Document Type and Number:
Japanese Patent JP2515877
Kind Code:
B2
Abstract:
PURPOSE:To accomplish precise exposure control and to improve light using efficiency by printing and exposing a photosensitive material with a beam which transmits an original picture through the use of laser lights the optical spectrum band of which is narrow. CONSTITUTION:Laser lights oscillated from laser light sources 10, 11 and 12 for three colors are converged into a beam for example, by a mirror 16 and dichroic mirrors 17 and 18 and are image-formed in the form of a spot on the reflecting surface of a galvanomirror 20 by a first condenser lens. Then the beam reflected on the galvanomirror 20 is image-formed in the shape of a spot on the reflecting surface of a polygon mirror 23 by a second condenser lens. The reflected beam scans an original picture, for example an image recorded on a negative film and transmitted light is exposed on color paper 26 arranged behind the original picture in a spot. Hereby precise exposure control is accomplished and a gradation can be changed without lowering the light using efficiency.
