Description

DETAILED DESCRIPTION OF THE INVENTION (Industrial Field of Application) The present invention relates to an image recording device that obtains color hard copies using an optical fiber tube or the like.

(Prior Art) As an image recording device using an optical fiber tube, the one shown in FIG. 1 is conventionally known. This device uses a charging electrode 2 to uniformly charge a photoreceptor drum 1 whose surface is made of 3c or CdS, which is a highly insulating photo-S electric material, and then uses an optical fiber tube 3 to charge the photoreceptor drum 1. An electrostatic latent image is formed by exposing the drum 1, and a developing device 4 is applied to the electrostatic latent image.
The toner image is applied to the toner image by a transfer pole 5, the toner image is transferred onto a transfer paper 6 by a transfer pole 5, and the toner image is fixed by a fixing device 7. This device provides a video signal to the optical fiber tube and a deflection signal to the deflection coil.
Since an electrostatic latent image is formed, the bidet 7I signal can be recorded relatively easily, but there is a problem in that only a black and white hard copy can be obtained as an image, and a color hard copy cannot be obtained.

Meanwhile, blue and green can be used as phosphors in optical fiber tubes.

A recording tube has been proposed that uses phosphors of three colors of red and attempts to scan the bright spots of multiple colors by coating them in a stripe pattern (Japanese Patent Laid-Open No. 01355-66843).
issue). However, in the case of this recording tube, colors are mixed at the boundaries of the coating areas of the phosphors of multiple colors, making it impossible to actually perform bright spot scanning in a predetermined color. It has to be provided correspondingly, and it has not yet been put into practical use.

Under these circumstances, when obtaining a color hard copy, a method of viewing a color image on a CRT screen using, for example, a land camera manufactured by Volaroid Corporation 0 is widely used. This Polaroid photography method involves exposing a negative film coated with a photosensitive emulsion to light, and then bringing the negative film into close contact with a specially treated transfer positive hole, which is not itself photosensitive. The silver oxide emulsion is transferred to the receiving layer of the transfer positive paper and fixed by reduction, so that a positive image can be obtained immediately after photographing. However, the land film has a poor resolution of 2 to 3 lines/mm, and the density is not very good, so conventional development,
Compared to silver halide color film, which is blued through processes such as stopping and fixing, it has a problem of poor quality. Also, these 4
In the case of 14 composition, the composition is also 211, such as requiring color 〇 R number.

Of course, color C can be captured using a regular camera using silver halide film.
There is also a way to take a picture of the R1- screen, but in this case,
Since a color hard copy is output through wet processing such as development, stopping, and fixing, there are problems in that a large amount of processing time is required and the processing apparatus becomes large.

(Objectives of the Invention) The present invention has been made in view of the above-mentioned problems, and its object is to realize an image recording device that can quickly output high-precision, multi-gradation color hard copies.

(Structure of the Invention) The image recording apparatus of the present invention that achieves this object scans and exposes a diffusion transfer photosensitive material with light of three primary colors of blue, green, and red obtained by separating the colors of the original image. The apparatus is characterized by comprising an exposure means and a processing section that performs processing such as development and transfer of the diffusion transfer photosensitive material subjected to the exposure scan.

The diffusion transfer vJril referred to here is, for example, constructed as an instant type film. (dye-relea
The silver halide in the exposed area is not developed because it is a reversal emulsion, but the silver halide in the unexposed area is reduced by the developer, and at the same time the developing agent is oxidized, and this oxidation product Due to the action of dye and alkali, the dye is released from the dye releaser, the diffusible dye is diffused and transferred to the image-receiving layer, and combines with the chelate compound in the image-receiving layer to form a positive dye image.

(Example) Hereinafter, an example of the present invention will be described in detail with reference to the drawings.

In this embodiment, the film is absorbed by the film transport drum 14 and sent from the film stocker 15 to the processing section 16 via the optical fiber tube 11 (near the exposure section). In this section, the Ic developer container 18 containing the developer 17 and the [l-

FIG. 4 shows a specific example of the configuration of this control section 22. In the figure, 31, 32, and 33 are, for example, successive approximation type A/D converters that produce color signals @ (video signal ) into digital signals at high speed. Also, 34.35°36 is the A/D converter 31, respectively.

Note that the film transport path until the film 13 and the image receiving paper 21 are pressed together is shielded from light from the outside.

Next, the operation of the image recording apparatus will be explained.

First, blue, green, and red color signals given from an external device such as a video camera are A/D converted by A/D converters 31 to 33 and stored in memories 34 to 35 for one screen. next,
The blue color signal is read out from the memory 34h) and applied to the D/A converter 37 via the signal processing circuit 38, where it is D/A converted and applied to the optical fiber tube 11. At this time, the deflection circuit 40 applies deflection so that the electron beam scans the blue color filter 11b portion on the tube surface. Now, the spot diameter of the electron beam is 100 μm, and the color filter 11
If the widths of b, 11c, and 11d are approximately the same and are 100 μm, then the film 13 is fed by 100 μm using a conveying means such as a pulse motor, and the green color signal is read out from the dial 35. Similarly to C, the electron beam is emitted. green color filter 11
Expose by applying deflection so as to scan 0. Furthermore, the film 13 is then fed by 100 μrn ]fFJ, and this time the red color signal is read out from the memory 36 and exposed while being deflected so as to skim the color filter 11d.

Through the above three exposures, the same line on the film 13 is the stomach,
This means that the subject was exposed to three colors of light: green and red. Therefore, one line of color signals is recorded on the film 13 according to the principle of the additive color method. When this operation is repeated for one screen, a color screen similar to the original image is formed on the film 13.

When the width of the color filters 1lb, 11c, and 11d is not 100 μm' but 1nII11, for example, the width is performed as follows. First, the color blue (Fi@1
The electron beam (the diameter of which is 100 μm) is read out from the memory 34 and exposed to the electron beam in a sequential scanning manner from the edge of the film 13. When this is completed, the film 13 is conveyed once by 1 mm, 10 lines of the green color signal are read out from the memory 35, and the portion exposed to the blue component is exposed. By repeating exposure for red in the same manner and performing this over the entire surface, a color screen will be formed on the film 13.

The film 133 exposed as described above is immersed in the developing container 18 for about 20 seconds, and then is pressed onto the image receiving paper 21 by the roller 19 and left for about 7 minutes to be deposited on the image receiving paper 21. A full color screen appears. That is, a color hard copy is obtained. This photo is S* compared to the one using the land film mentioned above.
It has excellent color reproduction and color reproducibility, and is of the same quality as general silver halide color film.

In the above explanation, it was stated that it takes about 7 minutes for transfer, but due to improvements in photosensitive materials, this has been reduced to about 9.9 minutes for about 1 minute.
