CONSTITUTION: A portable information terminal equipment 32 transmits the characters and the pictures inputted to an input/display device 37 and the characters and the pictures stored in a memory from a radio transmission/ reception circuit which is the first communication means through an antenna 38 to the electronic board 31. The electronic board 31 composites the characters and the pictures received through the antenna 34 by the radio transmission/ reception circuit which is the second communication means housed in a housing part 35 with the characters and the pictures already displayed on the board surface 23 and displays them. Thus, written information and displayed information, etc., are mutually displayed between the electronic board 31 and the information terminal equipment 32.
