Problems solved by technology

[0003] However, due to the complex shape of each part, there are many boundaries between parts, so when the ink tube is used to connect the pipe of the ink circulation system and the inkjet head, sometimes the ink overflows from the pipe, and the ink invades the inside of the cap and adheres to the printing surface.

Abstract

Inkjet heads and printers are provided to prevent ink from ingressing into the inside of the cover and attaching to the printed wiring substrate. In one embodiment, there is provided an inkjet head, which has: the head body; Multiple pipelines; Multiple flexible substrates; Reference board; Plate table; Plurality of inner covers, each having an inner surface covering the plate, a first mating face in contact with the side of the inner surface, an outer surface of the opposite side of the inner surface, and a second mating face formed on the outer surface side, using the flexible base plate bending posture configuration of the driving circuit on the second mating facial side using the flexible substrate; Plurality of side covers, together with these inner covers to dissipate heat and have an inner surface facing each outer surface, the inner surface side of the third mating face in contact with the second mating face, and the outer surface combined with the printed wiring substrate.

Description

technical field [0001] One embodiment relates to an inkjet head and a printer. Background technique [0002] An inkjet head is provided in the printer main body (inkjet printer main body), and ink is pressurized to discharge liquid droplets. Conventionally, a driver IC for ejection driving is provided in an inkjet head, and a cover is provided outside the driver IC to release heat from the driver IC as a heat sink (for example, refer to Patent Document 1). In addition, the printed wiring board on which the peripheral circuit for driving the driver IC is packaged is provided, and it is necessary to prevent the ink leaked from the interface between parts such as the head body, the cover plate, and the cover or the ink scattered in the form of mist from adhering to the printed wiring board. . Therefore, the intrusion of ink is prevented by pouring a sealing material such as an adhesive into the boundary surface between the parts to perform sealing. Boundary surfaces refer to...
