To provide a holding sewing machine capable of increasing the resolution of the distance between two needle location points aligned nearly in the fabric feeding direction of holding stitches and more finely setting the stitch density of the holding stitches.
This holding sewing machine sets a plurality of parameters specifying the size and shape of holding stitches, and a fabric feeding mechanism and a sewing mechanism are controlled by a control device based on the set parameters. In the setting of the parameters, a first fabric feed pitch b1 corresponding to the needle swing in one direction in needle swinging directions and a second fabric pitch b2 corresponding to the needle swing in the other direction are individually set as the fabric feed pitches of holding stitches so that the resolution Br of the distance B between two needle location points aligned in the fabric feeding direction can be increased.
