Abstract
An electronically controlled sewing machine includes an electronic memory storing a plurality of stitch control data for respective stitch patterns, including a darning pattern composed of a number of vertical straight stitch lines sequentially produced in forward and reverse fabric feeding directions. A number of signals which are generated each time a fabric penetrating needle ascends above the fabric between the first stitch and the last stitch of each vertical straight stitch line of the darning pattern, are counted up by a counter to produce a corresponding value signal. The latter signal is compared with another value signal latched in a latch circuit in response to operation of a turning point designating switch adapted to designate a number of stitches for each vertical straight stitch line of the darning pattern. When the value signals coincide with each other, the count-up operation of the counter is reset for producing a subsequent vertical straight stitch line.
