ABSTRACT:
An optical buttonhole switching arrangement in which the movement of reflective means carried on a moveable buttonhole foot are sensed as the foot is moved by the fabric feeding movement of a feed dog against the garment being sewn. The foot includes adjustable optical targets whose movement may be sensed by a photosensor carried on the sewing head. The spacing of the optical targets may be manually adjusted to accommodate buttons of different sizes. The photosensor is connected to an electronic circuit whose output may be used to control the retrieval of buttonhole stitching information from an electronic memory.
