Claims

[Scope of Claim for Utility Model Registration] Start button switch 8, SS, which is provided on the main body and generates an activation signal when pressed while the sewing machine is stopped, and generates an inactivation signal when pressed while the sewing machine is running.
W, CT, and operation button switch means 11, B provided in the main body close to the start button switch means and connected to the cloth feeding mechanism so as to generate a reverse stitching signal when pressed and to reverse the cloth feeding direction during the pressing operation.
SW, and control means G2, G11 for driving the sewing machine in response to generation of an activation signal or reverse stitching signal and bringing the sewing machine into a stopped state in connection with generation of a non-operation signal.
, CT, the sewing machine is driven by pressing an operation button switch means to form reverse direction stitches, and by releasing the operation, forward direction stitches are continuously formed.
