  • It is another object of the present invention to provide a checkout method involving a checkout device which includes an integrated barcode reader, scale, and electronic article surveillance system.
    • BRIEF DESCRIPTION OF THE DRAWINGS
  • Additional benefits and advantages of the present invention will become apparent to those skilled in the art to which this invention relates from the subsequent description of the preferred embodiments and the appended claims, taken in conjunction with the accompanying drawings, in which:
  • FIGS. 1A and 1B are block diagrams first and second examples of a checkout system;
  • FIG. 2 is a wiring-diagram of an example cable connecting a POS terminal to a barcode reader and a scale in accordance with the second example of the present invention;
  • FIG. 3 is a exterior perspective view of a checkout device; and
  • FIG. 4 is a interior view of the checkout device with the scale weigh plate removed.
    • DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENT
  • Referring now to FIGS. 1A and 1B, checkout system 10 includes point-of-sale (POS) terminal 12 and checkout device 14.
  • POS terminal 12 executes transaction processing software 16, which records items for purchase and records payment for the items.
  • POS terminal 12 additionally includes port 18 to which checkout device 14 is connected. Port 18 may be a serial port, such as an RS232 serial port.
  • Checkout device 14 primarily includes barcode reader 20, scale 22, and electronic article surveillance (EAS) system 24.
  • Barcode reader 20 reads barcode labels on purchased items. Barcode reader 20 also sends an enable signal to EAS system 24 through interlock 26 following reading. Barcode reader 20 preferably includes primary port 28 for connection barcode reader 20 to port 18 of POS terminal 12. In addition, barcode reader 20 preferably includes auxiliary port 30 to which other peripherals, such as scale 22 are connected. Primary and auxiliary ports 28 and 30 may be serial ports, such as RS232 serial ports. Barcode reader 20 may include an NCR model 7882 barcode reader.
  • Scale 22 weighs purchased produce items. Scale 22 may include a Mettler Toledo model MT8217AS scale.
  • EAS system 24 deactivates security labels on purchased items that have them. EAS system 24 senses the presence of a security label and deactivates the security label. EAS system 24 may be connected to auxiliary port 30 or to interlock 26. If present, interlock 26 activates EAS system 24 in response to an enable system from barcode reader 20. Thus, interlock 26 signals EAS system 24 to detect a security label only if barcode reader 20 has read a barcode label.
  • POS terminal 12 and checkout device 14 may be coupled in various ways. In a first example embodiment (FIG. 1A), cable 40 couples port 18 of POS terminal 12 to primary port 28 of barcode reader 20. Cable 42 couples auxiliary port 30 of barcode reader 20 to port 32 of scale 22 and port 34 of interlock 26.
  • Under this example, cables 40 and 42 supply data. Cable 42 additionally supplies power to scale 22 from barcode reader 20.
  • Multiple power connections supply power. POS terminal 12 and barcode reader 20 have their own power connections. Interlock 26 and EAS system 24 share another power connection.
  • In a second example embodiment (FIG. 1B), cable 44 couples port 18 of POS terminal 12 to port 28 of barcode reader 20 and port 32 of scale 22. Cable 44 supplies power to both barcode reader 20 and scale 22 from POS terminal 12. Thus, one less power connection is required in this example. Different terminal configurations of cable 44 are envisioned. One configuration was designed for the IBM model 46XX terminal (FIG. 2).
  • Turning now to FIG. 2, cable 44 is shown in detail. Connector 50 couples to a corresponding connector in port 18 of POS terminal 12. Connector 52 couples to a corresponding connector in port 28 of barcode reader 20. Finally, connector 54 couples to a corresponding connector in port 32 of scale 22.
  • Table I below identifies the function of the pins in connector 50:
    TABLE I
    Pin Function
    1 Logic and Power Ground
    4 Terminal Power (connection OK)
    3 Data signal + (bi-directional)
    2 Data signal − (bi-directional)
    S DC Power +12 volts

    Resistor 56 limits the current flowing from POS terminal to peripherals.
  • Turning now to FIGS. 3 and 4, checkout device 14 is shown in more detail.
  • Scale 22 includes weigh plate 60, base portion 62, and (4) weigh plate support posts 64. Barcode reader 20 and EAS system 24 are sandwiched between base portion 62 and weigh plate 60. Weigh plate supports 64 float on a load cell assembly within base portion 62.
  • Weigh plate 60 includes window 66, which is substantially aligned with window 70 of barcode reader 20. Barcode reader 20 reads barcode labels on items above weigh plate 60 through window 66.
  • An example EAS system 24 includes electromagnetic coil 72. Coil 72 may include separate sense and deactivation coils. Corresponding security labels on products include magnetic material. Coil 72 is packaged into a generally rectangular in shape and positioned adjacent barcode reader 20. When mounted in a checkout counter, coil 72 is preferably oriented so that its length dimension is oriented perpendicular to the direction of product movement (arrow). In this way, security labels are exposed to the electromagnetic field from coil 72 after they are moved across window 66.
  • Checkout device 14 is preferably about 11.5 inches in width by 20 inches in length. Advantageously, checkout device 14 fits within a “standard” U.S. checkstand hole for combination barcode reader and scale assemblies.
  • In operation, a product bearing a barcode label and a product security label are moved across weigh plate 60 with the barcode label aimed at window 66. Barcode reader 20 reads the barcode label and sends an enable signal to interlock 26. Interlock 26 signals EAS system 24 to detect the product security label. Coil 72 senses the magnetic material in the security label. Coil 72 demagnetizes the magnetic material in the security label.
  • Although the invention has been described with particular reference to certain preferred embodiments thereof, variations and modifications of the present invention can be effected within the spirit and scope of the following claims.
