Abstract:
1. A carriage apparatus of an ink jet recording apparatus that discharges a photocurable ink and photocures the discharged ink, while relatively being moved with respect to a recording medium in a main scan direction and a sub scan direction, thereby forming a desired image on the recording medium, comprising: a plurality of recording heads for discharging the ink with respect to the recording medium; a recording carriage on which the plurality of recording heads is mounted so as to be divided into a plurality of recording portions in the sub scan direction; a plurality of photocuring units which are disposed on outer sides of the respective recording portions in the main scan direction and the sub scan direction to photocure the ink on the recording medium; and a photocuring carriage on which the plurality of photocuring units is mounted and which is disposed to be separated from the recording carriage, wherein the photocuring carriage includes a first portion and a second portion that are symmetrically situated on, respectively, first and second sides of the recording carriage in the main scanning direction, wherein the photocuring carriage includes a carriage connection portion connecting the first and second portions, the carriage connection portion located on a downstream side of the recording carriage in a sub-scanning direction, wherein, in the photocuring carriage, a plurality of holding portions for holding the respective photocuring units are connected together to form a narrow part, wherein at least one of the photocuring units is arranged between a pair of photocuring units of the plurality of photocuring units in the sub scan direction, the at least one of the photocuring units overlapping in the sub scan direction at least one of the recording heads and both of the pair of photocuring units, wherein at least one of the holding portions is arranged in the sub-scanning direction relative to the recording head, and at least one of the holding portions holds at least one of the photocuring units which is arranged overlapping at least one of the recording heads in the sub-scanning direction.
