Abstract
According to the present invention, there is disclosed a capping device for an ink jet printer which is constructed such that a cap supporting member 14, adapted to move from the non-capping position to the capping position by the thrust action of a carriage 3, is arranged on the home position side of the ink jet printer so that the outer end part of the cap supporting member 14 is displaced toward the nozzle surface of a printing head 4 with the aid of a guide surface 15b having an inclined surface 15a, until a cap 5 on the cap supporting member 14 is brought into close contact with the nozzle surface of the printing head 4 with an adequate intensity of thrust force by means of a turnable lever 8 operatively connected to the inner end of the cap supporting member 14, while resilient force of a cap spring 11 is exerted on the base end part of the turnable lever 8 so as to normally bias the cap supporting member 14 in the direction toward the printing head 4.
