Abstract
Automatic paper feeder includes a feed roller, and a paper-separating member in contact with the feed roller. A push member serves to press the paper-separating member against the feed roller. A spring serves to exert a pressing force on the push member. A mechanism serves to adjust the pressing force of the spring which is exerted on the push member. The spring-force adjusting mechanism includes a swingable adjustment plate connected to the spring, a cam, and a movable adjustment member connected to the adjustment plate via the cam. The adjustment member has a knob. At least a part of the knob is exposed to be easily accessed. The pressing force of the spring which is exerted on the push member is varied in accordance with a position of the knob.
