It may be. Further, by touching a predetermined area of the window 12, the display state and the non-display state of the image may be switched, and the patient's oral cavity may be directly viewed through the window 12. Switching between display and non-display is the same for other windows. Further, the patient chart information displayed in the window 13 can be page-turned by a drag operation. Furthermore, an image such as an X-ray image in the window 14 that needs to be enlarged can be displayed in an arbitrary size in accordance with a pinch-in / pinch-out reduction / enlargement display operation.

  When the operation button indicated by the arrow displayed on the window 15 or the operation button of the window 16 is touched, the operated device can be operated according to each button. For example, by touching the arrow on the backrest portion of the chair displayed on the window 15, the backrest can be tilted or raised, and the display of the chair can be changed in accordance with this operation. That's fine. For example, when a light is touched with the operation button of the window 16, light emitted from a light source (not shown) provided on the light source 2 or the handpiece is sequentially irradiated with white light, infrared light, ultraviolet light, and non-irradiation. It can be made to switch in order. When the camera is touched, an image acquired from the imaging unit 3 can be displayed on a predetermined window.
