DEFINITION

Classification: 341/1

DIGITAL PATTERN READING TYPE CONVERTER:

(under the class definition) Subject matter having a spatial variation of a parameter on an object to form a digital pattern carrier (e.g., movable code disk), and a pattern reading device providing a digital output.

(1) Note. Data conversion combined with structural detail of another art device is classifiable with the art device.

(2) Note. A record reader reads a selected one of plural recorded patterns, while a digital pattern reader can only read one pattern.
