PROBLEM TO BE SOLVED: To provide a CT apparatus with which positional information about the operation object of a display part is easily recognized when an operator operates the apparatus from an operation part by varying, that is, emphasize-displaying the display mode of the display part so as to characterize the positional information about the operation object according to the operation from the operation part. SOLUTION: Operation content at the operation part 21 is sent to a controller 24 as a switch signal. The controller 24 transfers this signal to a control part 30 and sends a luminance change instruction signal to a luminance change circuit 25 so as to change the luminance of the part of the display part 22 corresponding to the switch signal. In order to change the luminance of a part corresponding to the display part 22 according to the luminance change instruction signal, the luminance change circuit 25 adjusts a current value supplied to a 7-segment LED (light emitting diode) unit 220 constituting each display part 22 (22a to 22d) e.g. with variable resistance to change the luminance.
