Patent ID: 7661807

Claim:
An ultraviolet rays emitter, emitting ultraviolet rays onto an ink of an ultraviolet curing type, which is ejected onto a recording medium by recording head, comprising: a support member; and a plurality of light emitting elements attached to the support member and adapted to emit ultraviolet rays, wherein the light emitting elements are arranged in rows and columns with optical axes thereof aligned in almost parallel to one another so that irradiation regions of the ultraviolet rays emitted by the light emitting elements are gathered in a state being almost adjacent to one another so as to form a large irradiation region, and at least two of the emitting elements emitting the ultraviolet rays having different wavelength ranges are arranged in one of the rows, and at least two of the emitting elements emitting the ultraviolet rays having different wavelength ranges are arranged in one of the columns.
