CONTROLLER FOR IMAGE FORMATION FOR ADJUSTING HORIZONTAL SYNCHRONIZATION OF DUAL BEAM LASER SCANNING UNIT

摘要

The invention of the clock generating unit, and a dual beam laser of the two horizontal synchronization signal, receiving the phase difference by the offset calculating clock of the two horizontal sync projecting from a transfer unit for generating a frequency division to the video output clock and the offset output clock to the reference clock and an offset calculating an offset according to the phase difference calculation section, according to the video output clock as to correct the phase difference on the basis of the offset calculated by the unit offset calculating comprises a video output controller for delaying the output of the video signal to be printed It provides an image forming controller for correcting the horizontal synchronization of a dual beam laser transfer unit.
