Claims

[Scope of Claim for Utility Model Registration] (1) In a drive device that rotates a sewing machine by swinging the starting lever of a clutch motor by depressing a pedal, the starting lever protruding from the side of the clutch motor and the motor. A position detection means for detecting the position of the starting lever and the output of the motor is configured between the machine housing, and a motor drive monitor light consisting of an LED or the like is controlled to turn on or off according to the output of the position detection means. A pedal operating device for a drive motor in a sewing machine, characterized in that: (2) The position detection means is a position sensor fixed to a pedal switch metal fitting that is pivotably pivoted to a mounting metal fastened and fixed to a rod portion of a starting lever extending parallel to the side wall of the motor case, and the pedal A switch abutment that abuts the motor housing is fastened to the tip of the switch metal fitting via a length adjustment means so that it can be adjusted in and out, and the pedal switch metal fitting is elastically biased in the direction in which the switch abutment abuts. 2. A pedal operating device for a drive motor in a sewing machine according to claim 1, wherein the position sensor is configured to face a side edge of said activation lever. (3) A motor-side connecting rod is swingably connected to the end of the starting lever, and a pedal-side connecting rod is connected to the swinging end of the pedal, respectively, and both connecting rods are connected via a connecting fitting so that the length can be adjusted. A pedal operation device for a drive motor in a sewing machine according to claim 1.
