    Abstract: To make it possible to improve a printing speed.When printing a plurality of printing sheets 14, it is possible to decrease the time for generating correction data by using a pair of correction data values to print the printing sheets 14. Therefore, it is possible to decrease the time for printing each printing sheet 14 even compared to the case of a method for generating correction data for each printing sheet 14. As a result, even when the number of sheets to be printed is large, it is possible to improve a printing speed. Moreover, when meandering states of the printing sheet 14 are changed, it is possible to prevent disorder of a printed image due to meandering of the printing sheet 14 for a long time by newly generating correction data. Furthermore, by generating (updating) only a part of correction data when newly generating the correction data, it is possible to decrease the time for generating the correction data and improve a printing speed.

    Abstract translation: 以提高打印速度。 当打印多个打印纸张14时，可以通过使用一对校正数据值来减少用于产生校正数据的时间来打印打印纸张14。 因此，即使与用于生成每个打印纸张14的校正数据的方法的情况相比，也可以减少打印每个打印纸张14的时间。 结果，即使要打印的纸张数量大，也可以提高打印速度。 此外，当打印纸14的曲折状态改变时，可以通过新产生校正数据来防止长时间由于打印纸14的曲折而导致的打印图像的混乱。 此外，通过在新生成校正数据时仅产生（更新）一部分校正数据，可以减少生成校正数据的时间并提高打印速度。

The optical scanning unit includes a resonant mirror controller scanning light emitted from a laser diode on a photoconductive drum, a first receive light sensor which receives the light scanned by the resonant mirror controller, and outputs a first horizontal synchronization signal which determines a start position of optical scanning according to the received light, and a video signal controller, responding to the first horizontal synchronization signal output from the first receive light sensor, controls the laser diode so that light corresponding to a video signal is emitted. In the optical scanning unit, a video signal controller can receive a plurality of horizontal synchronization signals (SOS; Start of Scan) through only one input pin irrespective of the number of receive light sensors which generate horizontal synchronization signals (SOS; Start Of Scan), which correspond to a start position of optical scanning.

    Abstract: An image forming apparatus includes a light source, a deflector, beam detectors, a clock generator, a measurement mechanism, a frequency corrector, and a phase corrector. The light source illuminates in response to image data. The deflector deflects an optical beam into a scanning beam. The beam detectors including first and second beam detectors detect the scanning beam. The clock generator generates writing clock signals. The measurement mechanism measures a count number of the writing clock signals generated during a period between the scanning beam is detected by the first and second beam detectors. The frequency corrector corrects a frequency of the writing clock signals such that the count number measured becomes substantially equivalent to a predetermined number. The phase corrector varies a phase of the writing clock signals such that the count number is substantially constant before and after the phase of the writing clock signals is varied.
