Abstract
Abstract A home knitting machine is provided with a read only semiconductor memory device which has a plurality of patterning instructions, electric signal generator means for generating carriage position indication signal in response to movement of the carriage during knitting, an electronic control system for reading out instructions from the memory device in response to the carriage position indication signal, needle selectors energized pursuant to read out instructions from the memory device to provide design patterns in a fabric, and an input unit for determining reading out sequence of the electronic control system so as to select a design pattern by manual operation of a user.

Claims Analysis
Total Claims: 8
Claim 1
Independent Claim
162 words
A home knitting machine for producing programmed designs comprising: a needle bed supporting a plurality of needles in side by side relation; a carriage mounted on the bed for movement traversing the needles; detection means for generating carriage position signals in response to traversing movement of the carriage; needle selection means for selecting needles to knit a design pattern in response to design pattern data; an electronic control system including a semiconductor read only memory device having two separate sections, one for storing basic design pattern unit data and the other for storing specific design fabrication programs said two separate sections functioning together to yield specific combination design patterns in response to a series of design fabrication instructions, said electronic control system further comprising a central control unit for supplying out design pattern data in accordance with appointed programs in response to the carriage position signal; and key switches for appointing codes corresponding to the specific programs to the electronic control system.
