。[Claims for Utility Model Registration] (1) In an ink supply device that supplies ink at a predetermined pressure to an ink droplet generator of an inkjet printer, a first device that generates a pressure change by a reciprocating plunger or piston; a second pump section that generates a pressure change by an electrostrictive element that is displaced in accordance with the frequency of the applied potential; and a second pump section that generates a pressure change when the ink pressure is below a predetermined level. 1. An ink supply device for an inkjet printer, comprising a control section that operates the second pump when the ink pressure reaches the level. (2) The ink supply device for an inkjet printer according to claim 1, wherein the control section detects the ink pressure based on a pressure sensor signal. (3) The inkjet supply device for an inkjet printer according to claim 1, wherein the control section determines that the ink pressure has reached the level when a predetermined time has elapsed.
