摘要： There is disclosed an improvement in a system for sensing information encoded on a duplicating original, using the information to control copy processing. A duplicating original is installed onto the surface of a cylinder revolving in the duplication process. The encoded information, in the form of indicia printed on the original, is sensed by an optical read head arranged to scan the revolving cylinder. Signals indicating the position of the revolving cylinder are used to determine when to scan for information. Finally, the information sensed, e.g., the copy quantity, is used to control the processes of the duplicating machine. The manner in which the encoded information is arranged conforms to the writing capabilities of a computer output printer, which is preferably also used to prepare the body of text material being duplicated, and the read head is arranged to sense the thus applied indicia and reproduce the information accurately, allowing wide latitude for correct placement of the information. Hand encoding by an operator is also easily performed.
