Problems solved by technology

In addition, when the groove is in contact with the paper (recording medium) during paper feeding, different contact resistance will be generated when the other surface is in contact with the paper. As a result, the conveying speed will change and cause conveying fluctuations.
In addition, in so-called inkjet printers that discharge fine liquid droplets to form images, extremely high paper feeding accuracy is required, so the occurrence of feeding fluctuations due to these grooves is particularly a problem.

Abstract

A transport roller includes: a roller body of which a pair of end surfaces face each other by a press work so as to be in a cylindrical shape; and a high friction layer which contains inorganic particles and is provided on a surface of the roller body. Here, the roller body is provided with a joining portion which is formed by separating the pair of end surfaces. In addition, an average particle diameter of the inorganic particle is larger than a distance between the pair of the end surfaces of the roller body on an outer peripheral surface side thereof.

Description

Technical field [0001] The invention relates to a conveying roller, a conveying unit, and a printing device. Background technique [0002] Various printers have been provided as printing devices in the past. In this type of printer, recording media such as paper are transported to the printing section through a transport roller (paper feed roller) and a driven roller, where it passes through the paper discharge roller (drive roller) and its driven roller (squeeze roller) after printing. ギザロ一ラ) eject the recording medium. [0003] In this type of printer, the paper is clamped between the conveying roller and the driven roller, and the paper is rotated and driven in this state to move the paper in the sub-scanning direction orthogonal to the moving direction of the carriage. Therefore, the paper is transported to the recording position with high precision, and then sequentially fed in according to the printing speed, which requires a high transport force. [0004] Therefore, in order...
