Description

Detailed Description of the Invention [Technical Field of the Invention] The present invention provides a method for temporarily storing sales data in each electronic cash register when a situation occurs in which the sales data cannot be stored in the total file of the file control unit. The present invention relates to a POS system equipped with excess and insufficient memory.

[Technical Background of the Invention and Problems Therein When it is necessary to install a large number of electronic cash registers, such as in supermarkets and supermarkets, each electronic cash register is generally connected to one 7-filter control unit via a transmission line. A well-established POS (point of sale) system has been adopted. In such a system, the JAN, PL (product code such as J) of each sales product registered for sale in each electronic 1 sales register during sales registration work is
・Sales data such as 1 department code, sales amount, and number of items sold are registered by department code in the sales registration file formed in the storage section of each electronic cash register, and are also sent to the file control section via the transmission path. The above-mentioned JAN is stored in the tally file created in the storage section of this file control section.
, PLU, etc. are collected 31 by product code. If the file control unit is not equipped with a dedicated printing device, the total data collected from each electronic cash register is stored in the file control unit's total file during the settlement process after the end of the day's sales, for example. The information is sent to the electronic cash register and printed out as a daily settlement report by the master electronic cash register.

However, as mentioned above, the POS system aggregates the sales data sent from each electronic cash register in the aggregate file of the file control unit, and later prints out the aggregated data aggregated in this collection file as a settlement report. The system had the following problems.

In other words, in each electronic cash register that makes up this POS system, a line abnormality may occur in the transmission line connecting each electronic cash register and the file control section for some reason while the sales registration process is being executed, or the file control If a failure occurs in the electronic cash register itself and the sales data of sales items sent from each electronic cash register is not properly aggregated in the tally file, the total sales data registered in the sales registration file of each electronic cash register and the total data compiled in the file control unit's total file do not match. As a result, there was a risk that confusion would arise in the settlement operations performed at the end of the day.

In particular, if the above-mentioned aggregation file cannot be counted before operating the deposit/account key, transaction stop key, return key, etc. during sales registration for one customer, the cashier will be alerted to an abnormal situation. There is a problem in that it takes a lot of time to find out if the aggregated data match at the time of checkout, as people often do not notice that it has occurred.

[Purpose of the Invention] The present invention has been made based on the above circumstances, and its purpose is to eliminate the situation in which sales data cannot be aggregated in the aggregation file of the file control unit in each electronic cash register. Sometimes, by providing excess/deficiency memory to temporarily store this sales data, even if a situation occurs where it is impossible to aggregate into the aggregate file, it is possible to print out the correct aggregate data as an accounting record at the time of settlement operations. Our goal is to provide a POS system.

[Summary of the Invention] In the POS system of the present invention, when a master electronic cash register and each satellite electronic cash register become unable to aggregate sales data into an aggregation file of a file control unit, sales data to be sent to a file control unit is provided. A surplus/deficiency memory is provided to record the data, and after the above-mentioned aggregation impossible state is released, the sales data stored in the surplus/deficiency memory is sent to the file control section, and the total is compiled in the file control section's total file during settlement operations. Receive and block the data at the master electronic cash register.

The link allows you to print out the payment report.

In another invention, the master electronic cash register and each satellite electronic cash register transmit the sales data in the excess/deficit memory to the file control unit during the settlement operation after the aggregation disabled state is released, and also send the sales data as an excess/deficiency data report. I am trying to print it out.

In yet another invention, the master electronic cash register and each satellite electronic cash register include:
A display means is provided to display that sales data is stored in each excess/deficiency memory.

[Embodiments of the invention] An embodiment of the present invention will be described below with reference to the drawings.

FIG. 1 is a block configuration diagram showing the entire POS system of the embodiment, in which one master electronic cash register 3 and four satellite electronic cash registers 4 are connected to one file control unit 1 via a transmission path 2. connected in a closed loop.

The file control unit 1 includes a CP that executes various calculation processes.
U5 and a ROM connected to the CPU 5 via a pass line 6 and storing control programs for inspection, payment, etc.

and a 5DLC (synchronous, data link,
controller) 9.

The master electronic cash register (hereinafter referred to as master E)
(abbreviated as CR) 3 is configured as shown in FIG. 2, for example. That is, a keyboard 11 as a registration input device is provided on the front surface of the housing 10, a display section 12 for displaying the department code, sales amount, try mark, etc. of the sold product on the upper front surface, and a display for customers on the top surface. A receipt issuing port 14 is provided adjacent to the section 13 and the keyboard 11.

As shown in FIG. 3, the keyboard 11 has number keys 15. to 15 for entering the sales amount, number of units sold, PLU code, etc. of sold products. PLu key to be operated when the sold product is registered in the PLU code 16. Department key 17 for entering the department code of the sales item. Subtotal key 1

SR (bottle return) key for receiving empty bottles etc. and returning the cost of the bottle to the customer. Control key key 22 for selecting and setting the business mode
Various function keys such as are arranged.

The control key 22 is a control switch for controlling the power on and off, and instructing the central processing unit to execute various operations such as [registration], [inspection], and [accounting]. [Registration] refers to the task of storing sales data such as the price of sold products in the storage unit, sending it to the file control unit 1, calculating the total price, etc., and printing out the results on a receipt. It is. Also,[
[Inspection] is a job that prints out the total data accumulated in the storage unit in [Registration] on a receipt. This is the task of clearing the contents of the storage unit.

The display section 12 also has a seven-digit amount display section and two one-digit repeat display sections, as shown in FIG.

An 8-digit coat product name display head that displays codes such as JAN, PLU, and product names in the same area, and a plurality of trimmers that display each operating status of this register are arranged. These [Remarks] include a registration mark 23. BR mark 24 indicating that the cost of the empty bottle has been returned. A surplus/deficiency mark 25 or the like is included to indicate that sales data is stored in the surplus/deficiency memory.

FIG. 5 is a block diagram of the master EC, R3. 26 in the figure is a CPU that executes various arithmetic processing on sales data input from the keyboard 11;
The PU 26 connects the keyboard 11 . RAM that stores various control programs such as sales registration programs. RAM that temporarily stores variable data such as sales data input from the keyboard 11.
2'9゜The display section t2'', 13, a printer 30 that prints out the registration results etc. on a receipt.Controls the I/O interface 31 connected to the transmission line 2.

In the RAM 29, in addition to a sales registration file RA1 that aggregates sales data input from the keyboard 11, for example, by department code, there is also a sales registration file RA1 that collects the sales data inputted from the keyboard 11, for example, by department code.
A surplus/deficiency memory RA2 is formed to store sales data to be sent to the file control section 1 when an unallocable state occurs. In this excess/deficiency memory RAl, a number indicating the classification type (1 in the case of PLU classification) is stored for each piece of sales data.
A code area for storing the PIU code, a score area for storing the number of sales items, an amount area for storing the sales amount, etc. are formed.

After the power is turned on using the control key 22 and various initial processes are completed, the CPU 26 of the master ECR 3 performs "registration", "inspection", and "payment" according to the flowchart shown in FIG. 7 when a key signal is input from the keyboard 11. ”
Configured to perform business.

That is, when a key signal is input from the keyboard 11,
First, check the setting business mode from the setting position of the role key 22 on the controller 1. If the setting business mode is the [registration] mode, the type of input key signal is checked. If the key signal is for one deposit/account key in Pl, the 8th
Executes the figure deposit/cash key processing. When the deposit/current key 19 is manually operated, before this deposit/current key is manually operated,
Each sales data of each product sold to one customer has already been registered in the sales registration file RA1, and the PL of the file control unit 1 is
It is determined that the information has been totaled in the U file and has been printed out on a receipt by the printer 30. Therefore, after calculating the total amount and registering the total amount and the number of customers per customer, the printer 30 prints out the total amount and the like on a receipt. The receipt is then cut and ejected from the receipt issuing port 14 to complete the sales registration process for one customer.

In FIG. 7, if the input key signal is a key signal of the PLU key 16, the PLU key process shown in FIG. 9 is executed. That is, when the PLU key 16 is manually operated, this PLU key 16 is operated manually.
Immediately before operating the LU key, after confirming that the PLU code has been set using number key 15, enter this PLU code into the I
10 interface 31. It has an input of an acknowledge (ACK) signal which is sent to the file control unit 1 via the transmission line 2 and indicates that it is registered in the PLU file of the RAM 8. When the permission signal is received, PLU data such as the number of items sold among the sales data is sent to the file control unit 1.

The file control unit 1 that has received the PLU data aggregates the received PLU data into a PLU file in the RAM 8. In addition, just before the key operation of PLU key 16, a number is set to number key 1.
If the number is not set in step 5, it is determined that a repeat operation for continuously registering the same product has been performed, and the <PLU data is sent to the file control unit 1 based on the PLU code set before the repeat operation. do.

Next, the PLU data sent to the file control unit 1 via the I10 interface 31 at P2 is transferred to PLU data of RAM8.
It is checked whether or not a confirmation signal has been received from the file control unit 1 indicating that the LU file has been properly aggregated. When the confirmation signal is input, it is determined that the total has been properly collected, and the sales data is registered by department in its own sales registration file RA1, and the above-mentioned PLU sales data such as the PLU code, number of items sold, and sales amount is printed on the receipt using the printer 30. Print out this PL
Ends U key processing.

Note that if the confirmation signal is not sent from the file control unit 1 at P2, the transmitted PLU data may not be properly stored in the PLU file of RAM 8 due to a line abnormality in the transmission path 2 or an abnormal situation in the file control unit 1. It is determined that the data was not aggregated. Then, the sales data of the PLU data that could not be transmitted is sequentially stored in the excess/deficiency memory RA2 formed in the own RAM 29. If this sales data is the first data stored in the excess/deficiency memory RA2, the excess/deficiency mark 25 on the display section 12 is lit. Thereafter, registration processing for the sales registration file RA1 is performed.

In FIG. 7, if the input key signal is the key signal of the transaction stop key 20, the transaction stop key process shown in FIG. 10 is executed. In other words, when the transaction stop key 20 is pressed manually, if the product registered for sale to one customer before the transaction stop key was operated is a product registered in the PLU file, the PLU data of this product is saved in the file. It is sent to the control unit 1. The file control unit 1 that received the cancellation PLtJ data is stored in the RAM 8.
The data of the corresponding PLU code is subtracted from the aggregated data of the PLU file. When the master ECR 3 receives a confirmation signal indicating that the total data in the PLU file has been properly reduced based on the PLU data sent in P3, it also reduces the registered data in its own sales registration file RAI. When the above-mentioned price reduction processing for all products sold to one customer is completed, the result is printed out on the receipt, and the cash registers 1 and 2 are disconnected to complete the transaction stop key processing.

Incidentally, if the conviction signal is not transmitted from the file control unit 1 at P3, it is determined that the transmitted PLtJ data has not been properly reduced and totaled in the PLU file of the RAM 8, as described above. Then, the sales data of the PLU data that could not be transmitted is sequentially stored in the excess/deficiency memory RA2 formed in its own RAM 29 with a (-) sign indicating a reduction. If this sales data is the first data stored in the excess/deficiency memory RA2, the excess/deficiency mark 25 on the display section 12 is lit. Thereafter, a reduction registration process is executed for the sales registration file RAI.

In FIG. 7, if the set business mode is [inspection mode], N1 recognizes that the input key signal is the key signal of the deposit/cash key 19. Once the confirmation is completed, the number entered with the numeric key 15 immediately before the key operation of the deposit/cash total key 19 is checked. If this number is 16 at P4, the sales data sequentially stored in the surplus/deficiency memory RA2 is printed out on a receipt as a surplus/deficiency data report 32 shown in FIG.

In addition, if the number entered with the number key 15 in P5 is 8, the PL of RA tv18 is sent to the file control unit 1.
Sends a request command signal to transmit the total data compiled in the U file. When the total data of the PLU file is received, the total data is transferred to the PLU shown in FIG.
Inspection (print out as payment report 33).

Further, in FIG. 7, if the set business mode is the [accounting] mode, it is confirmed that the input key signal is the key signal of the deposit/cash total key 19.

Once the confirmation is completed, the number entered with the number key 15 immediately before the key operation of the deposit 7/total key 19 is checked.

If this number is 16 in R6, the sales data sequentially stored in the excess/deficiency memory RA2 is printed out on the receipt as the excess/deficiency data report 32 shown in FIG. 11, as in the inspection commode.

Next, the PLtJ data of the sales data is sent to the file control section 1. The file control unit 1 that received this PLU data stores this PLU data in the RAM 8 (pHl).
Aggregate into 1 ile. When the master ECR 3 finishes sending the PLU data to the file control section 1, it clears the stored contents of the excess/deficiency memory RA2, turns off the excess/deficiency mark 25 on the display section 12, and ends this delicate work.

Note that if the number is 16 in R6, the process advances to R5. R
If the number set in 5 is 8, the file control unit 1
A request command signal is sent to send the total data compiled in the PLtJ file of RA v a. And P.L.
When the total data of the U file is received, this collected data is printed out as a PLU settlement (inspection) report 33 shown in FIG. 12, similar to the inspection commode.

The above is an explanation of the external appearance of the master ECR3, the key arrangement 1 of the keyboard, and the configuration of the CPLI26.
The configuration is the same except for the task dedicated to the master register, which prints out the total file data as a settlement (inspection) report using its own printer. Therefore, the explanation will be omitted.

After the power is turned on and various initial processes are completed, the CPU 5 of the fill control unit 1 inputs various business command codes from each satellite ECR 4 and master ECR 3 to the 5DLC 9 via the transmission line 2, and then executes the process shown in FIG. The system is configured to perform registration 1 inspection and settlement operations in accordance with the above.

In other words, when a business command code is input to 5DLC9,
First, the main business code (M, JC) of this business command code
). If the main business code is 1, it is determined that it is a business code related to normal sales registration business.

If this business code is a business code for PLIJ, then RA the unit price corresponding to the entered PLU]-do.
The master ECR read from the PLU file of M8 and sent out this PLU code along with the acknowledgment (ACK) signal.
3 or send to satellite h E CR4. Also, P.L.
If it is a business code to be registered (aggregated) in the IJ file,
The input PLU data is totaled into a PLU file, and when the totalization is completed, a confirmation signal is sent to the ECRs 3 and 4 that sent the PLU data.

If the main business code (~+, JC) is 2, it is determined that it is a business code related to inspection or settlement work sent from the master ECR 3. If this business code is a PLU inspection business code, the total data of the PLU file is sent to the master ECR 3. Also, PLL
If it is an I-settlement business code, the total data of the PLU file is sent to the master ECR 3, and the stored contents of the PLU file are cleared.

In the POS system configured in this way, each EC
14 and 15 show the key operation procedure when the sales data of the product sold to one customer in R3, 4 is entered manually from the keyboard 11 and the memory contents of the excess/deficiency memory RA2 corresponding to the key operation procedure. As shown in the figure.

In Figure 14, one product with PLU code 5 and PL
When 5 products with U code 3 are key-powered, 1 product with code 5 and 2 products with code 3 are key-powered A.
If the PLU file becomes unable to be aggregated at a certain point in time, the sales data keyed after point A will be registered in the sales registration file RAI, but will not be aggregated in the PLU file of the file control unit 1 and will be stored in excess or insufficient memory. The data are sequentially stored in RA2 in chronological order. At the same time, the excess/deficiency mark 2 on the display section 12
5 lights up.

In FIG. 15, when canceling a transaction to return one product name with PLLI code 5.10°7, two product names 3 and 4, and one empty bottle, the last transaction cancellation key 20 is pressed. If the PLtJ file becomes unable to be aggregated at time B immediately before the manual key operation, each PLU data that was manually input before time B will be treated as legitimately sold PLtJ files.
It is aggregated in the U file. Therefore, excess or insufficient memory R
In A2, sales data of each PLU data is stored with a (-) sign attached to each sales point and amount.

At the same time, the excess/deficiency mark 25 on the display section 12 lights up.

Please note that for refunds of empty bottles, there will be a +) sign.

Then, at the time of settlement at the end of the business on the first day after the aggregation impossible state is released, set the business mode of each ECR 3 and 4 to [Settlement] mode, set 16 with the number key 15, and then deposit/cash. When the key 19 is pressed manually, the PLU data in the excess/deficiency memory RA2 is transmitted to the file control section 1 and stored as a PLU file. At the same time, an excess/deficiency data report 32 shown in FIG. 11 is printed out. Further, the excess/deficiency mark 25 is turned off.

Then, set the business mode to [Payment] mode on the master ECR3, enter the number 8 with the number key 15, and press the Deposit/Cash total key 19 manually.Then, the PLU payment check (inspection) report shown in Figure 12 is performed. 33 is printed out.

In this way, even if the PLU file of the file control unit 1 becomes unable to collect PLU data for some reason while executing sales registration work for one customer, these PLU data will be The data is once stored in the excess/deficiency memory RA2 provided in each ECR 3, 4, and after the state where it is impossible to tally is released, it is tallied again in the PLU file. Therefore, an accurate PLU settlement report can always be automatically and easily obtained during settlement operations.

In addition, if the PLU file falls into a state where aggregation is impossible and the PLU data is stored in the excess/deficiency memory RA, the display unit 12
Since the surplus/deficiency mark 25 lights up, it is possible to prevent the cashier from forgetting to send the data in the surplus/deficiency memory RA2 to the file control unit 1 at the time of payment.

[Effects of the Invention] As explained above, according to the present invention, when a situation occurs in which sales data cannot be aggregated in the aggregation file of the file control unit in each electronic cash register, this sales data is temporarily stored. An excess/deficiency memory is provided, and the sales data stored in the excess/deficiency memory is aggregated into a total file after the state in which aggregation is impossible is canceled. Therefore, even if it becomes impossible to perform aggregation in the aggregation file, correct aggregation data can be printed out as a settlement report during settlement operations.
