PROBLEM TO BE SOLVED: To solve the problem that although handles can be also turned toward the side of roentgenographic equipment for round of visits by rotating an X-ray movable iris by 180 degrees when they are employed with attaching to mobile type roentgenographic equipment and a front section is arranged with approaching the wall of a ward, etc. although the handles of adjusting the irradiation range of X rays are attached to a front section so that they may be easy to operate in the X-ray movable iris, usually operation for them is not easy and moreover it is necessary to slack a cable connected to the X-ray movable iris for that purpose to be a hindrance to operation.SOLUTION: The vertical opening and closing handle 7 and the horizontal opening and closing handle 8 are attached to the front of the X-ray movable iris 51 and the vertical opening and closing handle 47 and the horizontal opening and closing handle 48, in which a direction of turning the handles and the placement of the handles are the same as the vertical opening and closing handle 7 and the horizontal opening and closing handle 8 in the front, are also formed in the rear surface.COPYRIGHT: (C)2009,JPO&INPIT【課題】X線可動絞りにおいて、X線の照射範囲を調整するつまみは操作しやすいように前面部に取り付けられているが、移動式X線撮影装置に取り付けて使用して、前面部が病室の壁等に近接して配置された場合、X線可動絞りを180度回転させてつまみを回診用X線撮影装置側に向けることもできるが、通常そのための操作は容易ではなく、またそのためにはX線可動絞りに接続されるケーブルをたるませておく必要があり操作の邪魔になる【解決手段】縦開閉つまみ7および横開閉つまみ8をX線可動絞り51の前面にとりつけるとともに、後面にもつまみを回す方向およびつまみの配置が前面の縦開閉つまみ7および横開閉つまみ8と同じである縦開閉つまみ47および横開閉つまみ48を設ける。【選択図】 図1
