Abstract
PURPOSE:To eliminate the influence of the electric potential of a base paper and obtain a recording picture of high quality without any non-uniformity in recording density by a method wherein a plurality of recording electrode styluses are divided into four groups and the scanning is effected sequentially in the scanning method of a multi-stylus electrostatic recording. CONSTITUTION:The recording electrode styluses 3 are divided into groups each having twelve pieces thereof and are further divided into two groups A, B such as blocks B1, B2,..., while the electrode styluses 3 for respective groups are arranged under mounting on two sets of control electrodes 2. Upon an electric discharge recording under impressing a voltage to the recording electrode 3 and the control electrode 2 concurrently, the recording voltage is impressed only to the A group of the electrode styluses 3 sequentially in accordance with the picture signal thereof in a first scanning, then, it is impressed to the control electrodes (CP1, CP2), (CP5, CP6)... sequentialy to form images of electric charges with respect to the blocks B1, B5, B9. In the second scanning, the scanning is effected only to the B group and the remainders of the A group are scanned in the third scanning while the remainders of the B group are scanned in the fourth scanning. While these scanning are effected, the control electrode 2 is selected to one set for every two sets sequentially, therefore, the influence of the potential of the base paper is eliminated.
