PROBLEM TO BE SOLVED: To prevent a suction amount of liquid suction operation by a tube pump from its variation. SOLUTION: The apparatus includes a tube pump for discharging a fluid in a capping means sealing a nozzle forming face of a liquid ejecting head, having a roller member rolling on an inner periphery of a curved part of a tube member by pressing and deforming the curved part and a leak point, a phase detection means for detecting a phase of an orbital motion of the roller member, and a control means for controlling the operation of the tube pump. The control means has a function for stopping the roller member at a predetermined position based on information on the phase of the orbital motion of the roller member detected by the phase detection means.
