Abstract
A sheet detection device includes: a magnetic sensing element disposed on a sheet guide, wherein the sheet guide brings the magnetic sensing element to move to a first position or a second position; a first magnetic element disposed on a sheet tray corresponding to the first position; a second magnetic element disposed on the sheet tray corresponding to the second position and in spaced with the first magnetic element; a processing element electrically connected with the magnetic sensing element. When the magnetic sensing element outputs a first voltage signal, the processing element determines the sheet guide is located at the first position according to the first voltage signal. When the magnetic sensing element outputs a second voltage signal, the processing element determines the sheet guide is located at the second position according to the second voltage signal. The first voltage signal is different from the second voltage signal.
