Patent ID: 7905648

Claim:
A device that enlarges text and images of an object being viewed to enable a low vision person to see said text and images, comprising: a hollow structure including a top housing and a bottom housing that are connected to one another, the bottom housing including a low friction surface to permit the device to slide on top of the object being viewed; a camera aperture formed in said bottom housing; a transparent light guide lens disposed in closing relation to said camera aperture so that all light entering said camera aperture must first pass through said light guide lens; a cavity formed in an exterior surface of said light guide lens; a printed circuit board with opposing ends, said printed circuit board disposed in overlying relation to an interior side of said light guide lens, said printed circuit board including a window that is in alignment with said light guide lens to allow light to pass therethrough; said light guide lens having a first mounting flange at a first end thereof, a second mounting flange at a second end thereof, and a raised section between said first and second mounting flanges; said cavity defined at its periphery by a plurality of sidewalls that are inclined at an angle of about one hundred thirty five degrees (135°) relative to said raised section to reflect light at an optimal angle, whereby said text and images are well-illuminated; a plurality of light-emitting diodes secured at the opposing ends of said printed circuit board and about said light guide lens, the light-emitting diodes being positioned above said mounting flanges and adjacent both said inclined sidewalls and said raised section, whereby light from the light emitting diodes must pass through and along said light guide lens to illuminate said text and images; a first undercut formed in a first end of said bottom housing adjacent a first edge of said camera aperture and a second undercut formed in a second end of said bottom housing adjacent a second edge of said camera aperture; said first undercut adapted to receive said first mounting flange, said first undercut defined by a first overhang, and said second undercut adapted to receive said second mounting flange, said second undercut defined by a second overhang; said first mounting flange having a length in excess of a depth of said first undercut so that a first space is created between said raised section of said light guide lens and said first overhang, said first space being larger than the light-emitting diodes; and said second mounting flange having a length in excess of a depth of said second undercut so that a second space is created between said raised section of said light guide lens and said second overhang.
