PROBLEM TO BE SOLVED: To provide an inter-terminal interlocking system where the load of a main machine is minimized when the updating information processed by the main machine is reflected on all other machines. SOLUTION: When the updating requests are simultaneously transmitted to a main machine 1 from the machines 2a, 2b and 2c which want to update their contents, the machine 1 performs the updating processing based on the request of the machine 2a and sends the updating information, i.e., the updating processing result to the machine 2a. In the same way, the machine 1 also performs the updating processing to the requests of machines 2b and 2c and sends the processing results to them. Receiving the updating information from the machine 1, the machine 2a sends the updating information to six terminals in six messages respectively. So is with the processing of machines 2b and 2c.
