PROBLEM TO BE SOLVED: To shorten the read-in time of edited data by storing divided pieces of edited data, and selecting and reading in object edited data. SOLUTION: In a video RAM(VRAM) 102, characters and images to be displayed on the screen of a CRT display device are expanded and stored. A bit move unit(BMU) 103 controls data transfer between memories or a memory and respective devices. A keyboard 104 has various keys for document editing, etc. Further, a RAM 108 is used as a work area when a CPU 106 executes various programs and a temporarily saving area for an error process. Then an edited document is divided logically into pieces of edited data, which are saved in the RAM 108; and object edited data is selected out of the stored pieces of edited data and read in the VRAM 102. |
