Patent ID: 7997716

Claim:
A UV curable ink-jet recording apparatus comprising: a recording medium transporting unit for transporting a recording medium; an ink jet head which, on the basis of an image signal, ejects an ink that is curable by UV irradiation, toward the recording medium transported by said recording medium transporting unit; and a UV irradiating unit for curing the ink which is ejected onto the recording medium by said ink jet head, wherein said apparatus comprises a light capturing portion between said UV irradiating unit and said ink-jet head, at least a part of said light capturing portion as seen in a longitudinal section taken vertically along a direction of transporting the recording medium has an opened wedge shape having no base side and comprising: a side vertical to the recording medium; and an oblique side which is in contact with a top of the vertical side, and which extends obliquely downward, the vertical side is located on the side of said ink-jet head, and the oblique side downward extends from the top toward said UV irradiating unit; and a light shielding side which is in contact with a lower end of the oblique side, wherein when a distance between both lower ends of an opening of said wedge-shaped light capturing portion in the direction of transporting the recording medium is a, a gap between the recording medium and the lower ends of said light capturing portion is b, and tan θ=2b/a, an opening angle of the wedge shape is α≦θ/2, and an angle β formed by the oblique side of the wedge shape and a light shielding side which shields said UV irradiating unit is 90°<β≦180°.
