て診断に供することのできる画質となって表示される。(Prior Art and its Problems) Most medical images are displayed on radiographic films, and various diseases are diagnosed from the findings on the images. Radiographic images are displayed with image quality suitable for diagnosis only when a series of devices such as radiographic equipment, radiation film, and automatic processors operate smoothly.

化の一例を第２図に示す。The problem in the process of forming radiographic images is that it is difficult to make a diagnosis.
Static electricity is generated during the process of completing an image, that is, during the operation of radiographic film, and when image quality deteriorates due to this static electricity, it is necessary to make a correct diagnosis and quickly set the correct treatment plan. It is often a huge obstacle in doing so. - In this example, the frequency of occurrence of image quality deterioration due to static electricity generation is as high as 5 to 15% of all photographed examples, and the intensity of static electricity is said to be 5000 to 6000 volts. An example of this image quality deterioration is shown in FIG.
第２図（ａ）では胸部エックス線画像に樹枝状の劣化ａ

するものとはいえない。Conventionally, methods for improving the image quality of this building include coating the inside of the cassette or magazine with an anti-static agent such as a so-called screen cleaner9, or adding a brush to the film passage process. There are ways to prevent this problem, but none of them can be said to be a fundamental solution.
本発明はかかる問題点を解決することを目的とするもの
である。The present invention aims to solve such problems.

テープあるいは薄い銅線等を貼布する等して構成する。In this configuration, the film loading N11 is, for example, the film contacting side 2 of the top plate 5 (64) in the case of a cassette, and the raw film magazine (not shown) and the receiving magazine (not shown) in the case of an autocassette. In addition, the conductor 3 is arranged in a frame shape around the periphery of the film contacting side 2, avoiding the central part of the film contacting side 2, so as not to interfere with photography or film loading. It is constructed by pasting conductive plastic tape or thin copper wire.
また、第１図のカセツテの例では、導電体３は表板５の
フィルム当接側２にのみ構成しているが、晟ぶた６のフ
ィルム当接側にも設けてよいのはもちろんである。Further, in the example of the cassette shown in FIG. 1, the conductor 3 is provided only on the film contacting side 2 of the top plate 5, but it is of course possible to provide it on the film contacting side of the lid 6 as well. .

の画質劣化を効果的に抑止することができる。(Function) With the above configuration, static electricity generated between the film and the film loading unit 1 due to friction when loading or removing the film from the film loading unit 1 is discharged into the four electric bodies 3 at each station. Therefore, deterioration of image quality of the film due to electrostatic discharge can be effectively suppressed.

るという効果がある。In other words, radiation film is usually made of thin polyester coated with silver, and the film is placed in the film loading section 1.
When loading or unloading the film, electricity is generated between the film and the film loading section 1 due to friction, and this discharge causes image quality deterioration such as dendrites, which is particularly noticeable in winter when the air is dry. be. The present invention prevents image quality deterioration caused by such static electricity, and by configuring the conductor 3 in a frame shape at the periphery of the film contacting side 2 of the film loading section 1, charges are transferred to the periphery. Therefore, the equipotential area suppresses the generation of a local high potential difference due to static electricity on the film contact side 2, and the conductor 3 Since it becomes a good discharge path for the electric charge charged in the film loading section 1, the electric charge is relaxed and discharge is suppressed, so that deterioration of image quality can be prevented.
Effects of the Invention) As described above, the present invention can be easily configured into a ready-made cassette or an automatic cassette, so the cost is low and the system is simple.
Since it is possible to effectively prevent the deterioration of image quality caused by 1. It has a large effect. In addition, since there is no deterioration in image quality due to the generation of static electricity, there is no need for re-imaging, which reduces the burden on patients, doctors, and technicians, and improves the efficiency of imaging-related work.
