What kind of projector do I need to present a printed piece of paper or a page from a book?

3d scanner using projector image

toomuchhom

I'm looking for something similar to an overhead projector, but one that doesn't use transparencies. It's also similar to an opaque projector, but not one that only projects areas up to 6 x 6 inches! I need to show the whole 8.5x11 page (or at least most of it). I would also like something that shows 3D objects (like a text book or other object). My other requirement is that it works WITHOUT a computer or mounted projector (those that hook up to computers/TVs to enlarge). I need to use it just like those overhead projectors in classrooms years ago (and still today!)
Actually - I think it's a "document camera" - but I just need one that projects on its own without a TV screen or multimedia projector. Thanks

Answer
What you need is called an opaque projector if you insist on going low tech. I don't know if they are even made anymore.

A much better way is to just scan the pages and then transfer those images to PowerPoint and then display with a computer projector. Very easy if you have these basic items - scanner - computer - projector. I scan and display images this way all the time.

what are the complete list of input/output devices?? i need 25 each?

Answer
Your criteria was vague so some of these devices are in by technicalities.
input:
1. mouse
2. keyboard
3. camera
4. Scanner
5. game pad
6. drawing tablet (wacom) artist use
7. microphone (technically a headset with a mic falls under both)
8. finger print scanner
8. barcode scanner
9. light pen
10. midi keyboard musicians use
11. technically a laptop dolly ed to a computer or even another computer can remotely control a computer which would fall under both input/output
12. flash drives when reading
13. Scan disk when reading
14. external hard drive when reading
15. reading from dvd/cd/blu-ray disk
16. many used for medical procedures (ultrasound scanner)
output
1. speakers
2. printer
3. flash drives when writing
4. Scan disk cards when writing
5. external hard drive when writing
6. projector
7. monitor
8. tv
9. 3d printer
10. DVD/CD/Blu-RAY burned disk

Pretty much all I can think of.
