Patent ID: 8622510

Claim:
A cap device configured to cover a jetting surface of a liquid jetting head to recover a jetting performance of the liquid jetting head, the cap device comprising: a cap unit which is tiltable in a plane substantially parallel to the jetting surface, and which is configured to come into close contact with the jetting surface of the liquid jetting head; a flexible discharge tube of which one end is connected to the cap unit, which is configured to communicate with an inner space defined by the cap unit and the jetting surface under a condition that the cap unit comes into close contact with the jetting surface, and through which a liquid in the inner space is to be discharged; and a fixing mechanism, which is configured to fix a portion of the discharge tube, other than the one end, to the cap unit so that a displacement of the discharge tube in a horizontal direction is restricted, and which is configured to fix another portion of the discharge tube, other than the one end, to the cap unit so that a displacement of the discharge tube in a vertical direction substantially perpendicular to the horizontal direction is restricted.
