Image recording device
First Claim
1. Apparatus for scanning an image, the apparatus comprising:
- an image sensor;
a lens array disposed between the image sensor and the image to be scanned;
a light source for illuminating the image; and
a subassembly for incrementally scanning discrete portions of the image, wherein the scanning subassembly regulates energization of the light source in accordance with movement of the image sensor relative to the image, the scanning subassembly comprising;
a tracking element for indicating movement of the image sensor relative to the image, wherein the tracking element comprises;
a wheel configured for rolling contact on the image; and
an optical disk coupled to the wheel; and
a switch for switching the light source in accordance with the movement.

Abstract
A portable hand-held image recording device for generating and storing information representative of a two dimensional image includes a compact image scanning apparatus, a microprocessor, memory, and associated control software. The compact image scanning apparatus includes a light emitting diode array to provide a source of light, a focusing element to create a scan line on the image, a lens array to transmit light reflected off of the image, and an image sensor to convert the light reflected off of the image into electronic information. A scanning subassembly is provided to accurately track movement of the recording device across the image and to incrementally scan discrete portions of the image by controlling energization of the light emitting diode array.
