Abstract: PURPOSE:To obtain a color print whose color tone is excellent by specifying the ratio of width of light emitting parts of each wavelength light of the light emitting surface of a cathode ray tube being an exposure light source and executing the compensation of the light emission efficiency and the exposure sensitivity. CONSTITUTION:The title device is provided with the cathode ray tube having a light emitting surface 21 consisting of three kinds of first-third band-like light emitting parts 211-213 of each different peak wavelength in a light emission wavelength area. Also, the ratio of each width D1-D3 of each of the first-the third light emitting parts 211-213 of the cathode way tube 20 is selected in accordance with the ratio of an inverse number of the product of the light emission intensity of each light emitting part 211-213 and the sensitivity of a photosensitive material 1 against three kinds of light beams from these light emitting parts. Accordingly, even when said light emission intensity or sensitivity is different with regard to each color (wavelength), the substantial photographic sensitivity, namely, the photosensitive efficiency can be equalized. In such a way, a color print having a satisfactory color tone can be obtained.

Abstract: PURPOSE:To simplify and miniaturize the whole of a device by applying the oscillation pressing force of an oscillating member, which is oscillated in the thickness direction of a photosensitive material which is selectively exposed to a specific light, to this photosensitive material to crush unhardened parts of a photosensitive agent in microcapsules of the photosensitive material. CONSTITUTION:The specific light including a prescribed wavelength band irradiates the photosensitive material supplied from a photosensitive material supply means by an exposure processing part 8 to perform selective exposure, and the photosensitive agent in many microcapsules of the photosensitive material is hardened. In a development processing part 16, the photosensitive material subjected to selective exposure receives the oscillation pressing force applied by the oscillating member which is oscillated in the thickness direction of the photosensitive material. Consequently, unhardened parts of the photosensitive agent in microcapsules of the photosensitive material subjected to selective exposure are crushed to form a copied image based on prescribed coloring matters or coloring matter precursors incorporated in crushed microcapsules. Thus, the whole of the device is miniaturized and the weight of the device can be reduced.

Abstract: PURPOSE:To obtain a small sized and inexpensive device capable for rewriting by storing tentatively an input picture by a laser beam to a picture tentative storage medium comprised of a thermal write liquid crystal and recording or exposing it onto photosensing paper or a screen for exposure. CONSTITUTION:The laser beam is modulated by an input picture signal SV fed to a terminal 6, led to an XY terminal system 7 and scanned synchronously with an input picture signal SV based on a drive signal outputted from an XY drive system 8. The tentative storage medium 20 consists of the thermo write liquid crystal 21 and when the laser beam is irradiated the part is opaque locally and the input picture information itself is stored as the contrast in the medium 20. After the information of one screen's content is stored and the exposure light source is irradiated from the glass 25, the picture information stored in the medium 20 is exposed on photosensitive paper 30 to complete the hard copy of input picture. Since write/erasure is attained freely and a near infrared-ray is also used for the laser beam, small size and the low cost are attained.

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 obtain a color image by one exposure process by using a photosensitive material equipped with many microcapsules containing light sensitizers which sense light in a 1st - a 3rd wavelength ranges to cure and corresponding coloring materials, and a beam index type color cathode-ray tube. CONSTITUTION:The sheet type photosensitive material 30 has a surface formed by mixing dispersedly three kinds of many microcapsules (a)-(c) a 1st - a 3rd light sensitizers which are exposed to light in the 1st - the 3rd wavelength ranges to cure and a 1st - a 3rd coloring materials. An image displayed on an index tube 8 which displays the light in the 1st - the 3rd wavelength ranges is used as an exposure light source for the photosensitive material 30, and the exposure process wherein the light in the 1st - the 3rd wavelength ranges is projected to cure the 1st - the 3rd light sensitizers in the three kinds of microcapsules selectively is performed once. The index tube 8 which is high in the utilization rate of an electron beam for fluorescent material excitation is used. Consequently, sufficient exposure intensity is obtained.

Abstract: PURPOSE:To constitute a small-sized developing device with a low cost and to prevent the degradation in quality of an image by moving a roll to scan a photosensitive material and a developing material and providing an angle between the scanning direction of an exposure beam to the feeding direction of the photosensitive material and the moving direction of the roll. CONSTITUTION:A pressurizing means which presses a photosensitive material 2 and a developing material 4 to each other consists of a stage 5 and rolls 6 and 6' which are rotated and moved in the direction crossing the feeding direction of the photosensitive material 2 and the developing material 4 while holding the photosensitive material and the developing material between themselves to press them to the stage 5. An angle theta is provided between the scanning direction of an arrow V to the photosensitive material 2 and the developing material 4 of rolls 6 and 6' and the direction of the extension of an exposure line K to the photosensitive material 2. Thus, the developing device is made small-sized and low-cost and has a structure easy to assemble and maintain, and the degradation in image quality due to disaccord between the direction of the exposure line and that of the pressure line is reduced.

Abstract: PURPOSE:To miniaturize the developing device, and also, to reduce its cost, and to facilitate its assembly and maintenance by supporting plural rollers for pressing a photosensitive film and developing paper by one moving body by shifting each position. CONSTITUTION:Pressure rollers 58, 58' are supported by a supporting arm 53 of a moving block 39, etc., positioned at a small interval and also, in a shifted state, and the shift quantity is set to a prescribed value against width (w) of outside peripheral surfaces 58a, 58'a. In this state, a photosensitive film 63 on which an image is formed is superposed on developing paper 65 and supplied onto a stage 7. As a result, a block 39 moves, and the rollers 58, 58' scan in the right and left directions in a state that the film 63 and the paper 65 are pressed against the upper face 7a of the stage 7, and brought to press- contacting so that the respective scanning loci 69, 69' are overlapped partially. When the block 39 advances to the other end, a sensor provides an output and the film 63 and the paper 65 advance by a prescribed pitch, and the block 39 moves. Such an operation is repeated, and the image is transferred onto the paper 65.

Abstract: PURPOSE:To prevent mis-registration between two sheet materials by constituting the title device in such a manner that the sheet material having the higher rigidity of the two sheet materials is run while said sheet is brought into contact with a stage. CONSTITUTION:The two sheet materials 65, 67 which are different in rigidity are held superposed on each other and are run in this state on the stage 7. The two sheet materials 65, 67 are brought into pressurized contact with each other by rollers 58, 58' which roll in the direction intersecting with the traveling direction of the two sheet materials and the stage 7; in addition, the device is so constituted that the sheet material 65 having the higher rigidity of the two sheet materials is run in the state of maintaining the contact with the stage. The sheet material 65 having the higher rigidity is thus brought into contact with the stage 7 at the time when said material is brought into pressurized contact with the stage by the rollers 58, 58' and, therefore, the generation of such a deformation as to accumulate the repulsive force to induce the parting between said sheet material and the sheet material 67 having the lower rigidity is obviated. The generation of the mis-registration between the two sheet materials is thereby prevented.
