Title: Optical printer
Inventor: YAMAGUCHI TAKASHI
IPC: B41J3/00
Filed: 1983-09-30
Abstract: PURPOSE:To obtain a high frequency timing clock signal without changing a slit interval nor increasing the scanning speed of a light beam by dividing a light beam for the detection of a deflecting position and scanning a slit plate with the divided lifht beam. CONSTITUTION:The light beam made incident to a rotary polyhedral mirror of an optical printer is divided into a writing beam and a light beam for the detection of the deflecting position. Then a slit plate 7 containing an array of slits is scanned by the reflected beam of the position detecting beam and according to the revolution of the polyhedral mirror. In this case, the light beam is divided by a light beam dividing means (not shown in the figure) into the light beams A-D. When these beams A-D scan the plate 7 in the main scanning direction, the phase is shifted in the secondary scanning direction by an amount that avoids the overlap among beams A-D. Thus a compound clock is delivered without changing the interval of a slit 7A and the scanning speed of the light beam.
