ABSTRACT:
An embodiment of a paper feed apparatus is provided with a pressure varying mechanism that varies a load pressure of a pickup roller to originals. The pressure varying mechanism has a rotating lever that switches the load pressure, a rotating arm that contacts and presses against a swinging arm of the pickup roller, and a biasing portion that biases the rotating arm to the swinging arm when the rotating arm contacts to the swinging arm. When continuously reading a wad of originals in which different-size originals are mixed, due to a user operating the rotating lever, the load pressure to the originals is increased by making the rotating arm contact to the swinging arm such that the swinging arm is pressed by the biasing portion.
