Paper conveyor

A paper conveyor comprising conveyor rolls for conveying paper, drive means for driving and rotating the conveyor rolls, follower rolls which are pressed onto the conveyor rolls and hold paper to be conveyed between themselves and the conveyor rolls to thereby convey the paper in a predetermined direction, and a switch mechanism for switching the direction in which the paper is conveyed from one direction to another, the conveyor rolls, the follower rolls, the drive means and the switch mechanism being operatively connected to each other, wherein the switch mechanism is adapted to control the follower rolls so that the follower rolls can be rocked from one direction to another with their axis of rocking coinciding with an axis of the conveyor rolls, whereby enabling change of the direction in which paper is conveyed by means of the conveyor rolls and the follower rolls, further comprising a stand for mounting thereon a number of pieces of paper discharged from between the conveyor rolls and the follower rolls by conveyance, the stand being provided near the conveyor rolls and the follower rolls, and wherein the switch mechanism is adapted to control the position of the follower rolls with respect to the conveyor rolls so that the follower rolls can be rocked between a first position at which the paper is guided and conveyed in a direction toward the stand and a second position at which the paper is guided and conveyed in a direction opposite to the direction toward the stand so that coming our of rear edge of the paper guided and conveyed in the direction from between the conveyor rolls and the follower rolls can be facilitated, further comprising a base frame comprising first and second side frame plates, a rocking frame comprising first and second side plates, a driving shaft, a follower shaft, at least four bearing portions, first and second pulleys, a driving force transmission belt and a driving motor having a shaft, wherein the first side frame plate of the base frame and the first side plate of the rocking frame are arranged adjacent and parallel to each other, and the second side frame plate and the second side plate are arranged adjacent and parallel to each other, and wherein the conveyor rolls and the follower rolls are mounted on the driving shaft and the follower shaft, respectively, the driving shaft and the follower shaft each have a bearing portion on each end thereof and are supported by the first and second side plates of the rocking frame through the respective bearing portions so that the driving shaft and the follower shaft are parallel to and at a predetermined distance from each other, the follower rolls are capable of contacting the corresponding conveyor rolls during conveyance operation, the driving shaft is also supported by the first and second side frame plates of the base frame through the respective bearing portions, the driving motor is attached to the first side frame plate, with the shaft of the driving motor extending through the first side plate, the first pulley is fixed to one end of the driving shaft which is supported by the first side frame plate and by the first side plate of the rocking frame and the second pulley is fixed to one end of the shaft of the driving motor, and the two pulleys are operatively connected through the driving force transmission belt.
