【発明の詳細な説明】 (産業上の利用分野) 本発明は、自己放電によって生成した空気イオンを用い

成する。その空気イオンによって帯電体Xの電荷を中和
する。(Prior Art) Conventionally, a static eliminator for removing static electricity of a charged body is used by attaching an electrostatic copying machine, a facsimile or the like. For example, as shown in FIG. It is known that a plurality of conductive fibers b are held in a direction perpendicular to the charged body X and are grounded via a conductive wire c extending from the conductive body a. The static eliminator moves the charged body X in contact with or close to the conductive fiber b and moves the charged body X to generate air ions by using the electrostatic energy of the charged body X. The electric field from the charged body X is grounded. Collected in the conductive fibers b, and the air is ionized by the electric field to generate air ions. The air ions neutralize the charge of the charged body X.
この種の除電装置は、導電性繊維bの切断端dが帯電体
Xに対向しており、該切断端dに電界が集中して所謂先
端放電によって自己放電し易く効果的とされている。In this type of static eliminator, the cut end d of the conductive fiber b is opposed to the charged body X, and the electric field is concentrated on the cut end d so that the self-discharge easily occurs due to so-called tip discharge.
また、該除電装置の導電性繊維bは、導電体aに縦方向
に保持されて、該導電性繊維bが帯電体Xに接触したと
きに自由に撓んで該帯電体Xの形状やその凹凸に対して
万遍なく除電することができる。Further, the conductive fiber b of the static eliminator is vertically held by the conductor a, and when the conductive fiber b comes into contact with the charged body X, the conductive fiber b is freely bent and the shape of the charged body X or its unevenness is obtained. It is possible to eliminate static electricity evenly.
しかし、導電性繊維bは、除電の際に帯電体Xが接触し
て該導電性繊維bが撓んだときに、該導電性繊維bの抜
けや切断が起こる不都合がある。また、導電性繊維bの
束を縦方向に導電体aに保持させなければならないこと
から、導電体aに強固に固定することが困難であり、こ
のため導電性繊維bの抜け落ちが避けられない。該除電
装置を静電複写機やファクシミリ等に取り付けた際に、
その抜け落ちた導電性繊維によって、画像の汚れや半導
体部品の誤動作等を生じる不都合がある。However, the conductive fiber b has a disadvantage that the conductive fiber b may come off or be cut when the charged body X is contacted and the conductive fiber b is bent during static elimination. Further, since the bundle of the conductive fibers b must be held in the conductor a in the vertical direction, it is difficult to firmly fix the bundle to the conductor a, and therefore the conductive fibers b cannot be removed. . When the static eliminator is attached to an electrostatic copying machine or a facsimile,
Due to the conductive fibers that have fallen off, there is the inconvenience of causing image stains and malfunctions of semiconductor components.
(発明の解決すべき課題) 以上の不都合を解消して本発明は、自己放電し易く、帯
電体の形状に即して除電を行う従来の性能を維持して、
帯電体が接触しても導電性繊維が抜けや切断を起こすこ
とのない構造簡単な除電装置を提供することを目的とす
る。(Problems to be Solved by the Invention) The present invention eliminates the above-mentioned inconveniences, and the present invention is easy to self-discharge, and maintains the conventional performance of removing static electricity according to the shape of the charged body,
It is an object of the present invention to provide a static eliminator having a simple structure in which conductive fibers do not come off or are cut even when a charged body comes into contact therewith.
(課題を解決するための手段) 前記の目的を達成するため本発明は、絶縁材料からなる
可撓性シート部材の下縁部の側面に、複数の導電性繊維
を水平方向に配列させて接着材で該導電性繊維の表面を
露出させて支持し、該導電性繊維を接地したことを特徴
とする。(Means for Solving the Problem) In order to achieve the above-mentioned object, the present invention has a plurality of conductive fibers arranged in a horizontal direction and bonded to a side surface of a lower edge portion of a flexible sheet member made of an insulating material. The surface of the conductive fiber is exposed and supported by a material, and the conductive fiber is grounded.
また、前記導電性繊維は、除電時に帯電体の進行方向に
対して前記シート部材の裏側に接着したことを特徴とす
る。Further, the conductive fiber is adhered to the back side of the sheet member in the traveling direction of the charged body during static elimination.
また、前記シート部材の下縁に縦方向に複数の切れ目を
設けたことを特徴とする。Further, a plurality of cuts are provided in the vertical direction at the lower edge of the sheet member.
また、前記導電性繊維を帯電体に対向する側を露出して
前記シート部材と性質を同じくするシート部材で被覆し
たことを特徴とする。Further, it is characterized in that the conductive fiber is covered with a sheet member having the same property as the sheet member by exposing the side facing the charged body.
(作用) 本発明の除電装置は、前記シート部材の下縁の直下に帯
電体を接近又は接触させて該帯電体を水平移動させて除
電を行う。(Operation) In the static eliminator of the present invention, the charged body is moved close to or below the lower edge of the sheet member to horizontally move the charged body to perform static elimination.
該導電性繊維は、その切断端でなくその外周面が帯電体
に対向するが、該繊維の直径が10μm程度であれば、そ

て導電性繊維を露出させておくことにより、その外周面
の無数の突端が放電開始点となり、導電性繊維の切断端
の先端による放電と同等の放電が可能となる。The outer peripheral surface of the conductive fiber is opposed to the charged body, not the cut end, but if the diameter of the fiber is about 10 μm, the outer peripheral surface becomes a microscopically complicated rough surface. There is. Therefore, by exposing the conductive fibers, the innumerable projections on the outer peripheral surface serve as discharge starting points, and discharge equivalent to the discharge by the tips of the cut ends of the conductive fibers becomes possible.
前記シート部材は、帯電体に接触した場合にその外力に
より撓み、その外力が導電性繊維に及ぶのを抑制する。
該導電性繊維は、水平方向に配列されて固定されている
のでシート部材の撓みによる外力を受けない。When the sheet member comes into contact with the charged body, the sheet member is bent by the external force and suppresses the external force from reaching the conductive fiber.
Since the conductive fibers are arranged and fixed in the horizontal direction, they are not subjected to an external force due to the bending of the sheet member.
また、前記導電性繊維を帯電体の進行方向に対してシー
ト部材の裏側に接着して、帯電体との直接の接触を防止
可能としている。Further, the conductive fiber is adhered to the back side of the sheet member in the traveling direction of the charged body to prevent direct contact with the charged body.

導電性繊維に伝えることなく吸収する。Furthermore, when the sheet member has a plurality of fine strips formed on the lower edge of the sheet member and the surface of the charged body has minute irregularities, even if the sheet member comes into contact with the sheet member, the external force generated at that time is conducted. Absorb without transmitting to the sex fiber.
更にまた、該導電性繊維を被覆して接触から保護し、接
着固定を確実にする。Furthermore, the electrically conductive fibers are coated to protect against contact and ensure adhesive fixing.

ように、前述の従来の装置と同等な除電効果がある。By grounding the conductive fiber 1 through the ground wire 4, the electric field from the charged body X is collected in the conductive fiber 1 and self-discharged, and air is ionized by the discharge to generate air ions. The air ions neutralize the charge of the charged body X. As shown in the second drawing, the outer peripheral surface of the conductive fiber 1 faces the charging body X, and the diameter of each fiber 1 is about 10 μm. Microscopically, it has a complicated rough surface. Therefore, if the conductive fiber 1 is exposed, the innumerable tips of the outer peripheral surface serve as a discharge start point and are self-discharged. As shown in Table 1, the static elimination effect of the static eliminator of this embodiment at this time has the same static elimination effect as that of the above-described conventional device.

防止されて除電が行える。 Further, when the charged body X comes into contact with the sheet member 2 and an external force is applied to the sheet member 2, the entire sheet member 2 bends to absorb the external force, and the conductive material held by the sheet member 2 is electrically conductive. The external force is hardly transmitted to the fiber 1. As a result, the charged body X is prevented from directly contacting the conductive fiber 1 and the charge can be removed.

When there is a minute convex portion on the surface of the charged body X,
Only the portion of the cut 7 bends and escapes the external force generated by the contact of the convex portion, and the external force at that time is prevented from reaching the conductive fiber.
