摘要： A liquid discharge head records by generating thermal energy to discharge ink from a discharge port onto a recording medium. The head is provided with a heat dissipating substrate positioned substantially parallel and adjacent to a discharge portion substrate, and a space, which communicates with the outside air, positioned at a surface of the heat dissipating substrate which is opposite the surface of the heat dissipating substrate facing the discharge portion substrate. The space extends in the scanning direction so as to facilitate air flow through the head during carriage movement in order to dissipate heat generated by the head during recording. A cooling fan may be provided to increase the air flow and the consequent heat dissipation.

摘要： The invention prevents drawbacks resulting from the bubble generated at the downstream side of the filter, while minimizing the waste in the ink. The recording head has a sub tank for storing ink supplied from the exterior, and a liquid chamber storing the ink supplied from the sub tank and supplying ink directly to a nozzle for ink discharge. A filter is provided between the sub tank and the liquid chamber. The liquid chamber holds ink of a predetermined amount in such a manner that the ink therein is separated by gas between the filter and the liquid chamber.

摘要： A cartridge is detachably mountable to a holder of an ink jet recording apparatus, so as to be freely reciprocatable to scan across a recording medium and record thereon by discharging ink. The cartridge is defined by a cartridge main body, and is provided with a recording head for discharging ink from plural nozzles formed in parallel on a lower face of the cartridge main body facing the recording medium. A front face of the cartridge main body is provided with an electrical connection portion having cartridge electrodes, which are electrically connectable with corresponding electrodes of the holder. A rear face opposite to the front face is provided with an ink connection portion connectable to corresponding supply ports which supply ink to the recording head from a main tank installed elsewhere on the ink jet recording apparatus. With the cartridge thus structured, the force exerted for connection to the supply port does not affect the precision with which the cartridge is mounted on the holder.

摘要： In an inkjet recording apparatus in which a single ink supply path for hermetically sealing an ink tank and a recording head from the atmosphere is formed by connecting the ink tank to first and second hollow needles. When the ink tank is detached, the flow path is sealed in association with mounting and dismounting of the ink tank, thereby leakage of ink to the outside of the apparatus is prevented.
