  • Apparatus for detecting objects in sheet form with light redirecting means
    Patent number: 5260564
    Abstract: An apparatus for detecting a sheet in a conveying path, comprising a light source and a light receiver on one side of the conveying path and a light-reflecting element in the form of a prism on the other side of the conveying path for reflecting for the light receiver a beam of light emitted by the light source, wherein the prism has a first reflecting surface opposite the light source, a second reflecting surface opposite the light receiver and a third reflecting surface which deflects, in the direction of the second reflecting surface, the beam of light reflected by the first reflecting surface, so that the apparatus is less sensitive to deviations of the position of the prism with respect to the light source and the light receiver.
