Title: Electrostatic recorder having a fixed head made up of a laminated stack of recording styli

Abstract: An improved recorder for recording substantially simultaneously across the width of a relatively wide sheet of electrosensitive material has a fixed head made up of a laminar stack of recording styli or, as referred to herein, recording pins. Adjacent pins are offset from one another a distance sufficient to allow the passage of a purging fluid therethrough. The purging fluid conveniently may be supplied from a source of low pressure air.
