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 expose images of any gradation with simple constitution by light- emitting the number of horizontal scan lines according to the gradation detected by a gradation detecting device by means of interlocking with travel of a photosensitive material by a traveling device. CONSTITUTION:Exposing video signals for still images are supplied to an input terminal 11, and are stored in a frame memory 14. Gradation signals of three bits, for example, are stored in the memory 14 in one-picture element units. When these signals are read out of the memory 14, synchronizing signals for reading are supplied to the memory 14 from a controller 13 through a picture element counter 15 and a line counter 16, and the gradation signals are read out of the memory 14 to a comparator 17. The sequence to read out the horizontal scan lines is as follows: five horizontal scan lines are read during one vertical scanning period, then five horizontal scan lines, one of which is shifted, are read out during a next horizontal scanning period. The comparator 17 compares bit signals indicating the gradation of the read-out horizontal scan lines with count signals indicating displayed lines in one-picture element units, and when the bit signals indicating gradation are larger, signals turning on each picture element scanning period are output to perform exposure.

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 reproduced image equipped with sufficient resolving power and good medium contrast, by controlling an electron beam spot performing dot beam emission on a fluorescent surface on the basis of an image signal. CONSTITUTION:In an image signal forming part 4, the image Sp formed in accordance with the image on a manuscript 2 is supplied to a beam control circuit part 6. The control circuit part 6 generates beam control voltage signals Sg1, Sg2 to supply the same to the electron gun structure at the neck part 12 of a cathode ray tube 8 and the display of an image due to dot beam emission is performed on a screen panel part 10 by the electron beam scanning a fluorescent surface 11. At this time, each dot beam emitting part in the panel part 10 comes to have almost constant brightness such that the diameter thereof is like each of Pa, Pb, Pc corresponding to the level of the image signal Sp. Therefore, in a photosensitive sheet 20, the non-exposure part in each image unit corresponds to each of the beam non-emitting parts W1, W2, W3 in the panel part 10. That is, the medium contrast corresponding to the level of the image signal Sp and sufficient resolving power are provided.

Abstract: PURPOSE:To obtain 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 and entering ultraviolet rays into the space. CONSTITUTION:Plural control electrodes 1 are provided in a transparent case 3, a common electrode 5 is arranged below it across the space 14, and the particulate 6 which cuts off ultraviolet rays and has 10 -10 OMEGA.cm is put in the groove of the electrode 5. A DC voltage DV is applied corresponding to the image signal of a voltage supplying control part 8 to establish an electric field between the electrodes 1 and 5 and the particulate 6 moves between the electrodes 1 and 5 to form an image pattern. Ultraviolet rays from a ultraviolet rays source 15 passes through the space 14 and photosensitive paper 17 is exposed to them, but the ultraviolet rays are cut off by the particulate 6. Thus, the ultraviolet rays are easily controlled and an image of good quality with superior resolution is formed on the photosensitive paper.

Abstract: PURPOSE:To obtain a good quality image with high resolution and comparatively simple constitution, by heating selectively each of plural heating resistors in accordance with an image signal, and controlling the arrival state of an ultraviolet ray while displacing selectively a movable part of plural thermal deforming members. CONSTITUTION:A supporting plate member 35 is moved by a feed screw mechanism 36, and a prescribed position of a sensitized paper 32 which has been supported by the supporting plate member 35 is opposed to a slit window part 20a provided on an ultraviolet ray cut-off member 20. An ultraviolet light source 34 is lighted, and an exposure is executed through the slit window part 20a by an ultraviolet ray from the ultraviolet light source 34 to the sensitized paper 32 which has been supported by the supporting plate member 35. On the sensitized paper 32, an exposure pattern containing a non-exposure part corresponding to a position of a thermal deforming member 11 which has been selected in accordance with an image signal Sv is formed, and an image of one scanning line portion based on the image signal Sv is transferred. In such way, an image with high resolution and good quality can be obtained on a photosensitive member.
