Abstract

PURPOSE:To set the fitting angle of the blade freely by providing a recessed part to the intermediate part of a surface which is sectioned rectangularly and on the opposite side from a surface pressed against a photosensitive body. CONSTITUTION:The resin blade 3 is formed of resin in the rectangular section shape, the recessed part 4 is formed in the intermediate part on the opposite side from the side where the photosensitive body 1 is pressed, and the resin blade 3 is fitted to a blade fixture 2 at a fitting angle B. This resin blade is pressed against the photosensitive body 1 to form a press-contacting angle A. The resin blade 3 is therefore energized in a belt shape. The side, dimensions, etc., of the recessed part which is formed in the intermediate part of the opposite surface from the surface which is pressed against the photosensitive body 1 can be adjusted. Consequently, the fitting angle B can be set optionally.

Description

【発明の詳細な説明】 〔産業上の利用分野〕 本発明は電子写真方式印刷装置のクリーニング機構に関

グする圧接式樹脂ブレードに関する。DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention relates to a cleaning mechanism for an electrophotographic printing apparatus, and more particularly to a pressure-contact type resin blade that uses a resin material and cleans the photoreceptor by pressing it against the photoreceptor.

〔従来の技術〕[Conventional technology]

従来、この種の圧接式樹脂ブレードは樹脂材料の形状は

This resin blade 5 has a rectangular cross section, and the pressure contact angle A and the mounting angle C are close to each other.

〔発明が解決しようとする課題〕[Problem to be solved by the invention]

がある。The above-mentioned conventional pressure welding type resin blade has a rectangular cross-sectional shape, so in order to obtain an appropriate pressure contact force and to perform normal leaning, it is necessary to set the appropriate angle when the blade is in pressure contact with the photoreceptor surface. The disadvantage is that it is limited.

本発明の目的は、かかるブレードの取付は角を自由に設
定できる圧接式樹脂ブレードを提供することにある。An object of the present invention is to provide a pressure-welding resin blade whose angle can be freely set.

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

本発明の圧接式樹脂ブレードは、樹脂の断面形状を長方

凹部を形成したことを特徴としている。The press-contact type resin blade of the present invention is characterized in that the cross-sectional shape of the resin is rectangular, and a recess is formed in the middle portion on the side opposite to the side pressed against the photoreceptor.

〔実施例〕〔Example〕

次に、本発明の実施例について図面を参照して説明する
。Next, embodiments of the present invention will be described with reference to the drawings.

第１図は本発明の一実施例を示す圧接式樹脂ブレードの

ができる。As shown in FIG. 1, in this embodiment, a resin blade 3 attached to a tool 2 at an angle B is pressed against a photoreceptor 1 rotating in the direction of the arrow, forming a pressure angle A. This resin blade 3 is formed in a dogleg shape, and a four part 4 is formed in the middle part of the surface opposite to the surface that is pressed against the photoreceptor 1. By adjusting the size and other dimensions of the recess 4, the angle B for attaching the resin blade 3 can be arbitrarily set, so that the blade 3 can be attached appropriately.
