Abstract
PURPOSE:To uniformize a gap throughout the whole length of a recording electrode, and to facilitate its regulation, by always holding a roller supported with a supporting means in contact to smooth faces provided in both the ends of the electrode, in contact to the circumference of a donor drum. CONSTITUTION:The pressing forces of springs 11 and 11 toward recording electrode 3 are received with support shafts 16 and 16 through both side smooth surfaces 17 and 17, and further, exerted on the circumference of donor drum 1 through rollers 18 and 18 disposed on the ends of shafts 16 and 16. Therefore, the interval between electrode 3 and donor drum 1 is maintained constant independent of eccentricity of drum 1. Besides, roller 18 fixed on shaft 16 is moved by distance X along the circumference of drum 1 by turning adjusting screw 32. This movement X is converted into the change of vertical interval length delta. As a result, the interval is uniformized throughout the whole length of recording electrode, and moreover, its adjustment is made easy.
