A multi-purpose scanner comprises a first body, a second body and a scanning module. The second body is disposed on the first body. A first passageway and a second passageway, which are for accommodating a first portion and a second portion of an angled document, and are disposed on a first plane and a second plane, respectively, are formed between the first body and the second body. An included angle is formed between the first plane and the second plane. The scanning module, disposed in the first body and/or the second body, performs an image scan operation on the first portion of the angled document in the first passageway to obtain an image signal.
