Pseudo Programmable Control Unit

This control system changes through a number of physical, mechanical or electrical states.

Character reader 10 reads data from a moving document 12 and transfers such data to processor 15. The latter, in the time interval between documents 12, must issue a command to select a pocket 14 for document 12 and to read the next successive read order for the next document. The pocket selection is based on an analysis of the data read from the document. The time available for doing an analysis can decrease. This is due to multiple readers being connected to the processor 15 with priorities which can result in the decision to select a given pocket 14 occurring subsequent to the physical movement of the document passed that pocket with resulting collection of the document in reject pocket 16.

For more instantaneous control, logical decision units 18, 20, 22, etc., are included in processor 15 to reflect the required control signal with the data input as received at that time. When the first data is read from the document, decision unit 18 is set to generate a control output to select a further decision unit 20, 22,
24.

Upon detection of the second data, logical unit 20, etc., in turn selects a further logical unit. Units 18, 20, 22, etc., thus continuously reflect the required decision for any previous input of data.

Terminal logical units 26, 28, and 30 generate a control output to reselect themselves until reader 10 indicates to processor...
