Abstract
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.
