Abstract
A wiping apparatus for a recording head of an ink jet recording apparatus, which has a recording head including an ink ejection portion, includes a wiping member, and a rotation device for rotating the recording head and/or the wiping member so that the wiping member slides on the ink ejection portion. The apparatus prevents the splash of ink caused when the wiping member leaves the ink ejection portion by using one of the following techniques: First, a wiping speed is decreased at the end of wiping; second, an angle between the wiping member and the ink ejection portion is declined as the wiping proceeds; third, the first and second techniques are combined; and fourth, an approach amount of the wiping member to the ink ejection portion is reduced at least just before the wiping member leaves the ink ejection portion. Using one of these technique enables the wiping member to leave softly the ink ejection portion by weakening the restoring force of the wiping member, thereby preventing ink from splashing into the surroundings during the wiping operation.
