PORTABLE SCANNER
First Claim
1. A portable scanner comprising:
- a digital camera module configured to capture digital images;
an optical lens optically coupled to the digital camera module;
a laser frame generator configured to project a visible laser frame having a two-dimensional interference pattern;
a portable scanner body housing at least the digital camera module and the optical lens;
a power supply coupled to the digital camera module and configured to supply power to the digital camera module;
a control interface on the portable scanner body comprising a power button and a shutter button, wherein the power button is configured to cause the portable scanner to turn on, and the shutter button is configured to control capturing of digital images;

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.
