(First embodiment)
FIG. 1 is a cross-sectional plan view illustrating a radiation imaging apparatus (electronic cassette) according to the present embodiment from a surface facing a radiation incident surface. FIG. 2 is a perspective view showing a charging cradle (storage device) in the present embodiment. FIG. 3 is a plan view of a configuration in which the electronic cassette according to this embodiment is stored in a charging cradle as viewed from above. FIG. 4 is a plan view of a configuration in which the electronic cassette according to the present embodiment is stored in a charging cradle as viewed from the side.

  The electronic cassette 1 has an outer size equivalent to a cassette standardized by JIS Z 4905. A radiation detection panel 14 and a holding base 21 are arranged in this order from the radiation incident surface side in the housing 13 made of a material having a high radiation transmittance on the radiation incident surface side.

  The radiation detection panel 14 has, on an insulating substrate (for example, a glass substrate), a pixel having a conversion element for converting a radiation dose into a charge amount and a switch element for transferring an electric signal based on the charge amount. The device is a photographing panel in which a plurality of devices are arranged two-dimensionally. The radiation detection panel 14 is provided with a scintillator (not shown) as a configuration for converting a radiation dose into a charge amount. The radiation detection panel 14 is connected to a readout circuit 15 for reading out electrical signals from the pixel devices of the radiation detection panel 14 via the flexible circuit board 19. Further, it is connected via a flexible circuit board 20 to a drive circuit 16 for supplying a drive signal having a voltage for conducting the switch element to the switch element.

  The first surface on the radiation incident surface side of the holding base 21 or the second surface opposite to the first surface is, for example, any heavy metal of Pb, Ba, Ta, Mo, W The radiation detection panel 14 is held via a radiation shielding member (not shown) having a material that shields radiation, such as a material containing a material such as stainless steel. Further, on the second surface opposite to the first surface of the holding base 21, a read circuit 15, a drive circuit 16, various control circuits 17, 18 for controlling electric signal control, DC voltage conversion, and the like, drive A secondary battery 11 for supplying electric power for use, a wireless transmission unit that wirelessly transmits an image signal to an external device, a wireless module unit 23 that functions as a wireless reception unit, and the like are disposed. Further, on the surface (for example, a side surface) other than the radiation incident surface of the housing 13, the external connection terminal unit 12 and the antenna unit 24 for performing power supply and data communication from an external device, a power ON / OFF switch, and a status display A user IF unit 22 and the like mounted with a unit are arranged.

  As shown in FIG. 2, the cradle 2 is a storage device that stores the electronic cassette 1, and includes a bottom surface portion B, a first wall surface A adjacent to the bottom surface portion B, and a first wall surface A adjacent to the bottom surface portion B. And a storage portion having a second wall surface B provided at a position opposite to each other. Further, the storage section may further include a third wall surface D adjacent to the bottom surface portion B, the first wall surface A, and the second wall surface C.

  By storing the electronic cassette 1 in the slot portion (storage portion) of the cradle 2 shown in FIG. 2, the power supply connector 31 provided on the cradle 2 and the external connection terminal portion 12 of the electronic cassette 1 are connected, and the electronic cassette 1 The secondary battery 11 can be charged. In this case, the power supply connector 31 functions as a power supply unit that supplies power to charge the electronic cassette 1. In addition, the cradle 2 is provided with an LED display unit 30 and can display the charge state of the secondary battery 11. The arrangement position of the LED display unit 30 is not limited to the example of FIG. 2, and can be provided at an arbitrary position of the cradle 2. Further, when the electronic cassette 1 is configured to be able to supply power in a non-contact manner, the cradle 2 has a power supply unit corresponding to this. In this case, the cradle 2 can constitute a power supply coil or a power supply antenna instead of the power supply connector 31 as a power supply unit having a power supply function.

  Further, as shown in FIG. 3, the length L1 (the horizontal length of the first wall surface A) and L2 (the horizontal length of the second wall surface C) of the cradle 2 holding the electronic cassette 1 are as follows. The bottom portion B is configured to be shorter than the length L3. When the length L1 is different from the length L2 and the user operates from a position perpendicular to the insertion / removal direction, the user pulls up to L2 with one hand when pulling out, and the electronic cassette 1 in the direction of the angle θ with the bottom B being supported. Since the orientation can be changed and held with both hands, the operation from the pulling out to the holding can be performed smoothly. Even during insertion, the contact between the bottom surface B and the wall L1 facilitates the operation of inserting between the walls L1 and L2. Moreover, the edge part of the side by which the electronic cassette 1 is inserted / extracted in the 2nd wall surface C has the inclination part E. As shown in FIG. By having the inclined portion E, the operation of changing the direction of the electronic cassette 1 in the direction of the angle θ can be made smoother while being in contact with the second wall surface C.

  Using FIG. The relationship between the wall length of the cradle 2 and the length W of the electronic cassette 1 will be described. As shown in FIG. 4, the wall length L1 of the cradle 2 and the length W of the electronic cassette 1 satisfy the relationship of W> L1 and / or the wall height H of the cradle 2 and the electron The height Hy up to the center line Xc of the cassette 1 is configured to satisfy the relationship Hy> H. That is, the vertical length H of the first wall surface A and the second wall surface B is configured to be shorter than the half length Hy in the vertical direction when the electronic cassette 1 is stored, and / or Alternatively, the horizontal length L2 of the second wall surface C is configured to be shorter than the length Hx that is half the horizontal length when the electronic cassette 1 is stored. It is sufficient that at least one of these relationships is established.

  Considering the stability when the electronic cassette 1 is stored, the length L2 of the shorter wall is preferably at least half the length Hx of the electronic cassette 1 (L2> Hx). Thereby, even if the user holds and operates the vicinity of the central portion of the side of the electronic cassette 1, it is possible to prevent the user's hand and the cradle 2 from coming into contact with each other at the time of insertion / extraction, thereby improving the operability. Further, even if a plurality of cradle 2 for storing the electronic cassette 1 are installed adjacent to each other, the influence on the operability is small because the electronic cassette 1 can move within the range of the angle θ. Therefore, the installation space can be used effectively.

  As described above, according to the configuration of the first embodiment, a storage device that can effectively use the installation space even when there are a plurality of radiation imaging apparatuses (electronic cassettes) and has a good insertion / extraction operation of the radiation imaging apparatus ( Cradle).

  FIG. 5 is a plan view of a configuration in which the electronic cassette 1 according to the present embodiment is housed in the charging cradle 2 and two units are installed adjacent to each other when observed from above.

  The width (thickness) of the L1 length wall of the cradle 2 holding the electronic cassette 1 is D1, and the width (thickness) of the L2 length wall is D2. That is, the thickness of the first wall surface portion having the first wall surface A is D1, and the thickness of the second wall surface portion having the second wall surface C is D2. In addition, an angle when the electronic cassette 1 is inserted / removed is θ1.

  When L1> L2, the configuration is such that D1 <D2. On the other hand, when L1 <L2, the configuration is such that D1> D2. When L1> L2, tan θ1 = D2 / (L1−L2) and tan θ2 = (D1 + D2) / (W−L2). The dimensions are such that tan θ1 = D2 / (L1−L2) <tan θ2 = (D1 + D2) / (W−L2), that is, θ1 <θ2.

  In addition, it is desirable to have a dimension that satisfies θ1> 25 degrees, and when the electronic cassette 1 is attached or detached, the electronic cassette 101 is inserted and removed without contacting the electronic cassette 101 stored in the adjacent cradle even when the electronic cassette 1 is inclined. It becomes possible.
