Abstract
Description
本発明は、蛇行防止ガイドが配設されているエンドレスベルトに関し、プリンター、複写機、ビデオプリンター等の電子写真記録装置などに有用である。 The present invention relates to an endless belt provided with a meandering prevention guide, and is useful for an electrophotographic recording apparatus such as a printer, a copying machine, and a video printer.
従来より、電子写真記録装置等の中間転写装置、転写装置、搬送装置等には、エンドレスベルトが使用されている。当該エンドレスベルトは、例えば、図４に示すように、複写機の中間転写装置の中間転写ベルト６として用いられ、下記のプロセスにて中間転写が行われる。即ち、感光ドラム１は帯電器３で均一に帯電され、露光器２により画像に対応した静電潜像が作られ、これが現像器５で現像され、トナーによるトナー像が形成される。トナー像は静電転写器１０により、中間転写ベルト６に転写され、転写されたトナー像は、押圧ローラ１２により記録紙１１に再び転写される。その際、中間転写ベルト６は、その内面に接する複数のローラ７、８、９により支持されるが、高精度に駆動しなければ、エンドレスベルトが蛇行し易く、露光位置や転写位置がずれるため画像ムラや画像ずれが発生し易い。 Conventionally, endless belts are used in intermediate transfer devices such as electrophotographic recording devices, transfer devices, and transport devices. For example, as shown in FIG. 4, the endless belt is used as an intermediate transfer belt 6 of an intermediate transfer device of a copying machine, and intermediate transfer is performed by the following process. That is, the photosensitive drum 1 is uniformly charged by the charger 3, and an electrostatic latent image corresponding to the image is formed by the exposure device 2, and this is developed by the developing device 5 to form a toner image with toner. The toner image is transferred to the intermediate transfer belt 6 by the electrostatic transfer device 10, and the transferred toner image is transferred again to the recording paper 11 by the pressing roller 12. At this time, the intermediate transfer belt 6 is supported by a plurality of rollers 7, 8, and 9 that are in contact with the inner surface of the intermediate transfer belt 6. Image unevenness and image misalignment are likely to occur.
そこで、蛇行防止用のガイドをベルトの端部に接着剤で貼り付けて、エンドレスベルトの蛇行を抑制する技術が公知である（特許文献１、特許文献２参照）。また、ガイドの磨耗性を改善した技術が公知である（特許文献３参照）。また、ガイドの剥離性を改善した技術が公知である（特許文献４参照）。また、エンドレスベルトの端部破壊を防止するために、エンドレスベルトとガイドの間に介在するように補強テープを設けること、さらに、ベルトの外周面にも同様に補強テープを設けることが記載されている（特許文献５）。 Therefore, a technique for suppressing meandering of an endless belt by attaching a meandering prevention guide to an end portion of the belt with an adhesive is known (see Patent Documents 1 and 2). Moreover, the technique which improved the abrasion property of a guide is well-known (refer patent document 3). Moreover, the technique which improved the peelability of a guide is well-known (refer patent document 4). In addition, it is described that a reinforcing tape is provided so as to be interposed between the endless belt and the guide in order to prevent the endless belt from being broken, and that a reinforcing tape is similarly provided on the outer peripheral surface of the belt. (Patent Document 5).
近年の装置の処理スピードの高速化・高画質化の傾向から、上記の特許文献１〜５の蛇行防止ガイドを貼り付けたエンドレスベルトにおいても、蛇行が生じ、ガイド溝からロール部に蛇行防止ガイドが乗り上げるという問題が生じていた。 In recent years, due to the trend toward higher processing speed and higher image quality of the apparatus, meandering also occurs in the endless belts to which the meandering prevention guides of Patent Documents 1 to 5 are pasted, and the meandering prevention guide from the guide groove to the roll portion. There was a problem of getting on.
本発明者は、上記の問題に鑑みて、種々検討を行った結果、本発明に至ったものである。すなわち、本発明の目的は、プリンター装置等の処理スピードの高速化・高画質化に対応すべく、蛇行防止ガイド付エンドレスベルトの蛇行防止ガイド部がロール部に乗り上げることを防止することができる蛇行防止ガイド付エンドレスベルトを提供することにある。 As a result of various studies in view of the above problems, the present inventor has arrived at the present invention. That is, an object of the present invention is to meander to prevent the meandering prevention guide portion of the endless belt with the meandering prevention guide from riding on the roll portion in order to cope with higher processing speed and higher image quality of a printer device or the like. It is to provide an endless belt with a prevention guide.
本発明は、蛇行防止ガイドが設けられた樹脂製のエンドレスベルトであって、
前記蛇行防止ガイドとエンドレスベルトの間に補強材を介在させ、または、蛇行防止ガイドが設けられたエンドレスベルト面と反対側の面に補強材を設け、
前記補強材の幅が、前記蛇行防止ガイドの幅よりも０．５ｍｍ〜２ｍｍ大きく、かつ、
補強材の幅方向の端部が、蛇行防止ガイドの幅方向の端部よりエンドレスベルト中央側に０．５ｍｍ〜２ｍｍずれて設けるように構成したことを特徴とする。
The present invention is a resin endless belt provided with a meandering prevention guide,
A reinforcing material is interposed between the meandering prevention guide and the endless belt, or a reinforcing material is provided on the surface opposite to the endless belt surface on which the meandering prevention guide is provided,
The width of the reinforcing material is 0.5 mm to 2 mm larger than the width of the meandering prevention guide, and
The end of the reinforcing member in the width direction is provided so as to be shifted from the end of the meandering prevention guide in the width direction by 0.5 mm to 2 mm toward the center of the endless belt.
この構成によれば、補強材によって、ベルトと蛇行防止ガイドの設置付近が補強され、その付近の変形が抑制されるため、蛇行が生じにくくなり、蛇行防止ガイド部がロール部に乗り上げることを防止できる。よって、プリンター等に用いられる場合、印字不良等が生じることがない。 According to this configuration, the reinforcing material reinforces the vicinity of the belt and the meandering prevention guide, and the deformation in the vicinity thereof is suppressed, so that meandering is less likely to occur and the meandering prevention guide part is prevented from riding on the roll part. it can. Therefore, when used in a printer or the like, printing defects do not occur.
また、本発明において、補強材の厚みが０．０５ｍｍ〜０．１ｍｍであることが好ましい。厚みを０．０５ｍｍ〜０．１ｍｍの範囲にすることで、駆動ロールやガイドロールへの追随性を損なうことなく、紙送りの障害もないので好ましい。０．０５ｍｍ未満では、補強力が十分でなく、０．１ｍｍを超えると、駆動ロールやガイドロールへの追随性が悪化したり、紙送りへの障害になる可能性が高くなるので好ましくない。 Moreover, in this invention, it is preferable that the thickness of a reinforcing material is 0.05 mm-0.1 mm. It is preferable to make the thickness in the range of 0.05 mm to 0.1 mm because the followability to the drive roll and the guide roll is not impaired, and there is no obstacle in paper feeding. If the thickness is less than 0.05 mm, the reinforcing force is not sufficient, and if it exceeds 0.1 mm, the followability to the drive roll or guide roll is deteriorated or the possibility of becoming an obstacle to paper feeding becomes high.
以下、本発明の実施の形態について説明する。本発明のエンドレスベルトは、例えば、電子写真式複写機、レーザープリンター等における感光装置、中間転写装置、転写分離装置、搬送装置、帯電装置、現像装置等に使用される。従って、これらの用途、機能に応じて、ベルトの材質、形状、大きさ等が適宜設定される。 Embodiments of the present invention will be described below.

The width and length of the meandering prevention guide are appropriately set according to the shape and size of the endless belt. When the cross-sectional shape of the meandering prevention guide is rectangular, its thickness (corresponding to the height as a guide) is preferably about 0.05 mm to 3 mm from the viewpoint of the meandering prevention effect and durability.
蛇行防止ガイド部材とベルト部材を貼り付けるための粘着剤（または接着剤）は、アクリル系、シリコン系、ゴム系等が挙げられ、蛇行防止ガイド部材とベルト部材の材質によって適宜選択される。粘着剤（または接着剤）は、基材を有して構成されていてもよい。 Examples of the pressure-sensitive adhesive (or adhesive) for attaching the meandering prevention guide member and the belt member include acrylic, silicon, rubber, etc., and are appropriately selected depending on the materials of the meandering prevention guide member and the belt member. The pressure-sensitive adhesive (or adhesive) may have a base material.
蛇行防止ガイドは、蛇行防止効果、裂け防止ための補強効果の点から、エンドレスベルトの両端部、あるいは片端部に設けられる。蛇行防止ガイドは、エンドレスベルトの内面全周にわたり粘着層（または接着層）を介して貼り合わされる。エンドレスベルトと蛇行防止ガイドを接着または粘着する方法は、公知の技術が適用でき、ここでの詳細な説明は省略する。本発明においては、エンドレスベルトと蛇行防止ガイドの間に後述する補強材を介在させることがある。 The meandering prevention guide is provided at both ends or one end of the endless belt from the viewpoint of the meandering prevention effect and the reinforcing effect for preventing tearing. The meandering prevention guide is bonded to the entire inner circumference of the endless belt via an adhesive layer (or adhesive layer). A known technique can be applied to the method of adhering or sticking the endless belt and the meandering prevention guide, and detailed description thereof is omitted here. In the present invention, a reinforcing material to be described later may be interposed between the endless belt and the meandering prevention guide.
補強材は、樹脂性フィルムと粘着層（または接着層）からなるテープ部材が好ましい。テープ部材の樹脂性フィルムの材質は、具体的にポリエステル系樹脂、ポリプロピレン系樹脂、ポリアミド系樹脂、ポリイミド系樹脂等が例示され、補強効果のある樹脂であれば、特に制限はない。但し、エンドレスベルトに貼り付けるためには補強材にある程度の硬さが必要であり、伸び性の大きいようなテープ部材は好ましくなく、例えば、ポリエステル系テープ部材が好ましい。テープ部材の片面（あるいは両面）には粘着層（または接着層）が設けられて、この粘着層（または接着層）を構成する粘着剤（または接着剤）は、特に制限されないが、例えば、アクリル系、シリコン系、ゴム系等が挙げられる。粘着層（または接着層）の厚みは、特に制限されないが、その機能が発揮される量が確保されていればよく、例えば、５〜１００μｍが望ましい。 The reinforcing material is preferably a tape member composed of a resinous film and an adhesive layer (or adhesive layer). Specific examples of the material of the resin film of the tape member include polyester resins, polypropylene resins, polyamide resins, polyimide resins, and the like, and there is no particular limitation as long as the resin has a reinforcing effect. However, a certain degree of hardness is required for the reinforcing material to be attached to the endless belt, and a tape member having high extensibility is not preferable. For example, a polyester tape member is preferable. An adhesive layer (or adhesive layer) is provided on one side (or both sides) of the tape member, and the adhesive (or adhesive) constituting the adhesive layer (or adhesive layer) is not particularly limited.

補強材の幅サイズは、蛇行防止ガイドの幅よりも０．５ｍｍ〜２ｍｍの範囲で大きく設定される。蛇行防止ガイドの幅サイズは、用途に応じて設定され、また、ロールの幅も設定されることにより、補強材のサイズもそれらに応じて設定される。０．５ｍｍ未満であると、厚みにもよるが補強力の観点から好ましくなく、２ｍｍを超える場合、ロールの平滑性、他の部材への悪影響から好ましくない。また、補強材の厚みは、０．０５ｍｍ〜０．１ｍｍの範囲に設定される。 The width size of the reinforcing material is set larger in the range of 0.5 mm to 2 mm than the width of the meandering prevention guide. The width of the meandering prevention guide is set according to the application, and the width of the roll is also set, so that the size of the reinforcing material is also set accordingly. If it is less than 0.5 mm, although it depends on the thickness, it is not preferable from the viewpoint of reinforcing force, and if it exceeds 2 mm, it is not preferable from the adverse effects on the smoothness of the roll and other members. The thickness of the reinforcing material is set in the range of 0.05 mm to 0.1 mm.
補強材は、エンドレスベルトと蛇行防止ガイドの間に介在するように設けられる場合がある。あるいは、エンドレスベルトの端部の内面全周に蛇行防止ガイドを設け、そのエンドレスベルトの端部の外周に補強材を設ける場合がある。また、補強材を、それら内周側と外周側の両方に設ける場合もある。また、図１に示すように、補強材は、その幅方向の端部が、蛇行防止ガイドの幅方向の端部よりエンドレスベルト中央側に０．５ｍｍ〜２ｍｍずれて設けられる。この場合、補強材の一方の端部と蛇行防止ガイドの一方の端部との位置を合わせ、その他方の端部は、蛇行防止ガイドの他方の端部よりもベルト中央側に、ずれるように貼付されることが好ましい。 The reinforcing material may be provided so as to be interposed between the endless belt and the meandering prevention guide.
