Abstract:
An apparatus for detecting front edge of a document and determining home position of an image scanning module has a detecting light source near an outlet end of a document feeding track and aligned with an image reader of the image scanning module. The detecting light source emits a detecting light to be received by the image reader. By detecting whether the detecting light is received by the image reader, the front edge of the document can be detected to activate the image scanning module. And it can also determine whether or not the image scanning module has arrived on a home position.
