BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an instant film for dental use, and more particularly, to an instant film and an instant film for dental X-ray photography in which X-ray photography and development are carried out using an instant film and an X-ray photographing machine. About the machine.

[0002]

2. Description of the Related Art In general, radiographs are used for medical diagnosis, dental diagnosis, and the like. When radiographs are taken, it is necessary to develop, fix, and wash the photographed film. In addition, there were inconveniences such as requiring skill for development processing and further requiring time for development processing. Furthermore, a developer, a fixer,
It requires management such as monitoring the degree of contamination of the water for washing and replacing these liquids with new liquids, which requires time and nerves.

[0003] In view of the above situation, the present applicant has previously proposed to perform X-ray imaging using a film for an instant camera without using a developing machine. This X-ray photography method uses an instant camera, a film for the instant camera, and an X-ray photographing machine. The X-ray photographing machine takes an X-ray photograph of an object to be photographed with the X-ray photographing machine. Developing with the instant camera, or a film for the instant camera,
An X-ray photographing machine is used to perform X-ray photographing of an object to be photographed on the film by the X-ray photographing machine, and the X-ray photographed film is developed.

[0004] When radiography is performed using a dental-size film, generally, as is well known, the film is put into the oral cavity and X-rays are irradiated from the outside to perform radiography. The film has the film in a single cover. Therefore, at the time of development, the handling becomes unsanitary due to saliva or the like attached to the cover.

Further, in the development, as in the case of a commercially available film for an instant camera, a developing solution contained in a bag provided integrally with the film is crushed and the developing solution is flushed onto the film so as to be developed. At that time, the developer was discharged by breaking the bag containing the developer, and an instant camera for development was not required. The X-ray camera and the instant camera were simply configured as described above. X-ray photography and development were possible simply by using a film.

[0006]

SUMMARY OF THE INVENTION When taking an X-ray photograph using an X-ray photographing machine, an instant camera, and a film for the instant camera,
An object to be imaged is placed on a film for an instant camera, an image is taken with an X-ray photographing machine, the imaged film is mounted on an instant camera, and a shutter is released in a state where a lens surface is shielded from light. In this case, when a film for a Polaroid camera currently marketed (for example, a trade name of Nippon Polaroid Co., Ltd.) is used, a set of 10 films is obtained. I take 10 photos at the same time. However, in actuality, since ten identical photographs are not required, if the film is configured so that each film can be used, for example, in a dental treatment or the like, a dental size radiograph can be obtained. It is convenient to take a picture, and in particular, if a dental-size film can be provided exclusively for dentistry, each dental clinic has an X-ray machine, so it is sufficient to simply purchase the film.
