Abstract
An ink jet recording apparatus includes an ink jet head, a wiper blade for wiping a nozzle plane of the ink jet head and an ink absorbing member in coupled movement with the wiper blade for absorbing and removing the ink adhered to the wiper blade. The wiper blade wipes the ink jet head over a first overlap width. A second overlap width over which the wiper blade and the ink absorbing member contact is made larger than the first overlap width over which the wiper blade and the ink jet head contact. Therefore, the ink absorbing member comes into full contact with the wiper blade such that the ink is completely absorbed and removed by the ink absorbing member.
Claims20
An ink jet recording apparatus with a frame comprising:
- an ink jet head that ejects ink droplets onto a recording medium, the ink jet head being moved and having a moving plane defined by a nozzle plane while moving;
- a wiping member that wipes the nozzle plane of the ink jet head so as to remove surplus ink on the nozzle plane and recover ink jetting condition of the ink jet head, the wiping member contacting the ink jet head with a first overlap width and contacting an ink absorbing member with a second overlap width longer than the first overlap width, the ink absorbing member absorbing the ink adhered to the wiping member;
- a movable wiper holder that holds the wiper member;
- drive means for moving the wiper holder between a first position where the wiping member linearly projects into the moving plane and a second position where the wiping member linearly retracts out of the moving plane and contacts the ink absorbing member;
- and
- an arm member having the ink absorbing member thereon, the arm member being moved toward a plane of the wiping member, opposite to a recording place of the ink jet head with respect to the recording medium, corresponding to movement of the wiper holder.
