It is assumed that an impact force or an external force is applied to the radiographing apparatus when taking a picture. Therefore, in order to improve the strength, the housing of the radiography apparatus may be formed of a metal alloy such as aluminum or magnesium, CFRP, or the like. Since metal alloys and CFRPs have conductivity, they shield electromagnetic waves used for wireless data transfer and charging, and transfer efficiency is reduced. Therefore, when data transfer or charging is performed wirelessly, it is necessary to provide a window portion in which a part of the housing is made of a non-conductive material. Further, since metal alloys and CFRP do not have light transmission, it is necessary to provide a window portion in which a part of the housing is made of a light transmitting material even when an indicator by a light source such as an LED is arranged. .. If a large number of such windows are arranged, a plurality of holes are provided in the housing, and many discontinuous strength surfaces are generated, which may reduce the strength of the radiography apparatus.

The present invention has been made in view of the above-mentioned problems, and an object of the present invention is to suppress a decrease in the intensity of the radiography apparatus.

The present invention is a radiography apparatus having a radiation detection panel for detecting radiation and a housing for accommodating the radiation detection panel, wherein the housing has a window portion, and the window portion has the window portion.

According to the present invention, it is possible to suppress a decrease in the intensity of the radiography apparatus.

Embodiments of the present invention will be specifically described with reference to the accompanying drawings. However, the details of the dimensions and the structure shown in each embodiment are not limited to those shown in the text and the drawings. Further, the radiation described below is not limited to X-rays, but also includes α-rays, β-rays, γ-rays, particle beams, cosmic rays and the like.

(First Embodiment)
The radiography apparatus 100 according to the first embodiment will be described with reference to FIGS. 1 to 4.
FIG. 1A is an external view showing an example of a radiation photographing apparatus 100 seen from the incident direction of radiation. FIG. 1B is an external view showing an example of a radiological imaging apparatus 100 seen from the opposite side of FIG. 1A. FIG. 2A is a cross-sectional view of a cross section cut along the line II in FIG. 1A as viewed from the direction of the arrow. FIG. 2B is an external view of the wireless power receiving unit 8 and the LED 9 when viewed from the direction of the arrow Ar1 in FIG. 2A. FIG. 2 (c) is an enlarged view of the periphery of LED 9 in FIG. 2 (a).

The radiography apparatus 100 is irradiated by a radiation generator (not shown) and acquires a radiation image corresponding to the radiation transmitted through the subject. The radiographic imaging device 100 transfers the acquired radiological image data to an external device or displays it on an external display device or the like.
The radiography apparatus 100 includes a radiation detection panel 1, a control board 2, a secondary battery 4, a support base 5, a cushioning material 6, a housing 7, a wireless power receiving unit 8, an LED 9, an antenna 10, and the like.

The radiation detection panel 1 converts the incident radiation into an image signal. In the radiation detection panel 1, the side on which radiation is incident is the detection surface. The radiation detection panel 1 is arranged on a sensor substrate 1a in which a plurality of photoelectric conversion elements are two-dimensionally arranged on a glass substrate, a phosphor layer 1b arranged on the sensor substrate 1a, and a phosphor layer 1b. It also has a fluorescent material protective film 1c. As the plurality of photoelectric conversion elements arranged on the sensor substrate 1a, conversion elements capable of detecting MIS type and PIN type visible light are used. The fluorophore protective film 1c protects the fluorophore layer 1b. As the fluorescent substance protective film 1c, a material having a relatively high moisture resistance is used.

The radiation detection panel 1 has an effective photographing region in which the incident radiation can be imaged as a radiation image. Further, in the radiation detection panel 1, when viewed from the incident direction of radiation, all regions on a plane in which a plurality of photoelectric conversion elements are arranged, or a part of the regions thereof are set as effective photographing regions.
With the above configuration, in the radiation detection panel 1, the phosphor layer 1b emits light due to the incident radiation, and the light emitted is converted into an electric signal by the photoelectric conversion element arranged on the sensor substrate 1a. However, the radiation detection panel 1 may use a direct conversion type conversion element that directly converts radiation into an electric signal instead of the phosphor layer 1b and the photoelectric conversion element.
Further, the radiation detection panel 1 is electrically connected to the control board 2 via the flexible circuit board 3.

The control board 2 reads out the electric signal converted by the radiation detection panel 1 and processes the read electric signal. The control board 2 acquires radiographic image data by converting the electric signal into a digital signal. The control board 2 corresponds to an example of the control unit.
The secondary battery 4 supplies electric power used for operating the radiation detection panel 1 and the control board 2. The secondary battery 4 has a function as a battery. As the secondary battery 4, for example, a lithium ion battery, an electric double layer capacitor, an all-solid-state battery, or the like is used.

The support base 5 supports the components of the radiography apparatus 100 in the housing 7. The support base 5 has a substrate support portion 51 and a leg portion 52. The substrate support portion 51 is formed in a flat plate shape, for example, and supports the radiation detection panel 1 on the incident surface side of the radiation. Further, the substrate support portion 51 supports the control substrate 2, the secondary battery 4, and the like on a surface opposite to the surface that supports the radiation detection panel 1. The legs 52 extend from a surface opposite to the surface supporting the radiation detection panel 1 and are joined to the housing 7.
The cushioning material 6 protects the radiation detection panel 1 from external force. The cushioning material 6 is arranged between the detection surface of the radiation detection panel 1 and the housing 7.

The housing 7 houses the components of the radiography apparatus 100.
The housing 7 is a substantially rectangular parallelepiped, and has a substantially rectangular shape having a long side and a short side when viewed from the incident direction of radiation. The housing 7 has a plurality (for example, four) of connecting the incident portion 71 into which radiation is incident, the bottom portion 72 located on the opposite side of the incident portion 71 with the radiation detection panel 1 interposed therebetween, and the incident portion 71 and the bottom portion 72. With a side portion 73 of. The housing 7 can be configured, for example, by integrating the bottom portion 72 and the side portions 73 and joining separate incident portions 71.

Radiation is incident on the incident portion 71. The incident portion 71 has a substantially flat plate-like surface (outer surface) exposed to the outside. Since the incident portion 71 transmits radiation, it is preferable that the transmittance of the radiation is relatively high. Further, it is preferable that the incident portion 71 has a light weight and can secure a certain strength against an impact. For the incident portion 71, for example, a resin material, CFRP (carbon fiber reinforced plastic), or the like is used.
On the surface of the incident portion 71, an index 711 for indicating the central portion of the effective photographing region and the range of the effective photographing region is written. Index 711 is formed by painting or printing. By visually recognizing the index 711, the user can easily recognize the central portion of the effective photographing area and the effective photographing area. The index 711 may be, for example, a step recessed in the direction of the radiation detection panel 1 as long as the user can recognize the central portion of the effective imaging region and the range of the effective imaging region.

The bottom portion 72 covers the components of the radiography apparatus 100 from the opposite side of the incident portion 71. The bottom portion 72 has a substantially flat plate-like surface (outer surface) exposed to the outside. The bottom portion 72 is substantially parallel to the incident portion 71.
The side portion 73 covers the components of the radiography apparatus 100 from the side. The side portion 73 has a substantially flat plate-like surface (outer surface) exposed to the outside. The side portion 73 is substantially orthogonal to the incident portion 71 and the bottom portion 72.
It is preferable that the bottom portion 72 and the side portion 73 have strength against dropping, impact, etc., weight reduction for the purpose of reducing the burden during transportation, and high operability. For the bottom portion 72 and the side portion 73, for example, a metal alloy such as magnesium or aluminum, CFRP, a fiber reinforced resin, or the like is used. The bottom portion 72 and the side portion 73 may be made of a material having a relatively high magnetic permeability such as SUS430 in order to effectively reduce noise received from the outside of the housing 7.

The wireless power receiving unit 8 charges the secondary battery 4 by receiving electric power transmitted wirelessly. That is, by appropriately charging the secondary battery 4 and maintaining a sufficient amount of electric power at the time of photographing, the user can smoothly perform radiographic imaging. The wireless power receiving unit 8 is controlled to receive electric power by the control board 2.
The LED 9 functions as an indicator indicating the state of the radiographing apparatus 100. For example, the LED 9 emits light to indicate to the user a state in which the radiography apparatus 100 is activated or in an operating state. The LED 9 is an example of a light source.
The antenna 10 wirelessly transmits / receives data to / from an external device. The antenna 10 is controlled by the control board 2 to send and receive data to and from an external device. The antenna 10 is an example of a wireless transmission / reception unit or a wireless data transmission unit.

Here, when the housing 7 is made of a conductive material, the efficiency of receiving electric power by the wireless power receiving unit 8 and the efficiency of data transfer by the antenna 10 are lowered. Further, when the housing 7 is made of a material having no light transmission, the user cannot recognize the light of the LED 9. Therefore, it is conceivable to provide a window portion in the housing 7 to improve the efficiency of transmitting data, electric power, and light. On the other hand, since it is necessary to provide a hole in a part of the housing 7 in the window portion, the structure of the radiography apparatus 100 becomes discontinuous, and stress concentration tends to occur in the vicinity of the window portion. Further, since the rigidity of the housing 7 itself is lowered, the strength of the radiography apparatus 100 is lowered. Since it is assumed that an impact force or an external force is applied to the radiation photographing apparatus 100 when taking a picture or the like, sufficient strength is required so as not to be damaged.

The housing 7 of the present embodiment has a configuration that suppresses a decrease in strength due to a window portion.
As shown in FIGS. 1 and 2, the housing 7 has two window portions 11A and 11B. The windows 11A and 11B are arranged close to one of the four corners of the rectangular housing 7. Specifically, the window portion 11A is arranged on the bottom portion 72, and the window portion 11B is arranged on the side portion 73 on the short side. The window portion 11A and the window portion 11B are arranged at the same position along the side of the short side of the housing 7 or at a position where they overlap each other in the direction along the side of the short side of the housing 7. The window portion 11A has a substantially plate shape continuous with the bottom portion 72 and substantially parallel to the bottom portion 72. Further, the window portion 11B has a substantially plate shape continuous with the side portion 73 and substantially parallel to the side portion 73.

As shown in FIGS. 2A and 2C, a wireless power receiving unit 8, an LED 9, and an antenna 10 are arranged inside the window unit 11A. When viewed from the direction of the arrow Ar1 shown in FIG. 2A, the wireless power receiving unit 8, the LED 9 and the antenna 10 are arranged so as to overlap with each other with respect to the window unit 11A. That is, when viewed from a direction orthogonal to the outer surface of the window portion 11A, the wireless power receiving portion 8, the LED 9, and the antenna 10 are arranged so as to overlap with each other with respect to the window portion 11A. Specifically, the wireless power receiving unit 8 and the LED 9 are arranged along the inner surface of the window portion 11A, and the antenna 10 is arranged at a position away from the inner surface of the window portion 11A. Therefore, the window portion 11A has the functions of a window portion for receiving electric power by the wireless power receiving portion 8, a window portion for transmitting the light of the LED 9, and a window portion for transferring data by the antenna 10. There is. In particular, since the wireless power receiving unit 8 and the LED 9 are arranged in contact with the inner side surface of the window unit 11A, the window unit 11A mainly functions as a window unit for the wireless power receiving unit 8 and the LED 9.
On the other hand, the antenna 10 is arranged inside the window portion 11B. When viewed from the direction of the arrow Ar2 shown in FIG. 2A, the antenna 10 is arranged so as to overlap with the window portion 11B. That is, when viewed from a direction orthogonal to the outer surface of the window portion 11B, the antenna 10 is arranged so as to overlap with the window portion 11B. Specifically, the antenna 10 is arranged at a position away from the inner side surface of the window portion 11B. Therefore, the window portion 11B has a function of a window portion for transferring data by the antenna 10.

Here, the wireless power receiving unit 8 and the LED 9 are configured to overlap each other. Specifically, the LED 9 is arranged so as to be located between the wireless power receiving unit 8 and the inner surface of the window unit 11A.
FIG. 2B is a diagram showing the configurations of the wireless power receiving unit 8 and the LED 9 as viewed from the direction of the arrow Ar1 in FIG. 2A. As shown in FIG. 2B, the LED 9 is located substantially in the center of the wireless power receiving unit 8. Further, the wireless power receiving unit 8 is larger than the substrate 91 on which the LED 9 is mounted, and is arranged inside the window portion 11A so as to cover the substrate 91 from the inside of the housing 7. By configuring the wireless power receiving unit 8 and the LED 9 in this way, the window unit of the wireless power receiving unit 8 and the LED 9 can be shared by one window unit 11A, and the size of the window unit 11A can be reduced. can. Therefore, it is possible to prevent the strength of the housing 7 from decreasing. Further, by arranging the wireless power receiving unit 8 and the LED 9 as described above, it is possible to save space as compared with the case where they are arranged separately, and it is possible to reduce the size of the radiological imaging device 100.

Further, the antenna 10 is supported on the surface of the substrate support portion 51 opposite to the surface that supports the radiation detection panel 1. As shown in FIG. 2A, the antenna 10 is arranged at a position where it does not overlap with the wireless power receiving unit 8 and the LED 9 when viewed from the direction of the arrow Ar1. Further, the antenna 10 is located inside each of the window portion 11A and the window portion 11B. Therefore, since the data is transferred through the two windows 11A and 11B, the radiation range of the antenna 10 can be expanded.
If the radiation characteristics of the antenna 10 can be sufficiently obtained only by the window portion 11A, the housing 7 does not have to have the window portion 11B. In this case, the window portion of the wireless power receiving unit 8, the LED 9 and the antenna 10 can be shared by one window unit 11A. Therefore, it is possible to further suppress the decrease in the strength of the housing 7.

Here, the window portion 11A is made of at least a part of a light-transmitting material so that the light of the LED 9 can be visually recognized by the user. For example, the window portion 11A uses a resin, a fiber reinforced resin, or the like, and all or part of the window portion 11A is used as a light transmitting portion.
When a part of the window portion 11A is used as a light transmitting portion, it can be configured by integrally molding a light-transmitting material and a non-light-transmitting material by molding a different material. Alternatively, the light-transmitting material and the non-light-transmitting material may be separately molded and bonded to each other by an adhesive, industrial tape, ultrasonic welding, or the like.

When all of the window portion 11A is made of a light-transmitting material, it is desired to transmit by arranging a sheet or the like having a coating, printing, or light-shielding property on the outer surface or the inner side surface of the window portion 11A. It is possible to prevent transmission at a position where it is not present, and to adjust the amount of transmitted light.
On the other hand, the window portion 11B does not function as the window portion of the LED 9. Therefore, the window portion 11B does not need to be made of a light-transmitting material, and at least a part thereof may be a non-conductive material.
Further, the windows 11A and 11B are set to a thickness suitable so that the efficiency of power transfer and data transfer is not significantly reduced. Further, the window portion 11A is set to a thickness suitable for transmitting the light of the LED 9.

Further, in order to provide the window portions 11A and 11B in the housing 7, the window portions 11A and 11B are bonded to the housing 7 with an adhesive, industrial tape or the like, or fastened with screws or the like. At this time, the waterproof property can be improved by interposing a waterproof packing between the windows 11A and 11B and the housing 7, or by attaching the waterproof packing with a waterproof double-sided tape or the like. Further, the housing 7 may be configured by integrally molding the housing 7 by outsert molding in which the windows 11A and 11B are incorporated or molding of different materials. By integrally molding, the interface strength between the housing 7 and the window portions 11A and 11B can be improved, and the strength of the radiography apparatus 100 can be improved.

By arranging the wireless power receiving unit 8 and the LED 9 so as to be in contact with the inner side surface of one window unit 11A in this way, the window unit of the wireless power receiving unit 8 and the window unit of the LED 9 can be made common. The number of windows provided in the housing 7 can be reduced. Further, by arranging the wireless power receiving unit 8, the LED 9 and the antenna 10 inside one window unit 11A, the window unit of the wireless power receiving unit 8, the window unit of the LED 9 and the window unit of the antenna 10 are shared. The number of windows provided in the housing 7 can be reduced. Therefore, it is possible to prevent the strength of the housing 7 from decreasing. Further, when the wireless power receiving unit 8 is arranged so as to overlap the window unit 11A when viewed from a direction orthogonal to the outer surface of the window unit 11A, the wireless power receiving unit 8 receives power. Efficiency can be improved. Similarly, by arranging the LED 9 so as to overlap the window portion 11A, the visibility of the LED 9 can be improved. Similarly, by arranging the antenna 10 so as to overlap with the window portion 11A, the efficiency of data transfer by the antenna 10 can be improved.

In the present embodiment, the case where the wireless power receiving unit 8, the LED 9 and the antenna 10 are arranged in one window portion 11A has been described, but the present invention is not limited to this case, and any one of the LED 9 and the antenna 10 and the wireless power receiving unit 8 are used. May be arranged.

Next, the radiography apparatus 110 as a modification of the first embodiment will be described with reference to FIGS. 3 and 4. The radiography apparatus 100 shown in FIGS. 1 and 2 had a window portion 11A on the bottom 72 and a window portion 11B on the side portion 73, but the radiography apparatus 110 shown in FIGS. 3 and 4 is inclined. The portion 74 has a window portion 11C. The same configurations as those in FIGS. 1 and 2 are designated by the same reference numerals.

FIG. 3A is an external view showing an example of the radiographing apparatus 110 seen from the incident direction of radiation. FIG. 3B is an external view showing an example of the radiological imaging apparatus 110 seen from the opposite side of FIG. 3A. FIG. 4A is a cross-sectional view of a cross section cut along the line II-II in FIG. 3A as viewed from the direction of the arrow. FIG. 4 (b) is an enlarged view of the periphery of the LED 9 in FIG. 4 (a).
The housing 7 of the radiography apparatus 110 of the present embodiment has an inclined portion 74 between the bottom portion 72 and the side portion 73. The inclined portion 74 functions as a connecting portion that continuously connects the bottom portion 72 and the side portion 73. Here, "continuously connecting" means that the bottom portion 72 or the side portion 73 does not intervene again between the bottom portion 72 and the side portion 73.
The inclined portion 74 is inclined with respect to the bottom portion 72 and the side portion 73. Further, the inclined portion 74 is continuously formed over substantially the entire circumference of the housing 7. Further, as shown in FIG. 4A, the inclined portion 74 has a substantially flat plate-like surface (outer surface) exposed to the outside.

The housing 7 of the present embodiment has one window portion 11C. The window portion 11C is arranged on the short side of the rectangular housing 7 at substantially the center of the length along the side of the short side. Further, as shown in FIG. 4A, the window portion 11C is formed over the bottom portion 72 and the side portion 73 of the housing 7. Specifically, the window portion 11C has a substantially plate-shaped first portion 111C that is continuous with the inclined portion 74 and substantially parallel to the inclined portion 74. Further, the window portion 11C has a substantially plate-shaped second portion 112C which is continuous with the bottom portion 72 and substantially parallel to the bottom portion 72, and a substantially plate-shaped third portion 112C which is continuous with the side portion 73 and substantially parallel to the side portion 73. Has a site 113C and.

As shown in FIGS. 4A and 4B, a wireless power receiving unit 8, an LED 9 and an antenna 10 are arranged inside the window unit 11C. The wireless power receiving unit 8, the LED 9, and the antenna 10 are arranged so as to overlap with each other with respect to the window unit 11C when viewed from either the arrow Ar1 direction or the arrow Ar2 direction shown in FIG. 4A. Further, when viewed from a direction orthogonal to the outer surface of the first portion 111C, the wireless power receiving unit 8 and the LED 9 are arranged so as to overlap with each other with respect to the first portion 111C. Further, when viewed from a direction orthogonal to the outer surface of the second portion 112C, the antenna 10 is arranged so as to overlap with the second portion 112C. Specifically, the wireless power receiving unit 8 and the LED 9 are arranged along the inner surface of the first portion 111C, and the antenna 10 is arranged along the inner surface of the second portion 112C. Therefore, the window portion 11C has the functions of the window portion for the wireless power receiving portion 8, the window portion for the LED 9, and the window portion for the antenna 10. As in FIG. 2 described above, the wireless power receiving unit 8 and the LED 9 are configured to be overlapped with each other.

By arranging the wireless power receiving unit 8, the LED 9 and the antenna 10 in one window unit 11C in this way, the window unit of the wireless power receiving unit 8, the window unit of the LED9, and the window unit of the antenna 10 can be made common. Therefore, the number of windows provided in the housing 7 can be reduced. Therefore, it is possible to prevent the strength of the housing 7 from decreasing. Further, since the window portion 11C is located over the bottom portion 72 and the side portion 73, the wireless power receiving unit 8 can receive power more widely than when the window portion 11C is formed only on the bottom portion 72 and the side portion 73. At the same time, the visibility of the LED 9 and the radiation characteristics of the antenna 10 can be improved.

In the present embodiment, the case where the wireless power receiving unit 8 and the LED 9 are configured to overlap each other has been described, but the present invention is not limited to this case. For example, the wireless power receiving unit 8 and the antenna 10 may be overlapped with each other, the LED 9 and the antenna 10 may be overlapped with each other, or the wireless power receiving unit 8, the LED 9 and the antenna 10 may be overlapped with each other. With such a configuration, space can be saved and the sizes of the windows 11A, 11B, and 11C can be further reduced.
In the above-mentioned modification, the case where the window portion 11C has the first portion 111C has been described, but the case is not limited to this case, and the second portion 112C and the second portion 112C do not have the first portion 111C. The portion 113C of 3 may be continuously formed.

Here, when the wireless power receiving unit 8 and the antenna 10 are in close proximity to each other, there is a risk that the operations may interfere with each other and cause a malfunction. Therefore, the following method of suppressing interference may be applied.
First, in the radiographing devices 100 and 110, the frequency band used when the wireless power receiving unit 8 wirelessly receives power and the frequency band used when the antenna 10 wirelessly transfers data are different. Set to. In this way, by setting the wireless power receiving unit 8 and the antenna 10 so that their frequency bands are different from each other, it is possible to suppress interference with each other's operations.

Secondly, the control board 2 of the radiographing devices 100 and 110 controls the wireless power receiving unit 8 and the antenna 10 so as not to operate at the same time, and the period when power is received wirelessly and the antenna 10 transfers data. Do not overlap with the period when you do. Specifically, the control board 2 controls the wireless power receiving unit 8 so as not to receive electric power wirelessly during the period when the data is transferred to the outside by the antenna 10. On the other hand, the control board 2 controls the wireless power receiving unit 8 to receive electric power wirelessly only during the period when the data is not transferred by the antenna 10. In this way, by controlling the wireless power receiving unit 8 and the antenna 10 so as not to operate at the same time, it is possible to suppress interference with each other's operations. Therefore, stable data transfer is possible and the efficiency of wireless power reception can be improved.

(Second embodiment)
The radiography apparatus 120 according to the second embodiment will be described with reference to FIG.
FIG. 5A is a cross-sectional view showing an example of the radiography apparatus 120. FIG. 5B is an enlarged view of the periphery of the LED 9 in FIG. 5A. The same configurations as those in the first embodiment are designated by the same reference numerals.

The radiography apparatus 120 has a light-shielding sheet 12 located between the LED 9 and the radiation detection panel 1. The light-shielding sheet 12 corresponds to an example of a light-shielding layer. The light-shielding sheet 12 is larger than the wireless power receiving unit 8 and is arranged inside the window portion 11A so as to cover the wireless power receiving unit 8 from the inside of the housing 7. Here, since the LED 9 is located between the wireless power receiving unit 8 and the inner surface of the window portion 11A, the light-shielding sheet 12 covers the LED 9 from the inside of the housing 7 via the wireless power receiving unit 8.

The light-shielding sheet 12 shields the light from the LED 9 so that it does not reach the radiation detection panel 1. As described above, in the radiation detection panel 1, the phosphor layer 1b emits light due to the incident radiation, and the photoelectric conversion element on the sensor substrate 1a converts the emitted light into an electric signal. Therefore, if the light of the LED 9 enters from the periphery of the radiation detection panel 1, it has an unintended effect on the radiation image.
By arranging the light-shielding sheet 12 between the LED 9 and the radiation detection panel 1, it is possible to prevent the light of the LED 9 from reaching the radiation detection panel 1. Further, since the light-shielding sheet 12 is arranged inside the window portion 11A, it is possible to prevent light from being transmitted from the outside in the region of the window portion 11A where the light-shielding sheet 12 is arranged, and to prevent light leakage.

The light-shielding sheet 12 may be a magnetic sheet having magnetism. By using a magnetic sheet, a part of the magnetic field generated when receiving electric power wirelessly can be changed to the direction of the magnetic field along the magnetic sheet, and the intrusion of the magnetic field into the radiography apparatus 100 can be suppressed. be able to. Further, when there is a metal material or the like in the radiography apparatus 100, it is possible to suppress the influence of the repulsive magnetic field generated by the metal material, which repels the magnetic field when receiving electric power wirelessly. Therefore, it is possible to improve the efficiency of receiving power wirelessly. Further, the influence of the magnetic field on the radiation detection panel 1 and the control board 2 can be suppressed, and noise and the like of the radiation image can be reduced.

(Third embodiment)
The radiography apparatus 130 according to the third embodiment will be described with reference to FIGS. 6 and 7.
FIG. 6A is an external view showing an example of the radiographing apparatus 130 seen from the incident direction of radiation. FIG. 6B is an external view showing an example of the radiography apparatus 130 seen from the opposite side of FIG. 6A. FIG. 7 (a) is a cross-sectional view taken along the line III-III in FIG. 6 (a) as viewed from the direction of the arrow. FIG. 7 (b) is an enlarged view of the periphery of the LED 9 in FIG. 7 (a).
