ABSTRACT:
A buttonhole sewing machine includes a holding mechanism attached to a holder arm which reciprocates in a direction perpendicular to an amplitude direction of a needle. The holding mechanism includes a workpiece holder plate and constitutes a parallelogram linkage. The holding mechanism maintains a parallelogram shape even when the holder plate slants on a fold of the workpiece, and securely holds the workpiece. This buttonhole sewing machine also includes a cutting mechanism which cuts thread and braid in a short manner even when the holder plate slants. The cutting mechanism has a rotary cutter and a fixed cutter, and the fixed cutter is fixed on the holder plate while inclined from a proximal portion to a distal portion. A wire member is connected to the mobile cutter to facilitate the rotation of the rotary cutter even when the holder plate slants.
