ABSTRACT:
A radiographic apparatus includes a C-shaped arm for supporting an X-ray tube at one end thereof and an image receiving unit at the other end, and an arm holder for slidably supporting the C-shaped arm for rotation about a center of an arc thereof. The arm holder has a hollow shaft supported therein to extend substantially parallel to an axis of the center of the arc, and a take-up drum supported on the hollow shaft. A drum drive device is operable in response to rotation of the C-shaped arm to rotate the take-up drum. A plurality of cables are connected to the X-ray tube and the image receiving unit, respectively. The cables are gathered into a bundle adjacent the X-ray tube or the image receiving unit, the bundle being guided by an outer periphery of the C-shaped arm to be wound on the take-up drum. The bundle further extends through the take-up drum and the hollow shaft into and then out of the hollow shaft.
