The main body portion includes an ink container that contains ink, and a solvent container that contains a solvent. The print head includes a nozzle connected to the ink container to discharge the pressurized and supplied ink, a charging electrode that charges ink particles discharged from the nozzle, a deflection electrode that deflects the ink particles charged by the charging electrode, and a gutter that collects the ink. In addition, a head mounting unit for cleaning the print head is provided. The head mounting unit is connected to a solvent vapor suction path for suctioning solvent vapor generated therearound.

Abstract: An inkjet recording device having a print head cleaning function of preventing a cleaning liquid from spilling around the inkjet recording device and storing the cleaning liquid used for cleaning in a highly airtight container. The inkjet recording device includes a main body including an ink container accommodating an ink used to perform printing on a print target, and a cleaning liquid container that accommodates a cleaning liquid; a print head including a nozzle that is connected to the ink container to discharge the ink which is pressurized and supplied, a charging electrode that charges ink particles, a deflection electrode that deflects the ink particles charged by the charging electrode, and a gutter that recovers the ink particles which are not used for the printing; and a head cleaning unit including a cleaning nozzle that discharges the cleaning liquid, and an insertion port into which the print head is insertable.

Abstract: The present invention provides an inkjet recording device capable of automatically cleaning the head tip and a cleaning method for inkjet recording apparatus. An inkjet recording apparatus has a printhead that receives a supply of ink and prints, a main unit that supplies said ink to said printhead, and a cleaning unit that has a cleaning tank into which said entire printhead is inserted and injects a cleaning solution from a cleaning nozzle to said printhead for cleaning. The cleaning unit has a cleaning nozzle that sprays cleaning liquid into the cleaning tank and a cleaning base section that has a housing section that accommodates the tip of the printhead and allows said cleaning liquid to flow into the housing section. The cleaning liquid is allowed to flow into the housing section to clean the tip of the printhead.

Abstract: Provided is an inkjet recording device capable of facilitating cleaning of a print head, and easily recovering a solvent (cleaning liquid) that is used for cleaning. An inkjet recording device includes a print head that receives a supply of ink to perform printing; and a main body that includes an ink container to contain the ink and a solvent container to contain a solvent, and that supplies the ink in the ink container to the print head. Further, the inkjet recording device includes a cleaning tank, a cleaning nozzle, and a recovery container. Then, the print head is set inside the cleaning tank, the solvent is sprayed from the cleaning nozzle to clean the print head, and the solvent after cleaning is recovered by the recovery container.

Abstract: The purpose of the present invention is to provide a replenishment container and an inkjet recording device that are capable of reducing staining by ink or a solvent during ink or solvent replenishing. The replenishment container comprises a storage member having an opening formed therein and having a storage chamber that stores ink or solvent, a stopper member that seals the opening of the storage member, and a lid member that covers the stopper member. The replenishment container is characterized by: comprising a seal member that has a throughhole between the stopper member and the lid member; the lid member having a throughhole that is opened concentrically with the throughhole of the seal member; and the inner diameter of part or all of the throughhole in the seal member being smaller than the inner diameter of the throughhole in the lid member.

Abstract: A cartridge-type inkjet recording device that can accurately and easily connect a cartridge-type replenishing liquid bottle to an inkjet recording device is presented herein. This cartridge-type inkjet recording device includes a liquid reservoir to which a replenishing liquid bottle can be attached or removed. The liquid reservoir has a liquid replenishment opening for replenishing liquid from the cartridge-type replenishing liquid bottle. The liquid reservoir also has a cam that is provided to the periphery of the liquid replenishment opening, engages a portion of the cartridge-type replenishing liquid bottle, and moves the cartridge-type replenishing liquid bottle in the vertical direction, and a cam operation section that operates the cam.

Abstract: A liquid container includes a coupling part that is configured to engage with a refill liquid container. The coupling part includes a pipe unit that, when the liquid container is in use, is projected upward in a vertical direction of the liquid container. The coupling part also includes a plane part that is disposed around the pipe unit.

Abstract: A gas-liquid separator includes a casing with a cylindrical chamber inside, a gas-liquid 2-phase inlet pipe which is attached to a wall of the casing and connected to the chamber, a gas outlet pipe for discharging the gas of a gas-liquid mixture flowing into the chamber, and the gas-liquid 2-phase outlet pipe for discharging the liquid as a most part of the gas-liquid mixture flowing into the chamber. A gap is formed around the gas-liquid outlet pipe in the chamber for separating the mixture into liquid and gas using the surface tension and suction force. The gas-liquid separator is installed in the inkjet recording apparatus, especially in the print head. The print head is filled with the solvent gas so as to be suctioned from the gutter to reduce the solvent consumption.
