The top plate moving button 26 is, for example, a button that raises the top plate when the top plate 6 is below the height of the top plate desired by the operator (height of the operator's waist). When the top plate 6 is above the height of the top plate desired by the operator, the top plate 6 is composed of a button for lowering the top plate so that the operator can press any button depending on the situation. It has become. The moving mechanism 25 is provided with a detector 27 that constantly detects, for example, the number of rotations of a motor for moving the top plate 6, and when the top plate 6 is moved by driving the moving mechanism 25. Based on the output from the detector 27, a value corresponding to the height of the top plate 6 is calculated by the calculation mechanism 28, and information corresponding to this value is input to the comparison device 29.

  Information corresponding to the waist height of the operator who operates the X-ray imaging apparatus is input from the storage device 24 to the comparison device 29. The comparison device 29 receives the information from the detector and the detector. A comparison is made with a value corresponding to the height of the top plate. In the comparison device 29, in the comparison between the information corresponding to the height of the operator's waist and the value corresponding to the height of the top plate, it is determined by the matching determination means 30 whether or not the matching is made.
