It has a device that protrudes toward the arm placement direction.

  In the embodiment, as shown in the drawing, at the lower part of the carriage 4, there is one auxiliary leg 17 having the carriage width direction as a longitudinal direction and both ends as a grounding portion 16, and this one auxiliary leg 17 in the carriage width direction. The apparatus main body to which the arm 6 is directed in accordance with the movement of the arm 6 that is pivoted toward the side of the apparatus main body 5 with the support section 18 that is movably supported and the auxiliary leg 17 supported by the support section 18. 5 is provided with a motion conversion mechanism unit 19 that feeds out to the side of 5.

  The auxiliary leg 17 has a length shorter than the carriage width. If the auxiliary leg 17 moves in the carriage width direction by supporting the auxiliary leg 17 so that the auxiliary leg 17 is movable, one of the grounding parts is provided. Advancing to the side of the carriage 4 with 16 as a tip, the auxiliary leg 17 protrudes.

  The above-mentioned motion conversion mechanism unit 19 can move the rotational motion of the rotating body that rotates in conjunction with the turning of the arm 6 by the support of the support unit 18 in the cart width direction. This is a part in which a mechanism for converting the leg 17 into a linear movement motion that feeds the arm 17 toward the arm arrangement direction is configured, and the device that the arm 6 faces according to the movement of the arm 6 as described above by interposing this mechanism part.

Is provided.

  When the arm 6 is turned to the side of the device and the auxiliary leg 17 is extended to the side of the device, the grounding portion 16 on the side of the auxiliary leg 17 protruding to the side of the device is rotated to lower the lower end 16a of the grounding 16. It is only necessary to rotate the arm 6 so as to face the floor, and this makes it possible to minimize the inclination of the device when the arm 6 is turned to the side of the device. If grounding of the grounding part 16 becomes unnecessary, it is easy to prevent unnecessary contact between the grounding part 16 and the floor surface by rotating the lower end 16a away from the floor surface.

  In the illustrated grounding portion 16, the lower end 16 a is formed flat, and when the grounding portion 16 is standing, the X-ray imaging apparatus 1 for the round visit is slightly inclined, and the lower end 16 a of the grounding portion 16 is Even if it hits the floor surface, the ground surface 16 is provided so as not to rotate by receiving the floor surface with the flat surface of the lower end 16a. It should be noted that it is only necessary that the grounding portion 16 does not rotate when the grounding portion 16 in a standing state hits the floor surface, and the lower end 16a is not necessarily flat.

  Further, in the above-described embodiment, the motion conversion mechanism unit 19 is rotated by the rotation gear 20 at the lower end of the rotation center shaft 13 a according to the turning operation of the arm 6, and this rotation rotation gear 20 meshes with the auxiliary leg 17. Although the auxiliary leg 17 is shown as linearly moving outward in the cart width direction, the motion conversion mechanism is not limited to the example in this embodiment, and the rotation portion is rotated by turning the arm. A well-known configuration in which the movement is converted into a linear movement movement of the auxiliary leg by a link can be employed.
