露光の調節を行う。The white light W emitted from the exposure white light FAI through the condensing lens 8 is deflected by the spectroscopy prism 2. It is divided into spectra. The separated spectral light is irradiated onto the liquid crystal shutter 3. At this time, blue light B in the spectrum light, ! A liquid crystal shutter 3 for blue light exposure is installed at the position where the colored light G and red light R components are separated and irradiated.
A, a liquid crystal shutter 3 for green light exposure, b, and a liquid crystal shutter 3c for red light exposure are arranged. An imaging lens 5 is provided at the bottom of the liquid crystal shutter 3, and each color light that has passed through the liquid crystal shutter passes through the imaging lens 5, forms an image on the photosensitive paper 4, and is exposed. . The photosensitive paper 4 is fed by a paper feed roller 6 in the paper movement direction (arrow Z direction). At this time, each of the blue light B, green light G, and red light R1 selectively transmitted by the liquid crystal shutter 3 is exposed to the photosensitive paper one line at a time. Although the exposed photosensitive paper is omitted from the figure,
The image is reproduced through a developing and fixing process. The red, green, and I color lights exposed onto the photosensitive paper 4 pass through the liquid crystal shutter 3 and enter the imaging lens 5. At this time, exposure is adjusted by selectively blocking q by the 0N10FF state of the liquid crystal shunter.
