PROBLEM TO BE SOLVED: To provide X-ray equipment allowing an operator to confirm the type of an X-ray filter inserted in X rays based on the state of lighting of a display lamp and to obtain an excellent image under an appropriate X-ray condition by always selecting an optimum X-ray filter.SOLUTION: A control circuit 64 stores output values (A, B, C and D) of a position sensor 74 when a round hole 69a and the center of each X-ray filter 70, 71 or 72 are inserted in X rays. When the operator presses a selector switch 62, the control circuit 64 rotates a motor 67 via a motor driving circuit 66 and stops the motor 67 when the output value of the position sensor 74 reaches one of the values A, B, C and D. The control circuit 64 determines the frequency of 0.3-second switching on and 0.3-second switching off of the display lamp 63 according to the output value. This blinking is repeated every 3 seconds. |
