There are provided a liquid jet head and a liquid jet recording device capable of enhancing the reliability. A liquid jet head according to an embodiment of the disclosure includes a liquid jet section from which liquid is jetted, an electronic control section electrically connected to the liquid jet section, a main protective member adapted to cover a periphery of the electronic control section, a connection section attached to the electronic control section and adapted to electrically connect an outside of the liquid jet head and the electronic control section to each other, and a connection section protective member configured so as to make a state transition between a protection state of covering the connection section and an exposure state of exposing the connection section.

Liquid jet head and liquid jet recording device

There are provided a liquid jet head capable of dealing with jet of a variety of types of liquid, and at the same time superior in easiness in handling. The liquid jet head includes a main body part having a liquid jet head chip and a cooling section, and an inflow side connection unit and an outflow side connection unit each configured so as to selectively be attached to and detached from the main body part. As the inflow side connection unit, it is possible to select the first inflow side cover unit and the second inflow side cover unit. As the outflow side connection unit, it is possible to select the first outflow side cover unit and the second outflow side cover unit.

A liquid jet head and a liquid jet recording device capable of accurately detecting the temperature of the ink are provided. A liquid jet head according to an embodiment of the disclosure includes a flow channel member provided with a flow channel of a liquid, and having a high heat conduction part disposed so as to have contact with the liquid flowing inside the flow channel, and a low heat conduction part having lower thermal conductivity than thermal conductivity of the high heat conduction part, a temperature detection element disposed outside the flow channel, and attached to the high heat conduction part, and a liquid jet section from which the liquid is jetted.

A liquid ejecting head is mounted on a carriage in which a first positioning hole defined by a first inner surface is provided. The liquid ejecting head includes a first positioning member and a first intermediate member. The first intermediate member includes a first expansion portion being capable of being inserted into a first positioning hole and abutting on the first inner surface by expanding in a radial direction intersecting with an insertion direction of the first expansion portion. The first expansion portion includes a first insertion hole into which the first positioning member is inserted and expands in the radial direction by the first positioning member being inserted into the first insertion hole.

Liquid ejecting head and liquid ejecting recording apparatus

There is provided a liquid jet head capable of preventing a damage of an actuator plate without degrading the quality of characters and images to be recorded on a recording medium. The liquid jet head includes a nozzle plate, an actuator plate provided with an exposed area exposed from the nozzle plate, a nozzle guard provided with an opening section, and a bonding layer disposed at least between the actuator plate including the exposed area and the nozzle guard and bonding the actuator plate and the nozzle guard to each other. The nozzle guard includes a non-contact section continuing throughout an area from a place opposed to the exposed area to an inner circumferential edge of the opening section, and opposed to the actuator plate across the bonding layer, and an alignment section disposed on the opposite side to the non-contact section across the opening section, and carrying out the alignment between the nozzle plate and the nozzle guard.

To provide a flat lighting device used for a liquid crystal display device and the like that can be made thin and lightweight and produced at low cost, the lighting device of the present invention includes a plurality of surface light emitting plates which are two-dimensionally arranged. Each of the plurality of surface light emitting plates includes a light guide portion and a light source portion provided in an end portion of the light guide portion. The light guide portion and the light source portion are integrally provided. The light source portion of a surface light emitting plate two-dimensionally overlaps with the light guide portion of another surface light emitting plate adjacent thereto, so light having a uniform intensity can be emitted above the plurality of surface light emitting plates.
