It is characterized in that it is provided so as to be able to be wound around a shaft provided at the edge portion of the opening. In the radiation shielding container according to claim 2, a door having a shutter structure including a radiation shielding material is provided so as to be openable and closable along the opening, and the shutter structure door is provided so as to be slidable along a rail. It is characterized by Furthermore, the radiation shielding container according to claim 3 is characterized in that a bellows-shaped door containing a radiation shielding material is provided so as to be openable and closable along the opening.

[0006]

[Operation] According to the present invention, a sheet-like door (3) containing a radiation shielding material is provided at an opening so as to be openable and closable, and the sheet-like door (3) provided at an edge portion of the opening ( By providing it so that it can be rolled up in 7), the entire surface of the opening can be opened. Further, a door (23) having a shutter structure containing a radiation shielding material is slidably movable along a rail (28) provided at the opening end, or a bellows-like door (29) containing a radiation shielding material is provided at the opening. Since it is provided so that it can be opened and closed, it is possible to similarly open the entire surface of the opening.

[0007]

FIG. 1 shows an embodiment of the radiation shielding container according to the present invention. The radiation shielding container 1 is placed on a cabinet 10 and is composed of a frame body 2 fixed to the cabinet 10 and a sheet-like open / close door 3 provided on the frame body 2. Sheet open / close door 3
Is formed of a radiation shielding material such as lead. The frame body 2 is formed of a member such as an iron plate into a rectangular parallelepiped shape,
On the front surface and both side surfaces, openings 11 and 12 for operating a radiation generator, a radiation utilizing apparatus, etc. (not shown) housed inside are provided. This opening 11 and 1
2 is formed widely over the entire front surface and side surface of the frame body 2. The upper surface and the back surface of the frame 2 are covered with an iron plate or a metal-containing synthetic resin plate.

The sheet-like opening / closing door 3 is provided in each of the openings 11 and 12 of the frame body 2 and is formed of a radiation shielding sheet made of synthetic resin or rubber containing a metal such as lead. As shown in FIG. 2, the sheet-shaped opening / closing door 3 is housed in a state of being rolled up in a housing case 5 provided in the frame body 2. Also, this sheet-shaped opening / closing door 3
Is formed in such a size that the openings 11 and 12 of the frame body 2 can be closed without a gap.

A storage case 5 for storing the sheet-like opening / closing door 3.
2 is formed in a cylindrical shape having a slit 6 for pulling out the sheet-like opening / closing door 3 as shown in FIG. 2, and is provided vertically inside the corner portion of the frame body 2. A winding shaft 7 for winding the sheet-shaped opening / closing door 3 is rotatably supported in the center of the inside of the storage case 5, and one end of the sheet-shaped opening / closing door 3 is fixed to the winding shaft 7. Further, the winding shaft 7 has a coil spring 8 as shown in FIG.
Is urged to rotate counterclockwise in FIG. When the winding shaft 7 is rotated by the bias of the coil spring 8, the sheet-shaped opening / closing door 3 is wound around the winding shaft 7 and stored in the storage case 5. Further, a hooking hook 13 and an operating knob 14 are provided at the other end of the sheet-like opening / closing door 3. A locking portion 15 for locking the hook 13 is provided at an edge portion of the opening 11 and 12 of the frame body 2 opposite to the storage case 5.

According to the present embodiment, with the above-mentioned configuration, the sheet-shaped opening / closing door 3 is opened when the opening / closing door 3 is opened.
Is caught and stored in the storage case 5, and the opening 11,
Almost the entire surface of 12 is open. When closing the openings 11 and 12, the sheet-like open / close door 3 is pulled out from the storage case 5 against the winding force of the winding shaft 7 by holding the operation knob 14, and the hooking hook 13 is engaged with the locking portion 15 of the openings 11 and 12. Engage. As a result, the closed state of the sheet opening / closing door 3 is maintained. When the sheet-shaped opening / closing door 3 is opened, if the hook 13 is removed from the locking portion 15, the sheet-shaped opening / closing door 3 is automatically stored in the storage case 5 by the winding of the winding shaft 7.

In the above embodiment, the sheet-like opening / closing door 3 is opened and closed laterally left and right. However, by providing the storage case 5 at the upper or lower corners of the openings 11 and 12, It is also possible to open and close the sheet-shaped opening / closing door 3 up and down. Further, although the hooks 13 are used to maintain the closed state of the sheet-like open / close door 3, a structure such as a magnet may be used instead.

4 and 5 show another embodiment of the radiation shielding container according to the present invention. This radiation shielding container 20
Has a container body 21 formed of a member such as an iron plate placed on the cabinet 10 and a shutter door 23. The container main body 21 has both side surface portions 25 and 26 each having a round upper portion and a back surface portion 27 that covers the back surface side from almost half of the upper surface, and an opening 2 is provided from substantially half of the upper surface to the front surface side.
2 is formed. The shutter door 23 is formed in a shutter structure in which an iron plate or a lead plate having a sufficient thickness to shield radiation is attached to the back side, and both side portions 2
It is installed so as to be slidable along rails 28 provided on the periphery of 5, 26. With such a configuration, the opening 22 can be opened and closed by sliding the shutter door 23 in the vertical direction, and the entire opening 22 can be opened. Further, when the opening 28 is opened, the shutter door 23 is housed inside the back surface portion 27.

The shutter door 23 is provided with the storage case as described in the first embodiment above the rear portion 27,
The shutter door 23 may be rolled up and stored in the storage case. However, the structure is simpler if the above-mentioned structure of only sliding movement is used. Further, in the second embodiment, the door may be the sheet-like opening / closing door 3 of the first embodiment and may be housed in a storage case.

FIG. 6 shows still another embodiment of the radiation shielding container according to the present invention. In this embodiment, an opening / closing door 29 having a bellows shape is combined with the opening 11 of the frame body 2 of the first embodiment (FIG. 1). In the case of the bellows-shaped opening / closing door 29, since the opening / closing door itself is opened / closed, it is not necessary to provide the storage case 5 such as the radiation shielding sheet 4. Further, it is also conceivable that the container body 21 in the second embodiment (FIG. 4) is provided with a bellows-like opening / closing door 29 to open / close.
In either case, it is possible to open the entire opening.
