Patent ID: 8042921

Claim:
A valve device provided in a passage forming member, the passage forming member having a plurality of passages for guiding a fluid stored in a fluid reservoir, the fluid reservoir being capable of being connected to and disconnected from the passage forming member, the device comprising: a plurality of valve members provided in the passages respectively, wherein each valve member is capable of opening and closing the corresponding passage; and an actuating mechanism for moving the valve members, wherein, as the fluid reservoir is connected to and disconnected from the passage forming member, the actuating mechanism causes the valve members to open and close the passages concurrently, wherein the actuating mechanism includes: a rotation member which is rotatable between a first position and a second position relative to the passage forming member, wherein, when the rotation member is located in the first position, each valve member opens the corresponding passage, and, when the rotation member is located in the second position, the valve member closes the corresponding passage; and a restricting member which is moveable between a restriction position and a non-restriction position, wherein, when being located in the restriction position, the restricting member restricts movement of the rotation member so that the rotation member is located in the second position, and, when being located in the non-restriction position, the restricting member does not restrict the movement of the rotation member, and, when the fluid reservoir moves to a connection position at which the fluid reservoir is connected to the passage forming member from a disconnection position at which the fluid reservoir is disconnected from the passage forming member, the restricting member is pressed by the fluid reservoir, and is moved to the non-restriction position from the restriction position.
