Abstract
An ink jet recording apparatus includes a cap capable of moving in approaching and receding directions against and away from a discharge port surface of a recording unit for covering the discharge port surface, a wiper sliding while contacting with the discharge port surface to wipe the discharge port surface to clean it, a wiper driving gear for transferring drive to the wiper, a cam and gear member equipped with a cam portion for controlling the movement of the cap and a gear portion for transferring drive to the wiper driving gear, in which the cam and gear member is configured so that the gear portion engages with the wiper driving gear after the cap has moved to a position where the cap does not interfere with the wiper. By such a configuration, both of the capping operation and wiping operation can be controlled with the single cam and gear member, which makes it possible to miniaturize a recovery mechanism portion for maintaining and recovering the ink discharging performance of the recording unit. Thereby, the recording apparatus body can be miniaturized.
