Abstract
A sewing machine includes a needle bar reciprocally movable up and down, a thread take-up lever reciprocally swingable up and down, a thread supply which supplies a needle thread to the needle bar carrying the sewing needle, a plurality of thread guides including the thread take-up lever, an automatic threading apparatus automatically carrying the needle thread extending from the thread supply and passing the needle thread through the thread guides including the thread take-up lever, a first preparatory path formed for threading so that the needle thread extending from the thread supply can be passed through the thread guides by the automatic threading apparatus, and a second preparatory path formed for threading so that the needle thread extending from the thread supply can manually be passed through the thread guides, The thread take-up lever is displaced within a range of reciprocal swing so that threading is possible for at least one of the first and second preparatory paths.
