ABSTRACT:
An ultraviolet rays emitter for irradiating ultraviolet rays on an ink of an ultraviolet curing type adhered onto a recording medium includes semiconductor light emitting elements for emitting ultraviolet rays and a support member for mutually supporting these semiconductor light emitting elements in a matrix with optical axes thereof in almost parallel, and the row or column of the semiconductor light emitting elements has a structure in which two kinds of semiconductor light emitting elements having different wavelength ranges or more are arranged in order. Alternatively, an ultraviolet rays emitter has a structure in which a plurality of semiconductor light emitting elements is mutually supported with a support member in a positional relationship in which the optical axes of the respective elements are mutually inclined in such a manner that the irradiation regions of ultraviolet rays emitted from the semiconductor light emitting elements overlap on a recording medium.
