摘要： Provided is a liquid-jet apparatus which can suppress liquid consumption by preventing air that can turn into bubbles from entering a liquid introducing columnar body in replacement of a liquid storage member and thus reducing a frequency of execution of a cleaning operation for discharging the bubbles inside a liquid passage. An ink introducing needle in a printer includes: a needle-like protrusion having a tapered portion whose diameter is gradually increased toward its base from its tip; and a straight portion formed linearly and continuously from the tapered portion. In the tapered portion of the needle-like protrusion in the ink introducing needle, groove portions extending to an edge portion of the tapered portion are provided.

摘要： A method of producing a liquid ejection head comprising: a flow path forming substrate in which a space including pressure generating chambers and an ink reserving chamber is formed; a nozzle plate which is stacked on one face of the flow path forming substrate; and a vibration plate which is stacked on the other face of the flow path forming substrate is provided. The flow path forming substrate is formed by a monocrystal silicon substrate in which a plane of crystal plane orientation of (110) is the surface. When the ink reserving chamber penetrating from the one face of the substrate to the other face is formed by anisotropically etching the (110) plane of the flow path forming substrate, a (111) plane which is inclined with respect to the (110) plane is caused to appear, whereby a step portion which extends in the plate face direction of the substrate, and in which an inner wall face of the flow path forming substrate on the side of the nozzle plate is inward projected is formed on an inner wall face of the ink reserving chamber.

摘要： A liquid jet head and apparatus prevent an increase in the viscosity of liquid in the liquid path during long term storage. The recording head has a liquid path unit 1 with nozzle openings 8, pressure generation chambers 7, liquid reservoirs 9, and a diaphragm 5, and a head case 2 bonded to the liquid path unit 1. A damper chamber 12 for releasing pressure change inside the liquid reservoir is formed at a part of the head case or seal plate 5 corresponding to the liquid reservoir 9. A release path 14B for releasing pressure in the damper chamber to the air is formed in the head case. A control path 14A communicating with the damper chamber and release path and having a specific flow resistance restricting dispersion of moisture vapor from the liquid is formed in the head case and/or seal plate.
