This relates to a so-called charge deflection type inkjet recording device that prints on recording paper by deflecting the inkjet, and in particular, a porous metal member (sintered product) that forms an opening for passing ink droplets at the tip of the carriage. ), the opening is cut diagonally so as to open toward the recording paper side, thereby increasing the ink mist absorbing surface and making it easier to cut out the sintered product.

In the figure, 1 is a carriage, and 2 is a scanning motion of the carriage 1 in the direction of the arrow. 3 is an inkjet head mounted on the carriage 1; 4 is a charging electrode;
5 is a deflection electrode, 6 is a gutter, and 7 is a recording paper.As is well known, ink droplets ejected from the inkjet head 3 are charged at a charging electrode 4 according to a printing information signal, and the charged ink droplets are charged. The ink droplets are deflected by the deflection electrode 5 according to the amount of charge and printed on the recording paper 7, while uncharged ink droplets are captured and recovered by the gutter 6 for reuse. , In the above-mentioned inkjet recording apparatus, conventionally, the carriage 1
An ink mist absorbing plate 8 made of a porous metal member such as a sintered member is provided at the tip of the ink mist absorbing plate 8, and ink droplets are caused to fly through openings 9 provided in the ink mist absorbing plate 8 for passing ink droplets. However, this opening 9 is
As shown in FIG. 2, the cut is oblique to the direction of deflection of the ink droplets, thereby improving electric field shielding and making the opening small in the direction of deflection.

The line cross-sectional view, FIG. 6, is a cross-sectional view taken along the line ■-Vl in FIG. 3. As shown, the opening 9 is cut obliquely across the entire surface so as to open toward the recording paper 7 side. Therefore, as shown in FIG. 7, the ink mist absorption area becomes larger, and the ink mishap occurs when the ink droplet 11 collides with the recording paper 7.
can be absorbed effectively.

とはない。FIG. 8 is a diagram for explaining an example of a method for manufacturing the ink mist absorbing plate 10 according to the present invention, in which 10 is the ink mist absorbing plate according to the present invention, 20 is an upper mold, and 21 is a lower mold. As shown in the figure, the ink mist absorbing plate 10 according to the present invention is formed by die cutting. When removing the upper mold 20, the upper mold 20 can be easily removed without damaging the ink mist absorbing plate 10.
