摘要： An electronically controlled sewing machine includes an electronic memory storing a plurality of stitch control data for respective stitch patterns, including a darning pattern composed of a number of vertical straight stitch lines sequentially produced in forward and reverse fabric feeding directions. A number of signals which are generated each time a fabric penetrating needle ascends above the fabric between the first stitch and the last stitch of each vertical straight stitch line of the darning pattern, are counted up by a counter to produce a corresponding value signal. The latter signal is compared with another value signal latched in a latch circuit in response to operation of a turning point designating switch adapted to designate a number of stitches for each vertical straight stitch line of the darning pattern. When the value signals coincide with each other, the count-up operation of the counter is reset for producing a subsequent vertical straight stitch line.

摘要： A plurality of different stitch patterns are stored in a first static memory. A second static memory memorizes a combination of these different patterns in a predetermined sequence. A third static memory stores basic needle position signals each specific to the patterns stored in the first memory. Calculating means utilize signals derived from the second memory and the third memory to determine values for adjusting the swinging amplitude of the sewing needle with a common variation rate and for setting a common basic needle position.

摘要： A control circuit is disclosed for operating a pulse motor which contains a first winding and a second winding. A first bridge can connect the first winding to a power source in two directions and can also disconnect the first winding therefrom. Likewise, a second bridge can so connect and disconnect the second winding from the power source. A sequencer operates the bridges so that such connection and disconnection takes place according to a predetermined sequence, in order to allow the motor to be rotated in discrete steps. A comparator stage compares current flowing through the first and second windings with an adjustable voltage reference, and regulates the bridges so as to regulate such current in accordance with a value to which the adjustable voltage reference has been adjusted. A means adjusts the adjustable voltage reference in accordance with the predetermined sequence. The control circuit reduces power consumption by the pulse motor and thereby allows a smaller torque pulse motor and a smaller power source to be utilized.

摘要： A sewing machine control circuit is disclosed in which acceleration or deceleration of the machine is effected by the operator in such a way as to gradually increase or decrease motor speed during periods of operator intervention and to maintain whatever speed exists at the time operator intervention ceases. Improved circuitry is utilized to perform these functions.
