Printing system using liquid crystal shutter matrix panel

Abstract

Abstract PURPOSE:To attain excellent light utilization rate and to accelerate the exposure speed by using a signal from a picture data generating means to drive a shutter of a liquid crystal shutter matrix panel, forming a picture and transferring the picture onto a photosensing material. CONSTITUTION:A liquid crystal shutter matrix panel 26 is lighted from a rear face with a 2nd light source 22 controlled by a pulse generator 14. A digital picture data is fed from a picture data generator 31 as a picture data generating means comprising a data processing unit such as a microcomputer to a picture recording section 29 as a picture recording means via a liquid crystal drive circuit 12 during the panel 26. The picture formed by the panel 26 is formed on a photosensing material 41 with an image forming optical system 28. The material 41 is placed on a moving means 32 controlled by X, Y axis pulse motors 34, 36 and positioned to the recording position corresponding to the recording section 29. An original 43 is subjected to position control by the means 32 and positioned on the picture read position corresponding to the picture read section 47 and the picture on the original 43 is lighted by a 1st light source 42.
