Each electronic balance and receipt issuing machine are provided with a card reader for a card used by a customer or a person in charge of a sales floor, respectively, which is a feature of the present invention. The operation of the card reader will be described later.

FIG. 2 is a schematic diagram of the configuration of each electronic balance. The weight of the product is detected by the weight detector 1 using a load cell, etc.
After being converted into a digital value by the D converter 2, an electronic weighing arithmetic control unit 4 composed of a microcomputer or the like
Is input to The arithmetic control unit is provided with a memory (not shown), and product data such as a call number, a product name character code, a product code, and a unit price are registered in advance by a key operation of the key input unit 3 for each product. The price of the product is calculated from the weight (see FIG. 4), the unit price and the tare of the product. Required items such as unit price, price, and weight are displayed by the display unit 5 and printed on a label by the label printer 6. The customer or the operator inserts the card 7 into the card reader 8, and the data of the card is input to the electronic weighing arithmetic control unit 4. Further, the electronic balance calculation control unit 4 has a communication processing function, and transmits and receives data according to a communication request between each electronic balance and the receipt issuing machine connected by the bus line as described above. be able to.

Here, as for the use of the card, when giving the card to the customer at the entrance of the store and performing weighing, the salesperson in charge receives the card from the customer and inserts it into the electronic scale, and after completing the weighing, the card is sold to the customer. Returned to the cashier and collected at the cash register. Alternatively, a method may be adopted in which the person in charge carries the card without giving the card to the customer, and one person in charge responds to one customer to perform the weighing. When the latter method is used, the receipt issuing machine performs a totaling for each person to be described later in order to grasp the sales situation of each person in charge.

FIG. 3 is a schematic view of the configuration of each receipt issuing machine. In the figure, signals from a key input unit 13 and a card reader 18 are input to a calculation control unit 14 for a receipt issuing machine composed of a microcomputer or the like, and necessary items such as a card number of a card 17 are displayed on a display unit 15. Is done. In addition, the receipt printer 16 prints out a total statement of the purchased products of the customer on a receipt. In addition, receipt printers, such as total printing by time zone, total printing by product category, etc.
The necessary tally printing is also performed. The receipt issuing machine operation control unit 14 has a communication processing function similarly to the electronic balance operation control unit 4, and requests communication between each electronic balance connected via a bus line and the receipt issuing machine. Can be transmitted and received in response to the request.

FIG. 4 is an explanatory diagram of an example of a product name registration area provided in a memory built in the arithmetic and control unit 4 of each electronic balance. Each product data is stored in the memory by a numerical value having a predetermined number of digits.

Next, the operation of the weighing system of the present invention will be described with reference to the flowcharts of FIGS. First, the following preparations (1) to (3) are performed.

(1) A plurality of electronic balances and receipt issuing machines are arranged according to the arrangement of the sales floor of the store, and connected by their respective bus lines.

(2) Set each electronic balance and receipt issuing machine to the initial setting mode, and set the device number (polling number) to No.
One is set in order from 1 and one of the plurality of receipt issuing machines is registered as a master machine, and the other is used as a slave machine.

(3) Each electronic balance is preset with different product data (product name, unit price, etc.).

FIG. 5 is a program flowchart of each electronic balance. Next, the operation of each electronic balance will be described with reference to this flowchart.

(1) Turn on the power and make necessary initial settings (step a ₁ ). Next, a message instructing card insertion is stored in the display register (step a ₂ ). The contents stored in the display register are output to the display unit and displayed on the display by interruption at a constant period.

(2) If there is a communication request (step a _3), and stores the input communication data (Step a _4). If the communication request is a ship call (step a _5), the type of communication data to check what is (step a _6). If single item summary data, the data is stored is added to the aggregate memory corresponding to the call number (step a _7), and transmits a completion signal to the electronic balance of the called (step a _8).

(3) If the received data is call data, search the registered area of the memory by the call number (step
a _10), if there is call number (step a _10), by calling the a electronic balance of the transmission request transmits the registration data (step a _11). If there is no calling number, call the electronic balance for which the request to transmit data without number (step a _12).

(4) Then, check the end of A / D conversion (step a)
₁₃₎ performs automatic tracking processing for correcting the shift of the zero point due to temperature drift (step a _14), to check the card reader (step a _15). If the card is set (step a _16), a card number predetermined time, for example, display 5 seconds (Step a _17), M
The processing shifts to AIN · A processing.

In this way, as long as the card is not inserted even when the power is turned on, each electronic balance does not function as a scale, but only functions as a transceiver. The card is received by the person in charge when the customer has the card, and the card person is directly inserted into the card reader when the card is carried by the person in charge.

(5) When the process shifts to the process of MAIN · A, the electronic balance reads the subroutine C → step A ₁ (check printing conditions) → step A ₂ (check key-on) → step A ₃ (check card reader) → step A ₄ (Check the card set) → Repeat the process of subroutine C, and monitor the call from another electronic balance in the meantime.

Here, in the weighing process (step A ₀ ) of the subroutine C, an auto tracking process, a stabilizing process of the weighing process, a process of converting the output value of the A / D converter into a weight value, a process of calculating the amount of money, a segment code And stores the result in the display register.

The display of the product weight, unit price, price, and the like is performed by outputting the contents stored in the display register to the display unit by interruption at a constant period.

(6) Step A _2, the call number of the product is entered by the key-on, the process proceeds to the key processing program Figure 6. Here, a flowchart of the key processing program will be described.

If the call key is turned on (step b ₁ ), the registration area of the memory storing the product data such as the product name, unit price, and effective date of the product is searched by the call number.
(Step b _2). If the call number is registered in the memory of the own device (step b ₃ ), the registered data is read out, the product name data is developed into a dot image and stored in the buffer memory for printing, and the unit price is stored in the unit price register. (Step
b ₄ ).

If the call number is not registered in the memory of the own device, another electronic balance is called by a polling method and a transfer of the registration data is requested. On the other hand, other electronic balances monitor calls from other electronic balances between each processing,
When the own machine is called, the registered area of the memory is searched with the received call number. If there is a call number, the electronic weigher requested to call is called and the corresponding registered data is transferred, and if there is no data, the call is made. Data without a number is transmitted (subroutine B processing). In this way, until the registration data is transferred, communication with each electronic scale is sequentially performed, and the above processing is repeated until communication with all the electronic scales is completed. to, an error message is displayed as an operation miss (step b ₅ ~b _10).

If not processing of the call key in step b _1,
Check whether the code number of the card is the master code (only owned by the shop owner etc.) (step b)
_11), checks the * key of the function keys if YES (the step b _12). * If the key is on, then it is checked whether or not the recite number entered with the numeric keypad is in the registration mode.
₁₃ ) Perform product data registration processing (step
b ₁₄ ). Further, if the recitation number aggregation mode rather than the registration mode (step b _15), aggregation of sales for each product name and printing (single aggregate) (Step b _16), the other key processing, e.g. tare Ya performs processing such as zero key or numeric keys (step b _17).

(7) Returning to the flowchart of FIG. 5 again, the commodity data is set as described above, the commodity on the scale is stabilized, the weight, the amount of money, etc. are calculated and displayed. label issuing at a ₅ is performed, followed by transmitting, product name that is used for printing, unit price, weight, data amounts or the like, a customer-specific (person-in-charge) master unit of the receipt issuing machine with the card code No. is (step a _18). Next, the electronic balance in which the product name of the product is registered is checked (step a ₁₉ ). If it is the own device, the data is added to the totaling memory corresponding to the call number and stored (step a ₁₉ ).
_20, The reference step a _17). For other electronic scales,
Call the electronic balance that has been registered and transmits the single item data (step a _21). The single item data includes the sales quantity, weight, amount, and the like of the called product.

Next, the operation of the receipt issuing machine will be described. Each receipt issuing machine has the same program contents, but in the initial setting mode, only the receipt issuing machine set as the master machine prints total printing by person in charge, total printing by time zone, total printing by major category In addition to being able to perform total printing by medium classification, etc., the contents can be set and registered such as a classification designation and a master code designating a shopkeeper. In addition, all data transferred from each electronic balance is stored in the master machine, and when a customer pays out on a receipt issuing machine (slave machine) other than the master machine, the data purchased by the customer is transferred from the master machine to the slave machine. Have them forwarded and issue a receipt.

FIG. 7 is a flowchart showing the operation procedure of the receipt issuing machine. Next, this flowchart will be described.

(1) When the power is turned on, each receipt issuing machine performs a predetermined initial setting, then displays an “ON-LINE” message on the display unit, and subsequently displays another electronic balance or a receipt issuing machine (master). Check the card insertion while monitoring the call from the device (subroutine D).

(2) In the master unit, because the random data from the electronic scale is transferred, every time there is a call to the master unit, the steps D ₀ (check of the received data), the processing proceeds to step D _1, received The registered data is stored in the registration area in the order received.

(3) If there is a request for data transfer from the slave device, (searching an area in the card code received No.) Step D ₀ → Step D ₂ → Step D ₃ (the data existence check) → Step D ₄ (transmission Calls the requested slave receipt issuing machine and sends the first detected registration data)
→ Step D ₅ (clear the transmitted registration data and fill the area) → Subroutine E (communication request → communication data input storage → own machine call → registration data → reception data stored in registration area in order) → Repeat the step processing of step D ₂ , which was randomly stored in the registration area,
Read and transfer purchase data of a specific customer in the order of registration. In the meantime, the master machine monitors only the call from each electronic balance (subroutine E).

(4) On the other hand, the slave device receives data transmitted from the master device only when requesting data from the master device. Therefore, the processes of steps D ₂ ~ Step D ₁₁ is not performed in the slave machine.

(5) The settlement of the purchased goods is performed at the nearest receipt issuing machine. First, a customer-specific (person in charge) card is inserted into the card reader of the receipt issuing machine, and the total key is pressed. Before the card is inserted, subroutine D →
Step B ₁ (Check card reader) → Step B
₂ loop (new card set) → subroutine D is repeated and the card is plugged, the process proceeds to step B ₂ Kalai, subroutine D → Step B ₃ (the card reader checks) → Step B ₄ ( (Set card) → step B ₅ (key-on check) → loop processing of subroutine D is repeated. Then, the total key is pressed, the process proceeds to step B ₆ (total key-on) → Step B ₇ (check whether own apparatus or the master machine), the master, slave determination is made.

(6) searches the registration area in the card code No. received in the master unit (Step B _8), if there is the corresponding data (Step B _9), the read printing the details of the purchased item to the receipt by it ( Step B ₁₀ ). When the printing of one item is completed, the subroutine E
To check the call from the electronic balance, and if there is a call, receive the registration data and store it in the registration area. If there is no call, it searches the registration area again returns to step B _8, then search the data of the goods were bought.

In this way, while monitoring the call from the electronic scales continue to print the sequential receipt of the item the customer bought, to print the last total (step B _12), "ON-
LINE "is displayed. After the display of" ON-LINE ", the process of subroutine D is executed, and thereafter, the insertion of a customer-specific (person in charge) card is checked. The processing does not proceed to the processing after step A. The processing of step a is not executed unless the card is removed and inserted again into the card reader.

(7) Since the slave unit does not need to receive the transmission data of the electronic scale, when the total key is operated, step B is performed.
_{In step 11} , the registration data is received, and it is printed on the receipt as the details of the purchased product. Further, when the slave machine requests data transfer to the master device at step B _11, the steps of the master machine subroutine _{D D 2 → D 3 → D} 4 → D 5 →
Repeat loop subroutine E → Step D _2, and transfers the registration data.

(8) To perform total printing by the master machine, the following processing is performed.

The own machine is the master machine (step c ₁ ), and the code number of the card is the master code (step c ₁ ).
c ₃₎ checks to alert operational errors If this condition is not satisfied (step c _2), does not perform aggregate printing process follows. That is, unless the store owner or the like uses the master card, various tabulation printing is not performed, and only the owner of the master card performs product management.

Operation of total key for each card (by person in charge) (step c ₄ ), total key for each time zone (step c ₆ ), total key for each major category of product (step c ₈ ), total key for middle category (step c ₁₀ ) depending on the aggregate printing of each item is performed (step _{c 5, c 7, c 9} , c 11).

When the registration key is turned on (step c _12), registration processing of various data is performed (step c _15). When the clear key is turned on (step c _13), clears the aggregation data, etc. (step c _14).

In the above embodiment, the processing on the electronic balance side when the customer purchases the product with each electronic balance and the processing on the receipt issuing machine side when the customer clears the product with the receipt issuing machine after purchasing the product are performed by the customer. Is described as data exchange in the order along the purchase mode. However, in reality, while a plurality of receipt issuing machines are issuing receipts, each electronic weigher side purchases products, so it seems that data transmission and reception are complicated. The communication processing functions of the control unit 4 and the receipt issuing machine operation control unit 14 do not cause any trouble in exchanging data on the bus line.

In addition, in the processing of the total printing, the total from the previous totaling time to the present totaling time, for example, the total total for each day, and the total total that is accumulated unless the total data is cleared, for example, every week, Alternatively, monthly totals are printed on the receipt at the same time.

(Effects of the Invention) As described above, according to the present invention, when a plurality of electronic balances are set at a sales floor and a plurality of customers purchase products, the purchase price of each customer is input again at the cash register. Accurate accounting can be done without doing. In addition, by using a plurality of electronic balances and receipt issuing machines, quick processing can be performed without reducing sales efficiency even during a time period when customers concentrate.
