特公昭５８−５１９６４号公報参照）。(Prior Art) Conventionally, in a copying machine equipped with an automatic paper transport device,
An endless belt is generally used as a means to convey paper to the platen section, and in order to ensure reliable conveyance, there is a device that uses static electricity to attract the paper to the endless belt and convey it. (For example, see Japanese Patent Publication No. 58-51964).

に接続されている。FIG. 4 is a sectional view of a conventionally used endless belt for electrostatic adsorption conveyance. This endless belt has an insulating layer 8
, on the composite laminate consisting of the reinforcing cloth 7 and the insulating layer 9,
It has a structure in which a plurality of patterned electrodes 4 and 5 formed in the shape of comb teeth are combined and formed to face each other, and a thermoplastic plastic layer 6 as a semiconductive material is provided thereon. . Note that the pattern electrode 4.5 is electrically connected to the power receiving terminal 10 exposed on the inner end surface of the endless belt.

Since the rolls are electrically connected to each other via the shafts 23 and 24, power is supplied by the metal portions of each roll coming into contact with the power receiving terminals exposed at the ends of the endless belt 25.
（発明が解決しようとする課題）
ところが、第４図に記載のような構造の無端状ベルトは
、構造が複雑であってその作成工程が増加し、コスト面

雑であり、またコスト的にも不利であった。(Problems to be Solved by the Invention) However, the endless belt having the structure shown in FIG. An increase in the thickness is also unavoidable. As a result, there was a problem in that it became difficult to stretch the roll onto a small diameter roll, and its uses were limited. Additionally, since it is made by laminating multiple layers of different materials, when used for a long time, each layer that makes up the laminate may peel off due to the bending motion during use, making it unusable. . Furthermore, since there is a thick laminated structure consisting of an insulating layer and reinforcing cloth under the pattern electrode, it is necessary to provide the power receiving terminal so that it penetrates the laminated structure and is exposed on the inner surface of the belt. It was also complicated and disadvantageous in terms of cost.

するために伸縮性のないことが要求される。In the paper feeding device as described above, in the case of a method of feeding paper using the friction coefficient of the belt, a relatively elastic belt such as a rubber belt is used as the belt, but as in the present invention, In addition, in the method of feeding paper using electrostatic adsorption force, a non-stretchable belt structure is required. In other words, on the back side of the endless belt, comb-tooth pattern electrodes for generating electrostatic adsorption force are formed by printing, etc., so the belt must not be elastic to prevent the pattern electrodes from breaking. is required.

。At the same time, the endless belt is required to be made of a material having semiconductive volume resistivity. Further, the endless belt is required to have flexibility so that it can be stretched and rotated on a roll having a diameter of about 20 mm. The endless belt of the present invention satisfies the above requirements, and has the functions of being non-stretchable, having durability and flexibility, and having semiconductivity separately. It is what I was given.
（実施例） 以下、本発明の実施例を図面によって説明する。(Example) Embodiments of the present invention will be described below with reference to the drawings.
第１図は、本発明の無端状ベルトの一例の断面図であり

櫛の歯状に互いに対向するように形成されている。The mesh material 3 is embedded in the semiconductive polymer material 2, and the semiconductive polymer material layer 2a exists on one side of the mesh material and the semiconductive polymer material layer 2a exists on the other side of the mesh material. The material layer 2b is integrally bonded within the network of the mesh material. On the back surface of the base belt l, electrodes 4 and 5 are formed so as to face each other in a comb-like shape.
上記の構成において、メツシュ材は、１本の繊維または

The roughness of the mesh material can be set as appropriate.

た、無端状ベルトの用紙と接触する面、すなわち表側は
、滑らかであるのが好ましく、例えば表面粗さＲａ≦２
ｍ＋以下であるのが好ましい。The semiconductive polymer material layers on both sides of the mesh material are made of a semiconductive polymer material with a volume resistivity of 108 to 1012 Ω0, such as polyurethane, NBR, silicone rubber 1,
Materials based on polyester, polypropylene, etc. are used, and flexible rubber-based materials are suitable. Further, the surface of the endless belt that comes into contact with the paper, that is, the front side, is preferably smooth, for example, the surface roughness Ra≦2
It is preferable that it is less than or equal to m+.
ベルト基材は、ロール状に巻かれた上記メツシュ材の両
面に、半導電性高分子物質を連続的に塗布し、乾燥する
ことによって形成することができる。The belt base material can be formed by continuously applying a semiconductive polymer substance to both sides of the mesh material wound into a roll and drying it.

Conductive polymers can be made by printing, such as screen printing. Further, the patterned electrodes can also be formed by processing a thin copper thread layer that has been pressure-bonded onto the base belt in advance by photo-etching or the like.

ところ、耐久性の点で同等問題がないことが確認された
。An endless belt made by forming a predetermined pattern of electrodes using a base material belt of 0.6 mm in thickness, which is made of polyester mesh material (thickness: OJmm) with polyurethane resin layers on both sides, was When the paper was stretched over a roll with a diameter of 22+mm in the paper feeding device shown in Figure 3 and operated 10,000 times, it was confirmed that there were no similar problems in terms of durability.
本発明の上記無端状ベルトにおいては、半導電性高分子

的に吸着されることになる。In the endless belt of the present invention, since the semiconductive polymer material layers 2a and 2b are electrically connected through the mesh of the mesh material 3, the patterned electrodes 4 and 5 formed on the back surface of the endless belt When a predetermined voltage is applied to the endless belt, current also flows to the front side of the endless belt. For example, if the pattern electrode 4 is on the high voltage side and the pattern electrode 5 is on the low voltage side,
The current tends to flow from the pattern electrode 4 to the pattern electrode 5 on the surface and inside of the endless belt, but also flows to the front side through the mesh material. Then, the paper placed on the front side of the endless belt is transferred to the semiconductive polymer material layer 2a on the front side.
When it comes into contact with , the current flows toward the paper, and a circuit is formed from the pattern electrode 4 through the semiconductive polymer material layers 2b and 2a, through the paper, and through the semiconductive polymer material layers 2a and 2b to the pattern electrode 5. The paper is electrostatically attracted to the endless belt.
なお、比較のために、メツシュ材の網目内で上下の半導
電性高分子物質層が一体的に接続していない場合、すな
わち上下の半導電性高分子物質層が絶縁された状態の場
合について、検討を行った。For comparison, the case where the upper and lower semiconductive polymer material layers are not integrally connected within the mesh of the mesh material, that is, the case where the upper and lower semiconductive polymer material layers are insulated. ,Study was carried out.
この場合、用紙を吸着させるためには、無端状ベルトの
厚み方向に見かけ上１０８〜１０１２Ω・備の体積抵抗
率をもたせる必要があるが、中間層（絶縁メツシュ材）
として高抵抗（１０１２Ω・０以上）のものが使用され
ている場合には、中間層の上下の半導電性高分子物質層
は１０８Ω・（至）以下、例えば、１Ｇ’Ω・（７）程
度のものにする必要がある。In this case, in order to attract the paper, it is necessary to make the endless belt have an apparent volume resistivity of 108 to 1012 Ω in the thickness direction, but the intermediate layer (insulating mesh material)
If a high-resistance material (more than 1012Ω・0) is used, the semiconductive polymer material layers above and below the intermediate layer should have a resistance of 108Ω・(to) or less, for example, about 1G′Ω・(7). It needs to be made into something.
ところが、この程度の体積抵抗率のものにすると、裏面
に形成されたパターン電極に漏れる電流が急卒に増大し
、無効になる電力が大きくなると共に、必要な高電圧が
印加できなくなる。However, when a material with a volume resistivity of this level is used, the current leaking to the pattern electrode formed on the back surface suddenly increases, and the amount of power that becomes ineffective increases, and the necessary high voltage cannot be applied.
例えば、本発明の無端状ベルトで、体積抵抗率１０１０
Ω・（７）の場合、２０℃で５５％Ｒ１１の環境下、軸
間１７３ ｃｍで駆動する場合、２ ＫＶでｌθμＡの
電流が流れるだけであり、２０ｍＷの電力で十分である
が、絶縁メツシュ材の両面に１０６Ω・（１）の半導電

００ｖでｌＯｍ Ａの電流が流れ、その時点でＩＷの電
力が必要であり、計算上Ｉ ＫＶではＩＯＷが必要とな
って、実用的に利用できない。For example, the endless belt of the present invention has a volume resistivity of 1010
In the case of Ω・(7), when driving in an environment of 55% R11 at 20°C with a distance of 173 cm between the shafts, only a current of lθμA flows at 2 KV, and a power of 20 mW is sufficient, but the insulating mesh In the case of an endless belt with semiconductive polymer material layers of 106 Ω (1) on both sides of the material, 1
At 00V, a current of 10mA flows, and at that point, IW power is required, and IOW is required for calculation at IKV, so it cannot be used practically.
また、中間層が高体積抵抗率を有するものであっても、
その厚さが薄ければ、トンネル効果によって見掛は上の
抵抗が低下することがわかっている。しかしながら、実
用的に使用できるようにするためには、中間層の厚さを
少なくとも０．０１ｍｍ以下にする必要があり、その場
合は中間層の作成が困難になると同時に、機械的強度の
確保も困難になるので、やはり実用的に利用できない。Moreover, even if the intermediate layer has a high volume resistivity,
It has been found that if the thickness is thin, the apparent resistance decreases due to the tunneling effect. However, in order to make it practically usable, the thickness of the intermediate layer must be at least 0.01 mm or less, which makes it difficult to create the intermediate layer and also makes it difficult to ensure mechanical strength. This would be difficult, so it cannot be used practically.
これに対して、本発明の無端状ベルトは、上記のような
問題点もない。On the other hand, the endless belt of the present invention does not have the above problems.

Moreover, it is non-stretchable and has good flexibility. In addition, since the semiconductive polymer material is embedded in the semiconductive polymer material so that it exists within the network of the mesh material, as is clear from the above comparison, it is possible to achieve high performance with low power consumption. It is possible to provide electrostatic adsorption force.
