Abstract
A mechanism for urging an electrostatic recording medium towards a multi-stylus electrode head having needle type charge electrodes and auxiliary electrodes includes a base plate, an elastic member secured to the base plate, and a film-like substance covering the base plate and the elastic member. The width of the elastic member is greater than the width of the electrode head. The film-like substance protects the elastic member from being contaminated and reduces friction thereby increasing the operational life of the mechanism.
