Abstract

PURPOSE:To provide the titled apparatus capable of detecting and controlling ink liquid pressure and an ink residual amount in high sensitivity with good detection accuracy, constituted so as to detect the deformation and the displacement amount of a flexible membrane forming a part of an ink supply passage by a liquid pressure detecting means due to electrostatic capacity. CONSTITUTION:Constant-voltage is applied between the movable electrode 12 on a flexible membrane 30A for hermetically sealing the ink in an ink chamber 23 and the fixed electrode 34 on a support table 33. The movable electrode 32 on the flexible membrane 30A is moved corresponding to the change in the liquid pressure of the ink in the ink chamber 23 while the distance (d) between both electrodes is changed and the liquid pressure is detected by measuring the electrostatic capacity C of said electrodes.
