A sewing machine has a sewing head which includes a needle bar drive mechanism for vertically reciprocally moving a needle bar, a presser foot drive mechanism operable to vertically move a presser foot in synchronism with the vertical movement of the needle bar, a direction control mechanism operable to pivot the presser foot about the needle bar for controlling a direction of the presser foot to a predetermined direction, and a guide member drive mechanism operable to reciprocally pivot a guide member. The guide member is adapted to guide a cord-like material to be sewn on a work. The presser foot drive mechanism, the direction control mechanism and the guide member drive mechanism have a first drive source, a second drive source and a third drive source, respectively, provided independently of each other.
