Abstract
Abstract A reading apparatus for a handicapped person includes a reader for optically reading character information from a recording medium and photoelectrically converting the character information so that it is displayed by a pin pattern on a display. When the operator detects a character area from the display result, an area of an object for character recognition is designated by an input unit and the execution of the character recognition is instructed. A processor recognizes the character read by the reader and displays the character so that it can be perceived in a tactile manner. Whether the result of the reading of the character is correct or not can be checked by tactile perception. The recognition result of the character recognized can also be converted into an audio output by an audio output unit.

Claims Analysis
Total Claims: 13
Claim 1
Independent Claim
120 words
A reading apparatus for an eyesight handicapped person, comprising: reading means for optically reading character information from a recording medium on which the character information has been recorded and for converting the read character information into an electrical signal; first converting means for converting the electrical signal from said reading means into information which can be perceived in a tactile manner; second converting means for converting the electrical signal from said reading means into coded information and, thereafter, for further converting the coded information into corresponding information which can be perceived in a tactile manner; and display means for displaying the information generated from said first and second converting means so that it can be perceived in a tactile manner.
Claim 2
Dependent Claim
120 words
A reading apparatus for an eyesight handicapped person, comprising: reading means for optically reading character information from a recording medium on which the character information has been recorded and for converting the read character information into an electrical signal; first converting means for converting the electrical signal from said reading means into information which can be perceived in a tactile manner; second converting means for converting the electrical signal from said reading means into coded information and, thereafter, for further converting the coded information into corresponding information which can be perceived in a tactile manner; and display means for displaying the information generated from said first and second converting means so that it can be perceived in a tactile manner.
Claim 3
Dependent Claim
45 words
An apparatus according to claim 1, wherein said reading means comprises independent first and second reading means, wherein said first converting means receives the electrical signal from said first reading means, and said second converting means receives the electrical signal from said second reading means.
Claim 4
Dependent Claim
43 words
