Abstract
A needle bar case has a plurality of needle bars. As a main shaft is rotated by a main shaft motor (first drive source), the needle bars are driven in an up-down direction so that a sewing operation is carried out in a conventionally-known manner. Ascending/descending bars are supported on the needle bar case in corresponding relation to the needle bars, and each of the ascending/descending bars is driven in the up-down direction by a motor (second drive source). A cord guide member for guiding a cord material onto a workpiece is mounted to the lower end of any of the ascending/descending bars, in place of a conventional presser foot. Cord sewing or loop sewing of cord material can be performed selectively by changing an ascending/descending stroke of the ascending/descending bar. Thus, cord sewing and loop sewing of the chord material can be performed selectively with a simple construction.
