うにしたことを特徴とする給紙装置。 A tray on which multiple sheets of paper are placed one on top of the other, a paper feed roller that feeds the paper placed on the tray one by one to the downstream side of the feeding path, and a paper feed roller that feeds the paper. A paper detection means outputs a predetermined detection signal when the paper reaches a predetermined position on the feeding path, and the paper detection means outputs a detection signal from when the paper feed roller starts feeding the paper until the paper detection means outputs the detection signal. A paper feeding device characterized in that the feeding performance of a paper feeding roller is detected based on the length of time.
