liquid jet recording device

Abstract

Abstract PURPOSE:To stably emit a recording liquid at the time of recording and to prevent the dripping of said liquid from a nozzle when no recording is performed, by providing a recording liquid tank at a position higher than the nozzle and providing a supply pipe equipped with an opening and closing valve at a position lower than the nozzle, and performing control such that said valve may be opened at the time of recording but closed at the time of non-recording. CONSTITUTION:An ink tank 2 provided at a position higher than the nozzle of a recording head 1, an ink supply pipe 3 equipped with an opening and closing valve 5 provided at a position lower than the nozzle and a control part 6, performing control so that the opening and closing valve 5 is opened at the time of recording but closed at the time of non-recording, are mounted. Therefore, at the recording time, the recording liquid in the recording head 1 is held to a state pressurized by the water head of the ink tank 2 present at a high position and the liquid can be stably emitted. At the time of non-recording, the opening and closing valve 5 provided to the ink supply pipe 3 is closed and, since said supply pipe 3 is present at a lower position, no water head is applied to the liquid and the dripping of the liquid from the nozzle can be prevented.
