Ink-jet recording device and cleaning part of the same recording device

Abstract

In an inkjet recording apparatus which is equipped with a recording head having a discharge opening surface on which plural different-length discharge opening arrays are disposed in parallel, plural wipers are provided for wiping off the discharge opening surface in a direction intersecting the discharge opening arrays. Each of the plural wipers has a main wiping section corresponding to the length of the corresponding discharge opening array, notch sections capable of avoiding convex portions or concave portions located in the vicinity of both the ends of the corresponding discharge opening array, and a sub wiping section corresponding to an area other than the discharge opening array and the convex or concave portions, whereby it is possible to effectively wipe off the discharge opening surface by a simple structure and easily output a high-quality recording result by an inexpensive mechanism.

Description

technical field [0001] The present invention relates to an inkjet recording apparatus that ejects ink from a recording head having a plurality of ejection orifice arrays to record on a recording material, and relates to a new configuration of a cleaning unit of the inkjet recording apparatus. Background technique [0002] Recording devices with functions such as printers, copiers, facsimile machines, etc., or recording devices used for output devices such as composite electronic devices including computers and word processors, and workstations, which are composed of paper, cloth, plastic film, etc. based on recorded information , OHP film and other recording material (recording medium) to record images (including characters and signs, etc.). In a serial recording device that records while performing main scanning in a direction intersecting with the transport direction of the recording medium, an image is recorded with a recording head (recording device) mounted on a carriag...

AI Technical Summary

Problems solved by technology

[0007] However, conventionally, in an inkjet recording device equipped with a cleaning unit (wiping device) that wipes a plurality of ejection port arrays that eject different inks with a plurality of blades corresponding to each ejection port, there are technical problems that need to be solved. , That is, after the scraping process, it is impossible to effectively prevent the various inks remaining on the ejection orifice from invading into different ink ejection orifice arrays, and it is easy to cause color mixing caused by different inks mixing with each other, and it is easy to cause recording caused by the color mixing. Image quality degrades

In addition, when protrusions (protrusions) and recesses that cannot be avoided due to the manufacturing method and internal structure on the ejection port face are formed on the end of each ejection port array, the blade touches these protrusions, or Hanging on the concave part, etc., there is also a technical problem that the surface of the discharge port (especially the part of the discharge port array) cannot be wiped sufficiently
