Communication controlling device, communication controlling method and image forming system

摘要

A communication controlling device includes a communication controller having a plurality of data receiving sections for carrying out data communication by using a plurality of communication tools having different communication systems from each other, the communication controller controlling each operating condition of the plurality of communication tools; and a supervisory controller for previously judging whether a received data received by the communication controller is valid and for specifying one communication tool through which data should be continuously transmitted. A data storage stores the received data which is judged to be valid. An access controller controls operating conditions of the supervisory controller and the data storage. The access controller also controls an operating condition of the communication controller so that the data is continuously transmitted through an effective communication tool for the received data which is previously judged to be valid.
