Radiation irradiation apparatus

1. A radiation irradiation apparatus comprising:

a radiation source that irradiates, with radiation, a subject to be examined;

a photography unit that obtains a photographic image of the subject to be examined by performing photography on the subject to be examined;

a display unit that displays the photographic image;

a housing that houses the radiation source, the photography unit and the display unit with a display direction of the photographic image directed in a second direction opposite to a first direction that is an irradiation direction of the radiation and a photography direction of the photographic image; and

a plurality of grasp units that project in directions different from the first and second directions and are attached to positions of the housing facing each other.

2. The radiation irradiation apparatus, as defined in claim 1 , wherein the plurality of grasp units project in directions orthogonal to the first direction.

3. The radiation irradiation apparatus, as defined in claim 1 , wherein the display unit comprises a touch-panel-type input unit.

4. The radiation irradiation apparatus, as defined in claim 3 , wherein the display unit displays a setting menu based on a state of touch on the input unit.

5. The radiation irradiation apparatus, as defined in claim 4 , wherein the display unit displays the setting menu at a touch position on the input unit or in the vicinity of the touch position.

6. The radiation irradiation apparatus, as defined in claim 4 , wherein the setting menu includes a plurality of commands, and the display unit arranges and displays the plurality of commands at the touch position or in the vicinity of the touch position.

7. The radiation irradiation apparatus, as defined in claim 6 , wherein the input unit receives, by successive taps on a command, selection of the command successively tapped.

8. The radiation irradiation apparatus, as defined in claim 1 , further comprising:

a motion amount detection unit that detects a motion amount of the radiation source per unit time; and

a radiography permission unit that permits output of the radiation from the radiation source in the case that the motion amount has become less than a threshold.

9. The radiation irradiation apparatus, as defined in claim 1 , wherein the grasp unit includes two projection units projecting from the housing and a connection unit connecting the two projection units together, and a hole is formed by the two projection units, the connection unit and the housing.

10. The radiation irradiation apparatus, as defined in claim 1 , wherein the grasp unit is inclined or curved toward the second direction from its projection position.

11. The radiation irradiation apparatus, as defined in claim 1 , wherein the grasp units are detachably attached to the housing.

12. The radiation irradiation apparatus, as defined in claim 11 , further comprising:

an output permission unit that permits output of the radiation from the radiation source only if the grasp units are attached to the housing.

13. The radiation irradiation apparatus, as defined in claim 11 , further comprising:

attachment units that can attach, to the housing, the grasp units the projection amounts of which from the housing are different.

14. The radiation irradiation apparatus, as defined in claim 1 , wherein projection amounts of the grasp units from the housing are changeable.

15. The radiation irradiation apparatus, as defined in claim 1 ,

wherein the photographic image is an infrared image, and

wherein the display unit displays the infrared image and a radiographic image of the subject to be examined.

16. The radiation irradiation apparatus, as defined in claim 1 , wherein the display unit is detachable from the housing.

17. The radiation irradiation apparatus, as defined in claim 1 , wherein the display unit displays a setting menu based on the state of use.
