A friction sheet feeding machine is provided. The friction sheet feeding machine comprises a hopper configured to hold a stack of items. The friction sheet feeding machine also comprises a receiver configured to receive an item from the stack of items. The friction sheet feeding machine also comprises a separating mechanism configured to separate the item from the stack of items. The separating mechanism comprises a drive mechanism. The drive mechanism is configured to operate in a forward direction and a reverse direction. The friction sheet feeding machine also comprises a controller configured to generate signals to the drive mechanism to operate in the forward direction for a first period of time, and in the reverse direction for a second period of time.

A paper feed apparatus comprises a paper feed section, a separation section, a rotating body and a control device. The paper feed section feeds an image receiving medium that is placed. The separation section is arranged at a downstream side of the paper feed section in a conveyance direction of the image receiving medium. If a plurality of the image receiving media fed from the paper feed section is overlapped, the separation section separates the plurality of the image receiving media that is overlapped. The rotating body is arranged at the upstream side of the separation section in the conveyance direction of the image receiving medium. The rotating body is capable of contacting with the placed image receiving medium. The rotating body is rotatable. The control device carries out control to rotate the rotating body at least before an operation of the paper feed section.
