Abstract

PURPOSE:To easily obtain the fixed speed for the sewing machine using a microcomputer by a method wherein a speed setting structure is constituted by a varying speed setting element which corresponds to the movement of the sewing machine pedal and a prescribed speed setting element containing a pulse generator. CONSTITUTION:The output of the varying speed setting element 7, corresponding to the amount of depression of the sewing machine pedal, is inputted to the microcomputer 8, a motor 3 and the sewing machine 5 are driven by controlling a clutch 11 and a brake 12 using drivers 9 and 10, the number of revolution of the above is detected by a frequency generator 13, the detected result is inputted to the microcomputer 8, and the sewing machine is operated at varying speeds. On the other hand, a low speed setting element 15 containing a pulse generator 18, an intermediate speed setting element 16 and a maximum speed setting element 17 are provided, their output is inputted to the microcomputer, and an arithmetic operation is performed, thereby enabling to operate the sewing machine at respective fixed speeds. Accordingly, the digital control system using the microcomputer 8 can be brought into a very simple structure, and the reliability of the titled device can also be improved.
