Abstract
To aid in the proper placement of patterns to be sewn on work fabric, a sewing machine includes a pattern projection system for forming pattern images on the fabric. The pattern images are of the same size and orientation as the pattern sewn by the machine. The image projection system includes a light source and a light transmission imaging element for forming images on the fabric. The imaging element can be liquid crystal. The image forming system displays a marker to indicate that portions of the pattern to be sewn are outside a predetermined image area. A memory is provided to store pattern completion data, so that after an interruption in the sewing of a pattern, the unfinished part of the pattern can be imaged on the fabric and the machine can complete the pattern.
