Abstract: PURPOSE:To enable color exposure with one cathode-ray tube and without changing a filter and to miniaturize the title device by obtaining one scene of exposure picture of the video screen of the cathode-ray tube and providing, to the video screen, three kinds of light emitting parts whose wavelengths of emission virtually differ from each other. CONSTITUTION:The cathode-ray tube 39 as an exposure light source is made a single- electron-gun constitution, and its video screen 40 of the tube 39 is made capable of obtaining one scene of exposure picture, besides, the screen 40 is divided into the three kinds of light emitting parts 40R, 40G, 40B whose wavelengths of emission virtually differ from each other. A video obtained on the video screen 40 comes through an image forming lens 33 and image-formed on a photosensitive material 1. To this cathode-ray tube 39, color video signals to form one scene of exposure picture are supplied in repetition for a prescribed number of times. Further, a video on the screen 40 of the tube 39 is shifted in the vertical direction of the sequential video screen 40 with a one-horizontal-scanning-pitch in synchronizing with vertical synchronizing signals, and further, the photosensitive material 1 is relatively moved in the vertical direction of the screen 40 against the screen 40 itself in synchronizing with the shifting of the video on the screen 40.

Abstract: PURPOSE:To miniaturize the device, to reduce the cost, and also, to eliminate unevenness of the developing density by constituting the title device so that a relative attitude to a stage of the roller can be adjusted automatically and correctly by press-contacting of the stage and the roller. CONSTITUTION:On at least one of a stage 7 and a roller 60, aligning means 53, 62, 63 and 66 for executing an adjustment automatically so that an attitude against the stage 7 of the roller 60 becomes correct by their relative press- contacting are provided. Accordingly, the roller 60 being one component of a press-contacting means for bringing a photosensitive material 68 and a developed material 70 to press-contacting to each other moves so as to scan to the photosensitive material 68 and the developed material 70, therefore, a shape of the press-contacting means and pressing force required for the press- contacting means can be made small. In such a way, the developing device can be made small in size and light in weight, and its cost can be reduced. Also, a relative attitude to the stage 7 of the roller 60 is adjusted automatically by the aligning means 53, 62, 63 and 66 and a correct attitude is always held, and unevenness of the developing density can be eliminated.

Abstract: PURPOSE:To prevent developing paper from damaging by forming a step which is as thick as the developing paper between the mount surface of a stage for the developing paper, etc., and stand-by surfaces on both sides, making the mount surface lower than the stand-by surfaces and sending the developing paper by specific pitch while a roller is positioned on a stand-by surface. CONSTITUTION:The step 8c which is as thick as the developing paper 67, etc., is formed between the mount surface 8a of the stage 7 for the developing paper 67, etc., and the stand-by surfaces 8b and 8b' positioned on both sides, the mount surface 8a is made lower than the stand-by surfaces 8b and 8b', and the developing paper 67, etc., is sent by the specific pitch while the roller 58 is positioned on the stand-by surface 8b. Therefore, when the roller moves from the stand-by surface to the mount surface, the roller is prevented from being caught by the edge of the developing paper. Consequently, the edge of the developing paper is prevented from being damaged by the roller.

Abstract: PURPOSE:To reduce the size and weight of a device and to execute clean development without having unequal development densities by bringing a photosensitive material and color developing paper into pressurized contact with each other by means of rollers and a stage and providing notches to either of the rollers or stage. CONSTITUTION:The rollers 52, 52' which are the pressurizing means for bringing the photosensitive material 59 and the color developing paper 61 into pressurized contact with each other are movable for the purpose of scanning the photosensitive material 59 and the color developing paper 61. Either of the rollers or the stage is partly notched to prevent the contact pressure between the rollers 52, 52' and the stage 7 from rising higher in both end parts in the direction orthogonal with the rolling direction of the rollers than in the other parts. The shape and pressurizing force of the pressurizing means can, therefore, be fairly reduced and the need for using powerful spring members and increasing the mechanical strength of the respective parts is consequently eliminated. Furthermore, the parts where the contact pressure between the rollers and the stage rises abnormally high are eliminated. The clean development without having the unequal development densities is thereby executed with the small size at the low cost.

Abstract: PURPOSE:To form an image superior in resolution on a photosensitive member with simple, inexpensive constitution by providing a particulate which does not transmit ultraviolet rays movably in the space between the 1st and the 2nd control electrodes on which the ultraviolet rays are incident. CONSTITUTION:A common electrode 5 which has the particulate 6 in a groove and a control electrode 1 are provided in a transparent case 3 and a contact A of a switch X is normally made to apply a DC voltage DV to the common electrode 5. When the switch is changed over to a contact B on the basis of the image signal Sv of an image signal generating circuit 7b, an AC voltage AV is supplied to the electrode 5 and the particulate 6 moves between the electrodes 1 and 5 with the electric field between the electrodes 1 and 5; when photosensitive body on the reverse side of the case is exposed to the ultraviolet rays from a ultraviolet rays source 15, they are cut off in the presence of the particulate 6 to form an image pattern. Thus, the ultraviolet rays are easily controlled and the image having superior resolution is formed on the photosensitive paper.

Abstract: PURPOSE:To perform repeatedly photographic image forming process by using the light having a wavelength band approximately equal to the sensitivity wavelength band peculiar to a photoconductor in the cleaning exposure where the electric charge remaining on electrophotographic sensitive materials subjected to coloring matter sensitization is removed. CONSTITUTION:For example, a poly-N-vinylcarbazole film is wound around a rotating durm 1, and its surface is electrified negatively by a corona charger 5 each time when the rotating drum 1 is rotated once. At this time, a photosensitive material film 15 is grounded through the rotating drum 1. This electrified photosensitive material film 15 is exposed through a SELFOC lens array 7 by a CRT scanner 6 to which R, G, and B picture signals are given successively. Developing devices 8-10 are moved to developable positions successively to develop the film 15 with individual color toners, and a color image is obtained by three rotations of the rotating drum 1. When a fluorescent discharge tube is used as a cleaning exposure device 14, three-color signals are subjected to exposure in the same level to obtain the color image of good color balance.
