Patent ID: 8449069

Claim:
A liquid-jetting apparatus comprising: a liquid-jetting head which has a liquid-jetting surface provided with first nozzles and second nozzles opening thereon and which jets liquids of mutually different types from the first and second nozzles respectively; a cap which is driven between a capping position at which the cap is brought in tight contact with the liquid-jetting surface of the liquid-jetting head and a retracted position at which the cap is separated from the liquid-jetting surface; a cap driving member which moves in a predetermined first direction to drive the cap; a first gas discharge valve and a second gas discharge valve which are constructed so that any bubble is discharged from a first liquid supply member connected to the liquid-jetting head for supplying the liquid to the first nozzles and a second liquid supply member connected to the liquid-jetting head for supplying the liquid to the second nozzles respectively; a first valve opening/closing member which opens/closes the first gas discharge valve and a second valve opening/closing member which opens/closes the second gas discharge valve; a first gas discharge driving member and a second gas discharge driving member which are arranged while being aligned in the first direction, which move in a second direction intersecting the first direction along an arrangement surface thereof to drive the first valve opening/closing member and the second valve opening/closing member respectively; and a driving source which moves both of the first gas discharge driving member and the second gas discharge driving member in the second direction, wherein: the cap driving member is provided with a first stopper which is positioned on the arrangement surface of the first gas discharge driving member and the second gas discharge driving member and which regulates the movement of the first gas discharge driving member and the second gas discharge driving member in the second direction; the cap driving member is further movable in the first direction without changing the position of the cap after the cap arrives at the capping position; and a position of the first stopper is switched to a first regulation position at which the movement of the first gas discharge driving member is regulated, a second regulation position at which the movement of the second gas discharge driving member is regulated, and an allowance position at which the movement of both of the first gas discharge driving member and the second gas discharge driving member is not regulated, in accordance with the movement of the cap driving member in the first direction after arrival at the capping position.
