PROBLEM TO BE SOLVED: To improve operability by recognizing that switching operation is started and switching request is normally processed at the time of switching operation start by detecting the end of seamless angle switching processing. SOLUTION: When there is angle switching processing, a main controller 212 instructs a tube surface display device 213 to start displaying the start of seamless angle switching processing. At the same time as angle switching processing, the main controller 212 commands a data processor 201 to reads a navigation pack from data inputted through the data processor 201 to a track buffer 202 at that time, and its time information is reported to the main controller 212. When the obtained seamless angle switching processing is ended, and tube surface display device 213 is instructed to stop displaying the start of seamless angle switching processing. |
