Abstract

PURPOSE:To improve handleability by receiving picture information by plural radio receivers and displaying the information on plural display means. CONSTITUTION:Picture information data in a floppy disk set to a personal computer 1 are successively read out and transmitted by a radio receiver 3. On the other hand, since radio receivers (4-1)-(4-8)are connected to portable display terminals (2-1)-(2-8), the picture information data transmitted from the radio receiver 3 are passed through the radio receivers and received at the respective portable display terminals(2-1)-(2-8), and the same picture is displayed at the respective display terminals. Thus, workability can be improved for construction.
