Abstract
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.
