Abstract
A valve opening/closing mechanism includes a rotating shaft, first and second cams provided on the rotating shaft and rotatable together with the rotating shaft, first and second valves, and a rotating mechanism that rotates the rotating shaft. The first and second valves each include a flow channel in which ink flows and an opening/closing member at a position at which the opening/closing member contacts the first or second cam, so as to open or close the flow channel, depending on whether the opening/closing member is in contact with the cam. When the rotating shaft is rotated by the rotating mechanism, rotating positions of the first and second cams are at any of first, second, third or fourth positions.
