ABSTRACT:
In a multiple charge electrode device for a liquid jet printer of the type in which a charge electrode unit, a shield plate and a charge sensor plate unit are overlaid, the charge electrode unit or said charge sensor plate unit has a single insulating substrate, a plurality of slots or notches formed along one side of said single insulating substrate, a plurality of charge electrodes or charge sensor plates formed by metalizing the periphery and inner surfaces of each slot or notch, and a plurality of shield electrodes each disposed between the adjacent charge electrodes or charge sensor plates. The shield plate is made of a metal or alloy sheet and provided with a plurality of slots or notches which are aligned with the corresponding slots or notches of the charge electrode and charge sensor plate units and are smaller in dimension than the latter. The shield plate is interposed between the charge electrode and charge sensor plate units.
