A home knitting machine is provided with a reader for reading out patterning instructions on a programmed card, an electronic memory for storing signals read from the card, means enabling an operator to select a needle to knit a particular column of a design unit and to thereby fix the overall position of a design in a width of fabric to be knit, and means for recalling the stored signals from the memory in synchronization with movement of the carriage during knitting and for causing the operations of needle selectors on the carriage in accordance with the recalled signals.

A bobbin thread run-out detector having a light source and means for directing a beam of light toward a set of retro-reflecting reflectors on the bobbin and toward a reference reflecting spot on the loop taker. Bobbin thread wound around the bobbin is interposed between the light source and the retro-reflecting reflectors. When a sufficient quantity of thread has been consumed to expose the indentations to the source of light, the light is reflected to a photodetector. Light from the source is also intermittently reflected onto the photodetector by the reflecting spot on the loop taker during each revolution of the loop taker. An electronic circuit compares the light received by the photodetector from the bobbin with the light received from the reflecting spot on the loop taker. When the quantity of light reflected from the bobbin changes relative to the quantity of light reflected from the loop taker a low bobbin thread alarm is activated to warn the operator of the impending exhaustion of bobbin thread.
