Claims

[Scope of claim for utility model registration] Memory that stores information on the needle swing amount and the forward/reverse direction and amount of cloth feed corresponding to the first and second stitches and parallel portions of buttonhole sewing by electrical or mechanical means. a needle swing means associated with the needle bar so as to swing the needle bar in a direction horizontal to the cloth feeding direction in accordance with the information on the storage body; and a cloth feeding direction corresponding to the information on the storage body. A cloth feeding means that applies a feed motion to the feed dog depending on the amount, a motor connected to the main shaft, a drive circuit that can drive and stop the motor, and a start signal and motor that are connected to the drive circuit and start the motor by manual operation. An operating body capable of generating one of the stop signals to stop the machine, and a direction parallel to the cloth feeding direction on the underside of the jaw of the machine frame.
A set lever that is movably supported and can be manually set to one specific position in the movement direction corresponding to the first needle of the bar tacking stitch, and a set lever that is driven by a feed dog and can be moved along the cloth feed direction. The presser foot frame is supported at the lower end of the presser foot bar and can be held on the set lever so as to move the set lever. After that, the cloth feed direction is changed and the motor is automatically stopped in relation to the second predetermined position of the set lever, which is behind the first predetermined position in the forward cloth feed direction. In the sewing machine, the detection means is arranged in relation to the set lever and generates a set signal in relation to a specific position of the set lever, and generates a stop signal in relation to a second predetermined position of the set lever; Alternatively, a set includes a notification means that generates a sound to notify the user, and a regulation circuit that regulates the drive circuit so that when the motor is stopped, the motor can be started in an active state and cannot be started in an inactive state. A buttonhole sewing control device for a sewing machine, comprising: a control circuit that activates a regulation circuit and activates a notification means from generation of a signal until generation of the next stop signal.
