There is no possibility that it will happen. Therefore, even a soft object can be accurately positioned.

Furthermore, the indicating device of the second invention uses a mechanism capable of color display, spot display, and area display, such as plasma display, liquid crystal display, and electroluminescence* two-dimensionally arranged light emitting diodes, as an optical two-dimensional display mechanism. Because it is used, color display, spot display, and area display are possible. Therefore, workability is further improved.

Furthermore, since the pointing device of the fifth invention uses a light-emitting element with high emission intensity as the optical two-dimensional display mechanism, it is possible to point out the position of even a pointed object with low light transmittance.
