ABSTRACT:
An automatic paper feed apparatus includes a receptacle for a paper roll, which receptacle comprises a curved floor and opposite side walls which slope outwardly from bottom to top. The floor is ribbed on it sinner surface to minimize frictional engagement of a leader from the paper roll with said floor. Within the receptacle, the paper roll rests upon a guide roll and a first feed roll which is capable of rotating the paper roll to feed a paper web from the roll. A guide chute is provided which guides movement of the paper web from the paper roll to an exit portion of the guide chute from where it may be introduced into a printer or other device. The guide chute is comprised of a portion of the floor of the receptacle and a movable upper element. The movable upper element is pivotally mounted at one end on the shaft associated with the first feed roll. A second feed roll is positioned between the ends of the guide chute to drive the paper web through the guide chute, and cooperates with pressure rolls mounted on the upper element of the guide chute. A motor is provided for driving the first and second feed rolls.
