MOTOR-DRIVEN TYPE SEWING MACHINE

摘要

A motor-driven type sewing machine is provided to closely install a driving motor to a rear wall of a frame of the sewing machine, thereby simplifying the entire structure of the sewing machine. A sewing machine frame includes a sewing machine bed member(1A) and a sewing machine arm member(1B). A cylinder bed member(2) is extended toward the reverse direction of the sewing advance direction from the front lower portion of the sewing machine bed member. A detachable rear cover(3) is installed at the rear of the sewing machine bed member and opens and closes an opening when the maintenance and checking of the internal mechanism are performed. A main shaft(4) is protruded toward the outside of the sewing machine bed member. An electronic motor(5) is located at the neighborhood of the rear cover. An output shaft of the electronic motor is located in parallel to the main shaft. The electronic motor is supported to the inside of a motor attaching member(11) through plural bolts(13). The motor attaching member is detachably installed to the outside of the sewing machine bed member through plural first screw members(12).
