ABSTRACT:
A paper feeder system inclusive of a paper feed table for placing paper thereon, a transport roller, a first shaft for supporting the transport roller thereon, feed rollers, a first arm pivotably supported by the first shaft and extending toward the feed table, a delivery roller mounted on the first arm for delivering the paper from the feed table to the transport roller. A second arm pivotably supported between the delivery roller and the transport roller, and a shutter is attached to the second arm for preventing delivery of the paper to the transport roller. A first cam and a first cam shift therefor are provided for pivotally moving the first arm to thereby shift the delivery roller to an operative position, and a second cam and a second cam shaft therefor for pivotally moving the second arm to thereby shift the shutter to an operative position when the first arm is not pivotally moved, the first cam shaft and the second cam shaft being combined together in the form of a single rotary shaft.
