X-RAY CT EQUIPMENT

PROBLEM TO BE SOLVED: To provide X-ray CT equipment dissolving trouble and stress of a doctor and an operator by improving the operability of a dial for adjusting parameters controlling a screen display of a tomogram. SOLUTION: An operation surface of the dial 63, in a position deflected from its rotating shaft, is provided with a recessed member 63a formed with a recessed part for applying a finger when rotatingly operating the dial 63, a bearing 63b supporting the recessed member 63a, and a bearing 63c rotatably supporting the bearing 63b relative to the body of a keyboard 6. This constitution can, when the doctor or the operator rotates the dial with the finger tip applied to the recessed part of the recessed member 63a, absorb the slide generated between the finger and the recessed member 63a by rotating the recessed member 63a so as to avoid slipping of the finger tip from the recessed member 63 during rotating the dial 63.
