Abstract

A radiation imaging apparatus comprises a housing which encases an image conversion unit for converting radiation into an electrical signal relating to a radiation image, and has at least one opening formed thereon and a housing conductive portion at least a part of which is a conductive portion, a cover member arranged to cover the opening, which is detachably attached to the housing and comprises a cover conductive portion at least a part of which is a conductive portion; and an elastic member provided between the cover member and the housing, wherein the housing conductive portion and the cover conductive portion are pressed into contact by a reaction force of the elastic member.

Claims (49)

1. A radiation imaging apparatus comprising:

an image conversion unit configured to convert radiation into an electrical signal relating to a radiation image;

a housing arranged to encase the image conversion unit, on which at least one opening is formed and comprising a housing conductive portion at least a part of which is a conductive portion;

a cover member arranged to cover the opening, which is detachably attached to the housing and comprising a cover conductive portion at least a part of which is a conductive portion; and

an elastic member provided between the cover member and the housing,

wherein the housing conductive portion and the cover conductive portion are pressed into contact by a reaction force of the elastic member,

wherein the cover member is formed of a metal and is coated at least partially, and

wherein the cover conductive portion is a portion of the cover member that is not coated.

2. The radiation imaging apparatus according to claim 1 , wherein the cover member is formed of an aluminum alloy as the metal.

3. The radiation imaging apparatus according to claim 1 , wherein the housing is formed of a metal and is coated at least partially, and

wherein the housing conductive portion is a portion of the housing that is not coated.

4. The radiation imaging apparatus according to claim 3 , wherein the housing is formed of a magnesium alloy or an aluminum alloy as the metal.

5. The radiation imaging apparatus according to claim 1 , wherein a housing is formed of CFRP and has a three-dimensional structure, and

wherein the housing conductive portion is provided on an end of a vertical wall in the three-dimensional structure.

6. The radiation imaging apparatus according to claim 1 , wherein the housing includes an external appearance housing part having an exterior surface and the housing conductive part, and a holding housing part which has a recessed part capable of holding an electric component therein, fixed integrally with the external appearance housing part, and

wherein the elastic member is provided between the cover member and the holding housing part.

7. The radiation imaging apparatus according to claim 6 , wherein the electric component is a battery.

8. A radiation imaging apparatus comprising:

an image conversion unit configured to convert radiation into an electrical signal relating to a radiation image;

a housing arranged to encase the image conversion unit, on which at least one opening is formed and comprising a housing conductive portion at least a part of which is a conductive portion;

a cover member arranged to cover the opening, which is detachably attached to the housing and comprising a cover conductive portion at least a part of which is a conductive portion; and

an elastic member provided between the cover member and the housing,

wherein the housing conductive portion and the cover conductive portion are pressed into contact by a reaction force of the elastic member,

wherein the cover conductive portion is provided on one end of the cover member, the radiation imaging apparatus further comprising a locking mechanism disposed at an other end of the cover member opposite to the one end of the cover member and locking the cover member so as to be mounted on the housing by contacting the housing, and

wherein a distance between the cover conductive portion and the elastic member is shorter than a distance between a contact portion of the lock mechanism contacting with the housing and the elastic member.

9. The radiation imaging apparatus according to claim 8 , wherein the housing is formed of a metal and is coated at least partially, and

wherein the housing conductive portion is a portion of the housing that is not coated.

10. The radiation imaging apparatus according to claim 9 , wherein the housing is formed of a magnesium alloy or an aluminum alloy as the metal.

11. The radiation imaging apparatus according to claim 8 , wherein a housing is formed of CFRP and has a three-dimensional structure, and

wherein the housing conductive portion is provided on an end of a vertical wall in the three-dimensional structure.

12. The radiation imaging apparatus according to claim 8 , wherein the lock mechanism is formed integrally with the cover member.

13. The radiation imaging apparatus according to claim 8 , wherein the housing includes an external appearance housing part having an exterior surface and the housing conductive part, and a holding housing part which has a recessed part capable of holding an electric component therein, fixed integrally with the external appearance housing part, and

wherein the elastic member is provided between the cover member and the holding housing part.

14. A radiation imaging apparatus comprising:

an image conversion unit configured to convert radiation into an electrical signal relating to a radiation image;

a housing arranged to encase the image conversion unit, on which at least one opening is formed and comprising a housing conductive portion at least a part of which is a conductive portion;

a cover member arranged to cover the opening, which is detachably attached to the housing and comprising a cover conductive portion at least a part of which is a conductive portion; and

an elastic member provided between the cover member and the housing,

wherein the housing conductive portion and the cover conductive portion are pressed into contact by a reaction force of the elastic member,

wherein the cover conductive portion is provided on one end of the cover member, the radiation imaging apparatus further comprising a locking mechanism disposed at an other end of the cover member opposite to the one end of the cover member and locking the cover member so as to be mounted on the housing by contacting the housing, and

wherein the locking mechanism is formed of a conductor.

15. The radiation imaging apparatus according to claim 14 , wherein the housing is formed of a metal and is coated at least partially, and

wherein the housing conductive portion is a portion of the housing that is not coated.

16. The radiation imaging apparatus according to claim 15 , wherein the housing is formed of a magnesium alloy or an aluminum alloy as the metal.

17. The radiation imaging apparatus according to claim 14 , wherein a housing is formed of CFRP and has a three-dimensional structure, and

wherein the housing conductive portion is provided on an end of a vertical wall in the three-dimensional structure.

18. The radiation imaging apparatus according to claim 14 , wherein the lock mechanism is formed integrally with the cover member.

19. The radiation imaging apparatus according to claim 14 , wherein the housing includes an external appearance housing part having an exterior surface and the housing conductive part, and a holding housing part which has a recessed part capable of holding an electric component therein, fixed integrally with the external appearance housing part, and

wherein the elastic member is provided between the cover member and the holding housing part.
