AS A RESULT OF REEXAMINATION, IT HAS BEEN DETERMINED THAT:
Claims 1-17 are cancelled.
1. A branched throat auto-feed paper shredder comprising:
a motor-driven shredding mechanism accessible by a branched throat;
a manual input slot leading to a first branch of said throat which feeds down to said shredding mechanism;
a first sensor which detects paper in the first branch and activates the shredding mechanism;
a second branch of said throat being curved or angled and leading to a slanted, input tray into which a stack of paper sheets to be shredded can be inserted;
an input roller disposed in the second branch so that when a stack of papers is inserted therein, ends of the papers rest against the input roller;
a linkage between the roller and a motor so that the roller rotates when the shredding mechanism is activated; and
a second sensor for detecting paper in the second branch and activating the shredding mechanism when paper is detected so that the roller rotates and pulls a top sheet of paper under the roller and pushes the top sheet into the second branch of the throat where said sheet of paper curves downward to interact with the shredding mechanism and is shredded.
