First Claim
Patent Images
1. A system for electro-optically reading indicia having parts of different light reflectivity, comprising:
- a housing;
a scanner supported by the housing, for scanning at least one of a light beam directed at an indicium to be read, and a field of view extending over the indicium, said scanner having a component energizable by DC voltage; and
an energy collector supported by the housing, for collecting energy radiated from a radiant energy source for supplying the DC voltage to power said scanner component.

Abstract
A radiant energy source, e.g., solar energy, is employed to power an electro-optical reader, preferably by charging an on-board battery. A solar light collector is mounted on the reader in a location exposed to ambient light.
