Identification information 5 is recorded at the peripheral part of the picture display face. Then, x/y-coordinate information layers showing coordinate information on the picture display face 6 are formed at the lower part of the picture display face. A pen-type information input/output device 3 has a light reception/emission part detecting identification information 5 for identifying the information display medium 2 and detecting the coordinate information. Detected identification information 5 and the coordinate information are associatively processed and are stored in a memory. Then, they are transmitted to a personal computer. |
