Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a mount such as an X-ray machine used for taking X-rays when examining dogs, cats and other animals.

[0002]

2. Description of the Related Art For example, when an X-ray of a human body is to be taken, the X-ray machine is moved to the affected area and fixed, and then the patient himself or herself is aligned with the camera based on the instructions of a doctor or an X-ray technician. It is made to stop at this position.

[0003]

However, in the case of an animal, since it is not possible to perform the positioning and resting operations with respect to the photographing machine by itself, the affected part is manually positioned with respect to the photographing machine. However, such an operation is complicated and labor-intensive, and it is difficult to adjust the movement of a large animal in particular, which requires time and labor, and also causes problems such as heavy labor.

[0004]

The present invention has been made in consideration of the above-mentioned problems of the prior art, and has been made in consideration of the above-described problems, and it is an X-ray imaging apparatus capable of easily performing positioning and fixing (stationary) of an animal or the like with respect to an X-ray imaging apparatus. It is intended to provide a mounting table for the above.

[0005]

In order to achieve the above-mentioned object, a mounting table for an X-ray imaging apparatus or the like according to the present invention is constructed such that sliders fitted respectively are overlapped and fixed on a base to raise and lower a guide rail. In addition, and the interposition of a sliding frame formed by slidably arranged in the two axial directions mutually interposed, the underframe for placing an animal or the like is horizontally movably arranged in all directions, on the base, A pair of pinions each of which is pivotally supported by a slider of an upper guide rail in the slide mechanism, a slider of the upper guide rail, and a pair of racks each of which is fixed to the underframe in a biaxial direction. Tighten to each pinion shaft, tighten the fastener to the loosely exteriorized fastener,
It is characterized by providing a pinion lock mechanism by screwing a loosening lock shaft.

[0006]

With the pinion unlocked by the fastener, the animal is placed on the underframe and the underframe is moved. With the structure in which the guide rails are slidably arranged in the two axial directions of the slide mechanism, the underframe can freely move horizontally in the diagonal direction as well as in the two axial directions. In contrast, the positioning of the animal, that is, the affected part, becomes easy.

After the animal is positioned with respect to the X-ray machine, when each lock shaft is screwed in a predetermined direction, a screw shaft portion of each lock shaft is screwed into a screw hole of a fastening fitting. The fastening fitting is reduced in diameter by providing a slit, and the pinion shafts are tightened from the outer periphery. The pinion shafts are fixed, so that the pinions are fixed non-rotatably.

[0008] Of the pair of two pinions described above, one pinion is engaged with a rack fixed to the underframe in a single axial direction, and the other pinion is extended by a slider of the guide rail in a direction perpendicular to the rack. Since the pinion is engaged with the fixed rack, the underframe is locked without horizontally moving in any direction by fixing the two pinions. Therefore, since the animal can be stopped at the position where the animal has been registered in advance, X-ray imaging can be performed.
