Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a cassette for accommodating a radiation image conversion panel, and more particularly to an improvement in a mounting structure of a lid which covers the entire back surface of the cassette.

[0002]

2. Description of the Related Art An X-ray photographic film has been conventionally known as a recording medium for recording a radiation image of a human body or the like. As a recording medium used for the same purpose, for example, a radiation image conversion panel (or a stimulable phosphor sheet) disclosed in JP-A-55-12429 and JP-A-56-11395,
That is, a radiation image conversion panel having a layer of stimulable phosphor is also known. The above-mentioned stimulable phosphor means that when it is irradiated with radiation (X-rays, α-rays, β-rays, γ-rays, ultraviolet rays, electron beams, etc.), a part of its energy is accumulated and then excitation light such as visible light is irradiated. It is a phosphor that emits stimulated emission depending on the energy stored when it receives the light.

After the radiation image of the subject is photographed or recorded on the radiation image conversion panel by, for example, irradiating the radiation transmitted through the subject, the panel is two-dimensionally scanned with excitation light and emitted from this panel. By photoelectrically detecting the emitted stimulated emission light, an electrical image signal indicating radiation image information can be obtained.

The above-mentioned radiation image conversion panel and X-ray film are usually handled by being housed in a cassette or magazine having a light-shielding property. This cassette accommodates a panel-shaped or sheet-shaped image recording medium such as a radiation image conversion panel one by one, or a sub-number of sheets as needed, and normally, at least part of the recording medium is taken in and out. And a lid body for opening and closing the opening of the main body.
Conventionally, this lid was hinged to one end of the box, and the whole lid was rotated to open the entire back surface of the box. , The space occupied by the cassette with the lid open is large,
Particularly, this cassette is capable of continuously performing a series of operations for recording, reading, and erasing a radiation image, and a radiation image information recording / reading device (Japanese Patent Laid-Open No. 59-192240).
No. 3-238441, etc.), the cassette occupies a space, which causes a problem that the entire apparatus becomes large.

Therefore, the applicant of the present application divides the lid of the cassette into a main portion and an opening / closing portion by the hinged portion as described above, and the main portion is integrated with the main body or by a plurality of fixing means such as screws. A cassette has been proposed, which is fixed to the main body and can be opened and closed only in the opening and closing portion hinged to the main part (see Japanese Patent Laid-Open No. 60-103230).

[0006]

By the way, the above-mentioned cassette for radiation image conversion panel is loaded not only in the radiation image information recording / reading apparatus but also in, for example, the radiation image information recording apparatus for recording only radiation image information. In order to read the recorded information, it may be taken out from this recording device and used for carrying. If you accidentally drop the cassette while carrying it, a part of the cassette may be damaged.In that case, even if the damaged part is a very small part, the light-shielding performance of the cassette will be reduced, so In a cassette in which the body is integrally formed, it is necessary to replace the entire cassette with a new one, and in a cassette in which the main body and the lid are fixed by a large number of fixing means, the main body and the lid It is necessary to disassemble the fixed parts with and one by one and replace the damaged components.

When the inside of the cassette is contaminated due to long-term use and the inside of the cassette is to be cleaned, it is necessary to replace the entire cassette or disassemble the fixed portion as described above.
