ABSTRACT:
Laser control apparatus for controlling a laser beam with respect to a working area to trace a desired pattern on a working area comprises an input device for inputting the desired pattern; a memory for storing a line pattern; a display for displaying the pattern; and a control system for controlling the laser beam. The control system comprises a Line-Operation selector and an Area-Operation selector, the Line-Operation selector being effective to cause the line pattern stored in the memory to be reproduced by the laser beam on the object, the Area-Operation selector being effective to cause the line pattern stored in the memory to be converted to an area pattern enclosing the area bounded by the line.
