Abstract (en)
[origin: US4371881A] A pivotable ink shield is provided for cooperation with the writing head of an ink recording device whereby the shield is movable relative to writing head ink dispensing openings to shield, wipe, and permit flushing of the writing head outlets. The shield element is pivotally connected to a pivotally movable carriage bracket. The carriage bracket is connected with a latch mechanism operated by an electromagnet which enables the carriage bracket to be released under the bias of a resilient force removing the shield between an operating position, permitting ink jet printing on a recording medium, and a blocking position, for plugging the outlet openings of the writing head. The shield element is provided with a resilient wiper element and a closure plate portion such that the outlet openings are first wiped by the wiper element and then closed with the plate as the shield is brought into its blocking position. To clear the outlet openings of dirt, the shield element is separately pivotable relative to the carriage bracket into a flushing position which removes the closure plate portion from the outlet openings, allowing pressure burst cleaning of the writing head outlets.
