Paper feeding apparatus of image forming device

摘要

A paper feeding apparatus of an image forming device, includes: a driving source which outputs a driving force; a first roller disposed toward a first surface of a sheet of paper conveyed through a paper feeding path, and installed on a first shaft having a first roller gear to receive the driving force and thereby to rotate in a paper feeding direction to feed the sheet of paper; a second roller disposed toward a second surface of the sheet of paper to revolve in the paper feeding direction in contact with the first roller with a specified pressure, and installed on a second shaft having a second roller gear to receive the driving force and thereby to rotate in a direction opposite to the paper feeding direction; a multi sheet feed preventing part installed on the second shaft which selectively rotates the second roller in the direction opposite to the paper feeding direction to prevent a multi sheet feed; and gear trains to transmit or not transmit the driving force to the first and the second rollers.
