Claims

[Scope of Claim for Utility Model Registration] (1) In an inkjet printer that supplies ink to a head mounted on a carriage via an ink tube from an ink cartridge removably installed in the printer body, An inkjet printer characterized in that a cleaning member is attached that comes into contact with the nozzle surface of the head when the carriage moves. (2) In claim 1, a retraction mechanism for the cleaning member is provided between the ink cartridge and the cleaning member so that the cleaning member does not apply an overload force to the nozzle surface of the head. An inkjet printer characterized by: (3) In claim 1 or 2, the cleaning member is a cleaning roller that rotates due to frictional force with the nozzle surface of the head when the carriage moves, and the rotational resistance of the cleaning roller is reduced when the carriage moves forward and backward. An inkjet printer that is characterized by a change in color. (4) In claim 3, the cleaning roller further comprises a pawl gear provided on the rotating shaft of the cleaning roller and having a tooth surface having a different angle during forward rotation and reverse rotation, and a pawl member that engages with the pawl gear, An inkjet printer characterized in that the rotational resistance of the cleaning roller changes when the carriage moves forward and back. (5) In claim 3, the surface of the cleaning roller is provided with a chevron-shaped portion around the surface, and each side surface of the chevron-shaped portion has a different shape, so that the cleaning roller has a different shape when the carriage moves forward and backward. An inkjet printer characterized in that the rotational resistance of the cleaning roller is variable. (6) In claim 3, the ink cartridge is provided with a resistance member that comes into contact with the cleaning roller, and the resistance member is formed with a chevron-shaped portion with a side surface thereof extending in the rotational direction of the cleaning roller. The inkjet printer is characterized in that each side surface of the chevron-shaped portion has a different shape, so that the rotational resistance of the cleaning roller changes when the carriage moves forward and back.
