PURPOSE:To draw up a smoothly connected ruled line by performing inversional process of ruled line data against a pseudo-connection pattern drawn by an exclusive OR processing section in accordance with the information of an inversional area stored in an inversional area storage section. CONSTITUTION:Operators select various mode of a ruled line to be drawn up from an SW panel 6. Then necessary information is fetched from a ruled line information data memory 7 in accordance with an appointed mode and the inversional area of the ruled line data at the connecting part of the ruled line is operated at an arithmetic section 8. The result of this operation is sent to and stored in an inversional area storage section 9. On the other hand, an exclusive OR processing section 10 operates a signal corresponding to a pseudo-connection pattern and outputs the signal to an inversion processing section 11. At the processing section 11, inversional processing on the ruled line data is performed against the pseudo-connection pattern drawn by the processing section 10 in accordance with the information related to the inversional area stored in the storage section 9, and a smoothly connected ruled line is drawn up. The ruled line is displayed on a CRT12. |
