摘要:
A sewing machine including a sewing needle which conveys a needle thread; a needle bar which supports the sewing needle; a driver which generates a drive force; a first transmission mechanism which transmits the drive force of the driver to the needle bar so as to reciprocate the sewing needle in an axial direction of the needle; a work-sheet presser foot which is movable parallel to the needle bar; a needle thread take-up lever which takes up the needle thread conveyed by the sewing needle; a take-up-lever support member which supports the needle thread take-up lever, the take-up-lever support member being pivotable about a fixed axis line by being driven by the driver, for oscillating the needle thread take-up lever; and a second transmission mechanism which is independent of the needle bar, and transmits the pivotal motion of the take-up-lever support member to the presser foot so that the presser foot reciprocates in relation with the oscillation of the needle thread take-up lever.
