Image Scanner

We just learned about the Computer Printer.

Another part of a computer is an Image Scanner.

If you have a book, you might want to have a copy of some pages from the book on your computer.
A scanner is a machine where you can put a piece of paper or book on it, and then it will take a picture of the paper and put it onto your computer.

Some types of scanners are called flat bed scanners, because you put your paper or book flat on top of it.
Other types of scanners take a piece of paper, suck it in and then spit it back out after scanning.

Some fancy scanners have programs called "Optical Character Recognition" or OCR, which is a way to look at the book and actually read the words and letters instead of just making it a picture.
