20130070025 | LIQUID EJECTION HEAD AND IMAGE FORMING APPARATUS INCLUDING SAME - A liquid ejection head including a nozzle plate having a nozzle array constructed of multiple nozzles from which liquid droplets are ejectable; a channel plate in which grooves that form part of multiple pressure chambers respectively communicating with the multiple nozzles are provided with partition walls interposed therebetween, a wall member that covers the grooves to form part of walls of the pressure chambers, and multiple first through-holes formed in the channel plate to connect the nozzles and the pressure chambers, respectively. The multiple first through-holes are provided with partition walls interposed therebetween, and each of the multiple first through-holes has a first opening and a second opening. The second opening is offset from the first opening in a direction in which the nozzle arrays extend. Each of the multiple first through-holes further has a portion between the first and second openings to change a direction of flow of liquid. | 03-21-2013 |
20130070026 | LIQUID EJECTION HEAD AND IMAGE FORMING APPARATUS INCLUDING SAME - A liquid ejection head including a nozzle plate having a nozzle array constructed of multiple nozzles, a channel member that forms multiple individual channels communicating with the multiple nozzles, a pressure generator to pressurize liquid within the multiple individual channels, and a common channel member that forms a common channel from which the liquid is supplied to the multiple individual channels. The channel member includes a first surface facing the common channel, a second surface provided at both ends of the channel member and protruding beyond the first surface toward a direction opposite a direction of flow of the liquid, and a third surface that connects the first and second surfaces. At least a gap between the common channel member and a part of the second surface is sealed by a seal member that forms a wall of the common channel between the channel member and the common channel member. | 03-21-2013 |
20130242001 | LIQUID-JET HEAD AND IMAGE FORMING APPARATUS - A liquid-jet head includes a channel plate forming an individual liquid chamber in communication with nozzles configured to eject liquid drops, a wall surface member forming a wall surface of the individual liquid chamber, and a drive unit disposed on the wall surface member side and configured to generate a pressure applied to a drive region inside the individual liquid chamber. In the liquid-jet head, a fluid resistance part is formed by disposing an island part in a liquid supply channel configured to supply a liquid to the individual liquid channel, and the island part includes a gradient part on the channel plate side, at least a part of the gradient part being formed such that the part of the gradient part faces the drive region inside the individual liquid chamber. | 09-19-2013 |
