Title: Image forming device using light beam
Inventor: ISAKA KAZUO
IPC: H04N1/113
Filed: 1991-11-06
Abstract: PURPOSE:To realize a recording device wherein reproducibility of gradation property is improved by scanning first and second light beams of which one has image information, in such a manner that each beam is superposed on a moving photosensitive body after a lapse of time. CONSTITUTION:An image data signal sent from an image data memory 7 is sent to a laser drive circuit 10A and a line buffer 8, and is delayed at a delay circuit 9 by a predetermined time T and sent to a laser drive circuit 10B. The laser drive circuit 10B makes an image based on the image data memory 7 emitted by a semiconductor laser 1 at a timing different by the predetermined time T. On a photosensitive material 5, the same information is exposed on the same point twice by deviating the timing by the predetermined time T at the delay circuit 9. Thus, by recording the same image information twice on the photosensitive material 5, laser outputs of a first image record and a second image record are made to be different from each other, so that gradation property can be improved.
