<p>PURPOSE:To shorten the total processing time by decreasing the frequency of communication. CONSTITUTION:Screen information from another device is received at a time by an amount larger than the amount of information which can be displayed at a time and stored in a storage part 2. Information displayed on a screen display part 6 is instruction information or head information from another device and displayed immediately by a method approved with the device. An operator inputs an instruction for displaying plural planes of information on the display part 6 from an instruction part 3. Consequently, a control part 4 displays information required for a processing part 5 on the display part 6 from the storage part 2. Further, an instruction for the addition, alteration, or deletion of information is supplied while looking at the screen information and the information stored in the storage part 2 is added, altered, or deleted according to the instruction. Further, an instruction for sending a part or the whole of the information to the device is supplied when necessary. Consequently, the time required to send and receive the information is shortened on the whole.</p> |
