するインク滴を吸い取るインクジェットプリンタの偏向
電極クリーナーに関するものである。DETAILED DESCRIPTION OF THE INVENTION (Technical Section*) The present invention relates to a deflection electrode cleaner for an inkjet printer that sucks up ink droplets that land on the deflection electrode of an inkjet printer.

る。(Prior Art) As schematically shown in FIG. 1, an inkjet printer ejects inkjet from a nozzle 1,
The VC charges the ink droplets according to the desired pattern.
Deflection type Jl+ 3 depending on the amount of charge
The ink particles 4 are deflected to record a desired pattern on the recording medium 5, and the uncharged ink particles are collected in the gutter 6 without being deflected.

があり公知である。However, when the inkjet ejected from the nozzle 1 passes through the deflection electrode 3 and prints on the recording medium 5, a considerable amount of ink mist is generated in the vicinity.
When air jet is ejected from the nozzle, if air such as bubbles is ejected at the same time, the particles will not flow uniformly and will scatter in all directions. These ink droplets etc. are applied to the deflection electrode 48
When the first contact occurs and accumulates, it causes deflection and disturbance of the field, resulting in printing distortion and even one-time discharge. As countermeasures against this problem, there are known methods, such as those provided with a device for cleaning the deflection electrode (for example, Japanese Patent Laid-Open No. 51-118919), and those using a vacuum hop (for example, Japanese Patent Laid-Open No. 51-93823).

and 9, valve 8 opens only to the outside of the container, valve 9 opens to screw 1-1011, but deflection electrode 3' 1111
It is a structure that cannot be opened. When the deflection electrodes 3' and 3'' finish moving one line of the recording medium together with the carriage, the piston 10 collides with the wall surface 11, and the deflection electrode 3

The restoring force of 3 returns to the original position (tk. The front valve 8 is closed 11, and the valve 9 is opened to suck air from the porous deflection mold 1@3', creating an air gap between the deflection electrodes. The ink mist and ink droplets that have landed are sucked in, and these operations are performed every time the carriage moves by one line.

Since it is designed to suck ink mist and ink droplets that have landed on the electrode, there is no need to provide a vacuum hop or a cleaning device for the deflection electrode, and the device is simple: it has the advantage of being configured in one nobact.
