Multi laser beam image recording device for laser printer pulse-width modulates interference data output from memory in sequence in which they were written based on delay data

摘要

Device has multiple light sources for exposing light-sensitive drum. Image signals corresponding to each light source are made to interfere only with preset light quantity components. Pixel clocks corresponding to each light source are delayed by preset delay times. Interference data are synchronized with pixel clocks and written to memory, and output in sequence in which they were written according to delayed data output from delay device. Interference data are output from memory and pulse-width modulated. Eight Independent claims are included for an image recording device.
