ることを特徴とする給紙装置。 a paper feed roller having a substantially cylindrical peripheral surface and a notch; a drive source for supplying rotational force to the paper feed roller; and a clutch means for controlling transmission of rotational force from the drive source to the paper feed roller; a paper layer that is biased in a direction close to the paper feed roller, and the rotation of the paper feed roller brings the peripheral surface portion into pressure contact with the paper layer to feed one sheet of paper from the paper layer. The apparatus includes a paper position detection means for detecting the position of the paper layer, and operates the drive source for a predetermined time when the power is turned on, and turns on the power according to the detection result of the paper position detection means within the predetermined time. A paper feeding device characterized in that the rotational position of the paper feeding roller at a certain time is determined.
