Claims

[Scope of Claim for Utility Model Registration] (1) A print head that has a plurality of ink ejection ports aligned on the front surface for printing by ejecting ink, and a carriage on which the print head is mounted and is provided so as to be movable back and forth. a mountain-shaped cam provided on the carriage; an arm swingably provided near the home position of the printing head; and an arm provided at one end of the arm that engages with the cam. an engaging pin that allows the arm to swing; a cap that is provided at the other end of the arm and that caps the vicinity of the ink ejection port of the print head when the arm swings; and a cap that swings the cap relative to the arm. 1. A capping device for an inkjet printer, comprising: support means for movably supporting the arm; and a stopper for regulating the swinging position of the arm. (2) In claim 1, the support means for the cap comprises a cap shaft embedded in the arm and a cap holder swingably supported on the cap shaft, and the cap is fixed to the cap holder. A capping device for an inkjet printer, characterized in that: (3) In claim 1, the support means for the cap comprises a cap holder to which the cap is fixed, a guide shaft implanted in the cap holder, and a guide shaft provided on the arm so that the guide shaft is slidable. A capping device for an inkjet printer, comprising a long groove that fits into the capping device. (4) In claim 1, the print head is provided to be movable in the direction of movement of the carriage, and includes a stopper for restricting movement of the print head at a position where the cap abuts the front surface of the print head. A capping device for an inkjet printer, characterized in that:
