DETAILED DESCRIPTION OF THE INVENTION [Technical Field of the Invention] The present invention relates to a recording medium storage container that is included in a radiation diagnostic apparatus and is used to store a radiation recording medium capable of recording radiation images.

[Technical background of the invention and its problems 1 A radiological diagnostic apparatus, for example an X-ray diagnostic apparatus, is shown in FIG. This device consists of an X-ray tube XT for irradiating the subject (patient) with X-rays, a top plate 8T placed below the X-ray tube XT for placing the subject, and a lower part of the top plate. The image system IM includes a spot shot device ST placed in the X-ray tube XT, and an image system IM including an image intensifier that converts the X-rays emitted from the X-ray tube XT and transmitted through the subject into electric radiation.

Note that from the X-ray tube ST, X-rays are emitted to transfer a transmitted image of the subject onto a radiation recording medium, such as a sheet film, and an XIl transmitted image is displayed on a display (not shown) via the image intensifier. 2 with x-ray for
X-rays of different types are irradiated.

The spot shot device 4 is configured as shown in FIG. 7, for example. 1 shows an unshot film storage container (g, bottom, called a feed magazine) that stores unshot sheet films 2, and a plurality of sheet films 2 stored in this feed magazine 1 are placed on the upper side. The suction cup 3, which is movable in the direction of the upper F arrow U-D and the left-right arrow L-R, picks up the films one by one from an opening provided at the top of the feed magazine 1. Take it out. Then, when the suction cup 3 is moved to the position of the pair of transport rollers 4, the sheet film 2 can be held by the transport rollers 4. As a result, the sheet film 2 is sandwiched between the conveying rows 54 and sent between the close contact holders 5 placed open at the standby position 6A.

When the sheet film 2 is fed in, the top lid 5A of the close contact holder 5 closes in the direction of arrow 8 to sandwich the sheet film 2. The camera waits at this standby position 116A until a photographing command is given.

When an imaging command is received, the close contact holder 5 is sent to the m-position, which is the irradiation field position of the X-ray tube XT for the subject on the bed BT, and after the imaging is completed, it is returned to the standby position 1f6A. Here, the close contact holder 5 is opened, and at the same time, the conveyance roller 4 is reversed.

Then, the photographed film in the close contact holder 5 is picked up by the rotating transport rollers 4 and taken out.

At this time, a direction switching plate 8 provided on the exit side of the conveying roller 4 guides the photographed sheet film, which is being fed upward in the direction of arrow E, to a guide 9 with the pivot 8A as a fulcrum. lead to the side.

As a result, the photographed sheet film 2 is guided through the guide 9 and sent to the photographed film storage container (hereinafter referred to as a "tick-up magazine") 10 provided at the bottom of the sheet film 1. The photographed sheet film 2 is folded into the pickup magazine 10 and stored by a folding plate 11 provided nearby and driven in the GH direction.

By the way, the feed magazine 1 and the pick-up magazine 10 have a structure as shown in FIG. That is, the figure shows a side sectional view of the recording medium storage container, in which 21 is a box-shaped main body, and at the longitudinal end of the upper surface there is an opening for taking in and out the sheet film 2 stored inside. 21
a is formed. Moreover, this opening 21afrMf
A sliding door-shaped light-shielding plate 22 that can be opened and closed through the inner surface of the main body 21 is provided on the upper surface side of the main body 21 in order to allow the light-shielding plate 22 to be opened and closed. The light shielding plate 22 is opened and closed by further vibration operation.

Such a recording medium storage container closes the light-shielding plate 22 to keep the sheet film 2 inside in a light-shielded state while the handle portion 2 is closed.
4, the sheet film 2 can be inserted into the spot shot device 4 of the X-ray diagnostic apparatus, and after installation, the light shielding plate 22 can be opened to allow the sheet film 2 to be put in and taken out. Since the sheet film 2 is used only once, there is no need to be concerned about scratches caused by contact between the sheet films, and therefore the recording medium storage container is generally of a partially open type.

In addition, when using a stimulable phosphor sheet (hereinafter referred to as IP) as a radiation recording medium, it is assumed that it will be used many times. A fully open type is adopted.

However, according to the fully open type recording medium storage container, when the bed BT is raised and lowered (±90°) or when the device is moved, the IP stored in the container body 21 is This may cause inconveniences such as scratches or the IP falling down. For example, an IP with a size of 354 ms x 351 m has a tolerance of ±ll1 m, and this is due to this tolerance.

If a scratch occurs on the IP, not only will the recorded information become unreadable, but it will also become impossible to use the IP many times, so there is a strong desire to improve the above-mentioned disadvantages.

[Object of the Invention] The present invention has been made in view of the above circumstances, and its purpose is to prevent scratches caused by contact etc. due to the size tolerance of radiation recording media, and to prevent the bed from being raised. It is an object of the present invention to provide a recording medium storage container that does not cause inconveniences such as radiation recording media falling down due to falling.

[Summary of the Invention] The key point of the present invention to achieve the above object is that a recording medium storage container is constructed by providing a recording medium holding means for holding a radiation recording medium on a part of the inner surface of the container body. This feature is designed to prevent the radiation recording medium from being scratched or falling down.

[Embodiments of the invention] Hereinafter, the present invention will be specifically explained with reference to Examples.

FIG. 1 is a perspective view of a recording medium storage container according to an embodiment of the present invention, and FIG. 2 is a sectional view taken along line Ao-A in FIG.

1 and 2, this recording medium storage container differs from the conventional one in that a recording medium holding means 25 is provided on the inner surface of the container body 21.

Here, the recording medium holding means 25 includes a planar fastener 2 made of a raised material on a flexible member 25a such as foamed plastic.
5b is attached.

Next, the effect of the above configuration will be explained with reference to FIG. 3.

FIG. 3 is an explanatory diagram for explaining the function of the recording medium storage container shown in FIG. 1.

By providing the recording medium holding means 25, when the IP 26 is inserted into the container body 21, the end 2 inserted first
6a and the later-inserted end 26b each advance while pressing against the recording medium holding means 25. However, the recording medium holding means 25 includes a flexible member 25a and a raised material 25b.
Therefore, the IP 26 housed in the container body 21 can be held securely.

As described above, in this embodiment, since the recording medium holding means 25 consisting of the flexible member 25a and the raised material 25b is provided on the inner circumferential side of the container body 21, the IP2
6 tolerance ±11Il■ and 1P26
As a result, there will be no damage to the IP due to contact between the IPs 26, and there will be no inconvenience such as the IP 26 falling down due to the raising and lowering of the bed BT.

Although one embodiment of the present invention has been described above, it goes without saying that the present invention is not limited to the above-mentioned embodiment, and can be modified as appropriate within the scope of the gist of the present invention.

For example, in the above embodiment, the recording medium holding means 25 is constructed by pasting the raised material 25b on the flexible member 25a, but as shown in FIG. Container body 2
It is also possible to configure the recording medium holding means by pasting it on the inner surface of the recording medium.

Further, as shown in FIG. 5, if a roller 28 is provided at the upper part of the inner surface of the container body 21, the rotation of the roller 28 causes the
P26 can be taken in and out smoothly. roller 2
8 is attached so that a part thereof protrudes from the inner surface of the container body 21.

The recording medium holding means may be provided at least on the inner side surface of the container body on the side where the IP 26 is later inserted into the container body 21, that is, on the end 26b side of the IP 26 in FIG.

This is because even if the recording medium holding means is provided only on the inner side surface of the container body on the side of the end 26b of the IP26, the IP26 can be held.
4, when considering the case where the recording medium storage container is moved by holding the handle part 24, the end 26a side of the IP26 bites into the holding means 25 due to the weight of the IP26, and the end 26b side of the IP26 bites into the holding means 25. This is because the inconvenience of a decrease in the holding force of the recording medium holding means cannot occur. However, by providing recording medium holding means on the inner side surface of the container body on the 126b side of IP26, the surface opposite to this surface, and other surfaces, 1P26 can be held even more reliably. [Effects of the Invention] As explained above. According to the present invention, there is no possibility of scratches due to contact etc. due to the size tolerance of the radiation recording medium, and there is no inconvenience such as the J-ray recording medium falling down when the bed is raised or raised. A recording medium storage container can be provided.
