<p>PURPOSE:To tabulate plural tables simultaneously by providing memory units which can store plural-page table data to be displayed on a display device. CONSTITUTION:A computational expression memory 3 can store computational expression data on three kinds of tables separately in computational expression memory units 3- I , 3-II and 3-III. An item data memory 5 can store each item data on three-page tables separately in item data memory units 5- I , 5-II and 5-III. A ruled line bit map memory 7 can store ruled line information on three- page tables separately in ruled bit map memory units (control information) 7- I , 7-II and 7-III. These respective memory units can store plural-page tables and select freely by a page selection circuit 8. Therefore, correction, computation and display of plural-page tables or display of the computational expression are easily performed in parallel.</p> |
