Abstract
An electrode array is disclosed for a print head of an electrooptical facsimile recording device for recording spots line by line. The recording spots are exposed on a recording medium through light gates (35). These light gates (35) are arranged in rows and are defined by high field strength edge portions (switching areas) of spot electrodes (22, 22') and main electrodes (23, 24, 25, 26). Each spot electrode (22, 22') is associated with n light gates (35, 19), each spot-electrode row (27, 28) being associated with n main electrodes, so that n(N-n) light gates are formed by N electrodes. The electrode array in designed so that each spot-electrode row (27, 28) is between at least wo elongated main electrodes; each spot electrode 22 has n switching areas (20, 21) which are located adjacent n respective main electrodes.
