Abstract
The ink jet recording apparatus and the information processing system using the ink jet recording apparatus as its output device have a cap mechanism that can perform a stable forced suction of ink to recover the performance of the recording head. The cap of this cap mechanism is formed of an elastic member and has a suction surface engageable with the ink discharge surface of the recording head and a back surface engageable with the cap supporting surface of the holding device. Before the holding device is pushed toward the cap by the pressing device, there is a gap formed between the back surface of the cap and the cap supporting surface of the holding device. The distance in the gap between the back surface and the cap supporting surface progressively decreases from the central portion toward the end portions of the back surface, with the end portions of the back surface engaged with the holding device.
