PROBLEM TO BE SOLVED: To obtain a coater for print sheet in which the coating liquid is prevented from scattering to other than the surface of a print sheet and different coating substances can be used selectively. SOLUTION: The coater for print sheet for coating the surface of a printed sheet-like medium with a colorless transparent liquid coating substance comprises a coater body including an on-demand coating head 6 for jetting only the coating liquid from a plurality of jet openings without entraining a compressed gas flow by converting the energy of an electric signal to apply a physical acting force directly to the coating liquid, and means for moving the on-demand coating head 6 and a printed sheet-like medium relatively while facing each other, and a coating liquid unit integrating the on-demand coating head 6, a coating liquid container and a flexible piping tube coupling them. The coating liquid unit can be mounted/demounted on/from the coater body integrally. |
