Abstract
A sewing machine comprises a feeding device which moves between the under position of the cutter apparatus and the under position of the needle bar with a work piece which is set on the feeding device such that the buttonhole slit is formed on a desired position, a setting signal transmitter for transmitting a complete signal when the work piece is set on the feeding device, and a post-buttonhole slit method indicator for indicating the post-buttonhole slit method in order to form the buttonhole slit by the cutter apparatus after buttonhole stitches are formed by the cooperation of the needle and the looper. When the post-buttonhole slit method is indicated by the post-buttonhole slit method indicator, the feeding device moves under the needle bar and the feeding device is controlled so as to stay under the needle bar until the setting signal transmitter inputs the complete signal.
