手段１１及びミシンモータ７を制御する制御手段
２２と、よりなるミシンの針停止位置制御装置。[Claims for Utility Model Registration] A needle 3 that moves up and down as the sewing machine main shaft 4 rotates; a sewing machine motor 7 that can rotate in forward and reverse directions and that imparts rotation to the sewing machine main shaft 4; and a sewing machine motor 7 that rotates the needle 3 in a predetermined position. a brake means 11 that applies a braking force to the motion system between the sewing machine motor 7 and the needle 3 so as to stop the needle 3 at a stop; and a first detection means 6 that outputs a detection signal when the needle 3 reaches the predetermined position. and a second detection means 6 that outputs a detection signal when the needle 3 overruns the predetermined position, and releasing the braking force by the brake means 11 based on the signal from the second detection means 6. At the same time, a control means for controlling the brake means 11 and the sewing machine motor 7 so as to reverse the sewing machine motor 7 to cause the needle 3 to move backward, and to stop the sewing machine motor 7 based on the signal from the first detector 6. 22, and a needle stop position control device for a sewing machine.
