がある。According to this proposal, in the space illuminated by light from the light source,
By arranging the original and the thermal recording paper and driving the light source with them aligned, thermal energy is generated by light absorption/thermal conversion in the image area drawn on the original, and this thermal energy is used to generate thermal energy.

ロース、ポリビニルアルコール等が好ましい。The self-recording layer 6B is made of a material that is highly thermochromic and photofixable. That is, the recording i6B contains a diazonium salt, a coupler, a basic compound, a heat sensitizer, and a binder as basic components. In order to ensure photofixing by exposure, which is dry and easy to operate, it is necessary for the reaction component to have photosensitivity and lose photoreactivity after exposure. In this example, the photoreaction system is a diazonium salt. This is done by a combination of and a coupler (thermal development diazo method). Both components undergo a diazo coupling reaction in a salty atmosphere to form an azo dye and produce an azo dye image. This azo dye image has good stability, unlike the case of paint-colored thermosensitive recording paper using leuco dye, and the recorded image is less likely to fade due to adhesive tape or the like. Furthermore, diazonium salts are photodecomposed by exposure to light and become phenolic compounds that do not have coupling ability. As the diazonium salt, diazo TPB salts with small water bathing properties, which are convenient for coating in a water dispersion system, are preferable.
Examples of couplers include naphthol dye couplers and couplers having a morpholino group, which is a basic residue. β-S7-AI derivatives are mainly used as a blue coloring system. In the case of a black coloring system, it is customary to incorporate a yellow coloring thread, acetoacedoide = IJ compound, having an active methylene group. On the other hand, the basic compound has the role of a substance that makes the inside of the system a basic atmosphere during heating, and it is most effective to use a heat bath decomposable base as this material. The heat sensitizer is a material necessary to improve heat sensitivity, and for example, naphthol derivatives are preferred. As the binder, vinyl chloride copolymer, polyester, polyurethane, acrylate coelectrolyte, ethyl cellulose, polyvinyl alcohol, etc. are preferable.

A pressure-sensitive mechanism (not shown) provided on the side of the light storage case 1 operates and a trigger signal is applied to the lighting circuit, whereby the lighting circuit is stored in the photoelectric circuit in the photoelectric device.
The charge is discharged, and a drive voltage suitable for closed lighting is first applied to the infrared irradiation lamp 3A. As a result, the lamp 3A automatically closes, and the light passes through the transparent plate 11 and the heat-sensitive recording paper 6 and is irradiated onto the original 5.

Then, due to this thermal energy, the inside of the system of the corresponding recording area 1d of the thermosensitive recording paper 6 becomes a basic atmosphere due to the basic compound that changes with the heat sensitivity, and as a result, a diazo coupling reaction occurs between the diazonium salt and the carpler. , a predetermined azo dye image is obtained on the base layer 6A, and as a result, a mirror image copy a according to the image area 15 of the original 5 is formed.

The ultraviolet irradiation lamp 3B is automatically brightened to illuminate the entire surface of the original 5 under a predetermined short length of light. Then, the unrecorded portion (the remaining diazonium salt portion) is photodecomposed, the unreacted diazonium salt is inactivated, and the photofixing is carried out. In the above case, in order to match the absorption wavelength of the light beam from the UV irradiation lamp 3B with the absorption wavelength of the vL long distribution diazonium salt and to improve the light fixing sensitivity, the wavelength of the light beam from the lamp 3B is adjusted. It is most effective to adjust the distribution to a diazonium salt spectroscopic wavelength device (usually having a peak at 370 to 4200).

This is done by photolyzing the remaining (unreacted) diazonium salt based on the photodecomposition effect caused by ultraviolet irradiation from the ultraviolet irradiation lamp 3B, so even if it is reheated after thermal recording. Therefore, it is possible to prevent the unrecorded portion from becoming colored, and therefore valuable data can be stored for a long period of time.

This is done by photodecomposing the diazonium salt in the unrecorded area due to the photodecomposition effect of light, so even if reheating is performed after recording,
