IMPROVED HOUSEHOLD TYPE SEWING MACHINE HAVING MICROPROCESSOR CONTROL Abstract of the Disclosure A household type sewing machine having a bed, a standard rising from said bed, a horizontal arm overhanging said bed, said arm ending with a head, a needle bar means disposed in said head for enabling transverse oscillation thereof relative to the direction of fabric feed in said sewing machine, feed means for adjusting the length and direction of said fabric feed, actuator means for adjusting the transverse position of said needle bar means and the positional displacement of said feed means in response to control signals provided thereto and first static memory means for retrievable storing a first plurality of different predetermined stitch patterns each having associated retriev- ably stored bight and feed data corresponding to predetermined positional coordinates of said needle bar and feed means for defining associated stitch position coordinates for the stitches comprising said stitch patterns; characterized by a microcomputer integrated circuit means operatively connected to said static memory means and to said actuator means for selectively pro- cessing said stored stitch pattern data from said static memory means and providing output control signals to said actuator means based on said selectively processed stitch pattern data for controllably adjusting at least the trans- verse position of said needle bar means, said microcomputer processing means comprising means capable of selectively controllably functionally operating on said stored stitch pattern data in response to input control signals for controll- ably redefining said stored stitch pattern data for selectively creating output control signals for said actuator means different from the output control signals corresponding to any one of said stored stitch patterns whereby at least the transverse position of said needle bar means may be selectively varied to redefine a stitch pattern arrangement different from any one of said stored stitch patterns; and keyboard means operatively connected to said microcomputer means for providing said input control signals to said microcomputer processing means for initiating the selection of at least one stored stitch pattern and the functional operation to be performed on said associated selected stored stitch pattern data for controllably adjusting at least the transverse position of said needle bar means for selectively providing a final stitch pattern arrangement from said plurality of stored stitch patterns, whereby said sewing machine is capable of providing stitch pattern arrangements corresponding to said stored stitch patterns per se as well as to selectably creatable variations thereof.
