In a copier, copy sheet handling apparatus is provided which includes a pair of feed rollers spaced apart from each other, and a copy sheet tray which extends substantially transversely through a plane which, in turn, extends midway between the feed rollers. Further, the copy sheet handling apparatus includes structure for swivelably supporting the tray in the aforesaid plane; and instrumentalities cooperative with the supporting structure for applying a resilient force to the tray substantially in the aforesaid plane to move the tray toward the feed rollers for disposition of a copy sheet into engagement with the feed rollers, whereby the force is substantially equally distributed between the feed rollers.

Copy sheet handling apparatus for a copier

In a copier including a flexible, endless web-type photoreceptor, and including suitable means for successively advancing the photoreceptor from a storage station and through several processing stations and back to the storage station, there is provided storing apparatus for supporting a major portion of the photoreceptor at the storage station in the form of a series of interconnected U-shaped loops. The supporting apparatus includes a plurality of loop supports, from which the photoreceptor loops are individually hung. In addition, the storing apparatus includes means for intermittently moving the loop supports and thus the photoreceptor loops in timed relation to advancement of the photoreceptor to and from the storage station.

Electrostatic copier including photoreceptor storing apparatus

A document feeder for an electrostatic copier of the type which includes instrumentalities for flash illuminating a document placed by an operator at the illuminating station of the copier. The document feeder includes an evacuatable enclosure having apertured upper and lower walls, and a flexible perforated belt endlessly looped about the enclosure. In addition, the document feeder includes instrumentalities for driving the belt in an endless path of travel including an upper belt run, wherein the belt perforations are disposed in air flow communication with the upper wall apertures, and a lower belt run, wherein the belt perforations are disposed in air flow communication with the lower wall apertures. When a document is delivered to the upper belt run, air drawn through the belt perforation holds the document in contact with the belt as the belt feeds the document to the lower belt run, where air drawn through the belt perforations holds the document in contact with the belt as the belt moves the document through the copier's illuminating station. Preferably, apparatus is provided for blocking movement of the document, but not the belt, through the illuminating station. During such time as the document is blocked, the moving belt slips relative to the blocked document.
