PROBLEM TO BE SOLVED: To provide a system for automatically updating program data for smoothly distributing program data while suppressing the increase of the load of processing to be performed by a device which supplies the program data, and for correctly completing the supply of the program data at the scheduled date. SOLUTION: When a control center controller 100 updates program data, a control center storage device 110 stores the program data. Acquiring/ distributing devices 120-1-120-n respectively inputs the acquiring date of the program data and the distributing date to a terminal, and when the acquiring date is prior to the present date by prescribed hours or more, and the distributing date is posterior to the acquiring date by the prescribed hours or more, the inputted acquiring date and distributing date are stored. Then, when the acquiring date stored by its own device comes, the updated program data are acquired from the control center 110 through a communication line, and when the distributing date comes, the updated program data are distributed to each terminal in a facility where its own device is set.
