The invention discloses that when parts are mounted on a single board in a plurality of identical patterns, parts mounting can be effieciently performed by changing the sequence of mounting the parts for each pattern in accordance with the arrangement state of the pattern, and a blank portion on the board can be minimized and hence patterning can be effectively performed by arbitrarily setting the directions of the mounting patterns to be mounted on the printed board in accordance with its form. In addition, the invention discloses that when chip parts are mounted on a board in a plurality of patterns including identical patterns and independent pattern having no correlation therewith, parts mounting can be easily and collectively performed, and when a plurality of types of parts having different shapes and sizes are mounted on a board together, a group of parts which are less subject to a positional error due to the movement speed of an X-Y table are repeatedly mounted first on the board at a high movement speed, and a group of parts which are subject to a positional error are repeatedly mounted in the same manner at a low movement speed, thereby preventing a positional error due to an inertial force upon high-speed movement of the X-Y table.
