First Claim
Patent Images

1. optical mouse apparatus is characterized in that comprising:

  • One light source is in order to provide an illuminating bundle;

    One beam splitter is disposed on the bang path of this illuminating bundle, this illuminating bundle is divided into one first light beam and one second light beam;

    One Image Sensor is in order to this first light beam of sensing and this second light beam;

    AndOne lens are disposed at before this Image Sensor,One reflecting element is disposed on the bang path of this second light beam, with this second beam reflection to this reflecting surface,Wherein when this optical mouse apparatus is positioned over a reflecting surface, this first light beam does not see through this reflecting element, directly reflexed to this lens by this reflecting surface, and by this lens focus in this Image Sensor, this second light beam is not reflexed to this Image Sensor by this reflecting surface, and when optical mouse apparatus is positioned over a printing opacity object on this reflecting surface, this second light beam passes this printing opacity object Hou, reflected by this reflecting surface, again pass through this printing opacity object Hou to these lens, and by this lens focus in this Image Sensor, this first light beam is not reflexed to this Image Sensor by this reflecting surface.
