摘要

Sewing machine comprises a sensor (17) for determining the position of the presser foot (22) relative to the base plate (4) in the foot's lowered position, a sensor (34) for determining the thickness of the material to be sewn, and a control unit (20) for controlling the sewing machine in response to signals from the position sensor and thickness sensor.
