Abstract: Disclosure relates to an ink storage apparatus with a rotating type ink storage pouch. The ink storage apparatus storing ink to supply the ink to an ink-jet head includes a nozzle ejecting ink includes an ink pouch configured to store ink to supply the stored ink to the ink-jet head, an airtight casing connected to a gas pressure control system, a pouch holding part configured to hold the ink pouch while the ink pouch is inclined at a predetermined angle, and a pouch rotating part configured to rotate the pouch holding part on a predetermined rotating shaft to agitate the ink stored in the ink pouch, wherein the gas pressure control system is configured to control gas pressure of an internal space of the airtight casing, thereby allowing the ink stored in the ink pouch to maintain the meniscus state thereof at the ink-jet head.

Abstract: Proposed is a method of forming an electrode on a surface of an object by using inkjet printing, the method including forming a buffer on an outer edge of an electrode formation position, and forming the electrode by filling electrode ink inside the buffer, wherein the buffer formation is performed by stacking buffer layers formed by inkjet printing of buffer ink, and hydrophilicity of a surface of each of the buffer layers is lower than hydrophilicity of the object surface. According to an electrode forming apparatus, the buffer constituting the outer edge of the electrode is formed high and the electrode ink is filled inside the buffer to form the electrode, thereby enabling the formation of the electrode having an increased sectional area.

Abstract: Proposed is a multi-needle head. The multi-needle head includes at least one adapter mounted with a needle in which liquid is discharged therethrough, and includes a holder in which the adapter is fixed. An O-ring having an outer diameter thereof larger than a width of a body of the adapter is coupled to the body of the adapter, a fixing hole into which the body of the adapter is inserted is formed in the holder, and an O-ring fixing portion having an inner diameter thereof larger than an inner diameter of the fixing hole is formed in the middle of the fixing hole such that the O-ring is positioned at the O-ring fixing portion. A vertical width of the O-ring fixing portion is larger than a vertical width of the O-ring, thereby allowing a height of the adapter that is fixed to the holder to be adjusted.
