ABSTRACT:
A guide chute arrangement for an apparatus used to feed a computer form printout web to the original document platen of a copying machine which includes a pivotally mounted copyboard overlying the platen over and about which the web is fed, includes an upper chute assembly for guiding the web between the upper surface of the copyboard and a first supply tray and a lower chute assembly for guiding the web between the lower surface of the copyboard and a second supply tray. Each of the chute assemblies includes complementarily, predeterminedly shaped upper and lower walls forming channels therebetween. The lower walls of the chute assemblies are fixedly mounted. The upper wall of the upper chute assembly is mounted for pivotal movement on extension arms which permit the movement of the upper wall away from the lower wall for easy threading of the web thereinto. The upper wall of the lower chute assembly is pivotal about its lower end and includes pins at the upper end received in a predeterminedly shaped guide channel formed in the support frame of the copyboard so that upon pivoting the copyboard out of the position overlying the platen, the pins are moved through the channel pivoting the upper wall of the lower chute assembly about its lower end thereby to separate the upper wall from the lower wall for easy threading of the web.
