GRAPHICAL DATA READING

**Definition:** This place covers:

Methods or arrangements for reading printed or written characters; for graph-reading or for converting the pattern of mechanical parameters into electrical signals; for printing of data in the shape of alphanumeric or other characters from a record carrier; for verifying the correctness of markings on a record carrier; for sensing record carriers; and for marking the record carrier in digital fashion.

Arrangements for producing a permanent visual presentation of the output data.

Column-detection devices.

Conveying record carriers from one station to another, e.g. from stack to punching mechanism.

Record carriers for use with machines and with at least a part designed to carry digital markings.

Information retrieval from punched cards designed for manual use or handling by machine, and apparatus for handling such cards, e.g. marking or correcting.

Arrangements for preparing the data output from a computer for printing, e.g. computer or network printers insofar as they are involved in outputting the result of a computation, like a document.

**Glossary:** - Record carrier: means a body, such as a cylinder, disc, card, tape, or wire, capable of permanently holding information, which can be read-off by a sensing element movable relative to the recorded information or by electrical contacting or non-contacting means - Data: is a synonym for information
