  • Patent number: 8767269
    Abstract: A portable document scanner that records both image and voice information, comprises a digital camera module configured to capture document images, and a laser frame generator configured to project a visible beam of light forming a laser frame to indicate the corresponding field of view of the optical lens for framing a document to be captured. A light source generated by a laser diode is shaped by passing through a collimating optical element and a diffractive optical element which is configured to produce a visible laser frame for framing a document to be captured. The captured data is then stored in an internal memory of the scanner. A data connector is permanently attached to the scanner body, which is used to connect the scanner directly into a receptacle on an external device for accessing data.
