In many cases, an overhead support device is used that can support, move over a wide range, and position at a predetermined position. However, when treatment other than photography is performed in the installation room (photography room) 5, and when the affected animal enters and exits the installation room 5, because the affected animal is a large animal that cannot communicate verbally, unlike the patient. , care must be taken to prevent interference between the support device and the affected animal, and the support device becomes a nuisance.

In the conventional device, when the support device is not needed, the support device main body 3 of the X-ray tube device 7 is evacuated to a corner of the installation room 5, as shown in FIG. Interference was unavoidable. For this reason, there are cases in which the ceiling of the installation room is made high, and when the support device is not needed, the support device is raised to a position where it does not interfere with the affected animal. However, with this method, the vertical movement stroke of the support device becomes large, which not only increases the size of the entire device, but also requires large-scale construction of the installation room itself due to the high ceiling, which raises the problem of increased equipment costs. Ta.

An object of the present invention is to provide an overhead traveling type support device for a photographing device, which does not obstruct the support device at all when the support device is not needed, and which can downsize the entire device and simplify construction. The object of the present invention is to provide a mechanism for evacuation to the outside of the installation room.

[0006]

[Means for Solving the Problems] In order to achieve the above object, the present invention provides an evacuation movement rail for moving the main body of a support device for an imaging device such as an X-ray tube device from an installation room to an evacuation position outside the installation room. There is.

[0007]

[Operation] In the present invention, when the support device is not needed, such as when treating a patient or entering or leaving the installation room, the main body of the support device is moved from the installation room to a retracted position outside the installation room along the evacuation movement rail. This makes it possible to isolate the support device itself when the support device is not needed, completely eliminating the problem of the support device getting in the way, and compared to techniques that raise the ceiling of the installation room. The entire device can be made smaller and the construction work can be simplified. When the support device is needed, the support device main body is reintroduced into the installation chamber along the evacuation movement rail, set at a predetermined position, and then photographed.
