LIQUID DELIVERY HEAD AND RECORDER USING THE SAME

PROBLEM TO BE SOLVED: To provide a liquid delivery head allowing printing at pseudo-high pixel density, and enhancing a through-put without heightening a driving frequency, and a recorder. SOLUTION: This liquid delivery head includes a plurality of liquid delivery holes positioned on straight lines of n lines (n is 4 or more of integer) in parallel along one direction, the liquid delivery holes are arranged along the one direction with an equal interval of distance D (m), not to be overlapped in a direction orthogonal to the one direction, and a distance along the direction orthogonal to the one direction between the adjacent liquid delivery holes with one liquid delivery hole therebetween is integer times of a prescribed length L (m) on an virtual straight line, and a distance along the direction orthogonal to the one direction between the adjacent liquid delivery holes is (integer+1/2) times of the prescribed length L (m) on the virtual straight line, when the liquid delivery holes are projected rigth-angledly to the virtual straight line in parallel to the one direction.
