Abstract

An apparatus to switch a paper feed direction for an image forming device includes a paper guide part disposed across a paper feed path to move from an initial position to a paper passing position or a paper jam removing position by a force generated by passing of the paper, or external power; a supporting part to rotatably fix the paper guide part to a frame of the office machine; an elastic restoring part to restore the paper guide part from the paper jam removing position to the paper passing position; and a restoring force blocking part to block a force of the elastic restoring part from acting on the paper guide part until the paper guide part fixed to the supporting part rotates beyond the paper passing position. The apparatus blocks a force of the elastic restoring part from acting on the paper guide part until the paper guide part is rotated beyond the paper passing position, thereby reducing resistance against the paper and consequently preventing the paper from being blocked due to curling and jamming.
