is there an upside-down scanner?

Question

you know that when you open the scanner, the crystal that scans the paper is down, and you have to put the paper looking down, so my question is, is there a scanner that haves the crystal thingy in the upper part so that when your going to scan something the paper is facing up?

They have scanners that can scan and print both the front and back side of what you have printed on the paper.
