in parallel for each of the trains in response to a line sync signal. During the same processing cycle as that for the writing, the data are read out of the memories in parallel by reading units. The data of two channels are combined by a multiplexer into a data train in the original order of pixels in each line, and a driving signal based on the combined data is generated by a PWM. A laser is driven by the driving signal.

摘要： A beam detection sensor detects power of a laser beam from one of a plurality of light sources for each scanning of a scanning section to provide a light power signal. A laser control circuit compares a value of the light power signal with a predetermined value, adjusts a terminal voltage of a capacitor based on a result of the comparison, controls emission power of one of the light sources in accordance with the terminal voltage of the capacitor, and executes the control once for each light source during a plurality of scanning operations. An APC correction circuit corrects a reduction in the power of a laser beam in accordance with a reduction in electric charges applied to the capacitor caused by a leakage current during the plurality of scanning operations.

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： An image forming apparatus includes a light generator (e.g., laser) generating a scanning light beam and a driver driving the light generator depending on a drive signal to be provided. In this apparatus, data formed of image information at each pixel of each line along a main scan direction of an image to be targeted are distributed into a plurality of strings (i.e., channels) of data (e.g., two strings). Concerning each pixel provided by data in each string, information indicative of both a start and an end of modulation (e.g., PWM) is then produced. By using the start and end information, a modulator performs modulation depending on the data of each pixel in each string, providing a modulated signal. The modulated signals from the plural strings are mutually synthesized at synchronizes timings, being provided as the drive signal and given to the driver.
