ここで、枠部１１０に器具本体１２０を固定する方法について説明する。
上述したように、枠部１１０は、枠部１１０の照射側の開口面より取付側に引っ込んだ位置に固定部１１４が形成されている。この固定部１１４の照射側の面と底面部１２５の裏側の面とを当接させて、ネジ止めすることにより、枠部１１０に器具本体１２０が固定される。具体的には、固定部１１４と底面部１２５との各々にネジ穴が形成され、底面部１２５の側から固定ネジで固定部１１４と底面部１２５とを重ねて固定する。よって、図１及び図２に示すように、枠部１１０の内部に器具本体１２０の取付側の一部が入り込む形で、底面部１２５が固定部１１４に固定される。なお、固定方法は、ネジ止め以外でもよく、ビス止め、あるいはフックのような係合部材を用いてもよい。
また、図３では、固定部１１４にはネジ穴１１４ａが１つ形成され、固定部１１４の１箇所で底面部１２５と固定されている。しかし、固定部１１４にネジ穴を２箇所以上形成し、固定部１１４の２箇所以上で底面部１２５と固定されていてもよい。また、固定部１１４は、短辺部１１２からだけでなく、長辺部１１１から内側に突き出るように形成され、底面部１２５と固定されてもよい。 Here, a method of fixing the instrument main body 120 to the frame portion 110 will be described.
As described above, in the frame portion 110, the fixing portion 114 is formed at a position recessed from the opening surface on the irradiation side of the frame portion 110 toward the mounting side. The instrument main body 120 is fixed to the frame portion 110 by bringing the surface on the irradiation side of the fixing portion 114 and the surface on the back side of the bottom surface portion 125 into contact with each other and screwing them together. Specifically, screw holes are formed in each of the fixing portion 114 and the bottom surface portion 125, and the fixing portion 114 and the bottom surface portion 125 are overlapped and fixed with fixing screws from the side of the bottom surface portion 125. Therefore, as shown in FIGS. 1 and 2, the bottom surface portion 125 is fixed to the fixing portion 114 so that a part of the mounting side of the instrument main body 120 enters the inside of the frame portion 110. The fixing method may be other than screwing, and screwing or an engaging member such as a hook may be used.
Further, in FIG. 3, one screw hole 114a is formed in the fixing portion 114, and the fixing portion 114 is fixed to the bottom surface portion 125 at one place. However, two or more screw holes may be formed in the fixing portion 114, and the fixing portion 114 may be fixed to the bottom surface portion 125 at two or more locations. Further, the fixing portion 114 may be formed so as to protrude inward not only from the short side portion 112 but also from the long side portion 111, and may be fixed to the bottom surface portion 125.
