Claims

[Claims for Utility Model Registration] (1) A paper feeding device that feeds paper one sheet at a time by coming into contact with the topmost sheet of paper loaded in a cassette, with a shape in which the radius gradually increases toward the opposite side of the rotation direction. a sheet-like feeding roller made of a sheet-like elastic member; and a guide plate that presses and guides the free end of the sheet-like feeding roller in the rotational axis direction in a rotating region of the sheet-like feeding roller that does not come into contact with the paper surface. A paper feeding device characterized by being provided. (2) In a paper feeding device that feeds paper one sheet at a time by coming into contact with the topmost paper loaded in a cassette, a sheet made of a sheet-like elastic member whose radius gradually increases toward the opposite side of the rotation direction. a leaf spring integrally formed inside the sheet-like elastic member of the sheet-like feed-out roller; a compression spring fixed in the radial direction from inside near the free end of the sheet-like feed-out roller; A paper feeding device characterized by being provided with.
