ABSTRACT:
An electric discharge printing device has the stylus formed as a conductive lamina with the stylus tip formed as the corner at which two edges of the lamina of the stylus intersect. The lamina is electrically energized to exert the appropriate electric discharge printing action on a copy sheet, such as a duplicating stencil to be cut electrically. The plane of the lamina is perpendicular to the copy sheet but parallel to the direction of relative motion between the stylus tip and the sheet, in use of the device.
