The flexible wiring board is bendable towards one of a front surface side and a back surface side of the substrate and includes a bending line. The bending line is formed by bending the flexible wiring board along a bending direction crossing a longitudinal direction of the wires. The bending line contains the wires. Both ends of the flexible wiring board in the bending direction are located on the bending line. A distance between one of the wires located closest to one end of the flexible wiring board and the one end is larger on the bending line than in another part of the flexible wiring board.

  • Publication number: 20100141710
    Abstract: A nozzle device for an inkjet printhead includes a substrate assembly defining an ink supply; a chamber-defining layer defining a nozzle chamber in fluid communication with a nozzle opening and the ink supply; and an actuating arm coupled to the substrate assembly and terminating in a paddle separating the ink supply and nozzle chamber, the arm including a thermal bend portion proximal to the substrate assembly and configured to bend during actuation so that the paddle moves and causes ink within the nozzle chamber to be ejected out through the nozzle opening. A portion of the chamber-defining layer is supported by the thermal bend portion and the substrate assembly.

  • Patent number: 7712876
    Abstract: An inkjet printhead that has an array of nozzles arranged in adjacent rows, each nozzle having an ejection aperture and a corresponding actuator for ejecting printing fluid through the ejection aperture, each actuator having electrodes spaced from each other in a direction transverse to the rows. It also has drive circuitry for transmitting electrical power to the electrodes. The electrodes of the actuators in adjacent rows have opposing polarities such that the actuators in adjacent rows have opposing current flow directions. By reversing the polarity of the electrodes in adjacent rows, the punctuations in the power plane of the CMOS can be kept to the outside edges of the adjacent rows. This moves one line of narrow resistive bridges between the punctuations to a position where the electrical current does not flow through them. This eliminates their resistance from the actuators drive circuit.
