Abstract:
A medium position detection device including: a medium moving space (10) formed in which a plurality of media (30) can simultaneously move without overlapping in a predetermined direction; a light-guiding plate (11) which perpendicularly intersects the predetermined direction and defines the front of the medium moving space (10); a light source (20) disposed to emit light entering an end surface of the light-guiding plate (11); a reflecting section (13) formed in the light-guiding plate (11) so that the light having entered the light-guiding plate (11) is reflected by the reflecting section (13) and exits the light-guiding plate (11) through a back surface of the light-guiding plate (11); and detection means which detects the light from the light-guiding plate (11).
