ABSTRACT:
An input device for sewing machines is disclosed which reads from a memory circuit an original sewing pattern which has been already stored, enlarging or reducing the coordinate data of the original sewing pattern in a desired scale, and prepare the coordinate data of sewing points between the flexing points thus obtained by enlargement or reduction in accordance with a desired stitch length data or stitch number data. The input device is adapted to convert the coordinate data of the original sewing pattern to the coordinate data calculated with the central point of a crank member of a work holder with the crank member as the origin and enlarge or reduce the coordinate data of the flexing points other than the starting point and the ending point of sewing in a desired scale, when the original sewing pattern is for a work holder with a crank member.
