とする給紙分離装置。[Claim for Utility Model Registration] A paper feed separation means for separating sheets of paper stacked and held in a paper storage unit one by one and sending them to an image processing unit, which comprises a paper feed roller that rotates in a fixed direction, and a paper feed roller that rotates in a fixed direction; It has a friction pad in contact with the peripheral surface of the paper roller, the coefficient of friction between the peripheral surface of the paper feed roller and the paper is μ 1 , the coefficient of friction between the friction pad and the paper is μ 2 , When the coefficient of friction between the sheets is μ 3 , the physical properties of the various members described above are set so as to satisfy the relationship μ 1 > μ 2 > μ 3 . Both ends of the convex surface are aligned such that the center portion of the convex surface is aligned with and opposed to the center portion of the paper feed roller in the axial longitudinal direction (hereinafter referred to as the X direction), and the longitudinal direction of the convex surface is aligned in the X direction. The overall structure consists of a leaf spring attached to a stationary member, a pedestal supporting the friction pad, and a leg extending perpendicularly to the pedestal at the center of the pedestal. A friction pad holder configured in a T-shape, and a sliding groove formed in a stationary member and parallel to the X direction at a position opposite to the central portion of the paper feed roller. After aligning the longitudinal direction of the friction pad with the X direction, a part of the friction pad is fixed to the leaf spring at the center of the leaf spring, and the leg is fixed to the leaf spring. A paper feed separation device characterized in that it engages with a sliding groove.
