Abstract
A suction recovery mechanism for an ink jet recording apparatus for recording by selectively supporting a different ink jet recording head on a carriage includes a single cap member capable of covering the entire ink discharge port area of each of the different ink jet recording heads selectively supported on the carriage, and a suction mechanism communicating section provided for the cap member in order to perform suction recoveries of each of the ink jet recording heads selectively supported on the carriage. This suction mechanism communicating section is conductively connected with a suction mechanism for sucking ink retained in the cap member. With this arrangement, it becomes possible to widen the range of kinds of images which can be recorded by the apparatus. Also, with the provision of an additional structure to arrange a suction port within a black ink discharge area in the cap member which is conductively connected to a suction pump, it is possible to perform suction recoveries for a color recording head while suppressing color mixture at the time of recoveries.
