Field of the Invention The present invention relates to a spur in a sheet material conveying device, and more specifically, it is provided in a recording medium conveying portion of an ink jet recording apparatus for recording on coated paper, and is in point contact with the surface of the sheet material. About the spur that can press the sheet material.

Description of the Related Art Conventionally, in an ink jet recording apparatus, especially in a color printer, as a method of preventing the floating of the paper after recording and applying a tension to the recording surface, the paper is pulled by a roller on the upstream side of the recording surface or air is sucked. It had a structure for adsorption. Further, the recording medium ejecting unit is configured to take measures against the floating of the paper by spur.

は装置が大型化するだけでなく、騒音も問題となった。However, in the above-mentioned conventional example, only the coated paper can be dealt with the roller configuration on the upstream side of the paper discharge, and the OHP and plain paper cannot deal with the print stain. Further, in the structure in which the recording medium is sucked by air, not only the apparatus becomes large, but also noise is a problem.

摩耗すると突起に付着したインクが紙面を一層汚すこと
となる。In the conventional ink jet recording apparatus having a spur structure, the ink adhering to the spur protuberance on the coated paper, the plain paper, and the OHP is different from the white part or other color of the recording medium due to the spur convex shape. Problems such as soiling the recording surface occurred.
Since the coated surface of the coated paper is made of a metal oxide or a metal compound such as Si-based or Mg-based, the protrusions can carry the paper at a higher speed. Even if it is made of a material, it becomes worn and slips on the recording surface on which the ink has been ejected, which causes the image deterioration to move. When the protrusions are worn, the ink attached to the protrusions further stains the paper surface.

の汚れが顕著となる。Further, in the case of a color printer, the influence of spurs in the paper transport section is very different from that of a monochrome (white / black) printer, and even with a small amount of ink adhering to the spurs, the spurs make one revolution next and other colors. The ink on the recording paper ejected at the leading edge causes the ink to become wet again, resulting in color mixing (bleeding)
And the recording surface is soiled. In addition, the tip of the spur protrusion is rounded in the punching of the press due to the wear of the mold, and the contact area with the paper surface becomes large, so that the ink on the OHP / plain paper that does not easily fix the ink gets wet with the ink on the paper surface. Since it is large, stains on the print easily occur due to spurs. In particular,
In the case of OHP, slippage occurs between the spur and the unfixed ink liquid surface on the paper surface, and a trace like a line is easily generated due to the relative speed. In inkjet color printers, not only coated paper but also various recording media such as OHP and plain paper have been used recently. The influence of abrasion causes stains on the printed surface.

体と等速で回転し記録面に影響を及ぼさない。According to the present invention, a SUS material is used so that the spur projections are not worn even when the coated paper for ink jet recording having a hard surface layer is conveyed at high speed. The base material is processed by etching to reduce the curvature of the protrusions, and then hard chrome or nickel chrome plating, or nitriding, product name: tuftride (soft nitriding), carburizing, etc. to increase the surface hardness and to form a coating layer. In the case where the contact surface of is extremely small, wear is minimized. By reducing the protrusion of this spur, the amount of ink adhesion will be small and the influence of transfer to other colors will also disappear, and the protrusion will secure the frictional force of the paper surface even on a wet recording medium and it will not slip, so it is on the driven side. The spur also rotates at the same speed as the recording medium and does not affect the recording surface.

急速に成長する。In the steady state, as shown in FIG. 8 (a), the ink filled in the nozzle d has a uniform surface tension and external pressure at the ejection port surface. When the ink is ejected in this state, the electrothermal converter b in the nozzle d is energized to cause the ink in the nozzle to rapidly rise in temperature beyond nucleate boiling. Then, as shown in FIG. 8B, the ink adjacent to the electrothermal converter b is heated to generate minute bubbles (bubbles), and the ink in the heated portion is vaporized to cause film boiling. The bubbles grow rapidly as shown in c).

When power supply to the electrothermal converter b is finished, the grown bubble is cooled and contracted by the ink in the nozzle d as shown in FIG. It flies from the discharge port. Further, as shown in FIG. 9 (f), the ink comes into contact with the surface of the electrothermal converter b and is rapidly cooled, and the bubbles disappear or shrink to a substantially negligible volume. When the bubbles contract, ink is supplied from the common liquid chamber g into the nozzle d by the capillary phenomenon as shown in FIG. 9 (g) to prepare for the next energization.
