Abstract

PURPOSE:To keep stable and strong paper feeding power by constituting both a heat roller and a pressure roller as a roller with a gear. CONSTITUTION:The heat roller 1, the pressure roller 2, a heat roller gear 3 and a pressure roller gear 4 are included to constitute the above part. The heat roller 1 gives stable rotating power to the pressure roller 2 in virtue of the heat roller gear 3 and the pressure roller gear 4, so that the stable paper feeding power is kept even when a paper passes between both rollers 1 and 2. Thus, the stable and strong paper feeding power can be kept whether or not the paper exists between both rollers 1 and 2.

Description

【発明の詳細な説明】 〔産業上の利用分野〕 本発明は、電子写真系プリンタ用定着部に関する。[Detailed description of the invention] [Industrial application field] The present invention relates to a fixing unit for electrophotographic printers.

〔従来の技術〕[Conventional technology]

従来の電子写真系プリンタ用定着部は、プレッシャロー

う欠点があった。However, in the above-mentioned conventional fixing unit for electrophotographic printers, the rotational force of the pressure roller is applied only by the friction of the contact portion with the heat roller. This method has the disadvantage that the contact area of the rollers becomes smaller and the paper feeding force decreases.

〔課題を解決するための手段〕[Means to solve the problem]

用紙送り力を保つことが可能になるという効果がある。In the fixing unit for an electrophotographic printer of the present invention, both rollers have gears, and the rotational force of the heat roller is transmitted to the pressure roller by the gears, so that the paper is placed between the two rollers. Regardless of whether or not this is the case, the effect is that it is possible to maintain a stable and large paper feeding force.
