    摘要： During stitching a pattern, there is often issued a designation to change the pattern under forming to the other. In such a case total load on a fabric feed control motor and a needle amplitude control motor is temporarily increased. A microcomputer which controls driving of these motors, discriminates the new designation and rotating phase of the sewing machine and drives the fabric feed control motor by means of specific data by mean value of the maximum and the minimum fabric feed control data, instead of the fabric feed control data which is first read out next to said designation. The control amount brought about by difference between said specific data and the fabric feed control data read out prior to said designation which controls as the final fabric feed before said designation, is caused to prevent the maximum available to the sewing machine so that the total load applied to the two motors are reduced when the maximum possible control is given to the needle amplitude control motor in succession to the load on the fabric feed control motor.

    摘要： A method of forming a stitch pattern is disclosed in which at least two closely spaced or coincident end stitches are present. The overall pattern is divided into overlapping block sections. In one block, a first group of stitches is formed followed by a second group of stitches being formed in an adjacent block. The number of stitches between closely spaced or coincident stitches that results is reduced. Therefore the accumulated error of fabric feeding pitches and the distance between the two end stitches is reduced resulting in a more precisely constructed overall pattern.

    摘要： Intercharacter data for use in an electronic sewing machine is prepared by the steps of constituting each intercharacter control data with a first stitch control data group for determining relative position between a fabric and a character, a second stitch control data group utilized to form the character, and a third stitch control data group for determining a spacing between adjacent two characters; drawing a top segment .alpha. and a bottom segment .beta. respectively passing through top and bottom portions of the characters in parallel with the fabric feeding direction; and drawing a front segment X and a rear segment Y respectively passing through mostly projecting portions of the character on the front and rear sides thereof with respect to the fabric feeding direction in perpendicularly to the segments .alpha. and .beta.. Then the needle position of a first stitch point effected by the first stitch control data group comes to a position near the segment X and the area (Sh') of a front blank portion bounded by a segment X.sub.0 ' passing through the first stitch point in parallel with the segment X, the contour of a character to be stitched next, and the segments .alpha. and .beta. is substantially the same between any two adjacent characters. Moreover, the area (St') of a rear blank portion bounded by a segment Y.sub.0 ' passing through a last stitch point provided by the third stitch control data group in parallel with the segment Y, the contour of a previously stitched character and the segments .alpha. and .beta. are also substantially the same between any two adjacent characters.

    摘要： In a stitch control process of the sewing machine which employs a microcomputer with an electronic memory storing stitch control signals and a needle position control motor and a fabric feed control motor, the microcomputer controls the needle position and the fabric feed control motors at certain rotation phases of the sewing machine. The microcomputer temporarily holds, during the operation of the sewing machine, the needle and feed control data and the feed control amount based on the feed control data which are read out in each phase and calculates the addition of the feed control amount and the needle control amount based on the needle control data which is read out at the following phase. If the calculating result is more than a predetermined value, the microcomputer employs the needle and feed control data read out at the preceding phase instead of the needle and feed control data read out at the following phase to control the feed and needle control motors with a total value of the needle and feed control amounts which is less than the predetermined value.
