摘要： A sheet feeder has a tray on which a sheet to be fed is to be placed. A lift plate is at a feeding end of the tray and has a first end at an upstream side in a feeding direction connected rotatably to the tray. The lift plate is displaceable between a feeding posture where a second end at a downstream side in the feeding direction is lifted up and a retracted posture where the second end is lower than in the feeding posture due to its own weight. A biasing member gives a biasing force to an elevating member in a direction to lift the lift plate to the feeding posture. A lowering mechanism gives a pressing force against the force of the biasing member to lower the lift plate to the retracted posture.
