PROBLEM TO BE SOLVED: To provide a liquid pump having a long life and capable of simultaneously delivering a plurality of liquids from a single driving source and also to provide an inkjet printer equipped with such a pump. SOLUTION: The liquid pump 15 comprises a liquid reservoir 27 having two and more liquid reserving chambers which store at least two or more kinds of liquids, a connecting means 28 which communicates each liquid reserving chamber of the liquid reservoir 27, a pressure adjusting means 29 which communicates with the connecting means 28 and switches the internal pressure of the liquid reserving chambers of the liquid reservoir 27 alternatively to negative pressure or positive pressure, an inflow tube 23 having an inflow valve 25 which lets the liquid flow in the liquid reserving chamber of the liquid reservoir 27, an outflow tube 37 having a discharging valve 36 for discharging the liquid of the liquid reserving chamber of the liquid reservoir 27 and a liquid surface adjusting mechanism 39 serving as a flow-path resistance variable means for adjusting the amount of liquid in the liquid reserving chamber according to the height of the liquid surface of the liquid in the liquid reserving chamber of the liquid reservoir 27. The inkjet printer provided with such a liquid pump is also disclosed. COPYRIGHT: (C)2008,JPO&INPIT |
