DROP GENERATING APPARATUS

PROBLEM TO BE SOLVED: To provide a drop generating apparatus such as a drop jet device. SOLUTION: In this drop generating apparatus, first and second linear arrays NA and NB, which are arranged side by side along a lateral axis so that a plurality of columnar arrays, composed of a plurality of nozzles 47, can be almost parallel to one another and can be each inclined with respect to the lateral axis, are arranged adjacently to one another along a longitudinal axis so that the respective columnar arrays can establish such a positional relationship as to be displaced by a predetermined distance from one another along the longitudinal axis. In the drop generating apparatus, a plurality of linear subcolumns, which are alternately engaged with one another, are formed so that the adjacent nozzles belonging to the same columnar array can form an odd-even nozzle pair in each columnar array; and the respective nozzles 47 are arranged so that X-axis-direction positions of the nozzles constituting the odd-even nozzle pair can be different from one another.
