SYSTEM FOR CONTROLLING COOPERATIONS AMONG A PLURALITY OF TERMINALS CONNECTED TO A NETWORK WHEREBY EACH TERMINAL CAN BE SWITCHED FROM COOPERATIVE TO INDIVIDUAL OPERATION MODE

Each of a plurality of terminals includes a processing section, a cooperation controlling section and an inputting section. The inputting section inputs, to the cooperation controlling section, input data and switching data for switching over a cooperative operation mode and an individual operation mode. The switching section switches over the cooperative operation mode and the individual operation mode on the basis of the switching data given from the inputting section. The self-input processing section supplies, when in the cooperative operation mode, the input data from the self-inputting section to the self-processing section and other processing sections which should operate in cooperation and supplies, when in the individual operation mode, the input data from the self-inputting section to the self-processing section. The cooperation input processing section supplies, when in the cooperative operation mode, the self-processing section with input data from other processing sections but supplying, when in the individual operation mode, the self-processing section with no input data from the other processing section.
