Abstract
In a recording sheet feeder, a recording sheet tray moving mechanism moves a recording sheet tray between an upper position, at which an uppermost recording sheet of a plurality of recording sheets loaded on the recording sheet tray contacts a feed roller, and a lower position, at which the uppermost recording sheet separates from the feed roller. A first eccentric cam and a second eccentric cam rotate to press down the recording sheet tray. A driving force switch member drives the recording sheet tray moving mechanism when a driver rotates in a first direction, and rotates a feed roller driving shaft mounted with the feed roller when the driver rotates in a second direction.
