Description

Detailed Description of the Invention [Field of Industrial Application] The present invention uses a photosensitive material coated with a substance to which an image obtained by imagewise exposure is fixed by pressure. The present invention relates to an image recording device in which a latent image obtained by exposure is thermally developed and fixed by pressure.

[Technical background of the invention and its problems]

As an example of an image recording material using microcapsules encapsulating a photosensitive composition, for example, Japanese Patent Application Laid-Open No. 57-1798
A system is known that carries a synthetic polymer resin-walled capsule containing a vinyl compound as a support, a photoinitiator, and a colorant precursor, as disclosed in Publication No. 56. An image recording method using this system is to harden the microcassette in the absence of light, rupture the unhardened microcapsule under pressure, and obtain a color image from the released colorant tricaser. The method is characterized in that high quality images can be obtained through simple dry processing.

However, this system has the drawback of significantly lower photosensitivity than systems using silver halide.

A new recording material that improves these drawbacks, has high photosensitivity, and can obtain high-quality images through a simple dry process9 has been proposed in Japanese Patent Application No. 1986-1999 filed by the present applicant.
- Disclosed in the specification of No. 117089. This recording material has a support coated with a photosensitive silver halide, a reducing agent, a polymerizable compound, and a color image-forming substance, and at least microcapsules containing the polymerizable compound and the color image-forming substance. A photosensitive composition is encapsulated in a photosensitive composition.

Regarding the image recording method of recording images using this photosensitive material, Japanese Patent Application No. 60-1212 filed by the present applicant
It is disclosed in the specification of No. 84.

This image recording method first performs imagewise exposure to form a latent image, then develops it by heating, and polymerizes the polymerizable compound in the area where the latent image exists to form a macromolecular compound to form microcapsules. harden. The image-receiving material is overlapped with an image-receiving material having an image-receiving layer to which the color image-forming substance can be transferred, and at least a portion of the microcapsules in the area where the latent image does not exist is ruptured, thereby transferring the color image-forming substance to the image-receiving material. to obtain an image on an image-receiving material.

Then, using the above-mentioned photosensitive material, this photosensitive material is subjected to imagewise exposure, heat development is performed, and then the image-receiving material is superimposed and pressed, and the next image is obtained by transfer to the image-receiving material. Image recording is performed automatically. The apparatus is disclosed, for example, in Japanese Patent Application No. 51896/1989 filed by the present applicant.

Here, since the temperature inside the heat developing device is high, the heat developing device is surrounded by a heat insulating material so as not to affect other parts of the image recording device.

However, since the photosensitive material inlet and outlet of the heat developing device cannot be made airtight, complete insulation cannot be achieved. When the conveyance distance of the photosensitive material between the exposure section and the heat developing device is shortened, the photosensitive material inlet of the heat developing device inevitably opens in the upward direction 'VC' near the exposure section. In such a case, the temperature of the non-light area and other devices above the ship's thermal developing device rises due to the high temperature hot air flowing upward from the photosensitive material inlet K and the outlet. When a photosensitive material before exposure or development is transported through the heated apparatus, image quality deteriorates. It also has a negative effect on electrical parts and optical systems. Furthermore, there is a problem in that the heat retention efficiency of the heat developing device naturally decreases, and the energy consumption for temperature control increases.

[Purpose of the invention]

SUMMARY OF THE INVENTION An object of the present invention is to solve the above-mentioned problems, and to provide an image recording apparatus that is less susceptible to the effects of high-temperature hot air flowing out from a heat developing device.

[Means to solve the problem]

The apparatus of the present invention achieves the above-mentioned purpose by performing heat development on a photosensitive material on which a support is coated with a substance that fixes the image produced by imagewise exposure under pressure, thereby transferring an image onto an image-receiving material. An image recording device that performs pressure transfer, and has a heat developing device equipped with a photosensitive material inlet and a photosensitive material outlet, and the normal line of the opening surface of the inlet and outlet is in the horizontal direction or from the horizontal direction. This problem is solved by a configuration that points downward.

That is, by orienting the photosensitive material inlet and outlet of the heat developing device in the horizontal direction or below the horizontal direction, the heat development g1. It is possible to reduce the upward flow of high-temperature hot air inside the equipment, increase heat retention efficiency, and prevent the unit above the heat developing device from rising in temperature due to the hot air.

In the present invention, the photosensitive material refers to a material for obtaining a visible image by applying pressure to a latent image generated by imagewise exposure.

An example of such a material is a type of material in which a polymerizable compound is imagewise cured by imagewise exposure, and then a visible image is obtained by applying pressure, as disclosed in Japanese Patent Application Laid-Open No. 57-1991 filed by the present applicant. The material disclosed in Japanese Patent No. 179836 is mentioned. This material has a synthetic polymer resin wall capsule containing a vinyl compound, a photopolymerization initiator, and a colorant precursor supported on a support.

Alternatively, after containing silver halide and giving imagewise exposure, heat development is performed to develop the silver halide, the polymerizable compound is simultaneously cured in correspondence with this development, and then pressure is applied to form a visible image. An example of the type of material that can be obtained is the material disclosed in Japanese Patent Application No. 121284/1984 filed by the present applicant.

The material disclosed in the above-mentioned Japanese Patent Application No. 121284/1984 is
After thermal development, a color image-forming substance is transferred to an image-receiving material having an image-receiving layer to obtain an image on the image-receiving material. At least a photosensitive silver halide, a reducing agent, a polymerizable compound, and In some cases, a color image-forming substance is coated, and at least the polymerizable compound and the color image-forming substance are encapsulated in the same microcapsule.

The image recording apparatus according to the present invention is of five types, and means one having a heat developing device.
