Original Abstract Submitted
A pump device, that supplies a liquid reserved in a reservoir to a first liquid supply destination and a second liquid supply destination, includes: a first pump whose suction port and discharge port are not switched between at forward rotation and at reverse rotation; a second pump whose suction port and discharge port are switched each other between at forward rotation and at reverse rotation; a power source that optionally switches a rotation direction of the power source; a shaft member that is rotated by a driving force from the power source; and a control device that controls at least a rotation direction of the power source. Further, the first pump and the second pump are provided on the shaft member, the first pump is connected to the first liquid supply destination, and the second pump is connected to the second liquid supply destination.
