Abstract
In a matrix circuit for an electrostatic recording device comprising a sequence of control electrodes, cross-point elements to be selected in pairs to cyclically drive the control electrodes, with two consecutive ones in the sequence driven at each instant, are arranged always along a common matrix conductor. The cross-point elements for the sequential control electrodes may be arranged in a reciprocating or a staggering manner along each pair of the matrix conductors, in a spiral manner passing through all matrix points, or in a somewhat irregular manner. The cross-point elements may be selected, with one of the pair for driving the trailing one of the two consecutive control electrodes again selected at the next succeeding instant together with another cross-point element for the control electrode next following in the sequence the trailing control electrode, by a logic circuit driven by a counter for counting clock pulses defining the instants.
