Title:
SYSTEM FOR AUTOMATICALLY DESIGNING PRINTED BOARD PATTERN
Document Type and Number:
Japanese Patent JPS59109971
Kind Code:
A
Abstract:
PURPOSE:To set a rand inhibted area for a fixed area around the center of a through hole based on the coordinate, by discriminating the coordinates of positions in the inhibited area, and, when the next indicated coordinate is in the inhibited area, to make the indication invalid. CONSTITUTION:At the time of installing through holes 4 (A-c) to a printed board 1 from the surface to the back, a designer indicates the position of the through holes 4 with a write pen. A rand inhibited area D is installed for a fixed area around the center of the through holes 4 based on the coordinate and whether an indicated coordinate is in the inhibited area D or not is discriminated by a discriminating circuit. When a coordinate indicated by a designer with the write pen is in the inhibited area D, the indication is made invalid and erased, so that the operation of a printed board automatically designing system becomes easier.
