置。 A paper feed roller that feeds paper from the paper feed cassette, a friction pad that is in pressure contact with the paper feed roller to prevent two or more sheets of paper from being sent out at the same time, and a paper feed roller that feeds paper in conjunction with the removal operation of the paper feed cassette. In a paper feed device equipped with a paper feed roller reversing mechanism that rotates the paper roller in the opposite direction to the paper feeding direction, the friction pad is rotated in the forward direction of the paper feed roller in conjunction with the removal operation of the paper feed cassette. What is claimed is: 1. A paper feeding device comprising: a friction pad rotating mechanism that moves a friction pad away from a paper feeding roller by moving the pad and presses it against the paper feeding roller in conjunction with the mounting operation of a paper feeding cassette;
