[Detailed description of the device]   The idea is to use any type of line, pattern, etc. in sewing with sewing This movement is sewn by tracing the manuscript while tracing the manuscript. The sliding plate, which is rotatably mounted on the upper part, is directly transmitted to the embroidery frame covered with the fabric. Lines and threads of the same shape as long as the thin needle position can be included in the embroidery frame floating range Rotate back and forth and left and right according to the pattern according to the pattern. The embroidery can be sewn and the embroidery work in the frame has been improved so that it looks better overall. The present invention relates to a copy embroidery device that can be attached to a sewing machine.   Among the embroidery devices of this type, the one that can be applied to various sewing machines is the sewing machine bed. A guide rail is fixed to a fixed rail that is fixed horizontally to the rail, and a floating rail that intersects at right angles. A device for performing embroidery stitching by fixing an embroidery frame to the sewing machine (registered patent No. 88 No. 0705), etc., and fix the inner ring to the presser bar of the sewing machine so that the sewing machine needle is at the center. It is fixed and a rotating outer ring is installed around its outer periphery, and a fixed rail is attached to the outer ring and a drawing board is placed on the outer ring. The guide rail is fixed to the fixed rail and the idle rail is installed at right angles. The embroidery frame with the fabric stretched on the edges is fixed so that the sewing machine needle goes around the embroidery frame. With the pointer directly connected to the sewing machine, copy the original image and rotate it to sew the sewing machine and sew it like a thread.
