Abstract
A sheet feeder includes a delivery roller, a supply roller, a separating member, a driving source, a first drive transmission mechanism, a second drive transmission mechanism, and a controller. The first drive transmission mechanism transmits the rotary drive power in the first direction to the delivery roller in a first drive transmission time from the start of driving of the driving source. The second drive transmission mechanism transmits the rotary drive power in the first direction to the supply roller in a second drive transmission time from the start of driving of the driving source. The second drive transmission period of the second drive transmission mechanism is longer than the first drive transmission period of the first drive transmission mechanism. When the control starts driving the driving source, the supply roller starts to rotate in the first direction after the delivery roller starts to rotate in the first direction.
