    摘要： A sewing machine including an input unit that inputs a thread cut instruction; a thread cutting mechanism that cuts a needle thread and a bobbin thread based on the thread cut instruction; a feed dog vertically moving mechanism that vertically drives a feed dog for feeding a workpiece cloth; a feed dog activating switch unit that switches the feed dog between an active state in which the feed dog is vertically driven by the feed dog vertically moving mechanism and an inactive state in which an upper surface of the feed dog is positioned in a lowered position below an upper surface of a needle plate provided in a sewing machine bed; and a control unit that drives the thread cutting mechanism based on the thread cut instruction inputted from the input unit and that controls the feed dog activating switch unit to switch the feed dog to the inactive state in which the feed dog is positioned in the lowered position.

    摘要： A device for operating several sewing functions is provided with a single control disk with curved paths arranged peripherally and facially on the control disk for acting radially and axially. The control disk is driven by a stepper motor and allows individual or several functions to be executed during the rotary movement as well as temporarily stopping others.

    摘要： A new and improved portable zigzag straight stitch walking foot sewing machine comprising a longer needle stroke, a larger presser foot having a radiused bottom, a throat plate having a larger opening therein, an inner presser foot having a relatively high lift permitting the easy insertion or removal of fabric which a new and improved spring loaded connecting rod that operates to prevent the fabric from being drawn into the presser foot opening and feed mechanism. In a specific embodiment, the new and improved portable zigzag straight stitch walking foot sewing machine includes a new and improved throw mechanism which is not biased and a retro fix stop device for reproducibly controlling the stitch length.
