Claims Analysis
Total Claims: 9
Claim 1
Independent Claim
124 words
An automatic sheet reversing apparatus having: a convey/reversing section for receiving a one-sided copied sheet and conveying the sheet forward through a plurality of conveyor belts, and thereafter reversing the sheet adn conveying it backward; a stacking/moving section, having a stopper brought into contact with a distal end of the reversed sheet, for storing the sheets sequentially reversed and conveyed and for moving the sheets forward to a predetermined position; and a feed section having a feed belt for sequentially feeding the sheets at the predetermined position, characterized in that said stopper in said stacking/moving section is located below said plurality of conveyor belts in said conveying/reversing section, and an upper portion of said stopper is located above lower surfaces of said conveyor belts.
Claim 2
Dependent Claim
