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 swinging means associated with the needle bar so as to swing the needle bar in a direction horizontally intersecting the direction of cloth feeding in accordance with the information on the memory; and a direction of cloth feeding corresponding to the information on the memory. A cloth feeding means that gives a feed motion to the feed dog depending on the amount and quantity, a motor connected to the main shaft, a drive circuit that can drive and stop the motor, and a cloth feeding mechanism that moves in a direction parallel to the cloth feeding direction on the underside of the jaw of the machine frame. a set lever that can be manually operated to be set at one specific position in the direction of movement corresponding to the first needle of the bar tacking stitch, and a presser bar 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 and can be held on the set lever so as to move the set lever. In the sewing machine, the sewing machine is configured to reverse the direction of cloth feeding after the feed is completed, and a detection means is arranged in relation to the set lever and generates a detection signal when the set lever is not set at a specific position; A buttonhole sewing control device for a sewing machine, comprising: a notification means for generating a sound to notify the user; and a control circuit for operating the notification means in connection with the generation of a detection signal.
