摘要： A sewing machine capable of sewing a manually moved workpiece cloth in free motion includes a carrier that carries the workpiece cloth and being manually moved to move the workpiece cloth; a support element that movably supports the carrier; a movement amount detector that detects an amount of carrier movement; a specifier that specifies a stitch pitch; a comparator that produces a comparison of the amount of carrier movement with the stitch pitch; a regulator provided at the support element and that regulates carrier movement; and a controller that controls the regulator such that the amount of carrier movement does not exceed the stitch pitch based on the comparison produced by the comparator.

摘要： A sewing machine capable of mode switching between a normal sewing mode and a free motion sewing mode including a feed dog switcher that switches a feed dog between an active state in which the feed dog is moved above and below a needle plate and an inactive state in which the feed dog is lowered below the needle plate, a first instruction issuer that instructs execution of fastening stitching at a beginning of pattern sewing sequence, a second instruction issuer that instructs execution of fastening stitching at an end of pattern sewing sequence, and a controller that, when in the free motion sewing mode, activates the feed dog by the feed dog switcher in response to an incoming instruction signal from the first or the second instruction issuer to execute fastening stitching through control of feed dog based on fastening stitching data to longitudinally feed a workpiece cloth.
