信号しか出力されない。On the other hand, if it is determined that the sense line 1 is at a high level, it is determined that the cloth edge detector 23 is attached, and then the process proceeds to step 120, where it is determined whether or not the sense line 3 is at a high level. At this time, if the sense line 3 is not at a high level, it is determined that the operating switch 23c of the detection unit 23b is not turned on, and this processing routine is exited and the process proceeds to another process, while the sense line 3 is at a high level. If it is determined that the operation switch 23c of the detection unit 23b is in the on state, the process proceeds to step 130, where the output from the 1 cloth edge detector 23 is manually transmitted through the line 0 in the operation panel 30. capture the detected signal. The fabric edge detector 23 emits light from the light emitting part of the light emitting/receiving part 23a toward the throat plate 19 directly below, and the light receiver receives the reflected light and generates a detection signal. In a state in which the stitches cover the entire throat plate, that is, in a state in which the stitches do not reach near the edge of the fabric, the light receiver cannot receive the reflected light and only a low-level detection signal is output.

行する。Therefore, in the next step 140, it is determined whether or not the cloth edge is detected depending on whether or not this detection signal is at a high level.
If the detection signal is low and the edge of the work cloth 20 has not reached the vicinity of the sewing position, it is determined that the edge of the fabric has not been detected, and the process exits from step 140 and moves on to other processes. .

At this time, when step 140 is executed, it is determined that a cloth edge has been detected, and the process proceeds to step 150.
ステップ１５０では、針数のカウントを開始し、針位置
検出器２７から送られる計上位置又は針下位置検出信号
を針１６の上下動毎に取り込み、計数をカウントする。In step 150, counting of the number of stitches is started, and the counted position or needle down position detection signal sent from the needle position detector 27 is received every time the needle 16 moves up and down, and the count is counted.

次にステップ１７０に進み、ミシンモータ１３を減速停
止させるための制御信号をモータ制御回路４４に出力し
、ミシンモータ１３を減速停止させる。Then, proceeding to step 160, it is determined whether the number of stitches has reached the set number of stitches set in advance on the operation panel,
When the sewing progresses and the stitch count reaches the set number of stitches,
Next, the process proceeds to step 170, where a control signal for decelerating and stopping the sewing machine motor 13 is output to the motor control circuit 44, thereby causing the sewing machine motor 13 to decelerate and stop.

Sewing can be automatically stopped at any position of the fabric edge, but if the fabric edge detector 23 is not installed or the detection unit activation switch 23c is not turned on, the steps from step 130 onwards will be stopped automatically. This is not executed, and automatic stop control based on cloth edge detection as described above is not performed.

Therefore, the control device automatically connects (installs) the detector.
Even if sewing machines are manufactured with various specifications depending on the presence or absence of a detector, the basic control circuit can be used in common, and the effectiveness of mass production of sewing machines can be improved. can be raised. In addition, there is no need to switch switches in the control circuit depending on whether the detector is connected or not, and the device can be easily used.
