Abstract: INERTIAL DEFLECTION FIELD TILTING FOR BI-DIRECTIONAL PRINTING IN INK JET PRINTERS In a continuous type ink jet printer having a conventional charging electrode for charging ink drops in accordance with a signal to be recorded on a record receiving media, a pair of deflection electrodes is mounted in a rocker which pivots on a holder mounted on the carrier. As the carrier is accelerated from the stop condition to print speed, the acceleration of the carrier effects rotation of the rocker about the pivot and thus automatic tilt of the deflection electrodes backward from the direction of carrier movement thereby tilting or inclining the electric field formed between the electrodes to compensate for carrier movement. In the preferred form, a simple magnetic type latch is applied to retain the rocker in one position for printing in a first direction, and to enable quick release and reversal, under inertial control, when the carrier moves in the opposite direction.
