ABSTRACT:
An electronic sewing machine is provided with an electronic memory and electronic circuit capable of producing auto-data for controlling the needle lateral amplitude and the fabric feed to thereby form respective stitch patterns of an automatically controlled size, and manual signals acting on the auto-data for manually adjusting the needle lateral amplitude and the fabric feed in response to operation of adjusting dials arranged on a front panel of the machine. The manual signals can be produced separately for adjusting the needle lateral amplitude and the fabric feed independently from each other to thereby stitch a deformed configuration of the stitch pattern, but the machine is so designed that the needle lateral amplitude and the fabric feed are simultaneously adjusted by one and the same manual signal in response to operation of one of the adjusting dials for proportionally enlarging or reducing the automatically controlled size of the stitch pattern with its configuration being unchanged.
