Aided design of Paper Tray

Design a prototype of papers trays, you can use any software to design it (aided design). A tray will contain a lot of papers, design a mechanism to pull a paper from a tray (like a printer) but without bending a paper and it must not touch on top of a paper via roll part. You will have to think of mechanism to do this. I will explain more information via private message and let me know if you have any questions.
