Title:
PATTERN DISPLAY APPARATUS OF SEWING MACHINE
Document Type and Number:
Japanese Patent JPS59177093
Kind Code:
A
Abstract:
An electronic sewing machine with a dot matrix display for representing the image of a selected pattern to be stitched, having a first memory which stores stitch control data which may be sequentially read out in dependence upon a selected pattern per rotation of the sewing machine and transmitted to a driving part of a stitch forming mechanism; prior to initiation of the driving part, a calculator receives the read out stitch control data to make calculations for linearly interpolating between the adjacent stitches, thus to repeatedly renew the stitch control data into display data; a second memory stores the display condition data for controlling the cycle of pattern unit to be displayed; a counter counts up the cycles of the selected pattern in reference to the renewed stitch control data. Thus when the display calculations are finished through out the pattern cycles, the sewing operation is made possible, and the calculated display data are temporarily stored in a third memory to drive the dot matrix display of the sewing machine.
