て、記録材を機器本体へ供給する際あるいは機器本体か
ら排出する際に、その記録材に接触させて用いる除電器
に関する。[Detailed Description of the Invention] [Industrial field of application] The present invention makes contact with a recording material in a copying machine, a facsimile, a printer, etc. when the recording material is supplied to or discharged from the device body. The present invention relates to a static eliminator used.
この種の除電器として、従来、導電性を有する柔軟材
製ローラおよびローラブラシ（実開昭57−197064号、実
開昭58−172961号公報）等が知られている。As a static eliminator of this type, conventionally, a roller made of a flexible material having conductivity and a roller brush (Japanese Utility Model Laid-Open Nos. 57-197064 and 58-172961) are known.
又、ほぼ等寸法のカーボンファイバーや金属ファイバー
を複数本束ねたものをアルミ板、ローラー等上に等間隔
に並べ、固着させたものがある（例えば特開昭57−6206
3号）。この除電器は、記録材例えば記録紙上に当該束
の先端を接触させて除電を行うものである。In addition, there is one in which a plurality of bundles of carbon fibers or metal fibers of approximately equal size are arranged at equal intervals on an aluminum plate, roller or the like and fixed (for example, JP-A-57-6206).
No. 3). This static eliminator removes static electricity by bringing the tip of the bundle into contact with a recording material such as recording paper.
しかし、上記従来の除電器はいずれも製造工程が多く
高価なものである。接触抵抗が大きく、使用時にファイ
バーが抜けるなど耐久性もない。本考案は、極めて製造
工程が少なくかつ除電効果が優れている除電器であり、
さらに記録材との接触抵抗も小さく、耐久性、メンテナ
ンスが良い除電器を提供することにある。However, each of the above-mentioned conventional static eliminators has many manufacturing steps and is expensive. It has a high contact resistance and has no durability such as the fiber coming off during use. The present invention is a static eliminator that has an extremely small number of manufacturing steps and an excellent static elimination effect.
Another object of the present invention is to provide a static eliminator which has a small contact resistance with a recording material and has good durability and maintenance.
本考案は、導電性線材をコイル状に形成した除電コイ
ルと該除電コイルをその内部を貫通し揺動自由に支持す
る導電性の心金とからなり、該除電コイルが記録材に接
触し、該心金が該除電コイルの両端で基板に固定され、
該基板が機器本体に連結されている除電器。The present invention is composed of a static elimination coil in which a conductive wire is formed in a coil shape and a conductive core wire that penetrates the static elimination coil and supports the static elimination coil in a freely swinging manner. The core is fixed to the substrate at both ends of the static elimination coil,
A static eliminator in which the substrate is connected to the device body.
除電コイルは、通常は各巻線毎に記録材に点接触す
る。記録材が撓んでいる場合、除電コイルはコイルの有
する弾性によって記録材の撓み形状に倣って弾力的に変
形し、接点における記録材との接触応力は一定である。The static elimination coil normally makes point contact with the recording material for each winding. When the recording material is bent, the static elimination coil elastically deforms following the bending shape of the recording material due to the elasticity of the coil, and the contact stress at the contact with the recording material is constant.
記録材に帯電した静電気は除電コイル及び心金を介し
て機外へ逃がされる。The static electricity charged on the recording material is released to the outside of the machine through the static eliminating coil and the cored bar.
以下、本考案の実施例を図面に従って具体的に説明す
る。Hereinafter, embodiments of the present invention will be specifically described with reference to the drawings.
第１図は本考案の除電器１を、図に省略した機器本体
の一部Ａに取り付けた状態の正面図、第２図はその断面
図を示すものである。FIG. 1 is a front view showing a state in which the static eliminator 1 of the present invention is attached to a part A of a device body (not shown), and FIG. 2 is a sectional view thereof.
図において、２は記録材Ｓに接触してその記録材Ｓに

て側面円形状に形成したものである。但し、コイル形状
は、円形に限定されるものではなく、楕円形・長円形・
三角形四角形またはそれ以上の多角形状等任意である。In the figure, reference numeral 2 denotes a coil for removing static electricity charged on the recording material S by contacting the recording material S, which is formed in a side surface circular shape using a conductive wire. However, the coil shape is not limited to a circular shape, but an elliptical shape, an oval shape,
Any shape such as triangular quadrangle or polygonal shape of more than that is possible.

スである。８は記録材Ｓの通路を形成するガイド板であ
る。Reference numeral 3 is a mandrel that supports the above-mentioned static elimination coil 2 so that it can swing freely within the range of its inner diameter. Both ends 2a and 2a of the static elimination coil 2 are supported by a mandrel 3
The coil 2 and the mandrel 3 are energized by fixing them to each other, but it is possible to energize them with a flexible conductor without fixing them.
Reference numeral 4 is a conductive substrate, 5 is a mounting portion of the cored bar 3 in which both ends of the substrate 4 are bent, 6 is a mounting hole for the device body, and 7 is a mounting screw. Reference numeral 8 is a guide plate forming a passage for the recording material S.
上記の構成により、記録材Ｓ、除電コイル２、心金
３、基板４、機器本体の順に静電気を通して機外へ逃が
すことができる。With the above structure, the recording material S, the static elimination coil 2, the mandrel 3, the substrate 4, and the device body can be discharged to the outside of the machine through static electricity in this order.
第３図は本考案の除電器１の一部を拡大した正面図を
示す。図に示すように記録材Ｓが波状に撓んでいる場
合、除電コイル２は記録材Ｓにその凹凸に倣って変形
し、その接点の荷重は変化がない。接点の間隔は除電コ
イル２のピッチを変えることにより自由に設計できる。FIG. 3 shows an enlarged front view of a part of the static eliminator 1 of the present invention. As shown in the figure, when the recording material S is bent in a wave shape, the static elimination coil 2 is deformed along the unevenness of the recording material S, and the load at the contact point remains unchanged. The distance between the contacts can be freely designed by changing the pitch of the static elimination coil 2.
なお、記録材Ｓとしては、紙・プラスチックフィルム
等がある。The recording material S may be paper, plastic film, or the like.
本考案の除電器は、上記のように構成したから、記録
材と除電コイルとの接触抵抗は小さく、しかも耐久性が
よい。また、記録材の撓みにかかわらず、除電コイルを
記録材に平均して接触させることができるので、除電効
果を向上させる。Since the static eliminator of the present invention is configured as described above, the contact resistance between the recording material and the static eliminator coil is small and the durability is good. Further, regardless of the bending of the recording material, the static elimination coil can be brought into contact with the recording material on average, thus improving the static elimination effect.
さらに、従来の除電器に比較して、本考案の除電器は
簡単に構成できるので安価に製作できる等の効果があ
る。Further, as compared with the conventional static eliminator, the static eliminator of the present invention has an effect that it can be manufactured at low cost because it can be easily configured.
