Inkjetting device for an inkjet printer

Abstract

An inkjetting device for an inkjet printer includes a plurality of nozzle plates arranged in a parallel line, and a pair of magnets installed on respective upper and lower portions of the nozzle plates. Each nozzle plate includes a pair of parallel levers, which are connected to a bridge at one end portion and separated from each other at the other end portion, and a nozzle orifice to jet ink is formed on a front face of the bridge. Ink is stored in ink chambers respectively formed between the levers of the pairs of parallel levers. By applying an electric current to each lever in the magnetic field formed by the pair of permanent magnets, a Lorentz force affects each lever to move closer to the other one of the pair of parallel levers. Accordingly, the ink is jetted onto printing paper to execute a printing operation.
