装置。By swinging a column, on which a film holder is supported at one end and an X-ray source at the other end, with its longitudinal intermediate portion as a fulcrum, the focal point of the X-ray source and the center of the film holder are supported. In a tomography apparatus configured to move the X-ray source and the film holder in parallel in opposite directions while maintaining a constant distance from the film, a rotating mechanism converts the rotational motion of the rotating mechanism into linear motion. a column drive mechanism comprising a rotation → linear motion conversion mechanism and a connecting member connecting the motion conversion mechanism and the column; and a speed control device that controls the column swing speed by giving a predetermined speed control command to the rotation mechanism. A column swinging device for a tomography apparatus, comprising:
