装置。 a sewing machine motor 6 that rotates the upper shaft of the sewing machine;
In a sewing machine equipped with a sewing machine motor drive device 5 that drives the sewing machine motor based on instructions from a speed setting device, a first contact that is placed in an appropriate position on the sewing machine and is activated by pressing lightly, and a first contact that is activated by further pressing are connected to the sewing machine. a two-stage operation switch 1 consisting of a second contact point that acts simultaneously; and a speed setting device 3 that is operable to set the speed of the sewing machine motor and that instructs the speed according to the set speed. and a discriminator 2 that determines whether the sewing machine is running or stopped and disables the first contact if the sewing machine is stopped;
a low speed control device FF15 that sets the speed of the sewing machine motor to a low speed regardless of the speed setting of the speed setting device; An arithmetic device 4 outputs a signal to the motor drive device 5, and when the two-stage operation switch is strongly pressed while the sewing machine motor is stopped, the first contact point and the second contact point are connected to each other.
The contact closes and starts the sewing machine motor,
When the sewing machine motor is controlled to rotate at the speed instructed by the speed setting device, and the two-stage operation switch is strongly pushed while the sewing machine motor is rotating, the second contact is closed and the sewing machine motor is driven. The device is controlled to instruct the sewing machine to stop, and when the two-stage operation switch is lightly pressed while the sewing machine motor is rotating, and only the first contact is closed, the speed setting device is made inactive and the speed setting device is set to the low speed. A starting/stopping device for a sewing machine motor, characterized in that a control device is provided with a low speed instruction device 17 for controlling the sewing machine motor drive device to give a low speed instruction.
