Abstract:
1. A liquid jet recording apparatus, comprising: a liquid container for containing liquid; a jetting portion which is disposed lower than a surface of the liquid contained in the liquid container and which includes a plurality of nozzles for jetting the liquid; a conduit communicating the jetting portion with the liquid container; an on-off valve disposed in the conduit and fixed to a frame, the on-off valve permitting the liquid to flow through the conduit when the on-off valve is opened and blocking the flow of the liquid through the conduit when the on-off valve is closed; a liquid storing portion, disposed in the conduit between the on-off valve and the jetting portion, for damping pressure fluctuations of the liquid; pressure measuring means for measuring the pressure of the liquid which flows through the conduit, the pressure measuring means being disposed in the conduit between the liquid storing portion and the jetting portion; and a control portion for controlling the on-off valve to be opened and closed based on a pressure value measured by the pressure measuring means, the control portion being electrically connected to the pressure measuring means and the on-off valve.
