Abstract
An electronic sewing machine capable of sewing a buttonhole having a circular stitching part. The machine is operative selectively in one of automatic and manual modes. In the automatic mode, bight position of a needle and feed position of a feed dog are automatically controlled according to stored bight and feed data. In the manual mode, the bight and feed positions determined by the stored data are adjusted by a data adjusting circuit. The machine comprises a circuit which supplies the data adjustment circuit with a signal to inhibit the adjustment of at least the feed data for each stitch to be formed in the circular stitching part.
