Abstract

Disclosed is an inkjet printer including an inkjet head containing electrically conductive ink and having a nozzle for spraying the ink and a mask positioned on a side of the inkjet head, the mask having a number of slits formed so that the electrically conductive ink passes through the slits and an electromagnetic field is established. The electromagnetic field is used to control the direction of movement of sprayed ink for uniform ink spraying.

Claims (5)

1. An inkjet printer comprising:

an inkjet head containing electrically conductive ink and having a nozzle for spraying the ink and

a mask positioned on a side of the inkjet head, the mask having a number of slits formed so that the electrically conductive ink passes through the slits and an electromagnetic field is established

wherein the mask has a number of electric wires positioned on a highly-elastic thin metallic layer so that opposite polarities alternate with each other while being adjacent to each other and magnets laminated on the electric wires with an insulation layer interposed between each layer.

2. The inkjet printer as claimed in claim 1 , wherein the magnets establish a magnetic field in a predetermined direction and a current flows through the electric wires in a predetermined direction so that electromagnetic force is created by the magnetic field and the current towards a center of the slits.
