FIG. 1 is a perspective view illustrating an X-ray imaging apparatus as a radiation imaging apparatus according to the aspect of the present invention. In addition, referring to FIG. 1, only the first operation unit 31 out of the first operation unit 31 and the second operation unit 41 is mounted to the table 16.

[0033] Such X-ray imaging apparatus carries out an X-ray fluoroscopy or an X-ray imaging (hereafter, collectively X-ray imaging) comprises an X-ray irradiation element 13 that irradiates an X-ray to a subject on the table 16 supported by the supporting element 17 and an X-ray detection element 14 having an X-ray detector such as FPD (flat panel detectors) or II (image intensifier) and so forth that detects the X-ray transmitting through the subject. The X-ray irradiation element 13 and the X-ray detection element 14 are supported by C-arm 15 having the shape approximately as letter C. Such C-arm 15 is supported by a carriage 12 that shifts in one direction by that the guide element 11 fixed on the ceiling guide.

[0034] A rail 20 is installed on the side of the table 16. The rail 20 comprises the shifting element 21 having a lever 22 that is operative to shift horizontally and tilt, and in addition, to shift the C-arm 15 and the first operation unit 31 having a touch panel 32 (referring to FIG. 3) that is operative to display and input to execute inputting the operation relative to the X-ray image displayed on the display element 19. The table 16 is movable horizontally and tiltable according to the action of supporting element 17. In addition, referring to FIG. 1, the rail 20 shown only one side of the table 16, but each rail is respectively on both sides of the table 16.

[0035] In addition, such X-ray imaging apparatus comprises a display element 19 that displays the X-ray image acquired by the X-ray detection element 14. Such display element 19 comprises a plurality of monitors and hangs from the ceiling 18.

[0036] FIG. 2 is a side view illustrating the state in which the first operation unit 31 is mounted to the rail 20. In addition, FIG. 3 is a perspective view illustrating the first operation unit 31 and the second operation unit 41 together.

[0037] Such first operation unit 31 having the touch panel 32 that is operative to display and input to execute inputting the operation relative to the X-ray image displayed on the display element 19. Such touch panel 32 comprises a supporting element 35 on the backside thereof. The supporting element 35 is oscillable at the center of the axis 30 relative to the mounting element 36. In addition, the rail 20 is in-place between the mounting element 36 and the mounting auxiliary board 37 and the mounting element 36 and the mounting auxiliary board 37 sandwich and hold the rail 20 using a function of the screw 38. The mounting angle of the touch panel 32 relative to the rail 20 is adjustable by the operation of the second operation unit 41 installed to the bottom-side of the touch panel 32. Referring to FIG. 2, the first operation unit 31 comprises a first connection element 33 having the shape connectible with a second connection element 45 of the second operation unit 41, set forth later.

[0038] FIG. 4 is a side view illustrating the state in which the second operation unit 41 is mounted to the rail 20. FIG. 5 is a side view illustrating the state in which the second operation unit 41 is mounted to the rail 20. In addition, FIG. 6 is a schematic view illustrating the connection state between the first connection unit 33 in the first operation unit 31 and the second connection unit 45 in the second operation unit 41.

[0039] Such second operation unit 41 comprises the lever 42 that is feasible to change the tilting direction relative to the main body 44 to execute the input operation relative to X-ray image displayed on the display element 19 The second operation unit 41 comprises the mounting element 46 that locks and mounts the second operation unit 41 with the rail 20. The second operation unit 41 is mounted to the rail 20 by that the operator locks the mounting element 46 with the rail 20 while the operator is supporting the operation unit 43. Referring to FIG. 5, 6, set forth above, the second operation unit 1 comprises a second connection element 45, having the shape connectible with a first connection element 33 of the first operation unit 31, at the side thereof.

[0040] Referring to FIG. 6, with respect to the first connection element 33 of the first operation unit 31 and the second connection element 45 of the second operation unit 41, the second connection element 45 having the cross section of which shape is an approximately upside-down letter L is connected with the first connection element 33 having the cross section of which shape is an approximately letter L, so that the second operation unit 41 can be fixed to the first operation unit 31.
