Abstract
A manual sheet feeder including a pickup roller; a pickup arm; a sheet stopper; a rotation regulation member; a solenoid including a movable core having a straight line motion; a solenoid link rotatively coupled to the movable core; and a first spring to bias the pickup arm in a direction in which the pickup arm is rotated downward. At start of sheet feeding operation, the pickup arm is rotated by the first spring in a direction in which the pickup roller is moved downward in conjunction with rotation of the solenoid link caused by the straight line motion of the movable core in one direction, and the rotation regulation member is rotated in conjunction with the rotation of the solenoid link caused by the straight line motion of the movable core in the one direction to release regulation of rotation of the sheet stopper.
