Description

[0001]
BACKGROUND OF THE INVENTION
The present invention relates to a two-person product sales registration data processing apparatus in which separate cashiers perform registration processing and settlement processing of products purchased by a shopper.
[0002]
[Prior art]
For example, in a supermarket food department, a two-person product sales registration data processing apparatus has been used.
As shown in FIG. 11, this apparatus includes a scanner device 2 as a registration unit attached to a soccer stand 1 placed along a checkout lane, and a movable register stand arranged inside the soccer stand 1. 3 and a POS (Point Of Sales) terminal 4 as a settlement unit.
[0003]
The scanner device 2 includes a barcode scanner 2a and a registration keyboard 2b as product registration means for registering sales data of customer purchase products. In addition, an operator display 2c and a customer display (not shown) are provided as a display unit for registration for displaying the product name, price, etc. of the customer purchased product. The registration keyboard 2b is provided with a total key for declaring the end of registration of products purchased by one customer.
The POS terminal 4 is placed on the drawer 5 and controls the opening and closing of the drawer 5. The POS terminal 4 includes a settlement keyboard 4a as a registration closing means for declaring the end of a commercial transaction with one customer. In addition, an operator display 4b and a customer display 4c are provided as a settlement display unit for displaying the total amount, change amount, and the like. Furthermore, the printer 4d for printing a receipt etc. is incorporated. The settlement keyboard is provided with a call key for calling sales data of all products purchased by one customer.
[0004]
The merchandise sales registration data processing apparatus having such a configuration uses the scanner apparatus 2 to register merchandise sales data for merchandise purchased by the shopper, and uses the POS terminal 4 to process settlement data with the shopper. It has a two-person mode in which settlement registration work for registration processing is performed by separate store clerk and a one-person mode in which one store clerk performs.
[0005]
Among these, when the two-person mode is selected, a so-called checker who performs product registration work operates the barcode scanner 2a or the registration keyboard 2b of the scanner device 2 to store the sales data of the product purchased by the shopper. Register each product. Then, the sales data of each product is temporarily stored in the memory on the scanner device 2 side. When one shopper completes the registration of products to be purchased and presses the total key, the product sales data of the shopper stored in the memory is transferred to the memory on the POS terminal 4 side. Thereby, the checker can shift to the sales data registration processing of the product purchased by the next shopper.
[0006]
On the other hand, a so-called cashier who handles the settlement registration work presses the call key of the settlement keyboard 4a every time a shopper who has finished registering the purchased product comes. Then, the sales data of all the products purchased by the shopper is called from the memory on the POS terminal 4 side for sales registration processing, and the amount charged for payment is calculated and displayed on the settlement display unit. Accordingly, the cashier receives payment from the shopper for the amount requested for payment, and inputs the payment data from the settlement keyboard 4a. Then, since the receipt is printed and issued by the printer 4d, the receipt is given to the shopper. When the next shopper comes, the call key is pressed again, and the sales data of all products purchased by the shopper is called from the memory.
[0007]
[Problems to be solved by the invention]
However, in the conventional merchandise sales registration data processing apparatus of this type, when the total key provided on the registration keyboard 2b of the scanner apparatus 2 is pressed when the two-person mode is selected, it is stored in the memory on the scanner apparatus 2 side. Since the stored data was transferred to the POS terminal 4 side memory as merchandise sales data for one customer, if the checker accidentally presses the total key during the shopper's purchase merchandise registration, The merchandise registration work for the shopper was deemed to have ended. Here, if the checker notices a mistake and cancels it, there is no problem, but if you continue to register the remaining purchased goods without noticing the mistake, the registration will be registered as the product that the next shopper will purchase. There was a problem causing confusion on the cashier side.
[0008]
Even if there is no problem if the cancel operation is performed, the data transferred to the memory on the POS terminal side by the cancel operation of the total key could not be returned to the memory on the scanner device side. The customer must re-register the product to be purchased from the beginning, and the cashier needs to delete the data transferred to the memory on the POS terminal side by mistake, resulting in a great deal of time and effort. There wasn't.
[0009]
The present invention has been made based on such circumstances, and the purpose thereof is a product that can prevent the problem that the checker continues the registration process of the customer-purchased product without noticing the erroneous operation of the total key. The present invention intends to provide a sales registration data processing apparatus.
It is another object of the present invention to provide a merchandise sales registration data processing apparatus that can easily cancel the erroneous operation and return to the state before the erroneous operation even if the total key is erroneously operated.
[0010]
[Means for Solving the Problems]
  According to the first aspect of the present invention, the sales data of the product registered by the product registration means is displayed on the registration display unit, stored in the registration buffer memory, and stored in the registration buffer memory in response to the input of the total key.

The CPU 11, ROM 12, RAM 13, clock unit 14, I / O port 17, communication interface 19 and controllers 20 to 25 are connected by a bus line 26 such as an address bus or a data bus.
[0017]
The mode switch 16 selects various business modes such as “registration”, “inspection”, “settlement”, “setting”, and instructs the CPU 11 to execute them, and is switched by a key. Incidentally, “registration” is a process for registering the product sales data registered through the barcode scanner 2a and the registration keyboard 2b of the scanner device 2 which is a means for registering product sales data in a predetermined memory area of the RAM 13, and In this mode, transaction settlement data registered via the settlement keyboard 4a of the POS terminal 4, which is a settlement data registration means, is registered in the memory area. “Inspection” is a mode in which the contents of the memory area registered by the “Registration” job are output as a report. “Checkout” is the same as after the contents of the memory area is output as a report. It is a mode of business that clears. “Setting” is a job mode in which data necessary for executing various jobs is set in the memory area in advance.
[0018]
The host device 18 connects the POS terminals 4 installed in each checkout lane and each sales floor in the store with a communication line and manages them centrally, and sells sales data of each product registered for sale via a communication line. The data is collected and collected via the network, and the sales management of the entire store is performed. For example, it is installed in an office in the store.
[0019]
In the settlement keyboard 4a, as shown in FIG. 2, a numeric key such as a monetary amount is entered as a numeric value. A numeric key 31 and a ten thousand-note key 32 of "0" to "9", and a clear that clears the numeric data. Key 33, deposit / cash key 34 for declaring transaction settlement with cash, account key 35 for declaring transaction settlement by credit sale, credit key 36 for declaring transaction settlement by credit, commodity declaring transaction settlement by gift certificate In addition to the ticket key 37, etc., a two-person key 38 for instructing switching between the one-person mode and the two-person mode, and a command for calling sales data of all products purchased by one customer when the two-person mode is selected A call key 39 is provided.
Here, the deposit / cash key 34, the credit key 35, the credit key 36 and the gift certificate key 37 function as a closing key for declaring the end of settlement of one commercial transaction.
[0020]
As shown in FIG. 3, a numerical value data such as a plurality of (1 to 70 in FIG. 3) product keys 41 and sales points are input to the registration keyboard 2b. Numeral key 42, x key 43 for indicating that the numerical value data is a multiplier (sales point), clear key 44 for clearing the numerical value data, and total key 45 for declaring the end of registration of products sold as a commercial transaction In addition to the above, a return key 46 is provided for instructing correction of erroneous operation of the total key 45.
[0021]
In the RAM 13, as shown in FIG. 4, the product name, unit price, tax type, and other statuses are stored in advance corresponding to the PLU code of each product, and the sales score and sales amount of the product are accumulated. In addition to the PLU table 51 to be stored, a registration buffer memory 52 as a scanner device side memory for temporarily storing a PLU code, a sales point, and a sales price of a product purchased by one customer. A total amount summing unit 53, a POS terminal for storing the PLU code, the number of sales, the sales amount and the total amount of the products purchased by the customer in the order of the reference number for identifying the customer who has finished registering the purchased product in the scanner device 2. A settlement buffer memory 54 as a side memory, and a registration count for counting the number of customers who have performed sales data registration processing of purchased products in the scanner device 2 55. Settlement counter 56 for counting the number of customers who have paid for the purchased goods at the POS terminal 4; two-person flag F1 set to “1” when the two-person mode is selected; Various flag data such as a registration flag F2 that is set to “1” during the registration process of customer purchased products, and a post-total flag F3 that is set to “1” every time the total key 45 is pressed on the scanner device 2. And the like are formed.
[0022]
Therefore, when the product sales registration data processing apparatus having such a configuration presses the two-person key 38 provided on the settlement keyboard 4a on the POS terminal 4 side, the CPU 11 performs the two-person key process shown in the flowchart of FIG. The program is configured to run.
[0023]
That is, when the CPU 11 detects an input of the two-person key 38 by a key signal input to the keyboard controller 20, the CPU 11 determines the business mode selected by the mode switch 15 as ST (step) 1. Here, if the “registration” mode is selected, it is determined whether or not the registration flag F2 is reset in the flag memory 57 as ST2. If the registration flag F2 is reset to “0”, it is determined in ST3 whether or not the two-person flag F1 is reset in the flag memory 57. When the two-person flag F1 is reset to “0”, the switch from the one-person mode to the two-person mode is instructed, so that the registration buffer memory 52 used in the two-person mode is used. And clears the settlement buffer memory 54. Further, the count values m and n of the registration counter 55 and the settlement counter 56 are reset to “0”, respectively. Furthermore, if the two-person flag F1 is set to “1”, the process proceeds to a registration process for the two-person mode.
[0024]
On the other hand, when the two-man flag F1 is set to “1” in ST3, the switch from the two-man mode to the one-man mode is instructed, so that the two-man mode is used as ST4. The count values m and n of the registration counter 55 and the settlement counter 56 are compared. If the count value m of the registration counter 55 and the count value n of the settlement counter 56 match, it is possible to shift to the single-person mode, so the settlement buffer memory used in the single-person mode Clear 54. If the two-person system flag F1 is reset to “0”, the process proceeds to a registration process for the one-person system.
[0025]
If the registration flag F2 is set to “1” in ST2, the key input is ignored as an operation error because the two-person key 38 is pressed during registration of a product purchased by one customer. To do. If the count value m of the registration counter 55 does not match the count value n of the settlement counter 56 in ST4, the POS terminal of the customer-purchased product registered by the scanner device 2 in the two-person mode The key input is ignored as an operation error because the two-person key 38 has been pressed in the state where the price settlement process at 4 is not yet completed.
[0026]
In the present embodiment, when the registration process in the two-person mode is started by the input of the two-person key 38, the CPU 11 particularly executes the processes shown in the flowcharts of FIGS. The program is organized.
[0027]
FIG. 6 shows a processing procedure of the CPU 11 when a PLU code of a customer-purchased product is inputted by a product barcode scanning operation by the barcode scanner 2a provided in the scanner device 2 or a product key 41 input operation of the registration keyboard 2b. It is a flowchart shown.
In other words, when detecting the input of the PLU code by the input to the scanner controller 25 or the input to the keyboard controller 23, the CPU 11 determines whether or not the registration flag F2 in the flag memory 57 is reset to “0” as ST1. Here, if the registration flag F2 is reset to “0”, it is the first registration of the product purchased by one customer, so the post-total flag F3 in the flag memory 57 is checked as ST2. If the after-sum flag F3 is set to “1”, it is reset to “0”. Next, in ST3, the registration buffer memory 52 and the amount totalizer 53 used for the registration process of the product purchased by one customer are cleared. In ST4, the registration flag F2 is set to "1". When the registering flag F2 is set to “1” in ST1, the process from ST2 to ST4 is not performed because it is the second and subsequent registration of the product purchased by one customer.
[0028]
Next, the PLU table 51 is searched with the PLU code input as ST5, and the product name, unit price, etc. corresponding to the PLU code are read. Then, multiply the unit price by the number of sales points (if the multiplier is entered with the numeric key 42 and the multiplication key 43 immediately before the PLU code is entered, the multiplier, or 1 if no multiplier is entered), If calculated, the PLU code, the number of sales points, and the sales amount are stored in the registration buffer memory 52. At this time, if the same PLU code is stored in the registration buffer memory 52, the current sales point and sales amount are added to the number and amount corresponding to the PLU code, and the same PLU code is stored. If not, the current PLU code, the number of sales points, and the sales amount are stored in the empty area of the registration buffer memory 52 in order.
[0029]
Next, in ST6, the sales amount of the registered product is added to the amount totalizer 53. In ST7, if detailed items such as the product name, unit price, number of sales, and sales price of the registered product are displayed on the registration display (operator display 2c, customer display), this PLU code input process is performed. Exit.
[0030]
FIG. 7 is a flowchart showing the processing procedure of the CPU 11 when the end of the registration processing of the product purchased by one customer is declared by the total key 45 input operation of the registration keyboard 2b.
That is, when detecting the input of the total key 45 by the input to the keyboard controller 23, the CPU 11 determines whether or not the registering flag F2 of the flag memory 57 is set “1” as ST1. Here, when the registration flag F2 is reset to “0”, the key input is ignored as an operation error because the total key 45 is input without registration of the product purchased by one customer.
[0031]
If the registration flag F2 is set to “1” in ST1, the registration counter 55 is incremented by “1” as ST2. Then, the merchandise sales data including the PLU code, the number of sales points, and the sales amount stored in the registration buffer memory 52 as ST3 and the total amount data stored in the amount totalizer 53 are counted by the registration counter 55. The transaction data for one customer having the reference number m is transferred to the settlement buffer memory 54.
[0032]
Thereafter, the next customer transfer notification message is displayed on the operator display 2c in the registration display unit 2c together with the total amount data stored in the amount totalizer 53 as ST4. In ST5, a drive signal is output to the buzzer 16 to cause the buzzer 16 to ring for a predetermined time. (Notification means)
The next customer transfer notification message is a content for notifying the operator of the scanner device 2 that the registration in the scanner device 2 is transferred to the next customer (for example, “it moves to registration of the next customer”). The contents are set in the ROM 12 or RAM 13 in advance. In addition, when it is set in the RAM 13, the contents can be arbitrarily set by the user (store side).
[0033]
After that, when ST6 resets the registering flag F2 in the flag memory 57 to “0” and sets the post-total flag F3 to “1”, the current total key processing is terminated.
[0034]
FIG. 8 is a flowchart showing the processing procedure of the CPU 11 when the erroneous operation correction of the total key 45 is declared by the input operation of the return key 46 of the registration keyboard 2b.
That is, when detecting the input of the return key 46 by the input to the keyboard controller 23, the CPU 11 determines whether the after-total flag F3 in the flag memory 57 is set “1” as ST1. Here, if the post-total flag F3 is reset to “0”, the key input is ignored as an operation error because the return key 46 is input without being immediately after the total key 45 is operated.
[0035]
If the post-sum flag F3 is set to “1” in ST1, the settlement buffer memory is set as ST2 in order to return the registration buffer memory 52 and the settlement buffer memory 53 to the state before the sum key 45 is input. The transaction data whose reference number matches the count value m of the registration counter 55 is deleted from 54 (restoring means).
[0036]
After that, as ST3, the registration counter 55 is counted down by “1”. Further, the next customer transfer notification message displayed on the operator display 2c is deleted. Further, when the registering flag F2 in the flag memory 57 is set to “1” and the post-total flag F3 is reset to “0”, the current return key processing is ended.
[0037]
  Figure 9settlementKeyboard4a call key 39By input operationCalling sales data for all products purchased by one customerIt is a flowchart which shows the process sequence of CPU11 when it is carried out.
  That is, the CPU 11 is a keyboard controller.20By input toCall key 39If the settlement counter 56 is incremented by “1” as ST1, transaction data whose reference number n matches the count value n of the settlement counter 56 is stored in the settlement buffer memory 54 as ST2. Search whether or not. If the transaction data of the corresponding reference number n is not stored (NO in ST3), if the settlement counter 56 is counted down by “1” as ST4, the present call key process is terminated.
[0038]
When the transaction data of the corresponding reference number n is stored in the settlement buffer memory 54 (YES in ST3), the merchandise sales data in the transaction data of the reference number n is stored in the sales point area of the PLU table 51 as ST5. And the sales registration process is performed by adding to the sales amount area for each PLU code. In ST6, the amount requested for payment is calculated based on the total amount data in the transaction data, and is displayed on the settlement display unit (operator display 4b, customer display 4c).
[0039]
Thereafter, as ST7, input of a closing key (deposit / current total key 34, multiplying key 35, credit key 36, gift certificate key 37) is waited. When the tightening key is input, a tightening registration process corresponding to the type of the tightening key is executed in ST8. In ST9, a receipt is printed by the printer 4d, and a drive signal is output to the drawer opening device 5a to open the drawer 5. Furthermore, if the transaction data of the corresponding reference number n is deleted from the settlement buffer memory 54 in ST10, the current call key process is terminated.
[0040]
In the present embodiment configured as described above, when execution of business in the two-person mode is instructed by the input of the two-person key 38, the registration buffer memory 52 and the settlement buffer memory 54 are cleared. . Further, the count values m and n of the registration counter 55 and the settlement counter 56 are reset to “0”, respectively. In this state, a merchandise registration operation for registering sales data of merchandise purchased by the shopper using the scanner device 2 and a settlement registration operation for registering settlement data with the shopper using the POS terminal 4 Can be executed by different store clerk.
[0041]
Accordingly, a so-called checker who performs a product registration operation operates the barcode scanner 2a or the registration keyboard 2b of the scanner device 2 to register sales data of products purchased by the shopper one by one. Then, the registered product sales data is temporarily stored in the registration buffer memory 52. In addition, the sales amount of the registered product is added by the amount totalizer 53. Further, the name, unit price, number of sales, sales price, etc. of the registered product are displayed on the registration display unit.
[0042]
FIG. 10A is a display example when registering merchandise sales data in the operator display 2c in the registration display unit. The operator display 2c is a three-line display and is registered in the first line. The product name “Product AAA” and the sales price “400” are displayed, the sales number “2” and the unit price “200” are displayed on the second line, and the subtotal of the registered products so far is displayed on the third line. The monetary amount “subtotal 1,000” is displayed.
[0043]
In this way, when all registration of the products purchased by one shopper is completed, the checker inputs the total key 45. Then, the registration counter 55 counts up by “1”. Then, the merchandise sales data of the shopper stored in the registration buffer memory 52 and the total price data stored in the price totalizer 53 have the count m of the registration counter 55 as the reference number. It is transferred to the buffer memory for settlement as customer transaction data. At this time, the next customer transfer notification message is displayed on the operator display 2c in the registration display unit 2c together with the total amount data stored in the amount totalizer 53. Further, the buzzer 16 rings for a certain time.
FIG. 10B is a display example of the operator display 2c when the total key 45 is input in the state shown in FIG. 10A, and the next customer transition notification is displayed on the first line of the operator display 2c. The message “Move to next customer registration” is displayed, and the total amount “Total 1.000” is displayed on the third line.
[0044]
Therefore, the checker can confirm that the total key 45 has been input from the message displayed on the operator display 2 c and the predetermined buzzer sound emitted from the buzzer 16.
Here, when the input of the total key 45 is not an erroneous operation, the checker proceeds to registration of the product purchased by the next customer as it is. When the merchandise sales data for one item of the next customer is registered, the registration buffer memory 52 and the amount totalizer 53 are cleared prior to the merchandise sales data registration process.
[0045]
On the other hand, if the total key 45 is input incorrectly, the checker inputs the return key 46 of the registration keyboard 2b. Then, transaction data whose reference number matches the count value m of the registration counter 55 is deleted from the settlement buffer memory 54. Further, the registration counter 55 counts down by “1”, and the next customer transition notification message displayed on the operator display 2c is deleted as shown in FIG. 10C.
[0046]
As a result of this processing, the transaction data transferred to the settlement buffer memory 54 in response to the previous total key 45 operation is deleted from the settlement buffer memory 54. It returns to the state before being done. In addition, the registration buffer memory 52 and the amount totalizer 53 match the state before the total key 45 is operated because the data does not change even if the total key 45 and the return key 46 are operated. Further, since the registration counter 55 is counted down by “1”, it returns to the state before the total key 45 is operated. Further, the post-total flag F3 set to “1” by the operation of the total key 45 is reset to “0” according to the operation of the return key 46, and conversely, the registering flag F2 reset to “0” is returned. It is set to “1” according to the operation of the key 46. Accordingly, the operation of the return key 46 restores each data in the RAM 14 to the state immediately before the total key 45 is operated, and therefore the scanner device 2 continues the sales data registration process for the merchandise purchased by the shopper so far. be able to.
[0047]
As described above, according to the present embodiment, when the two-person mode is selected, the total key 45 of the registration keyboard 2b in the scanner device 2 is input, and the product sales for one customer stored in the registration buffer memory 52 are performed. Each time data or the like is transferred to the settlement buffer memory 54, a warning is issued to the checker that is the operator of the scanner device 2, so that if the total key 45 is erroneously operated, the checker will notice the erroneous operation at that time. Become. As a result, it is possible to prevent the checker from proceeding with the merchandise registration process without noticing the erroneous operation of the total key 45 and causing confusion on the POS terminal 4 side.
[0048]
In this case, since the warning issued to the checker includes a message for displaying on the operator display 2c of the scanner device 2 a message notifying that the next customer registration is to be registered, the checker erroneously operates the total key 45. At that point, you will definitely notice the wrong operation.
[0049]
If the return key 46 is input immediately after the total key 45 is operated, the state of each memory area of the RAM 14 is automatically restored to the state immediately before the total key 45 is operated. Therefore, even if the shopper mistakenly operates the total key 45 during the registration of the product to be purchased, it is possible to return to the state before the erroneous operation only by inputting the return key 46, and the product registration business for the shopper. Will be able to continue immediately.
[0050]
【The invention's effect】
  As detailed above, according to the invention described in claim 1 of the present application.IfIt is possible to provide a product sales registration data processing device that can easily return to the state before the erroneous operation of the measuring key and can immediately continue the product registration business for the shopper.
  In addition, the claims of the present application2According to the described invention, even if the total key is erroneously operated, the checker can notice the erroneous operation at that time, and the merchandise registration process proceeds without noticing the erroneous operation of the total key, resulting in confusion on the settlement unit side. It is possible to provide a merchandise sales registration data processing apparatus that can easily prevent the total key from being returned to the state before the erroneous operation of the total key and can immediately continue the merchandise registration business for the shopper.
