Description

DETAILED DESCRIPTION OF THE INVENTION (Field of Industrial Application) The present invention relates to a weighing system in which a plurality of electronic scales and a plurality of receipt issuing machines are connected via a bus line to perform various types of total printing.

(Prior art and its problems) When selling products such as meat and prepared foods by weight at a store, etc., in a sales floor where multiple electronic scales with label printers are installed on a showcase, etc., customers Each item purchased is weighed and priced using the nearest electronic scale with a printer, and payments are made all at once at a cash register.

However, when paying the bill, the price printed on the label must be entered into the cash register, which increases the amount of work at the cash register and reduces sales efficiency when there are a large number of customers. Additionally, there is a risk of input errors occurring when inputting prices, which may lead to problems with the store's credibility.

In order to avoid this situation, a system was developed in Japanese Patent Laid-Open No. 56/1983 that connected multiple electronic scales to one cash register and transferred the price data calculated by each electronic scale to the cash register.
This method has been proposed in Japanese Patent Application Laid-Open No. 51623-1983 and Japanese Patent Application Laid-Open No. 56-51624.

However, in the prior art described above, the electronic scale used is specified in the cash register and the customer's purchase price is input from the specified electronic scale, so multiple customers can purchase two or more electronic scales. When weighing and pricing is performed on each scale, there is a problem in that the purchase price of each customer cannot be sorted out, resulting in incorrect payments being made.

(Objective of the Invention) The present invention solves the problems of the prior art, eliminates the need to re-enter sales prices at the cash register, and moreover allows the sales of multiple customers to be recorded without error. The purpose is to provide a new weighing system that can.

(Summary of the invention) The weighing system of the present invention is configured as follows.

(a) Connect multiple electronic scales and a receipt issuing machine,
The data calculated by each electronic scale is transferred to the receipt issuing machine.

(b) Each electronic scale has a card number to identify the customer.
Attach a card reader to read the data, and read it with the card reader when transferring the data to the receipt issuing machine. It is forwarded with a code that identifies the customer.

(C) The receipt issuing machine is equipped with means for storing the transferred data and a card reader, and at the time of payment, purchase data is read out from the code corresponding to the customer and printed on the receipt.

In addition, each electronic scale is equipped with a label printer, and
The scales are connected to each other via a bus line so that product data registered in each electronic scale can be called up. Further, each electronic scale operates as a scale by inserting a card, but is configured so that product data can be registered only when a master card is inserted.

On the other hand, multiple receipt issuing machines are installed and connected to each other via bus lines, and the configuration is such that purchase data of all customers can be printed on receipts from any of the receipt issuing machines, and at least one of them is the master machine. It is configured to function as a master machine by inserting a card and to be able to tally sales etc. by product category.

(Example) Hereinafter, one embodiment of the present invention will be described with reference to the drawings.

FIG. 1 is a schematic diagram of the configuration of the weighing system of the present invention.
As shown in the figure, a plurality of electronic scales No. 1 to No. n and a plurality of receipt issuing machines No. 1 to No. m are connected by a bus line. Each electronic scale and receipt issuing machine has
A card reader is provided for each card used by the customer or the sales staff, and this point is a feature of the present invention. The function of the card reader will be described later.

FIG. 2 is a schematic diagram of the configuration of each electronic scale. The weight of the product is detected by a weight detector l using a load cell, etc.
After being converted into a digital value by a D converter 2, it is input to an arithmetic control section 4 comprised of a microcomputer or the like. The arithmetic control section is provided with a memory (not shown), in which product data such as call number, product name character code, product code, unit price, etc. is registered in advance for each product by key operation of the key human power section 3. (see Fig. 4), and the price of the product is calculated from the weight, unit price, and tare of the product. Necessary items such as unit price, price, weight, etc. are displayed on the display section 5 and printed on the label by the label printer 6. The customer or the operator inserts the card 7 into the card reader 8, and the data on the card is input to the arithmetic control section 4.

Here, how to use the card is to hand the card to the customer at the entrance of the store, and when weighing and pricing, the sales staff takes the card from the customer and inserts it into the electronic scale, and the weighing and pricing is done after the store is finished. The card is returned to the customer and collected at the time of payment at the cash register. Alternatively, instead of handing the card to the customer, the person in charge carries the card and one person responds to each customer and weighs and prices.The latter method is also acceptable. In this case, in order to understand the sales status of each person in charge, the receipt issuing machine performs aggregation by person in charge, which will be described later.

FIG. 3 is a schematic diagram of the configuration of each receipt issuing machine in FIG. The signals from the card reader 18 are input to an arithmetic control section 14 composed of a microcomputer or the like, and necessary items such as the card number of the card 17 are displayed on a display section 15. Also, receipt printer 1
6, the total details of the customer's purchased products are printed out on a receipt. Note that the receipt printer also performs various necessary tally prints, such as tally prints by time zone and by product category.

FIG. 4 is an explanatory diagram of an example of the product name registration area provided in the memory built in the calculation control unit 4 of each electronic scale. Each product data is stored in the memory as a numerical value of a predetermined number of digits.

Next, regarding the operation of the weighing system of the present invention, FIGS.
This will be explained with reference to the flowchart in FIG. First, the following preparations (1) to (3) are performed.

(1) A plurality of electronic scales and a plurality of receipt issuing machines are arranged according to the layout of the sales floor of the store, and each of them is connected by a bus line.

(2) Set each electronic scale and receipt issuing machine to initial setting mode, set the device number (polling No.) in order from No. 1, and master one of the multiple receipt issuing machines. device, and other devices are used as slave devices.

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

FIG. 5 is a program flowchart of each electronic scale. Next, the operation of each electronic scale will be explained using this flowchart.

(1) Turn on the power and perform the necessary initial settings (step ax). Then, store a message instructing card insertion in the display register (step a2). The contents stored in this display register are as follows: It is output and displayed on the display by a constant periodic interrupt.

(2) If there is a communication request (step ag), input and store the communication data (step a, 4).0 If the communication request is for self-call (step a5), what is the type of received data? If it is single item tally data, it is added to the tally memory corresponding to the calling number and stored (step a7), and a completion signal is sent to the called electronic scale (step a). Day).

(3) If the received data is call data, search the memory registration area using the call number in step a1.
0) if there is a calling number (step a1o), calls the electronic scale requested to send and transmits the registered data (step att); if there is no called number, calls the requested electronic scale and sends the registered data (step att). , send data without a number (step a12). &t
4) Check the card reader (step a1)
5). If the card is set (step aSS)
, the card number is displayed for a predetermined period of time, for example, 5 seconds (step a1), and the process proceeds to MAIN-A.

In this way, even if the power is turned on, unless a card is inserted, each electronic scale does not function as a scale, but only as a transmitter/receiver. is received by the person in charge and is in the possession of the person in charge.

The person in charge inserts it directly into the card reader.

(5) When moving to MAIN@A processing, the electronic scale performs the following steps: subroutine C → step At (checking printing conditions) → step A2 (checking key-on) → step A5 (checking card reader) → step A4
(Checking the card set) → Repeat the process of subroutine C, and monitor calls from other electronic scales in between.

Here, in the weighing process (step A0) of subroutine C.

■Auto tracking processing ■Weigher stabilization processing ■Processing that converts the output value of the A/D converter into a weight value ■Processing that calculates the amount of money (converts the calculated result into a segment code and stores it in the display register This includes processing, etc.

Further, the weight, unit price, amount of money, etc. of the product are displayed by outputting the contents stored in the display register to the display at regular intervals.

(6) At step A2, when the product call number is input by key-on, the process moves to the key processing program shown in FIG. Here, a flowchart of the key processing program will be explained.

■If the call key is turned on (step b1),
Using the call number, a registration area of the memory in which product data such as the product name, unit price, effective date, etc. of the product is stored is searched (step b2). If the call number is registered in the machine's memory (step b3), the registered data is read out, the product name data is developed into a dot image and stored in the printing buffer memory, and the unit price is stored in the unit price register ( Step b4).

■If the calling number is not registered in its own memory, it calls another electronic scale using a polling method and requests the transfer of registered data. On the other hand, other electronic scales monitor calls from other electronic scales between each process, and when they are called, they search the memory registration area with the received call number and confirm the call number. If there is, call the electronic scale for which the call request was made and transfer the corresponding registered data,
If there is no data, data without a calling number is transmitted (processing of subroutine B). In this way, it communicates with each electronic scale in turn until the registration data is transferred.

The above process is repeated until communication with all electronic scales is completed, and if there is no registered data even after communicating with all electronic scales, an error is displayed as an operation error (step b5).
~bxo).

■If the call key is not processed in step b1, check whether the code number of the card is a master code (held only by merchants, etc.). For example, the main function key is checked (step b12). If the wood key is on, then it is checked whether the code number entered with the numeric keypad is in registration mode or not, and if it is in registration mode (step b15), product data registration processing is performed (
Step b14) aAlso, if the recitation number is not in the registration mode but in the tally mode (step bxs), the sales tally for each product name (single item tally) is printed (step bzs), and other key processing, e.g. Processing such as tare setting, zero key, numeric keypad, etc. is performed (step b17).

(7) Returning to the flowchart in Figure 5 again, the product data is set as described above, the weight, amount, etc. of the product being delivered are stably calculated and displayed, and the printing conditions are set, then step A label is issued on A5 paper, and then the data such as the product name, unit price, weight, amount, etc. used for printing is
It is sent to the master machine of the receipt issuing machine together with the code No. 6 of the card by customer (by person in charge) (step ala
) *Next, check the electronic scale in which the name of the product was registered (step aIS). If it is your own machine, add the data to the tally memory corresponding to the call number and store it (
Step a2o (see step a17), if it is another electronic scale, call the registered electronic scale and send the single item data (step a2t), 1. This single item data includes the sales of the called product. Includes number, weight, amount, etc.

Next, the operation of the receipt issuing machine will be explained. Each receipt issuing machine has the same program content, but only the receipt issuing machine set as the master machine in the initial setting mode can print totals by person in charge, totals by time zone, and totals by major category. In addition to being able to print out totals by category, you can also specify one category and register settings such as a master code to specify the store owner. In addition, all data transferred from each electronic scale is stored in the master machine, and when a customer pays with a receipt issuing machine (slave machine) other than the master machine, the customer's purchase data is transferred from the master machine to the slave machine. Have them forward it to you and issue a receipt.

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

(1) When the power is turned on, each receipt issuing machine executes the predetermined initial settings and then displays "0N-LINE" on the first display.
``Message is displayed, and then, while monitoring calls from other electronic scales and receipt issuing machines (master ja) (subroutine D), card insertion is checked.

(2) Since data is randomly transferred from each electronic scale to the master machine, step D is performed every time the master machine is called. (Checking received data) The process moves to step D1, and the received registration data are stored in the registration area in the order in which they were received.

(3) If there is a request for data transfer from the slave device, proceed to step D. →Step D2 (Received card code N
o, to search the area) → Step processing (Check the presence or absence of data) → Step processing (Call the slave receipt issuing machine that received the transmission request and send the first detected registration data@) → Step processing (Sent Clear the registered data and fill the area) → Subroutine E (Communication request exists → Communication data input and storage → Self-calling exists → Registered data exists → Received data is stored in the registered area in order) →
Step D2. By repeating the step process, purchase data of a specific customer randomly stored in the registration area is read out and transferred in the order of registration. Also, during this time, the master machine only monitors calls from each electronic scale (subroutine E).

(4) On the other hand, the slave machine receives data transmitted from the master machine only when it requests data from the master machine. Therefore, each process from step D2 to step ntt is not executed by the slave machine.

(5) Payment for purchased items will be made at the nearest receipt issuing machine. First, insert the customer-specific (person-specific) card into the card reader of the receipt issuing machine and press the total key. Before the card is inserted, subroutine D →
Step Br (card reader check) → Step B
2 (New card set) → The loop process of subroutine D is repeated, and when a card is inserted, step B2
Shift to ■, subroutine D → step Bs
(Card reader check)→Step B4 (Card set)→Step B5 (Key-on check)→Subroutine D loop processing is repeated.

Next, when the total key is pressed, the process moves from step Bs (total key on) to step B7 (checking whether or not the own machine is the master machine), where it is determined whether the machine is a master or a slave.

(6) The card code number received on the master machine.

Search the registration area (Step 8), and if there is relevant data (Step B9), read it out and print the details of the purchased item on the receipt (Step B1), for such one item. When printing is completed, a call from the electronic scale is checked in subroutine E, and if there is a call, registration data is received and stored in the registration area. If there is no call, the process returns to step 8 and searches the registration area again to search for the data of the 5th purchased product.

In this way, while monitoring the calls from the electronic scale, the items purchased by the customer are printed one by one on the receipt, and finally the total is printed (Step B□2), and "0" is printed.
After displaying "0N-LINE", the process of subroutine D is executed, and then the card insertion for each customer (for each person in charge) is checked, but if the card is still inserted. In this state, the process does not proceed to the process after ■.The process in ■ will not be executed unless the card is removed and inserted into the card reader again.

(7) The slave machine does not need to receive the data transmitted from the electronic scale, so when the total key is operated, step 1
Receive registration data via 3tx and print it on the receipt as details of the purchased product.

In addition, when the slave device requests data transfer to the master device in step Bll, the master device performs subroutine D.
Steps D2 → D3 → D4 → D5 groan subroutine E
→Repeat the loop process of step D2 to transfer the registered data.

(8) To perform tally printing using the master machine, proceed as follows.

■Check that your machine is the master machine (step cr) and that the card code number is the master code (step C3), and if these conditions are not met, an operation error will be alerted (step C2), as follows. In other words, unless the store owner or the like uses a MasterCard, various types of tally printing are not performed, so that only MasterCard holders manage merchandise.

■Aggregation key by card (by person in charge) (step C4), aggregation key by time period (step c6), aggregation key by product major category (step c day), aggregation key by product category (step C
In accordance with the operation of IG), the total printing of each item is performed (step C5lc71 c91 cl 1
) - ■ When the registration key is turned on (step C-12)
, various data registration processing is performed (step C15).
), when the clear key is turned on (step C13), the total data etc. are cleared (step C14). Daily totals and
Unless the total data is cleared, the cumulative totals, for example weekly or monthly totals, are printed on the receipt at the same time.

(Effects of the Invention) As explained above, according to the present invention, when a plurality of electronic scales are set up in a sales floor and a plurality of customers purchase products,
It is possible to accurately record the purchase price for each customer without having to input it again at the cash register. Furthermore, by using a plurality of electronic scales and receipt issuing machines, prompt processing can be performed without reducing sales efficiency even during times when customers are concentrated.
