摘要： PURPOSE:To improve the color reproducibility by lighting a spectral energy adjusting auxiliary light source provided in a light source part to correct the R exposure or the gray balance in case of exposure of a C printer or black printer original. CONSTITUTION:In the method where each of halftone negative originals separated to component colors is subjected to multiple exposure once to form a color image, the spectral energy adjusting auxiliary light source provided in the light source part is lit to correct the R exposure or the gray balance in case of exposure of a C printer or black printer original. That is, a three-wavelength fluorescent tube 302A as a tubular light source lamp and a halogen lamp as an auxiliary light source 302B in the central part are surrounded with a cylindrical body 321, which is fixed to an enclosure 316 and has inside face reflection mirrors 306A and 306B and a light diffusing plate 304, with respect to the structure of a multiple exposure light source device 300. Thus, image exposure of good color reproducibility is equally performed when a positive color photosensitive material as well as a negative color photosensitive material is used for multiple exposure in a printing plate checking device or the like.

摘要： PURPOSE:To set exposure quantity free of reciprocity and to attain appropriate exposure by providing a photosensitive layer of low sensitivity color with a high illuminance light source free of low illuminance reciprocity, slowing down a scanning speed with respect to said layer and conversely speeding up scanning with respect to a photosensitive layer of high sensitivity color. CONSTITUTION:When a negative color is used for photosensitive material and a fluorescent lamp is used for a light source, they may be less sensitive to R light. In that case, a high illuminance lamp free of low illuminance reciprocity with respect to an R sensitive layer is loaded as the light source lamp of a polygonal cylinder 301 in an exposing part 300. When the R light is exposed, a scanning speed is slowed down to cope with the R light. A slit width changing device 317 provided on an exposure window 310 changes the size of a slit, which contributes to the prevention of reciprocity. Plural light source lamps 302A-302C are loaded so that in case of R light projection, high illuminance is attained, whereas in case of other G and B light types, much lower illuminance is attained. Thus, the phenomenon of low illuminance reciprocity can be evaded in synthetic exposure from printed originals, and reciprocity row can be maintained stably, thereby obtaining a fully colored image with high quality.

摘要： PURPOSE:To properly and surely carry even a photosensitive material having a curling habit along a carrying path by making the carrying speed of the processing speed in the preceding stage faster than that in the succeeding stage and moving a guide member by means of a loop of the photosensitive material formed between the preced ing and succeeding stages, and then, controlling the carrying speed of the processing process in the preceding stage by detecting the movement of the guide member. CONSTITUTION:Carrying rollers 131a and 132a which are driven by a drive motor MA are provided on an exposure device A side and carrying rollers 201a which are driven by another drive motor MB are provided on an automatic development processor B side. The carrying speed of the rollers 131a and 132a is set faster than that of the rollers 201a. Photosensitive materials are stocked between the rollers 132a and 201a as time elapses and a loop is formed by the elastic photosensitive materials held by a curved carrying path and the carrying rollers 201a. Then a movable guide plate 137a is pushed upward and a detecting means 133a and which is pushed by the back of the plate 137a is turned on. Therefore, even a photosensitive material having a habit of curling, etc., can be carried surely.

摘要： PURPOSE:To solve the phenomenon of the blurring and interlacement of dots, and to improve dot reproducibility, that is, image gradation at the contact multiple exposure of each discomposed dot original film to a photosensitive material by interrupting diagonal incident lights. CONSTITUTION:Since in a condition in which a transparent cover sheet 275 is set, the both edges of cover sheet are positioned a little lower than an original platen surface, the cover sheet is pressed on the original platen and a photosensi tive material placing platen surface on which an original dot film and the photo sensitive material are placed. In this condition, a squeeze roll 276 is squeezed and air between the transparent cover sheet and the original platen is removed. Thus, excellent contact plane condition is recurred. Regarding rays of light sent from a tubular light source through a transparent window and the filter, the oblique rays of light of them are almost absorbed by a black wall plane and only parallel rays of light or the rays of light approximately in parallel pass a honeycomb board 342. Thus, the rays of light are exposed from a cover sheet side through the honeycomb board. Hereby image formation which is high in the dot reproducibility, that is, in gradation in response to a dot original is performed.

摘要： PURPOSE:To accomplish smooth operation and reproducibility with high picture quality without generating fogging caused by pressure or static electricity by using conductive resin material as the material for the table surface of a photosensitive material placing table, and making the surface in the form of a mat. CONSTITUTION:When a photosensitive material is carried and placed on the photosensitive material placing table 201, a blower applies sucking force to a suction hole pierced on the table 201, so that the photosensitive material is firmly fixed to the table 201. With respect to the photosensitive material placing table 201, a cover 292 is fitted to a suction box 291, and a vinyl cloride sheet 296 containing conductive carbon is attached to the surface 201M of the cover 292; the sheet 296 has a suction hole likewise the cover 292, and its surface is used as a table onto which a photosensitive material is placed. Thus, the photosensitive material can be smoothly peeled by attaching the mat-like vinyl chloride sheet containing the conductive carbon to the cover 292, and by peeling the photosensitive material placed on the surface 201a by releasing from suction. Thus, work efficiency is improved, and fog trouble is surely prevented.
