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
(Rays, electron beams, ultraviolet rays, etc.), a part of this radiation energy is accumulated, and after irradiation with excitation light such as visible light, a phosphor that emits stimulated emission according to the accumulated energy is referred to. This stimulable phosphor is usually formed into a sheet and used as a stimulable phosphor sheet.

In the above system, 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 reading are provided. 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 unit, and the stimulable phosphor sheet is read via the sheet conveying means. Transported to the department. The stimulable phosphor sheet on which the reading section has performed the reading processing of the radiation image information is stored in a cassette disposed in the loading section after the afterimage is deleted in the erasing section.

Advantageously, the structure of the lid opening means is effectively simplified, and the work of taking out the stimulable phosphor sheet or the photographic photosensitive material (hereinafter, referred to as a sheet body) by the sheet-by-sheet means is quickly and easily performed. Because there is.

However, when the container is loaded into the loading portion, the container may be pushed in vigorously, and there is a problem that the sheet body jumps out of the container due to its inertia.

Further, for example, in a processing apparatus having a loading portion capable of loading a plurality of containers, after the sheet body sheet moving means moves in correspondence with an arbitrary loading portion, the sheet member is moved from the container disposed in the loading portion. The sheet has been removed. However, if the sheet body jumps out of the container loaded in each loading section, the sheet body interferes when the sheet body sheet feeding means is moved to an arbitrary loading section, and the sheet work of the sheet body becomes efficient. It has been pointed out that the problem is not achieved.

The present invention solves this kind of problem, and when a container is loaded in a loading section, the sheet body is reliably prevented from unnecessarily jumping out of the container.

Thus, even if the container is loaded into the loading portion with force, the sheet body can be reliably prevented from jumping out of the container under the action of the stopper means. In addition, the stopper means can be moved forward and backward with a mechanical structure, and the structure can be simplified.

[0013] Further, a stopper means is fixed to the loading portion, a swing frame supported by the fixed frame so as to be swingable, and rotatably mounted on the swing frame via an elastic body. The sheet body is arranged on the take-out locus of the sheet body in a state of being engaged with the fixed frame, and is arranged outside the take-out locus of the sheet body in a state of being detached from the fixed frame under the pressing action of the first operating means. And a plate-shaped locking member. Therefore, the sheet-by-sheet work of the sheet body can be efficiently and reliably performed with a simple configuration.

Furthermore, a second operating means projects through the elastic body to the container side and is capable of moving forward and backward under the pressing action of the container, and an arm which is engaged with the contact member and is swingable. And a pressing portion provided on the arm member, for urging the swing frame toward the fixed frame side when the container is detached from the abutting member to engage the plate member with the fixed frame. .
For this reason, only by pulling out the container from the loading section, the plate-shaped locking member can be automatically and reliably arranged on the locus of taking out the sheet member.

Further, in the present invention, the loading section is provided with stopper means located in front of the container in the loading direction, and the stopper means comprises a locking member capable of abutting on the sheet member and the locking member. And an actuator for displacing the sheet member on a take-out locus of the sheet member and outside the take-out locus. This makes it possible to reliably prevent the sheet body from jumping out of the container, and to simplify the configuration.

Further, according to the present invention, the apparatus is incorporated in a sheet loading apparatus having a plurality of loading sections for detachably loading a plurality of containers, and a movable sheet moving relative to any of the loading sections. Stopper means is interlocked with the movement of the movable sheet unit, and allows the sheet body to be taken out from the loading unit in which the movable sheet unit is arranged, while allowing the other sheet unit to remove the sheet body. The sheet taking-out operation is regulated. Therefore, it is possible to effectively prevent the sheet body from jumping out of each container loaded in the loading section in which the movable sheet portion is not arranged.

At this time, the stopper means may be a long body whose both ends are fixed with a gap capable of inserting the sheet member into the movable sheet portion, or a stopper having one end fixed to the movable sheet portion and the other end fixed. First and second elongated bodies are provided that can be wound and accommodated in the first and second winding members via an elastic body. For this reason, an unnecessary protrusion of the sheet body can be reliably prevented with a very simple configuration. The long body includes, for example, a wire, a belt, a tape, or the like.
