の縫製者にとつてはこの作業は難かしく、また非
効率な作業であるという問題があつた。Problems that the invention aims to solve: Therefore, when performing normal feed → reverse feed → normal feed (normal sewing) at the beginning of sewing, if the speed volume is set to the normal sewing speed (medium speed to high speed). There was a problem that the initial normal feed speed was too fast, making it difficult to know when to press the reverse stitch switch, resulting in too many or too few normal feed stitches. Furthermore, if the normal feed speed is set low from the beginning, the normal feed after reverse stitching will be too slow, and the speed volume must be adjusted each time, resulting in a problem of very low efficiency. Furthermore, at the final edge of the fabric to be sewn, in the case of normal feed → reverse feed → normal feed and stop, it is difficult to know when to turn on the reverse stitch switch at normal speed, so first lower the normal feed speed and then turn on the reverse stitch switch. This poses a problem in that this work is difficult and inefficient for ordinary seamstresses.

送り制御装置８に接続されている。Embodiment FIG. 1 shows a block diagram of a reverse stitch setting device for a sewing machine according to an embodiment of the present invention, in which a speed control circuit 1 controls the rotation speed of a conventional sewing machine motor 2 by controlling a tachometer generator 3 mounted coaxially with the sewing machine motor 2. It reads the output voltage and outputs a drive signal to the sewing machine motor 2 so as to drive the sewing machine motor 2 at a speed corresponding to the set voltage of the speed volume 4. Further, a low speed setting volume 5 is connected to the speed control circuit 1. The speed volume 4 is connected between the power supply Vcc and ground, the slider of the speed volume 4 is connected to the input side of the speed control circuit 1, and this slider is connected to the inverting input terminal of the voltage comparison circuit 6. ing. A voltage set by a resistor 7 connected between the power supply Vcc and ground is input to a non-inverting input terminal of the voltage comparison circuit 6, and an output terminal of the voltage comparison circuit 6 is connected to a feed control device 8.

は送り制御装置８に返し縫い信号を出力しない。 Here, the speed volume 4 is divided into a normal speed setting range A and a reverse stitching range B, and as shown in FIG.
When the slider is set by sliding within the speed setting range A, the sewing machine motor 2 is driven at the set speed as shown in FIG. At this time, the voltage comparison circuit 6 inputs the voltage from the slider of the speed volume 4 and compares it with the voltage of the resistor 7, but since it is higher than the reverse stitch signal, the voltage comparison circuit 6
does not output a reverse stitch signal to the feed control device 8.

The voltage comparison circuit 6 compares the voltage with the voltage of the resistor 7, determines that it is a reverse stitch signal, and outputs the reverse stitch signal to the feed control device 8.
At this time, the sewing machine motor 2 is connected to the sewing machine motor 2 from the speed control circuit 1.
A low speed signal is output.

By sliding the sewing machine motor 2 beyond the click position to the reverse stitching position, the feed control device 8 can shift to reverse stitching operation while the sewing machine motor 2 remains at a low speed. Therefore, in this embodiment, since the speed of the sewing machine motor 2 and the reverse stitching can be changed with one knob 10, there is an advantage that the operation is simple.
