欠点があった。(Problems to be Solved by the Invention) However, impact type printers have the disadvantage that there is a limit to printing speed due to the operating time of the hammer, intermittent movement of paper feed, etc., and they also generate large noise. In addition, there are various types of non-impact printers, but an example is an electrophotographic type that uses laser light, which uses a laser light source and a laser light to transform the light image to be printed according to the printing information. In addition to the sequential conversion scanner, it requires a large number of components such as a charging drum, toner adhesion means, printing paper feeding means, transfer electrodes, etc., resulting in a complex structure and high cost, as well as the disadvantage that the printing paper is expensive.
本発明の目的は、上記の欠点を回避し、印字速度を低下

A light image forming means 14 consisting of a liquid crystal shutter that controls on/off the ultraviolet rays from the ultraviolet source 12 for each pixel according to printing information to obtain a light image to be printed; diazo-sensitive paper feeding means 18 for feeding the diazo-sensitive paper 16 into the optical image path from the optical image forming means 14;
and a developing means 20 for developing the diazo photosensitive paper 16' that has been exposed to a light image.

分方式のいずれの方式でもよい。The diazo photosensitive paper 16 and the developing means 20 are the same as those normally used in the diazo copying system, and use the principle that the diazonium salt on the photosensitive paper undergoes a photodecomposition reaction upon exposure and loses its coupling ability. Either a two-component method in which two components, a diazonium salt and a coupling component, are applied to the photosensitive paper or a one-component method in which the coupling component is dissolved in a developer may be used.
