Abstract
A noncontact scanner operating under microcomputer control provides on-line bar code verification. Synchronized or free-scanning operation of the scanner is controlled by the microcomputer responsive to user inputs provided through an input keyboard. Manual functions selection using the keyboard and output display using multi-function LEDs and LCD display for communication to the user, provides direct input and output from the microcomputer and a bidirectional communications interface allows data and instruction exchange between the microcomputer and a host processor for data designation, analysis and record keeping activities. A plurality of control outputs from the controller allows real time control of the process or system being monitored.
Claims12
An on-line bar code verification system comprising:
- a single scanner having a control input for initiating a scan and a data output for multiple bar codes within a single scan line;
- a controller providing the control input to the scanner and having
- a means for sensing an external synchronization signal;
- a means for inputting a selection of a predetermined verification requirement for multiple bar codes within a single scan line;
- a means for directing output of a signal to the control input of the scanner;
- a means for receiving scanned data from said multiple bar codes within a single scan line, said receiving means connected to said scanner data output;
- a comparison means connected to the receiving means and responsive to said selection for comparing said scanned data for each of said multiple bar codes to said predetermined verification requirement;
- said directing means, receiving means and comparison means operable in a first mode responsive to said sensing means for synchronized scanning and in a second mode for continuous scanning;
- and,
- at least one signal output means responsive to said comparison means for generating a control signal output upon failure of a verification from any of said multiple bar codes.
