PURPOSE: To display plural sets of sufficient information by providing plural communication display units each comprising a communication equipment, an operation device operating the communication equipment and plural display devices each making data communication via the communication equipment and a radio transmission channel so as to connect the communication equipment via a wired system network. CONSTITUTION: When an operation device 30 is used to raise a communication equipment 20 at first, a radio transmission channel and a wired system network 40 are connected, and, e.g. a display device 10 is raised to execute an application recorded in an internal RAM and a desired job pattern is outputted. Similarly plural display devices 10 are raised sequentially. When information exchange with the communication equipment 20 of other communication display unit is required during a job, data are sent/received via the radio transmission channel. When data communication is required between the display devices 10, data are once sent to the communication equipment 20 via a radio transmission channel 32 and to other display devices 10 through radio LAN intermission control of the communication equipment 20 via the radio transmission channel. Furthermore, when information exchange with other communication equipments on a wired system network 40 is required, data are sent/received via a communication control section of the network 40. LAN control information for the communication equipment 20, the network 40 and the radio system LAN is displayed on the operation device 30. |
