Abstract
A sewing machine translates a stitchwork frame with which a cloth is fastened along a direction of a plane where the cloth is fastened based on stitchwork data to form a stitchwork pattern. A presser foot located above the cloth has a height changed by an actuator like a stepping motor in accordance with the advancement of a stitchwork formation. Hence, a predetermined clearance between the cloth and the presser foot is maintained.
