Stitch pattern sewing machine

Abstract

An automatic sewing machine wherein a plurality blocks of unit pattern information including many position data which are respectively corresponded to each of various unit stitch patterns such as letters, symbols, etc. are stored in memory means. In this machine a first manual means for selecting an individual unit pattern information from the plurality blocks of unit pattern information stored in the memory means in a desired order and a second manual means capable of determining at will an individual size, an individual inter-distance, and arrangement direction of the selected unit stitch patterns when they are formed on a workpiece are disposed in an operable manner by an operator. A newly combined stitch pattern consisting of a plurality blocks of unit pattern information selectively designated by the first manual means is modified owing to an operation of the second manual means, and each position data of the modified combination pattern information is read out in response to a synchronizing signal from the stitch forming mechanism. The workpiece is changed its position in relation to the needle according to the read out position data. In this way a combination stitch pattern is formed on the workpiece in a determined size, distance, and arrangement direction by the sewing operator.
