(A surface orthogonal to the irradiation surface) will be described as a side surface.
(First embodiment)
FIG. 1 is a diagram illustrating an external appearance of a radiation imaging apparatus 101 viewed in plan from the radiation irradiation side. 2A and 2B are diagrams showing the internal configuration of the radiation imaging apparatus 101 in plan view of the side surface and the back surface. FIG. 3 is a diagram illustrating a state in which the connection cable 109 of the radiation imaging apparatus 101 in FIG.

The radiation imaging apparatus 101 has a rectangular shape including sides 110a to 110d when viewed in plan from the side irradiated with radiation, has corners 111a to 111d, and is formed with a predetermined thickness.
The radiation imaging apparatus 101 includes a housing 102, an input / output unit 103, a radiation detection panel 104, a circuit unit 105, a support base 106, a connection cable 109, and the like.

The housing 102 accommodates the components of the radiation imaging apparatus 101, that is, the radiation detection panel 104, the circuit unit 105, the support base 106, the connection cable 109, and the like.

The input / output unit 103 is disposed at the peripheral edge of the housing 102. The input / output unit 103 performs at least one of information input and information output. Specifically, the input / output unit 103 includes a connector 103a, a display unit 103b, an antenna 103c, and interface units (switches, buttons, etc.) not shown. The connector 103a is a connection part through which power and electric signals are supplied to the radiation imaging apparatus 101. The display unit 103b displays information regarding the radiation imaging apparatus 101. The information regarding the radiation imaging apparatus 101 is information for visually recognizing the state of the radiation imaging apparatus 101. The information related to the radiation imaging apparatus 101 includes, for example, information related to the driving state of the radiation detection panel, the reception state of radio waves by the antenna 103c, the set imaging mode, and the remaining battery level. The antenna 103c transmits and receives information to and from the outside wirelessly. The input / output unit 103 may be disposed on the same surface, side surface, or back surface of the peripheral portion of the housing 102 as the irradiation surface, and is disposed across these two surfaces or three surfaces. Also good. Note that the input / output unit 103 is arranged in a region different from a region in which at least the effective pixel region of the radiation detection region is orthographicly projected on the irradiation surface.
In the present embodiment, the connector 103a and the display unit 103b are arranged at diagonal positions.

  The radiation detection panel 104 is accommodated in the housing 102 and is formed of a rectangular flat plate. The radiation detection panel 104 is a so-called indirect conversion type radiation detection panel in which irradiated radiation is converted into visible light by the phosphor layer, and the converted visible light is detected and converted into signal information. The radiation detection panel 104 is laminated | stacked in order of the board | substrate, the conversion element, the fluorescent substance layer, and the reflective sheet from the irradiation surface side. A glass plate is often used for the substrate because it has no chemical action with a semiconductor element, can withstand the temperature of a semiconductor process, and needs for dimensional stability. The conversion elements are two-dimensionally arranged on the substrate surface by a semiconductor process. The phosphor layer is bonded onto the arranged light source conversion elements. The reflection sheet is formed of a metal such as aluminum that easily reflects light, and covers the phosphor layer. The radiation detection panel 104 may be a so-called direct conversion type radiation detection panel that directly detects irradiated radiation and converts it into signal information.

The circuit unit 105 is electrically connected to the radiation detection panel 104 and performs electrical signal communication with the radiation detection panel 104. The circuit unit 105 is disposed on the side of the radiation detection panel 104 opposite to the surface irradiated with radiation. The circuit unit 105 includes at least one of a drive circuit board 105a and a read circuit board 105b. The drive circuit board 105 a supplies a drive signal to the radiation detection panel 104. The read circuit board 105 b reads an electrical signal from the radiation detection panel 104. Here, circuit portions 105 are arranged on the four sides of the radiation imaging apparatus 101 in order to improve the reading efficiency of electric signals.
The support base 106 is formed in a rectangular flat plate shape. The support base 106 supports the circuit unit 105 on the opposite side where the radiation detection panel 104 is disposed. Specifically, as shown in FIG. 2B, the support base 106 supports the drive circuit board 105a and the readout circuit board 105b at positions along the periphery. The support base 106 supports the electric substrate 107 on the inner side of the drive circuit board 105a and the readout circuit board 105b. The electric board 107 is connected to the input / output unit 103 via a flexible cable (FFC) 108.

The connection cable 109 is connected so that an electrical signal can be communicated between the radiation detection panel 104 and the circuit unit 105. As the connection cable 109, a flexible printed wiring board (FPC) having flexibility is used. Here, the plurality of connection cables 109 are wired around the radiation detection panel 104 and connected to the radiation detection panel 104 and the circuit unit 105 in a state of being wired in the thickness direction so as to straddle the outer peripheral edge of the support base 106. To do. Here, there are eight connection cables 109 arranged on the sides 110a and 110c of the radiation imaging apparatus 101, and there are six connection cables 109 arranged on the sides 110b and 110d, respectively. The plurality of connection cables 109 on the same side are the same length and are arranged in parallel. In particular, adjacent connection cables 109 are arranged side by side without a gap (substantially a gap). Here, “substantially no gap” does not only refer to a case where there is no gap at all in physical contact, and may include a case where there is almost no space. That is, a sufficient space is not provided between the adjacent connection cables 109, which indicates a state in which no other component is disposed (a state in which a space to be disposed is not provided).
In addition, as shown in FIG. 3, a plurality of gate wirings 112 a for controlling drive signals and data wirings 112 b for reading out charges are arranged in the pixel region of the radiation detection panel 104. The gate wiring 112a and the data wiring 112b and the connection cable 109 are connected via the connector wiring 112c.

In the present embodiment, the plurality of connection cables 109 can be arranged close to one side at each side 110a to side 110d of the radiation imaging apparatus 101 by inclining the connector wiring 112c.
Specifically, the plurality of connection cables 109 on the side 110a and the side 110b are arranged so as to be biased toward the corner portion 111a. The plurality of connection cables 109 connected to the side 110c and the side 110d are arranged so as to be biased toward the corner 111c.

  In this way, by bringing the plurality of connection cables 109 to one side on each side of the radiation imaging apparatus 101, a space (area) in which the connection cable 109 is not arranged is provided on the other side of each side. The part 103 can be arranged. Specifically, as shown in FIG. 2B, the input / output unit 103 can be arranged along the same side of the radiation imaging apparatus 101 to which the connection cable 109 is connected. Accordingly, since the input / output unit 103 does not need to be disposed further outside the connection cable 109, the size of the radiation imaging apparatus 101 in the planar direction can be reduced.

Further, the input / output unit 103 can be arranged at the same height of the connection cable 109. Specifically, as shown in FIG. 2A, the display unit 103b is disposed so as to spatially overlap with the connection cable 109 wired in the thickness direction. Here, spatially overlapping means that at least a part may be physically touching and overlapping, or may be overlapping via space without being physically touching. That is, when the thickness of the display portion 103b is extended in parallel along the side 110b, the display portion 103b and the connection cable 109 overlap each other by the thickness T1 in the thickness direction.
2B, when the thickness of the antenna 103c is extended in parallel along the side 110a, the antenna 103c and the connection cable 109 arranged on the side 110a overlap each other. ing.
2B, when the thickness of the display unit 103b is extended in parallel along the side 110c, the connection cable 109 disposed on the display unit 103b and the side 110c Are overlapping.
2B, when the thickness of the connector 103a is extended in parallel along the side 110d, the connector 103a and the connection cable 109 arranged on the side 110d overlap each other. ing.

As described above, according to the present embodiment, the connection cable 109 in which the input / output unit 103 is wired in the thickness direction as viewed from the direction orthogonal to the direction in which the radiation is applied, that is, from the side of the housing 102, and They were arranged so as to overlap spatially. Therefore, since the input / output unit 103 does not need to be arranged on the back side of the connection cable 109 or the back side of the circuit unit 105, the thickness of the radiation imaging apparatus 101 can be reduced. In particular, when the thickness of the input / output unit 103 is extended in parallel along each side when viewed from the side of the housing 102, the radiation imaging apparatus has an amount corresponding to the overlapping thickness of the input / output unit 103 and the connection cable 109. The thickness of 101 can be reduced.
In addition, when extending the thickness of the input / output unit 103, it is preferable to extend the maximum thickness of the input / output unit 103. Further, when the thickness of the input / output unit 103 is extended, it may be extended in parallel along each side of the radiation detection panel 104.

Therefore, the radiation imaging apparatus 101 can reduce the size of the radiation imaging apparatus 101 even when the input / output unit 103 is arranged in the casing 102. For example, the casing 102 has a cassette, a narrow frame, or a thin frame. Any size can be applied.
In the present embodiment, the case where the connection cable 109 is moved to one side in all of the sides 110a to 110d of the radiation imaging apparatus 101 has been described, but the side where the input / output unit 103 is not arranged is arranged to be moved to one side. It does not have to be. In the present embodiment, the case where a plurality of connection cables 109 are arranged on the same side has been described. However, a single connection cable can be formed by integrally forming the plurality of connection cables 109 arranged on the same side. You may arrange.

Next, the case where the radiation imaging apparatus 101 is housed in the cradle 113 and charged will be described with reference to FIG. FIG. 4 is a diagram illustrating a state in which the radiation imaging apparatus 101 is charged by the cradle 113.
The cradle 113 is held so as to cover a part of the radiation imaging apparatus 101. At the bottom of the cradle 113, a power supply terminal 114 connected to the connector 103a is disposed. In the radiation imaging apparatus 101 of the present embodiment, the display unit 103b is disposed at a diagonal position on the connector 103a, so that the display unit 103b is prevented from being hidden by the cradle 113. Therefore, even if the radiation imaging apparatus 101 is accommodated in the cradle 113, the display unit 103b can be confirmed without impairing visibility.
Note that the arrangement of the connector 103a and the display unit 103b is an example, and any arrangement that does not impair visibility when the radiation imaging apparatus 101 is accommodated in the cradle 113 may be used. Therefore, the connector 103a and the display unit 103b in the radiation imaging apparatus 101 need only be disposed on the peripheral sides of the housing 102 and on the opposing side surfaces. When visibility is not taken into consideration, the connector 103a and the display unit 103b may be disposed on the same side surface of the housing.

In the radiation detection panel 604, an aluminum sheet 604a, a phosphor layer 604b, a PI layer 604c, and a reflection sheet 604d are laminated from the irradiation surface side. The support base 606 has a support plate 606a and leg portions 606b.

  The light source unit 612 irradiates the radiation detection panel 604 with refreshing light to remove charges accumulated in the radiation detection panel 604. The light source unit 612 is disposed between the radiation detection panel 604 and the support base 606 and is supported by the support base 606. In the light source unit 612, a diffusion sheet 612a, a diffusion sheet 612b, a light guide plate 612c, and a reflection sheet 612d are stacked from the radiation detection panel 604 side, and the light source 512a is disposed in the vicinity of the housing 602. In the present embodiment, the light source 512a of the display unit 603b and the light source 512a of the light source unit 612 are common.

  Therefore, the electric board 507 can display the information of the radiation imaging apparatus 601 by emitting the light source 512a and irradiate the radiation detection panel 604 with refreshing light. Note that the electric substrate 507 can emit light by changing the color of the light source 512a in accordance with the purpose. Specifically, the electric board 507 emits white light, for example, using the light source 512a as refresh light. At this time, since the polarizing member 602g of the housing 602 is configured to block the wavelength of light corresponding to the refresh light, the refresh light can be prevented from leaking from the housing 602 to the outside. On the other hand, when displaying information of the radiation imaging apparatus 601, the electric board 507 can visually recognize the display unit 603 b by emitting light other than the wavelength of light corresponding to the refresh light.

As described above, the present invention has been described together with various embodiments, but the present invention is not limited to these embodiments, and can be modified within the scope of the present invention. May be.
In the embodiment described above, the case where the circuit unit 105 is supported by the support base 106 or the support base 606 has been described. However, the circuit unit 105 is not limited to this case and is supported by other members such as the housing 102 and the housing 602. May be.
