Abstract
The paper feeding apparatus includes a manual feed tray, a spindle, a rotation lever, a cam, an operation shaft, a projection portion, an operation arm, and a stopper. The paper feeding apparatus is able to switch to/from automatic and manual paper feeds for stable loading of paper on the paper loading board and manual paper feed. The manual feed tray is openable/closable by turning around the spindle. The rotation lever and the cam are fixed on the operation shaft. When the manual feed tray is opened, the projection portion pushes the rotation lever. When the manual feed tray is closed, the cam touches the backside of the operation arm and the stopper rises. When the manual feed tray is opened, the rotation lever is pushed by the projection portion and the cam rotates in the clockwise direction separating from the backside of the operation arm. The stopper, consequently, is lowered.
