ABSTRACT:
A sheet having marks corresponding to stitch positions along a sewing pattern curve is mounted on a programmer table. A stylus to be positioned at the mark is removably mounted on a movable member which is moved on the table in orthogonal directions by a pair of pulse motors. There are provided memory medium having a memory area for storing pulses applied to the pulse motors between two adjacent marks along the sewing pattern curve corresponding to at least one address, first control means including a ROM writer for transferring the content of the memory medium to a nonvolatile memory means such as ROM or PROM, second control means for reading the content of the memory medium or of the nonvolatile memory means for producing an instruction pulse train for moving the movable member by the pulse motors, and a cutting tool for forming a groove of said pattern curve through a cloth clamping plate mounted on the movable member by the second control means. The first and second control means are constituted by a microcomputer system.
