Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a cassette for storing a stimulable phosphor sheet having various kinds of ID information while accommodating the stimulable phosphor sheet, and the ID information when the cassette is loaded into a loading device. The present invention relates to an ID recognition structure of a stimulable phosphor sheet cassette to be recognized.

[0002]

2. Description of the Related Art For example, stimulable phosphors (stimulable phosphors)
There is known a system that once records radiation image information of a subject such as a human body, reproduces the radiation image information on a photographic photosensitive material such as a photographic film, or outputs a visible image on a CRT or the like. I have.

The stimulable phosphor is composed of radiation (X-ray, α-ray, γ
(E.g., a beam, an electron beam, or an ultraviolet ray), a part of the radiation energy is accumulated, and a phosphor that emits stimulated light in response to the accumulated energy when irradiated with excitation light such as visible light. This stimulable phosphor is usually formed into a sheet and used as a stimulable phosphor sheet.

[0004] The above system includes, for example, a reading section for reading image information recorded on the stimulable phosphor sheet, and an erasing section for erasing image information remaining on the stimulable phosphor sheet after the reading. An image information reading device is employed. In this image information reading apparatus, a cassette accommodating a stimulable phosphor sheet on which radiation image information of a subject is recorded by an external photographing device is inserted into a loading section.

[0005] Next, with the cassette opened, the stimulable phosphor sheet is taken out of the cassette under the action of the sheet body sheet means, and the stimulable phosphor sheet is read through the sheet body conveying means. Transported to the department. The stimulable phosphor sheet on which the reading unit has performed the reading processing of the radiation image information is stored in a cassette disposed in the loading unit after the afterimage is deleted in the erasing unit.

[0006] This kind of stimulable phosphor sheet is usually constituted by providing a phosphor layer (recording surface) on an opaque base surface. For this reason, the reading unit includes an excitation light irradiating unit that irradiates the phosphor layer with excitation light, and a condensing unit that collects stimulated emission light emitted from the phosphor layer by the irradiation of the excitation light. In addition to the arrangement, the erasing section is provided with an erasing light source for irradiating erasing light from the phosphor layer side.

[0007]

However, recently, in order to reproduce radiation image information of a subject with high image quality, such as in mammography, it is necessary to efficiently read the energy stored in the stimulable phosphor sheet. It has been desired to make the base surface of the stimulable phosphor sheet transparent. In the stimulable phosphor sheet, when excitation light is irradiated from the phosphor layer side, stimulated emission light is emitted not only from the phosphor layer side but also from the base surface side (back surface side). Therefore, in the reading section, two light collecting means for collecting the stimulated emission light are provided on both sides of the stimulable phosphor sheet.
On the other hand, the erasing section is configured to irradiate irradiation light from the phosphor layer side of the stimulable phosphor sheet.

As described above, the stimulable phosphor sheet emits stimulable luminescent light from the recording surface (phosphor layer) side and stimulable luminescent light from both the recording surface and the base surface. It has a double-sided sheet body, but it has been pointed out that the double-sided sheet body cannot be recognized in the image information reading apparatus. As in the case of the single-sided sheet body, when a barcode is attached to the base surface of the double-sided sheet body, irradiation light for reading the barcode passes through the base surface, and the recording surface may be exposed. The stimulating light emitted by the light irradiation may be interrupted by the bar code, which may cause trouble in reading.

The present invention solves this kind of problem, and can reliably display the ID information of the stimulable phosphor sheet housed in the cassette and is excellent in versatility. The purpose is to provide a cassette for use.

Further, the present invention provides a stimulable phosphor sheet capable of reliably recognizing ID information of a stimulable phosphor sheet contained in a cassette when the cassette is loaded into a loading device. It is an object of the present invention to provide an ID recognition structure of a cassette.

[0011]

According to the present invention, ID information is provided via first ID display means used by a user to register ID information on the outer surface of a cassette, and a device into which the cassette is loaded. The second ID used to read
Display means is provided. For this reason, when the cassette is loaded in the loading device, the ID information of the stimulable phosphor sheet contained in the cassette can be read, and appropriate processing according to the type of the stimulable phosphor sheet can be performed. Can be applied.

Here, the second ID display means is disposed at a predetermined portion of the positioning reference surface of the cassette or at a portion separated from the reference surface by a certain distance in the width direction. Therefore, even when cassettes having various dimensions are used, the second ID display means provided on each cassette is always arranged at a fixed position in a state where the cassette is loaded in the loading device. become. This makes it possible to easily and reliably read the second ID display means via the reading means provided in the loading device, resulting in excellent versatility.

In the second ID display means, information for identifying whether the stimulable phosphor sheet is a single-sided sheet or a double-sided sheet is recorded. Therefore, the ID information of the double-sided sheet body to which the ID display means such as a barcode is not directly attached is stored in the cassette accommodating the same.
It is possible to load a single-sided sheet body and a double-sided sheet body into a loading device by using the cassette having a simple configuration provided as ID display means. This allows
When a cassette accommodating a variety of different stimulable phosphor sheets is loaded into the loading device, the information on the stimulable phosphor sheet is read through reading means provided in the loading device.
The D information is reliably read, and the ID recognition processing is efficiently performed.

Further, cushioning materials are provided on the inner wall surface of the cassette so as to correspond to both sides of the stimulable phosphor sheet. For this reason, the stimulable phosphor sheet is not damaged in the cassette to generate debris and the like, and it is possible to prevent the debris from being brought into the loading device. In particular, the base surface of the double-sided sheet body is not damaged, and the stimulated emission light emitted from both sides of the double-sided sheet body is surely condensed, and high-quality reproduction is easily performed.
