Description of the Related Art Paper feeding devices such as PPCs and facsimiles have conventionally taken measures to prevent double feeding so that two or more sheets of paper do not overlap each other. For example, as shown in FIG. 1, when a rubber plate 2 for preventing double feeding is provided opposite the paper feed roller 1 and two or more sheets of paper 3 are fed along the paper feed roller 1, The rubber plate 2 prevents the second and subsequent sheets of paper 3 from advancing (sorting pad method). Alternatively, as shown in FIG. 2, the paper feed roller 1 and the tension roller pair 4
．． A rubber roller 6 for preventing double feeding is provided opposite to the forward rotating roller 5 provided between the paper sheets 4a and 6, so that the rubber roller 6 prevents the excess paper 3 from being fed (reverse roller sorting method). .

る「鳴き」 （不快なきしみ音）が発生し、問題となっ
ている。Synthetic rubber materials such as ethylene rubber, Hypalon (chlorosulfonated polyethylene), ethylene-propylene rubber, and urethane materials such as polyurethane are used.
The frictional properties unique to the rubber-like elastic body (frictional force is a combination of 80% due to adhesion and 20% hysteresis loss due to deformation) prevents excessive progress of the 3. However, in materials having such friction characteristics, when the rubber and paper come into close contact with each other and separate, static frictional force and dynamic frictional force are generated alternately, and the difference between the two frictional forces is large, resulting in a stick-slip phenomenon. This vibration causes so-called "squeaks" (unpleasant squeaks), which has become a problem.
そこで、この「鳴き」の防止策として、ゴム中にコルク
粒子を混入させて紙とゴムとの密着性を弱め、静−動摩
擦力の差を少なくしてスティックスリップ現象の発生を
防止することが提案され一部で実用化されている（特公
昭６２−５６０６１号公報）。Therefore, as a measure to prevent this "squeal", it is possible to mix cork particles into the rubber to weaken the adhesion between the paper and the rubber, reduce the difference in static and kinetic friction, and prevent the stick-slip phenomenon from occurring. It has been proposed and put into practical use in some cases (Japanese Patent Publication No. 56061/1983).
しかしながら、上記コルク粒子の混入によってスティッ
クスリップ現象はある程度解消するものの、使用の継続
によりコルク粒子よりも軟質なゴムの表面が摩耗して、
第３図に示すように、ゴム部分８からコルク粒子７が突
出するようになる。However, although the stick-slip phenomenon is resolved to some extent by incorporating the cork particles, the surface of the rubber, which is softer than the cork particles, wears out with continued use.
As shown in FIG. 3, cork particles 7 come to protrude from the rubber portion 8.
このため、この突出部分に紙が引っ掛かって紙詰まり等
のトラブルが生じやすくなる。このように、コルク粒子
７の混入によっても、給紙に伴うトラブルを完全に解消
することができず、その解決が望まれていた。For this reason, troubles such as paper jams are likely to occur due to paper being caught in this protruding portion. As described above, even with the contamination of cork particles 7, it is not possible to completely eliminate the troubles associated with paper feeding, and a solution has been desired.
この発明は、このような事情に鑑みなされたもので、紙

できる重送防止用ゴム部材の提供をその目的とする。This invention was made in view of these circumstances, and is a double-feed prevention device that prevents the occurrence of "squeak" due to the close contact between paper and rubber, and maintains trouble-free and smooth paper feeding over a long period of time. Its purpose is to provide rubber members.

The structure is such that fine inorganic fillers are dispersed and contained at a ratio of 20 to 80% relative to the total amount.

．１〜５μｍに限定している。In other words, the rubber member for preventing double feeding in the paper feeding device of the present invention is a compound containing a fine inorganic filler at a predetermined ratio, and the presence of this fine inorganic filler prevents the rubber from adhering to the paper. This prevents "squealing" from occurring. Unlike things like cork, this inorganic filler can be made into fine particles, and even when made fine, the outer periphery of the particles is smooth and has the effect of reducing frictional force. It is effective in preventing the occurrence of Furthermore, when the rubber surface wears out due to long-term use, it falls off from the rubber surface accordingly, so unlike conventional cork particles, it does not protrude from the rubber surface and interfere with paper feeding. From this point of view, in the present invention, the particle size of the fine inorganic filler is reduced to 0.
．． It is limited to 1 to 5 μm.
つぎに、この発明の詳細な説明する。Next, this invention will be explained in detail.
この発明の給紙装置における重送防止用ゴム部材は、ゴ
ムマトリックス中に、所定の無機系充填材を所定割合だ
け分散含有させたものである。The rubber member for preventing double feeding in the paper feeding device of the present invention includes a rubber matrix containing a predetermined inorganic filler dispersed in a predetermined proportion.

ある。The rubber materials that make up the rubber matrix are as follows:
Although various rubber materials conventionally used for rubber members for preventing double feeding can be used, Hypalon is particularly suitable from the viewpoints of friction coefficient characteristics, abrasion resistance, weather resistance, etc.
また、上記無機系充填材としては、ハードフレ、炭酸カ
ルシウム、タルク等があげられ、単独で、もしくは２種
以上を併用することができる。Further, examples of the above-mentioned inorganic fillers include hard foam, calcium carbonate, talc, etc., and these can be used alone or in combination of two or more kinds.
ただし、これらの無機系充填材は、平均粒子径が０゜１

径が０．１μｍ未満ではゴムと紙との密着を阻害するこ
とが困難で「鳴き」の発生を防止することができない。However, these inorganic fillers have an average particle diameter of 0°1
It is necessary that the thickness is set to ~5 μm. If the average particle diameter is less than 0.1 μm, it is difficult to inhibit the adhesion between the rubber and the paper, and it is impossible to prevent the occurrence of “squeak”.

紙捌き性が悪くなり、重送が発生しやすくなるからであ
る。On the other hand, if the average particle diameter exceeds 5 μm, the abrasion resistance of the resulting rubber member decreases, making it impractical. The inorganic filler needs to be blended in a proportion of 20 to 80% by weight (hereinafter abbreviated as "%") based on the total amount of the rubber composition. The blending ratio of inorganic filler is 20
If it is less than %, it is difficult to prevent the adhesion between rubber and paper.
It is not possible to prevent the occurrence of "squeal". On the contrary, 80%
This is because, if it exceeds this value, the surface friction coefficient of the rubber member obtained will decrease, resulting in poor paper handling properties and double feeding is likely to occur.

効果は、長期の使用によっても薄れることがない。The rubber member of the present invention can be manufactured using the above rubber material and the inorganic filler (including the above additives as necessary), for example, in the following manner. That is, the rubber material and the inorganic filler are blended in a predetermined ratio and kneaded uniformly. Then, the desired rubber member can be obtained by three-dimensionally crosslinking the rubber portion by sulfur vulcanization, peroxide crosslinking, or the like. This rubber member may be formed into a plate shape and used as a rubber plate 2 for preventing double feeding as shown in Fig. 1, or a crosslinked rubber layer may be formed on the surface of the roll core metal using a mold. Accordingly, it may be used as a rubber row J cough for preventing double feeding as shown in FIG. 14 The paper feeding device incorporating the rubber plate for preventing double feeding or the rubber roller for preventing double feeding obtained in this way does not generate "squeak" when feeding paper, and
Further, troubles such as paper jams do not occur. This effect does not fade even with long-term use.

I understand.

The friction coefficient of this rubber roll was measured when it was not in use, and the friction coefficient was again measured when it was actually incorporated into a PPC and used to make 100,000 copies. In addition, the number of times the "squeak" occurred while copying these 100,000 sheets was counted, and the "squeak" occurrence rate was calculated. These results are also shown in Table 2 below.

ある。(See margin below) From the above results, it can be seen that "squeal" was effectively prevented in all of the implemented height measurements. Furthermore, it can be seen that the coefficient of friction has a preferable value both when unused and after 100,000 copies. On the other hand, comparative height measurements are all
This may cause "squealing" or the coefficient of friction is low, causing problems in paper handling.

（、良好な紙捌き効果を維持することができる。As described above, since the rubber member for preventing double feeding in the paper feeding device of the present invention contains a predetermined amount of fine inorganic filler dispersed therein, this inorganic filler prevents the rubber from adhering to the paper. This prevents "squealing" from occurring. Moreover, since this inorganic filler is finely divided, when the rubber surface wears out due to long-term use, it falls off from the rubber surface and protrudes from the rubber surface like conventional cork particles, making it difficult to feed paper. There's nothing that gets in the way. Therefore, even after long-term use, there is no problem with paper feeding (and a good paper sorting effect can be maintained).
