The type of scanner being described here is a flatbed scanner.

Flatbed scanners are very common and are designed primarily for scanning prints and text documents. They have a flat glass surface where you place the document or image to be scanned, and a lid that closes over the top. Most flatbed scanners indeed have some sort of guidance on the glass, such as a ruler or a strip, to help users position their documents correctly. They can digitize almost any type of image or document placed on the glass, making them versatile for general-purpose scanning tasks.
