ABSTRACT:
An automatic paper feeding apparatus used in an electronic apparatus including a tray frame, a tray body, a paper-taking roller, at least a wiggling device and a frictional roller is provided. The tray body can move into and out from the tray frame. The paper-taking roller moves the top paper by rotating along a rotating direction. The wiggling device wiggles toward the paper-taking roller from an initial position. When the paper-taking roller moves the top paper, the frictional roller faces the paper-taking roller and contacts the top paper by the same frictional surface. When the tray body moves out the tray frame, the frictional roller rotates and causes the other frictional surface of the frictional roller to face the paper-taking roller substantially. When the tray body moves into the tray frame, the wiggling device wiggles toward the paper-taking roller from the initial position and wiggles back to the initial position.
