れぞれについて、摩擦係数×接触圧が等しくなる
ようにそれらのローラに接触している。 FIG. 1 shows a basic example of the paper dust adhesion prevention device of the present invention, in which a paper dust removal roller 3 contacts both paper feed rollers 1 and 2 at the same time, and each roller moves in the direction indicated by the arrow in the figure. rotate respectively. Copy paper 4 is fed by paper feed rollers 1 and 2 in the direction of the arrow. The paper dust removing roller 3 is in contact with each of the paper feed rollers 1 and 2 so that the coefficient of friction times the contact pressure is equal to each other.

ローラおよびベルトについて摩擦係数×接触圧=
一定となるように該接触圧が調整されている。 Specifically, when the paper feed rollers 1 and 2 have the same coefficient of friction, the paper dust removal roller 3 is brought into contact with each paper feed roller with the same pressure,
On the other hand, if the paper feed rollers 1 and 2 are made of materials with different coefficients of friction, the contact pressure of the paper dust removal roller against these paper feed rollers will be different, but for each roller and belt, the friction coefficient x contact pressure =
The contact pressure is adjusted to be constant.

速と異なる周速で回転するようになつている。 The rotational direction of the paper dust removing roller 3 is set in such a direction that its circumferential surface and the circumferential surfaces of the paper feed rollers 1 and 2 move in the same direction at their contact points. That is, in FIG. 1, paper feed rollers 1 and 2
rotates counterclockwise, while the paper dust removing roller 3
is designed to rotate clockwise. Furthermore, the paper dust removing roller 3 is configured to rotate at a peripheral speed different from that of the paper feed rollers 1 and 2.

8 and a paper feed belt 9 wound around a pair of pulleys 6 and 7, which work together with a paper sorting roller 10 and a pinch roller 11 to feed the paper 1
2 is fed one by one from left to right in the figure.
The circumferential velocities V 1 , V 2 and V 3 of the paper feed roller 5, paper feed belt 9 and paper feed roller 8 generally increase in order, for example, V 1 :V 2 :V 3 ≒1:2. :

The paper dust removing roller 13 is in contact with the paper feed roller 5 and the paper feed belt 9 such that the coefficient of friction multiplied by the contact pressure is equal to each other. A similar relationship holds true between the paper dust removal roller 14, the paper feed roller 8, and the paper feed belt 9.
