Abstract
A pattern controller performs a needle selection control of a knitting machine with a plurality of piezoelectric needle selectors, each including a plurality of piezoelectric actuators, connected in parallel via an output line. CPU in the pattern controller generates a data signal representing a drive of each of a plurality of piezoelectric actuators in each piezoelectric needle selector for writing into a dual port memory. The dual port memory stores an address signal indicating which of the plurality of piezoelectric needle selectors should be selected and the above data signal. A read circuit operates independently of the CPU and reads an address signal and a drive pattern data from the dual port memory for outputting to an output line in synchronization with a knitting machine operation so as to drive each piezoelectric needle selector.
