PROBLEM TO BE SOLVED: To prevent junction breakage by removing junction from the cell, and deterioration of a laser beam wavefront by dividing the cell into blocks, and pressing these butting parts from outside. SOLUTION: A cell 10 is constituted by placing a push block 12 opposite a passage block 11, and the push block 12 is pressed with an elastic body 20 and a pressure board 21 so that the block may not be broken by the pressure of the coloring matter flowing through the passage to cause the coloring matter to flow out. Hereby, the cell 10 can be constituted without a junction, and besides the transformation of the block by the difference between the inner pressure and the outer pressure is small, and it little gives distortion to the laser beam wavefront. |
