ABSTRACT:
An input device for an electronically controlled sewing machine is effective for inputting stitch patterns which are partially prohibited from scaling up or scaling down. A control circuit is signalled that points of a stitching pattern are not to be scaled. A check bit added to the coordinate value of prohibited-scaling stitch points flags the scaling prohibition condition.
