Abstract

PURPOSE:To eliminate a polishing process after molding a paper feed roll to reduce the cost thereof, by molding the paper feed roll with the use of molding dies having surfaces with irregularities. CONSTITUTION:An irregular part is formed on the outer surface of a paper feed roll 1 so that it is prevented from slipping. This paper feed roll 1 is mounted with the use of molding dies formed therein with irregularities. Accordingly, it is possible to eliminate a step of polishing the outer surface of the roll, and further it is possible to select the shape of irregularities in accordance with the characteristic of sheets to be fed.

Description

【発明の詳細な説明】 〔産業上の利用分野〕 本発明は給紙機構をもつ印字装置の用紙給紙部に使用す
る給紙ローラに関する。DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention relates to a paper feeding roller used in a paper feeding section of a printing device having a paper feeding mechanism.

〔従来の技術〕[Conventional technology]

従来、この種の印字装置に使用する給紙ローラの表面処
理方法は、成形後研磨加工して給紙特性を向上させるた
めに表面凹凸を与えていた。Conventionally, the surface treatment method for paper feed rollers used in this type of printing apparatus has been to polish the rollers after molding to provide surface irregularities in order to improve paper feed characteristics.

〔発明が解決しようとする問題点〕[Problem that the invention seeks to solve]

上述した従来の給紙ローラは、表面に凹凸を与えるため
に成形後、研磨加工をしなければならないため、研磨工
数がかかり、高価になるという欠点がある。The above-mentioned conventional paper feed roller has the disadvantage that it requires polishing work after molding in order to give the surface an uneven surface, which requires many polishing steps and is expensive.

本発明の目的は、このような欠点を除去し、安価に構成
できる印字装置用給紙ローラを提供することにある。SUMMARY OF THE INVENTION An object of the present invention is to provide a paper feed roller for a printing device that eliminates such drawbacks and can be constructed at low cost.

〔問題点を解決するための手段〕[Means for solving problems]

本発明の印字装置用給紙ローラの構成は、表面形状に細
かに凹凸のある成形型により成形されたことを特徴とす
る。The paper feed roller for a printing device according to the present invention is characterized in that it is molded using a mold having a finely uneven surface shape.

〔実施例〕〔Example〕

次に、本発明について図面を参照して説明する。 Next, the present invention will be explained with reference to the drawings.
