Patent ID: 8047645

Claim:
A recording apparatus comprising: a support drum that rotates while supporting a recording medium on a support surface of the support drum; a first guide axis extending in parallel with a rotation axis of the support drum along the support surface; a second guide axis extending in parallel with the rotation axis of the support drum along the support surface; a recording unit carriage that is guided by the first guide axis and moves back and forth along the support surface; an emission unit carriage that is guided by the second guide axis and moves back and forth along the support surface; a recording head for ejecting ultraviolet curing type ink toward a recording medium supported on the support surface, the recording head being mounted on the recording unit carriage and the recording head having a first head unit and a second head unit each of which ejects a different type of ultraviolet curing type ink to each other to a different position to each other along an extending direction of the first guide axis; and an ultraviolet emission unit being mounted on the emission unit carriage and disposed at a down stream side of the recording unit carriage in a rotation direction of the support drum, the ultraviolet emission unit emitting ultraviolet to the ultraviolet curing type ink ejected from the recording head and adhered on the recording medium, the recording apparatus forming an image by ejecting ultraviolet curing type ink on an entire surface of the recording medium supported by the support drum by moving the recording unit carriage along the first guide axis for each time the support drum rotates at least one revolution, the emission unit carriage moves approximately in synchronization with the movement of the recording unit carriage, wherein the ultraviolet emission unit has a first ultraviolet light source and a second ultraviolet light source disposed in the extending direction of the second guide axis and the first ultraviolet light source and the second ultraviolet light source independently generate ultraviolet, and the first ultraviolet light source being disposed to correspond to the first head unit, the second ultraviolet light source being disposed to correspond to the second head unit, the first ultraviolet light source and the second ultraviolet light source generate ultraviolet by an emission condition in which at least one of intensity, wavelength, and emission time of ultraviolet is different to each other.
