Abstract: PURPOSE:To shorten the exposure time of the titled sheet by directly projecting a light coming from an exposure source to a microcapsule, and again by exposing the microcapsule reflecting by a substance having high photoreflectance, thereby radiating the light coming from the exposure source on the both surfaces of the microcapsule. CONSTITUTION:The image light of a display image is radiated on the microcapsule layer 2 of the titled sheet 1 through a lens 6 and a color filter 7 to expose said sheet. The irradiated image light reaches to a light reflecting layer 1b transmitting the microcapsule layer 2, and again allows to make incident on the microcapsule layer 2 by reflecting on said layer 1b. And, also the image light is radiated on the microcapsule layer 2 from the opposite side of said layer 2 which is directly irradiated from a cathode ray tube 5 by the reflecting light coming from said microcapsule layer 2. The microcapsule layer 2 of the titled sheet 1 is directly exposed by the image light coming from the cathode ray tube 5, and at the same time, is exposed by the image light reflected on the light reflecting layer 1b, thereby exposing said layer 2 irradiating said image light on the both surfaces of said layer 2. Thus, as the titled sheet is irradiated with about two times of exposure, comparing with the exposure of the titled sheet which is not provided with the light reflecting layer 1b, the exposure time is shortened.

Abstract: PURPOSE:To effectively radiate a light beam from an exposure source on both surfaces of a photosensitive sheet and to shorten an exposing time by reflecting the light beam transmitted through the photosensitive sheet from the exposure source by a surface mirror and radiating it on the photosensitive sheet. CONSTITUTION:The photosensitive sheet 1 is arranged so that it abuts on the surface mirror 8 and an image which should be exposed is displayed with a cathode-ray tube 5. The image light l of the displayed image is radiated on a microcapsule layer 2 on a photosensitive sheet base 1a through a lens 6 and a color filter 7 so as to execute the exposure. The transmitted light is reflected on a reflecting part 8a and is made incident on the photosensitive sheet base 1a again. The image light is radiated on the microcapsule layer 2 from the opposite side to a direct irradiation from the cathode-ray tube 5 so as to execute the exposure. The microcapsule layer 2 is exposed with the image light which directly reaches from the cathode-ray tube 5 and it is radiated to be exposed with the image light which reaches by reflecting by the surface mirror 8 from both surfaces. If the luminance of the cathode-ray tube is same, the light quan tity which is nearly twice as much as in the case where there is no surface mirror can be radiated and the exposing time can be shortened.

Abstract: PURPOSE:To easily form an excellent reflection type image only by an electrophotographic process by forming an image on a transparent electrophotographic sensitive body by the electrophotographic process and developing the entire surface with white toner. CONSTITUTION:The photosensitive body 3 constituted by forming a transparent photosensitive layer 2 on a transparent base 1 is changed uniformly and electrostatically by corona discharging and then the charge is attenuated by an image exposure to form an electrostatic latent image on the surface of a photosensitive layer 2. Then, toner which is charged electrostatically to an opposite polarity is used for wet or dry development to form a toner image 4 on the surface of the photosensitive layer 2. Then the photosensitive body 3 on which the toner image 4 is formed is corona-discharged to charge the surface of this photosensitive body 3 uniformly, and the white toner 5 which is charged to the opposite polarity is used to develop the entire surface.

Abstract: PURPOSE:To easily and surely decide a picture read range by superimposing a picture data read from a picture memory onto an output signal from a frame generating circuit, forming display signal and reading the inside of a decided frame range again. CONSTITUTION:A picture data read by a picture read head 2 from a picture original is stored in a picture memory 8. Then a signal of a key input device 23 is fed to a CPU 22, which controls a frame generating circuit 30 in response to the key entry to generate the picture read range display frame. Then the frame display signal of the circuit 30 is fed to a superimposing circuit 12, where the signal is superimposed on the picture signal from the memory 8. Then a read timing control circuit 9 is controlled via a system control circuit 21 to read the picture read range decided in the picture original. Thus, the read range is easily and surely decided and the decided read range is again read to display the picture without deterioration.
