Abstract

PURPOSE: To prevent erroneous paper feeding by providing a paper feeding board with an inclined angle through which a paper drops owing to its own weight, and by positioning the feeding board in such a way that the extension of the board passes through the center of a paper feeding roller, and thereby enlarging the contact area between a bottom part and the paper feeding roller.
CONSTITUTION: A paper feeding board 14 is set at an inclined angles β at which each paper starts dropping of itself due to its own weight, and placed in such a way that the extension B of the top surface of the board 14 passes through the center O of a paper feeding roller 11 or a little above of its. Thus, in paper feeding, the bottom part 13a is brought in contact with the paper feeding roller 11 in a large area, and bites into between the roller 11 and a separating roller 12. Since the friction coefficient between paper is made smaller than that of the roller 12, and the friction coefficient of the roller 12 to paper 13a, 13b... is selected to be smaller than that of the roller 11, the upper layered paper is returned by the roller 12 in the reverse direction of the feeding one.
