摘要： A plurality of photoelectric detector plates are mounted in successive layers on a coupling secured to a sewing machine arm shaft, and have light shields disposed concentrically so as not to be overlapped. Light-emitting means is arranged on one side of the photoelectric detector plates for emitting light toward the latter, and photodetector means is positioned on the other side of the photoelectric detector plates for receiving the light from the light-emitting means. Conditions of the sewing machine can be detected by the manner in which the photodetector means receives the light. The photoelectric detector plates are pressed axially of the coupling and adjustable into given angular positons, respectively, with respect to the coupling.

摘要： One of a plurality of photoelectric detector plates are mounted on a coupling fixed to an arm shaft of a sewing machine, and have predetermined light shields. A light-emitting means is disposed on one side of the photoelectric detector plates for emitting light toward the photoelectric detector plates, and a photodetector means is disposed on the other side of the photoelectric detector plates for receiving the light emitted from the light-emitting means. Conditions of the sewing machine can be detected by the manner in which the photodetector means receives the light.

摘要： An improved lever mechanism interlocked with a pedal in a sewing machine driving device, which lever mechanism includes a rod positioned on one side portion of a lever so as to act on the lever when the latter is pivoted in one direction from a neutral position, and first and second springs of different diameters disposed concentrically with the above rod so as to urge the rod in the direction opposite to the pivoting direction of the lever.

摘要： A sewing machine control box mounted on a non-operative end of a sewing machine frame, and including a partition board which divides the control box into first and second chambers. A transformer which gives off heat in operation is provided in a first chamber, and a printed circuit board which otherwise might be damaged by the heat generated by the transformer is provided in a second chamber. The dividing of the control box into these first and second chambers prevents excessive heat transfer from the transformer to the printed circuit board during operation of the sewing machine.
