摘要： PROBLEM TO BE SOLVED: To image and display optional characters, graphics and also dynamic drawings by crests or troughs of a wave on the water surface by utilizing the wave formed on the water surface.
SOLUTION: This device is equipped with multisegment wave generation units for forming a finite water area, and an operation control means having a driving means for generating a wave in the normal direction of each wave generation unit, for outputting a driving signal generating a centralized wave on the coordinate point position corresponding to a desired drawing point position in the finite water area by controlling the driving means. Drawing is performed by the wave front by forming ridged and grooved parts on the water surface by the aggregate of centralized waves generated by the multisegment wave generation units driven by the operation control means. The fluid speed in the normal direction of the wave generation units is controlled so that the centralized wave is generated on the coordinate point position corresponding to the desired drawing point position in the finite water area enclosed by the multisegment wave generation units, and drawing is performed by the wave front by forming ridged and grooved parts on the water surface by the centralized wave aggregate acquired by generating simultaneously the centralized wave on the water surface in the finite water area.
