トボード。[Scope of Claim for Utility Model Registration] In a whiteboard in which an overhead projector (OHP) is arranged on the surface of the board so that the light emitted from the overhead projector (OHP) can be focused on the surface of the board, so that it can be scanned by scanner 4 along
The scanner 4 has a light transmission hole 4b that transmits the light emitted from the overhead projector (OHP), and the optical sensor 4a detects the transmission path of the light emitted from the overhead projector (OHP). A white system that focuses the light projected from an overhead projector on the surface of the board, characterized by the fact that it is tilted in a direction that allows the projection image formed on the surface to be photographed at a position that is avoided. board.
