摘要:
An ink jet recording apparatus configured to perform recording by discharging ink from a plurality of discharge ports disposed on a recording head. The apparatus includes a cap adapted to cover the plurality of discharge ports disposed on the recording head, a recessed portion defined on a bottom face inside the cap, a suction hole facilitating introducing a negative pressure to the recessed portion, an atmosphere communication hole located outside a range of the recessed portion and communicating with atmosphere, an ink absorber mounted inside the cap to cover the recessed portion, and a suction pump connected to the suction hole and configured to generate a negative pressure. When the plurality of discharge ports is covered with the cap, a projection image obtained when the plurality of discharge ports is projected onto the bottom face exists within the range of the recessed portion.

In a flexible wiring board for use in, for example, a liquid discharge head, wires disposed on a substrate in parallel are covered with a film material. 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. Accordingly, even if the flexible wiring board is bent at a small bend radius, peeling does not easily occur between a base film and a cover film.

A liquid jet recording head includes a recording portion having a recording element substrate provided with a recording element for discharging liquid and a face surface provided with a discharge port for discharging liquid, a recording liquid storing portion for storing the recording liquid supplied to the recording portion, and a coupling member for coupling the recording portion and the recording liquid storing portion. A projecting member is provided on the recording liquid storing portion. The coupling member couples the recording portion and the recording liquid storing portion so that a leading end of the projecting member projects toward an end of the face surface from a side of the recording portion when the recording portion is coupled with the recording liquid storing portion.

In the liquid discharge recording head provided with a stopper member formed of an elastic member to be penetrated by a hollow needle member for liquid supply into a liquid preserving chamber in the recording head, the invention enables smooth insertion of the front end of the needle member into the stopper member without insertion failure. The liquid discharge recording head is provided with a head chip having a nozzle for discharging liquid, and a frame member connected thereto and having a liquid chamber for containing the liquid to be supplied thereto. A hole portion is formed in a portion of the frame member, and joint rubber is pressed into such hole portion. In the joint rubber, there is formed in advance a fissure hole, to be penetrated by a hollow needle provided in the main body of the liquid discharge recording apparatus and having fissures in not less than three directions from the crossing center of the fissures, in a plane perpendicular to the direction of depth of the hole portion.
