This is a flatbed scanner - for prints.

I have another scanner with a base identical to the one for sale, but with a transparency lid mounted - it has a lamp inside, and can be used to scan negatives.
Why do I have two of these scanners? Because I had the same question as you, and bought the wrong one first.
