Scan documents on the go with Windows 10 laptop?

Due to the current situation with Corona and the distance teaching, I have decided over the past few weeks to use my laptop (Lenovo Yoga) as a digital "notebook" for all subjects in classroom teaching. The only problem I now have is that I can't directly scan the sheets of paper that the teachers hand out (as is possible with an iPad and the like) and edit them on the laptop. Could someone have a solution for me? Are there perhaps small, handy cameras with which it is possible to scan documents on the go that is affordable for a student?

Yes a cell phone

Unfortunately, this is not allowed in school

You can take a laptop and a camera but not a cell phone?

tell your teacher to send you this by email

Does the laptop not have a camera?

Yes, unfortunately I don't understand the logic myself, but cell phones are against the "house rules". Unfortunately, my teachers will not want to put in the effort, but thank you anyway.

An indoor camera but I don't know if and how it can scan.

Yes hold the leaf in front of it no…

Unfortunately, the picture quality is too bad
