Abstract
Abstract The directory includes a reader for a code punched card comprising a first portion including a first plurality of compartments having a given orientation. A single light emitting device is disposed in each of the first plurality of compartments and reflective material lines all the walls of each of the first plurality of compartments to diffuse light emitted by the light emitting device throughout the first plurality of compartments. A second portion of the automatic calling directory includes a second plurality of compartments having an orientation orthogonal to the said given orientation. A single light detecting device is diposed in each of the second plurality of compartments and reflective material lines all the walls of each of the second plurality of compartments to reflect the diffused light that pass through the punched holes in the card to the single light detecting device. Logic circuitry is coupled to each of the single light emitting devices for sequential activation thereof and is coupled to each of the single light detecting device to couple information read from the card to a transmitting line.

Claims Analysis
Total Claims: 27
Claim 1
Independent Claim
146 words
A reader for a code punched card comprising: a first portion including a first plurality of compartments having a given orientation, a single first means to emit light disposed in each of said first plurality of compartments, and second means completely lining all walls of each of said first plurality of compartments to diffuse light emitted by said single first means throughout an associated one of said first plurality of compartments; and a second portion including a second plurality of compartments having an orientation orthogonal to said given orientation, a single third means to detect light disposed in each of said second plurality of compartments, and fourth means completely lining all walls of each of said second plurality of compartments to reflect said diffused light passing through said card to said single third means in all of said plurality of second compartments receiving said diffused light.
