  The screen switching unit 53 determines whether to switch the screen based on, for example, whether a predetermined key of the operation unit 11 is pressed by the user (step S16).

  If the screen switching unit 53 determines in step S16 that the predetermined key has not been pressed, the process returns to step S14 to maintain the display state of the normal screen.

  On the other hand, when the screen switching unit 53 determines in step S16 that the predetermined key has been pressed, the normal screen display is switched to the full screen display.

  That is, the full screen display control unit 52 executes display control for displaying the measurement result screen on the display area 41a of the display unit 41 (step S17), and the floating display control unit 52a displays the measurement result displayed on the full screen. The operation panel image 64 is displayed in a floating manner on the screen.

  The display unit 41 displays the measurement result screen on the full screen in the display area 41a according to the display control of the full screen display control unit 52, and displays the operation panel image 64 in a floating manner (step S18).

  As described above, the measurement apparatus 10 according to the present embodiment can display the result display area 63 for displaying the measurement result on the display area 41a of the display unit 41, so that the visibility of the measurement result can be improved.

  In addition, since the measurement apparatus 10 according to the present embodiment displays the operation panel image 64 in which a command related to the measurement operation can be input in the result display area 63 displayed on the full screen, the measurement can be performed without impairing the operability related to the measurement.
