摘要： A sewing machine has an automatic control system. This system provides for an automatic sewing mode for sewing according to previously stored sewing data and an ordinary sewing mode for sewing independently of the stored sewing data. When an interruption signal is generated by an interruption signal generating device during sewing process in the automatic sewing mode, the ordinary sewing mode is set and the pressure on the presser foot is released. Therefore, it is capable of smoothly feeding a material when feeding direction of the material is varied.

摘要： A pattern-matching sewing machine that constantly samples photo-intensity data during calculation of a mismatch distance and during adjustment of the feeding mechanism based on the calculated mismatch distance. When the adjustment is finished, a new mismatch-distance calculation is quickly started, not by waiting for sampling new photo-intensity data of a predetermined number, but by using photo-intensity data of the predetermined number including the data thus sampled during the previous calculation and adjustment, and the previously stored data which have been used in the previous calculation.

摘要： A pattern matching sewing machine comprises a sewing means for sewing two superposed sheets of cloth having substantially identical patterns thereon, a feeding means for feeding the two cloth sheets into the sewing means, a detecting means for detecting a mismatch distance between the patterns on the two cloth sheets, and a transport means to transport the two cloth sheets relatively. The pattern displacement amount detected by the pattern mismatch distance amount detecting means may be reduced. A determining means is provided for determining whether pattern matching is possible or not based on the information relating to the mismatch distance obtained by the detecting means.

摘要： A pattern-matching sewing machine having a feed-correcting means for accurately adjusting feed amount using a correction factor with three values which are set according to various sewing conditions such as species of cloths and a speed of a main motor. When the feed amount for pattern matching is calculated based on only a mismatch distance detected by a photo-sensor, the accurate pattern matching is not achieved due to the various sewing conditions. Therefore, the feed-correcting means selects the optimum one of the three values to accurately correct the feed amount for a good pattern matching.

摘要： In a buttonhole sewing machine, a sewing mechanism and a feed bracket are controlled to form a buttonhole defined by settings, such as zigzag stitch length, zigzag pitch, bar-tack length, bar-tack pitch, and cutter space. The buttonhole can be set on the operation panel and changed to various shapes by changing the above settings. In particular, the left and right zigzag stitch widths can be set differently, and the front and rear bar-tack lengths can be also set differently. Thus, the balance of the buttonhole can be finely adjusted.

摘要： A pattern sensor installed in a sewing machine for sensing patterns on two opposing sheets of cloth so that the patterns on the separate cloths are correctly aligned while sewing. The sensor is composed of a sensor head disposed between the two sheets of cloth, a light source, a light receiver, two light conduits including bundles of thin optical fibers, and a reflector which is composed of two prisms provided in the sensor head. The light emitted from the light source is transmitted via separate conduits and respectively enters the prisms. One beam is reflected upward toward the upper cloth, and the other is reflected downward toward the lower cloth for sensing the patterns. The light reflected on each cloth returns to the light receiver via the reverse route to be processed as a pattern signal.
