Claims

[Scope of utility model registration request]

In an electronic sewing machine in which a reversible motor controls a feed adjuster that controls the feed movement of a feed device, a drive member rotatably driven by a reversible motor controlled by a pattern data signal, an adjustment plate, and a feed adjuster are supported, respectively. Pivotally fitted onto the shaft, the protrusion provided on the adjustment plate and the engagement surface of the arm provided on the drive member press against each other by a first spring to connect the drive member and the adjustment plate; , the adjusting plate is provided with a long hole, an eccentric cam rotatably attached to the feed adjuster is inserted into the long hole, and a second spring causes the cam surface of the eccentric cam to align with one end of the long hole. The adjusting plate and the feed adjuster are connected by pressure contact so that the mounting angle can be adjusted by rotation of the eccentric cam, and a detection protrusion is formed on the drive member so that the feed adjuster is in the neutral position. A feed control device for an electronic sewing machine, characterized in that it is provided with a non-contact type detection device that detects the detection protrusion when the detection protrusion is in the position.
