| abstract | (57) [Summary] [PROBLEMS] To provide a writing recording system capable of reducing misreading of a signal and accurately detecting coordinates. SOLUTION: A surface 102 of a writing medium 100 is formed using an ultraviolet absorbent, and a lattice pattern 101 is printed on the surface 102 of the writing medium 100 with an invisible ultraviolet fluorescent ink. Accordingly, in the ultraviolet region, the surface 102 of the writing medium 100 is detected as a dark color due to the action of the ultraviolet absorber, and noise due to reflection from the surface 102 of the writing medium 100 is reduced even when sufficiently strong light is irradiated. Therefore, the difference in the fluorescence intensity between the surface 102 of the writing medium 100 and the lattice pattern 101 can be increased compared to the case where the surface 102 of the writing medium 100 is not formed using an ultraviolet absorber. , It is possible to reduce misreading of signals and the like, and coordinate detection can be performed accurately. |
