Abstract
Abstract A device for reading an encoded card is disclosed which includes a chamber for receiving a card encoded by a predetermined pattern of holes, a radiant energy source including a plurality of light source elements, and a radiant energy detector including a plurality of light-sensitive elements, both of which are synchronously moved by screws across opposite sides of the card to effect scanning and produce signals responsive to the particular code and provide information corresponding to the code. The screws are driven by motor-driven gears, and the direction of rotation is reversed by an axially movable rod with a cam surface that positively operates a motor reversing switch.

Claims Analysis
Total Claims: 10
Claim 1
Independent Claim
272 words
An encoded member reader comprising housing means including a pair of spaced sidewalls and adapted to receive between said walls at least one encoded member having a preselected pattern of areas providing indicia which transmit light energy to a greater extent than other areas of the encoded member, said walls having openings with at least portions thereof aligned with each other and with the indicia of an encoded member when disposed between said walls to be read, a pair of screw members mounted to said housing means on opposed sides of said walls for rotation and extending parallel to each other and to said walls, a source of radiant energy including first support means, and radiant energy emitting means connected to said first support means, said first support means being threadedly coupled to one of said screw members adjacent one of said wall openings for linear movement lengthwise of said one screw member in response to rotation of said one screw member, light responsive detector means including second support means, and radiant energy responsive means connected to said second support means, said second support means being threadedly coupled to the other of said screw members adjacent the other of said wall openings for linear movement lengthwise of said other screw member in response to rotation of said other screw member, drive means for rotating said screw members for simultaneously linearly moving said source of radiant energy and said detector means along said wall openings, said detector means receiving light energy passing through said indicia from said source, and means for producing signals responsive to the light energy received by said detector means.
Claim 2
Dependent Claim
272 words
An encoded member reader comprising housing means including a pair of spaced sidewalls and adapted to receive between said walls at least one encoded member having a preselected pattern of areas providing indicia which transmit light energy to a greater extent than other areas of the encoded member, said walls having openings with at least portions thereof aligned with each other and with the indicia of an encoded member when disposed between said walls to be read, a pair of screw members mounted to said housing means on opposed sides of said walls for rotation and extending parallel to each other and to said walls, a source of radiant energy including first support means, and radiant energy emitting means connected to said first support means, said first support means being threadedly coupled to one of said screw members adjacent one of said wall openings for linear movement lengthwise of said one screw member in response to rotation of said one screw member, light responsive detector means including second support means, and radiant energy responsive means connected to said second support means, said second support means being threadedly coupled to the other of said screw members adjacent the other of said wall openings for linear movement lengthwise of said other screw member in response to rotation of said other screw member, drive means for rotating said screw members for simultaneously linearly moving said source of radiant energy and said detector means along said wall openings, said detector means receiving light energy passing through said indicia from said source, and means for producing signals responsive to the light energy received by said detector means.
