Abstract
A plurality of ink-jet heads are displaced over time on a line scan head loaded with the ink-jet heads, leading to lower printing accuracy. A plurality of uneven portions are formed in parallel with a print-scan direction on the faying surfaces of the ink-jet heads and a head plate loaded with the ink-jet heads, allowing a displacement made over time after positioning to be guided in the print-scan direction. This can suppress a displacement in a direction orthogonal to the print-scan direction, achieving an ink-jet apparatus that can keep high printing accuracy using this solution.
