  • the line concentrator while depicted as having a multiposition switch 15, in reality comprises an electronic scanning device which may be connected to all the counters in a store. While the line concentrator at any particular instant, is connected only to a single counter, it scans at a relatively rapid rate from counter-to-counter, in reading the information stored at the respective counters (if any) in turn and in this way services them all.
  • the output of line concentrator 14 is coupled to a' computer 16 which may be located in the store or at some distance from the store.

  • Keyboard 112 permits entry of information concerning articles from which the machine readable portion of label 64 has been damaged or obliterated, items too small to have a label (e .g., chewing gum) or bulky items, such as fertilizer, which may be kept in the bottom portion of shopping cart 108.
  • Keyboard 112 is also used for other miscellaneous entries such as starting the order, requesting a total from the computer, canceling individual items or the entire order and various other inputs. Operation of some of the more important keys will be discussed late in connection with a discussion of the operation of the equipment.
  • Printer 114 receives information from the remote computer 16 and prints the cost of each article along with a portion of the identification number on a paper tape 120.
  • the identification number pemiits easy reference back to the articles if the customer wishes to check her paper tape.
  • Printer 114 also prints totals, tax amounts and other important information on the paper tape.
  • the printer 1 14 is configured such that all printed lines are visible to the checker. Therefore the total amount will be displayed to checker 100 for his verbal transmission to customer 106.
  • Speakers 116 are coupled to reader 70 in a manner to be described, and indicate to the checker that an article has been properly identified. Alternately, circuitry may be employed between the reader and speakers to indicate that an article has not been identified.

  • the CONVEYER BEAM TRANSMIT- TED signal is coupled as one input to AND gate 132.
  • a keyboard 112 contains, among other things, two push buttons labeled respectively START and TOTAL.
  • the START button is. coupled to the set (s) input of flip-flop 142 and the TOTAL key is coupled to the I reset (r) input of the flip-flop.
  • the output of flip-flop 142 labeled ACTIVE is connected as the second input to AND gate 132.
  • the polarities of the two input signals are such that when flip-flop 142 is set and the CONVEYER BEAM TRANSMITTED signal is present, AND gate 132 is enabled and via amplifier 144 drives conveyer motor 56.
  • the absence of CONVEYER BEAM TRANSMITTED signal disables gate 132 stopping motor 56.
  • flip-flop 142 is reset thus disabling AND gate 132 thereby stopping motor 56.
  • Photodiode 94 located at one end of slot 811 is connected to an amplifier 1511 which has two mutually exclusive binary outputs labeled READER BEAM TRANSMITTED and READER BEAM BLOCKED.
  • READER BEAM TRANSMITFED is present when no article blocks the passage of light from light source 92 to photodiode 94.
  • READER BEAM BLOCKED is present when light is blocked from activating photodiode 94.
  • the READER BEAM BLOCKED signal is coupled as one input to AND gate 151. The second input,
  • ACTIVE is generated at flip-flop 142. With both sig nals present at gate 151, solenoid 152 is activated and moves shutter 96 from the path of light from light source 82. When the article 52 has passed slot 30, the
  • READER BEAM TRANSMITTED signal once again appears and the absence of READER BEAM BLOCKED signal deenergizes solenoid 152 allowing shutter 96 to once again cut off light from light source 92 reaching the slot 81). Also when the TOTAL key on keyboard 112 is depressed, resetting flip-flop 142, the absence of ACTIVE prevents solenoid 152 from being energized.
  • validity checker checks, among other things, that the requisite number of digits precede and follow the large black circular area 68 in the center of the label (FIG. 4). It also recognizes the large black outer annulus which indicates the reader has detected the label.
  • Outputs from validity checker 87 are coupled to AND gates 161 and 163.
  • Gate 161 is enabled after the large outer annulus is detected until the validity checker detects circular area 68. Then gate 161 is disabled and gate 163 previously disabled, is enabled.
  • the read receiver output is coupled as a second input to AND gates 161 and 163. Their outputs are coupled to storage device 160 which comprises two storage areas labeled left storage 162 and right storage 164 respectively. During the passage of an article 52 over slot the label is scanned many times.
  • center line 65 Assumea label contains eight digits of information. Then, when the center portion of the label is read, as indicated by center line 65 (FIG. 4) all 16 digits will be recorded in storage device 160, 8 digits in left storage 162 and 8 digits in right storage 164.
  • a comparator 170 coupled to storage device checks for a comparison between the information stored in the left storage portion 162 and right storage portion 164, as required.
  • the comparator has two outputs labeled NO VALID READ and VALID READ which are mutually exclusive binary signals.
  • NO VALID READ When a comparison indicates that the left storage and right storage portions of storage device 1611 contain the same information (reversed in the right storage device) the comparator produces the VALID READ signal.
  • This signal indicates that the information contained in 160 is valid information and is available to be sent to buffer storage 180 for transfer to the remote computer. It is of course, possible that the read circuitry may erroneously read one or more information bits from the same position(s) on both the left and right halves of the label. Then a VALID READ signal would be produced when in fact the label was read improperly. The probability of such an occurrance is so small however as to be nonexistant for practical purposes.
  • the VALID READ signal may be coupled via appropriate circuitry 171 to a speaker or similar sense stimulating device 116 to produce a short duration signal to indicate to the checker that infonnation has been properly read from the label. Alternatively the checker may be signaled in the absence of an article being properly identified by the circuitry shown in phantom.
  • the NO VALID READ signal from validity checker maybe coupled as one input to an AND gate 172.

  • the output of one shot 174 enables AND gate 172 producing via appropriate circuitry 173 a short duration signal to emanate from speaker 116 to indicate to a checker that an article has passed slot 811 and has not been properly identified.
  • AND gate 172 producing via appropriate circuitry 173 a short duration signal to emanate from speaker 116 to indicate to a checker that an article has passed slot 811 and has not been properly identified. In practice, only one of the two methods previously mentioned will be used. It has been found that as a practical matter the signal indicating a valid read has occurred is the more useful of the two to the checker.
  • Line concentrator 14 is also coupled as an output to speaker 116 via amplifier 171. This arrangement permits the computer to audiably signal the checker that file 40 contains no such number as was just received by the computer. A series of short beeps from the speaker (as contrasted with the single beep when an article has been properly scanned) may be used as a warning.
  • VALID READ signal at AND gate 175 permits data from storage device 160 to be transmitted to buffer storage 180.
  • Storage 180 is coupled to line concentrator 14 to transfer data to the computer.
  • Keyboard 112 is also connected to the com puter to permit transmission of information manually entered on its key buttons.

  • a signal is sent from storage device 180 of a check out counter to line concentrator 14 to indicate that the check out counter desires to transmit information to the computer.
  • Line concentrator 14 which is constantly scanning (when not servicing another counter) will detect such a request for service).
  • Switch 15 will stop scanning long enough for information indicative of the article to be transmitted to computer 16 and, if no other counter wishes to transmit data, for return information to be received from the computer.
  • warning light 184 indicates to the checker that he may not scan any more items. The light will be extinguished when the line concentrator has transferred data to the computer. Also an output (not shown) from AND gate 182 may be coupled in such a way as to inhibit speaker 116.

  • the checker normally grasping articles in alternate hands for maximum efficiency continues to move the successive articles over the slot in the manner described, at high speed approximately one article per second. After all regular articles have been processed, identification numbers for small articles and from very large and bulky articles such as may be located in the bottom of shopping cart 108 will be entered on the keyboard and sent to the computer for price look up and inventory adjustment. It should be noted that the position of checker 100 relative to the cart 108 is such as to permit easy viewing of the bottom of the cart. This arrangement is in contrast to the typical supermarket where the checker is located on the opposite side of the counter from the customer and shopping card and thus is not in a good position to see merchandise which may have been left in the bottom of the cart.
  • the checker depresses the TOTAL key located on keyboard 112.
  • the signal produced by the TOTAL key causes motor 56 to cease revolving as previously mentioned.
