ABSTRACT:
In a feeding device, a first friction pad and a second friction pad are disposed on a circumferential surface of a pick roller so that a first contact area and a second contact area overlap each other. Thus, to a conveyance-target medium, which is either one of a conveyed medium and a separation-target medium, pressing forces are successively applied by the first friction pad or the second friction pad over the first contact area to the second contact area. Therefore, the conveyance-target medium, which is either one of the conveyed medium and the separation-target medium, successively receives a separation force in a total contact area wider than an area when receiving a separation force only in either one of the first contact area and the second contact area. With this, the capability of separating the conveyed medium and the separation-target medium can be increased.
