PURPOSE:To shorten the waiting time for terminal operations by using a processing order controller which holds plural command data given from an input device and at the same time controls the input order of those command data to a graphic data processor in accordance with the types of said command data. CONSTITUTION:The plural command data are supplied en block into a processing order controller 2 from an input device 1. At the same time, a graphic data processor 5 processes continuously those command data in response to their priorities so that no conflict occurs when each of said command data is carried out by the controller 2. Thus the circuit using frequency is reduced even in such a case where the terminal of a time sharing system using a communication circuit having a comparatively low data transfer speed is used as the device 1, a display device 7, etc. As a result, the waiting time is shortened for an editing operation of the graphic data carried out at a terminal.
