Description

DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention relates to an electronic cash register that can perform interrupt registration operations for other customers during registration operations for one customer.

[Prior Art] Generally, in an electronic cash register, sales data such as the department code and sales amount of each product sold to one customer are entered using number keys, department keys, etc. arranged on a keyboard as an input device. When the keys are pressed one after another, each department code is registered in, for example, a department registration file provided in the internal storage section, and is printed out on internal recording paper called a receipt and journal, and roughly displayed on the display section. Then, when the key input of the sales data for all the sold products is completed, if you perform a closing operation such as the current key input, the total amount will be calculated and a receipt will be generated.

It is printed out on the journal and displayed on the display section. Then, they exchange money with customers.

[Problems to be Solved by the Invention] However, the electronic cash register configured as described above has the following problems that still need to be solved. That is, when one customer purchases many products, the time required to register the sales data of those products on the electronic cash register naturally increases.

In such a case, even if a customer who purchased a small number of items, such as one or two items, wants to check out, he or she will not be able to start registration until the registration process for customers who purchased many items first is completed. Even if a customer purchases only one or two small items, he or she will have to wait for a long time.

Therefore, a large number of customers who have purchased a small number of products will be lined up behind customers who have purchased a large number of products, and there is a concern that the service for the customers who have purchased a small number of products will be degraded and that accounting operations will be congested.

The present invention was developed based on the above circumstances, and its purpose is to enable interruption registration work for products purchased by other customers during registration work for one customer. An object of the present invention is to provide an electronic cash register that can improve services for customers who purchase a small number of products and also facilitate the overall accounting operations.

[Means for Solving the Problems 1] The electronic cash register and cash register of the present invention is capable of inputting an interrupt command that interrupts the registration of sales products for one customer during the registration of sales products for one customer. and an interrupt totalizer that cumulatively stores the sales amount of the sales products input via the input device after the interrupt command is input by the cut command input means. In response to the first tightening operation to be executed thereafter, at least the interrupt total amount accumulated in the interrupt totalizer is displayed on the display section, and the interrupt is registered from the input of the interrupt command to the first tightening operation to be executed. The printing operation on receipts is stopped during the period.

Another invention is an electronic cash register having a plurality of display sections, in which at least one of the plurality of display sections is displayed in response to a closing operation that is first executed after inputting an interrupt command. The total amount of the interruption is displayed in the section, and the display contents immediately before the interruption command is input are continued to be displayed on the remaining display sections during the interruption registration period.

In still another invention, the display contents displayed on the remaining display section during the interruption registration period in the above invention are stored in a main totalizer that cumulatively stores the total amount of products sold to customers who have been interrupted. (subtotal amount).

In another invention, the cut-off command input means 1 has the cut-off totalizer 1 cut-off total amount display means, and receipt printing stop means, and the cut-off command input means 1 has the cut-off total amount display means and the receipt printing stop means, The product sales data and the total amount of the interruption are printed out on internal recording paper with an interruption code indicating that the interruption is registered.

In still another invention, the cut-off command input means 1 interrupt totalizer 1 includes a display means for the cut-off total amount, and a receipt printing stop means, and also includes sales data of customers who have been cut-off after the end of the cut-off registration period. After printing out the total amount on internal record paper, print the sales data and total amount of interrupt registered during the interrupt registration period on internal record paper with an interrupt code indicating that it is an interrupt registration. It is designed to be output.

[Operation] In the electronic cash register configured as described above, when an interrupt command is input to interrupt the registration process of sales items for another customer during the registration process of sales items for one customer. The sales data input after the input of this interrupt command is registered in the sales registration file, and the sales amount is cumulatively stored in the interrupt totalizer. Then, when the sales data input for the cut-off product is completed and the closing operation is executed, the cut-off total amount accumulated in the cut-off totalizer is displayed on the display section. Furthermore, the printing operation on the receipt is stopped during the interrupt registration period.

Further, in another invention, in addition to the above-mentioned effect in an electronic cash register having a plurality of display sections, at least one of the backs of the plurality of display sections is activated in response to a closing operation performed during an interrupt registration period. The total interrupt amount is displayed on one display section, and the display contents immediately before the interrupt command was input are continued to be displayed on the remaining display sections.

Furthermore, in another invention, the remaining display section displays the subtotal amount of the customer who was interrupted immediately before the interruption command was input.

Furthermore, in another invention, the sales data and the total amount of the interruption inputted during the interruption registration period are printed out on internal recording paper with an interruption code indicating that the registration is an interruption registration.

Furthermore, in another invention, the sales data and total amount of the interruption entered during the interruption registration period are internally recorded as the sales data and total amount of the interruption customer input after the end of the interruption registration period. After being printed out on paper, an interrupt code is added to this internal recording paper and then printed out.

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

FIG. 3 is a perspective view showing the electronic cash register of the embodiment. In the figure, 1 is a housing, and the front of the housing 1 is provided with a keyboard 2 as an input device, and the upper part is provided with a main body display section 3 that displays a department code, sales amount 9 total amount, etc. .

Further, a receipt issuing port 4 and a journal (internal recording paper) monitoring window 5 are provided adjacent to the keyboard 2. Further, a drawer 6 for storing money and the like is provided at the bottom.

As shown in FIG. 4, the keyboard 2 includes number keys 7 for inputting numbers such as amounts, department keys 8 for inputting department codes of sold products, and 8 department keys for inputting department codes of sold products. 9. An interrupt key for inputting an interrupt command to interrupt the registration process of sales products for other customers during the registration process.9.
In addition to sales registration keys such as a cash total key 10 for executing a closing operation that calculates and displays the total price for products sold to one customer, a control key 11 operated with a key is provided. has been done.

The control key 11 is a control switch that controls the power supply of the electronic cash register on and off, and also causes the central processing unit to execute various tasks such as [registration], [inspection], [settlement], and [excretion]. .

FIG. 1 is a block diagram showing an electronic cash register, and numeral 12 in the figure carries out various operations such as [registration] and [setting] specified by the control key 11 based on various information input from the keyboard 2. It is a CPU (Central Processing Unit). This CPU 12 has an address bus 13.
．． Data Pasco 4゜IJ lit line 1 wire tube 5 [Register] [ROM 16 that stores fixed data such as various business programs such as settings 1, sales data entered manually from the keyboard 2, variable data such as each totalizer, etc. RAMI that stores

3 and the like are connected to the CPU 12 via a data bus 14 and a control I line 15.

As shown in FIG. 2, the RAM 17 contains a departmental registration file RA1, which is a sales registration file for tabulating sales data such as the sales amount and number of sales items manually entered from the keyboard 2 by department code. , there is a numeric buffer RA that temporarily stores the numbers entered using the numeric key 7.
2. An interrupt totalizer RA3 that cumulatively stores the sales amount of the interrupt product manually operated after the interrupt key 9 is operated manually. Main instrument RA4 that cumulatively stores the sales amount of products sold to one customer during regular registration that is not interrupt registration.Registration flag indicating that registration for one customer is in progress and interrupt registration is in progress. Flag areas RA5, RA6, etc. are formed to respectively store interrupt flags indicating the interrupt.

After the electronic cash register is powered on using the control key 11 and various initial processes are executed, the CPU 12 executes key manual processing according to the flowchart of FIG. 5 when various key signals are input from the keyboard 2. configured to run. That is, when a key signal is input to one keyboard input circuit, the type of the input key signal is checked.

If the input key signal is the key signal of numeric key 7, it is the 6th key signal.
Execute the numeric key processing shown in the figure. That is, the number corresponding to the input number key 7 is stored in the number buffer RA2 of the RAM 17, and is also displayed on the main body display section 3 via the display control circuit 21.

If the input key signal in FIG. 5 is a key signal for the department key 8, the department key process shown in FIG. 7 is executed. That is, when the department key 8 is pressed manually, it is shown that the control key 11 is set to the [registration] business mode and that a number is stored in the number buffer RA2.
i [do. After that, the departmental registration file R in RAM17
The numbers stored in the number buffer RA2 are cumulatively stored as the sales amount in the area corresponding to the department code specified by the department key 8 in Al. Furthermore, 1 is added to the sales score of the corresponding area. Next, check the status of the registration flag in the flag area RAS, and if it is O, registration work for new customers is W@
It is determined that the registration flag has been started and this registration flag is set to 1. If it has already been set to 1, it is determined that the second or subsequent product is being registered for one customer, and the flag state is left as is.

When the registration flag processing is completed, the flag %j is displayed in Pl.
RA, ρ・': Check the interrupt 3 flag status. If the interrupt flag is O, it is a normal registration, not an interrupt registration, so the number buffer RA is stored in the main summator RA4 of the RAIVj17.
The number 2 is cumulatively stored as the sales amount.

At the same time, the printer 22 prints the department code on the receipt and journal via the printer control circuit 23.

Print out the sales amount. , J′1. When the above registration and printing process is completed, the numbers in the number buffer RA2 are cleared.

If the interrupt flag is set to 1 in Pl, it is determined that the interrupt registration period is in progress, and the interrupt totalizer R in the RAM 17 is
The numbers in the number buffer RA2 are cumulatively stored in A4 as the sales amount of the interrupted product. At the same time, via the printer control unit 23, the printer 22 prints out only the department code and a code, e.g., "E discount" indicating that the sales amount is registered at a discount of 1, on the journal only. Then, the numbers in the number buffer RA2 are cleared.

In FIG. 5, if the key human input signal is the key signal of the interrupt key 9, it is determined that an interrupt command has been input to interrupt the registration task for another customer during the registration task for one customer. Execute the interrupt key processing shown in the figure. That is, when an interrupt command is input, after confirming that the [registration] business mode is set and that the registration flag is set to 1, the interrupt flag in the flag area R△6 of the RAM 17 is set to 1. Set.

If the input key signal in FIG. 5 is the key signal of the total key 10, it is determined that the close key operation has been performed, and the total key process shown in FIG. 9 is executed.

In other words, when the current key 10 is entered manually, [Register]
It is set to business mode and the registration flag is 1.
After confirming that the flag f is set in P2,
[Check the state of the interrupt flag of RA6. interrupt flag is 0
If it has been released, it is determined that this is a closing operation during normal registration work, and the total amount accumulated and stored in the main totalizer RA4 is displayed on the main body display section 3. At the same time, the drawer 6 is opened via the drawer control circuit 18.

Roughly, the printer 22 prints out the total amount of the main totalizer RA4 on a receipt and a journal. When the above display and printing processes are completed, the registration flag is reset to 0 and the total amount on the main totalizer RA4 is cleared.

If the interrupt flag is set to 1 in P2, it is determined that this is a closing operation for a product for which an interrupt has been registered, and the interrupt total amount accumulated and stored in the interrupt totalizer RAS is displayed on the main body display. 3
to be displayed. At the same time, the drawer 6 is opened via the drawer control circuit 18.

Furthermore, the printer 22 interrupts the journal only with the totalizer R.
Print out the total interrupt amount on A3. When the above display and printing process is completed, the interrupt flag is reset to O and the interrupt total amount in the interrupt totalizer RA3 is cleared.

In the electronic cash register configured in this way, the printed contents of the journal and receipt when carrying out interrupt registration work for another customer during registration work for one customer are shown in Figs. 10 and 11. explain. In other words, enter the sales data for each product for one customer: 300 yen with department code 1, 450 yen with department code 1, 200 yen with department code 2, 100 yen with department code 1. As you press key 8 one after another, the department code and sales amount will be printed out one column at a time on the journal 24 and receipt 25 shown in Figure 10. If a customer in a hurry arrives and has purchased only three items, the cashier manually presses the interrupt key 9 on the keyboard 2 and orders the customer's purchased department code 2 for 200 yen, 1 department code 1, and so on. When the sales data of each product of 150 yen 1 department code 1 and 50 yen is entered manually using number key 7 and department key 8, the department code and sales amount of each product are marked with c%] sign in the journal 24. are printed out in sequence. Then, when the key input of the sales data for the interrupt customer is completed and the current total key 10 is pressed manually, the total amount of 400 yen for the interrupt customer is printed out in the journal 24 with a [discount] sign attached thereto. At the same time, the total amount of interruption is displayed on the display section 3 of the main body. Note that the department code of the product purchased by the interrupt customer, the sales amount, and the total interrupt amount are not printed on the receipt 25.

When the closing operation with the cash key 1o for the interrupting customer is completed and the exchange of money with the interrupting customer is completed, the remaining customer who was interrupted will receive 150 yen with department code 2 and 1 department code 1.
When the sales data of each product worth 50 yen is entered manually using the number key 7 and the department key 8, the department code and sales amount are sequentially printed out on the journal 24 and receipt 25. Then, when the key input of the sales data of all the products purchased by the customer is completed and the cash key 10 is pressed, the total amount of 1250 yen of the interrupted customer is recorded in the journal 24 and the receipt 2.
5 is printed out. At the same time, the total amount is displayed on the main body display section 3. Thereafter, money is exchanged with the interrupted customer.

In this way, registration work for customers who have purchased only a few products can be interrupted during registration work for customers who have purchased a large number of products, so services can be improved even for customers who have purchased a small number of products, and accounting work can be performed faster. The overall smoothness can be achieved.

In addition, in the present invention, the sales data of the product purchased by the interrupting customer and the total amount of the interrupting charge are not printed on the receipt 25, so the interrupting customer prints the same receipt 25 as in the normal case without registering the interrupting customer. Since the user receives the request, the unpleasantness of being interrupted is alleviated. Furthermore, on the journal 24 in the electronic cash register, the sales data for the customer who was interrupted as well as the sales data for the customer who interrupted are printed together with the [discount] sign indicating that the customer was interrupted, so electronic cash When the register administrator later checks the sales registration data recorded in the journal 24,
It is possible to immediately confirm that an interruption has been registered.

FIGS. 12 and 13 are a perspective view and a block diagram showing an electronic cash register according to another embodiment of the present invention. In the figure, the same parts as those in the embodiment shown in FIGS. 3 and 1 are denoted by the same reference numerals, and the explanation of the overlapping parts will be omitted.

In the electronic cash register of this embodiment, a customer display section 31 is provided in addition to the main body display section 3. This customer display section 31 normally displays the same content as the main body display section 3. Furthermore, the storage contents of the RAM 17 in this embodiment are the same as those shown in FIG.

Roughly speaking, when carrying out the key manual processing shown in FIG. 5, the CPU 12 of this embodiment performs the numeric key processing shown in FIG. 14, the department key processing shown in FIG. 7, the interrupt key processing shown in FIG.
It is configured to perform the current total key processing shown in the figure.

That is, in the numeric key processing shown in FIG. 14, when a number is entered manually using the numeric key 7, this number is stored in the numeric buffer RA2, and then the state of the interrupt flag in the flag area RA6 is checked. If the interrupt flag is cleared to O, it is a normal registration, so the numbers in the number buffer RA2 are displayed on the main body display section 3 and the customer display section 31.

Note that if the interrupt flag is set to 1, the interrupt registration period is in progress, so the number in the number buffer RA2 is displayed on the main body display section 3.

Since the department key processing is the same as that in FIG. 7, the explanation will be omitted.

In the interrupt key process shown in FIG. 15, when the interrupt key 9 is pressed manually, the interrupt flag is set to 1 after confirming that it is in the [registration] business mode and that the registration flag is set to 1. Set to . After that, at P3, main unit RA4
The amount accumulated and stored, that is, the subtotal amount of the interrupted customer is displayed on the customer display section 31.

In the current total key process of FIG. 16, when the current total key 10 is pressed manually, the [registration] business mode and the registration flag = 1 are confirmed as in FIG. 9, and then the flag flil is activated at P4.
Check the state of the interrupt flag of lRA6. Interrupt flag is O
If the registration has been canceled, this is normal registration without interruption, so the total amount on the main totalizer RA4 is displayed on the main body display section 3 and the customer display section 31, and the drawer 6 is opened. and,
Receipt 25. After printing out the total amount on the journal 24, the registration flag is reset to O and the main totalizer RA
Clear 4.

If the interrupt flag is set to 1 at P4, the interrupt registration period is in progress, so the total interrupt amount of the interrupt totalizer RAS is displayed only on the main body display section 3, and the drawer 6 is opened. . Then, the total amount is [discount] for journal 24 only.
After printing out with the sign , the interrupt flag is reset to 0 and the interrupt totalizer RA3 is cleared.

In the electronic cash register configured in this way, when the interrupt key 9 is pressed manually to perform the interrupt registration process for another customer during the registration process for one customer, the interrupted customer's The subtotal amount of the sales amount of the products that were manually operated before the interrupt key 9 is displayed on the customer display section 31. The customer display section 31 maintains the same display content during the interruption registration period. Sales data such as the sales amount of the interrupting customer whose key is pressed after the interruption key number 9 is displayed on the main body display section 31 each time. The total amount of the customer's interruption is also displayed only on the main body display section 31.

Since the subtotal amount of the interrupted customer is continuously displayed on the customer display section 31 during the interruption registration period, the anxiety of the interrupted customer can be alleviated. On the other hand, the customers who cut in can have sales data such as the price of the products they purchased sequentially displayed on the main body display section 3, so that they can similarly relieve their anxiety.

In the interrupt key process of FIG. 15, the display of the subtotal amount on the main totalizer RA4 of P3 may be omitted. in this case,
The customer display unit 31 continuously displays the value of the number buffer RA2 immediately before the key press of the interrupt key 9, that is, the sales amount of the product last pressed by the interrupted customer during the interrupt registration period. be done. Even in this case, it is possible to obtain the same effects as in the above embodiment.

FIG. 17 is a diagram showing the main memory formed in the RAM 17 of an electronic cash register according to still another embodiment of the present invention, and the same parts as in FIG. The explanation of is omitted.

In this embodiment, in addition to each area in Fig. 2, sales data such as the department code and sales amount of each product purchased by the interrupt customer are numbered 1...N... in the order of key input. An interrupt data memory RA7 for storing the interrupt data and an interrupt number counter RA8 for counting the number N of products purchased by the interrupt customer are formed.

Note that the perspective view and block diagram of the electronic cash register are the same as those in FIGS. 12 and 13, which have two display sections, the main body display section 3 and the customer display section 31.

The CPIJ 12 of this embodiment performs the key manual processing shown in FIG. 5 by performing the numeric key processing shown in FIG. 14, the interrupt key processing shown in FIG. Configured to perform key processing. It should be noted that the numeric key processing and interrupt key processing overlap, so a description thereof will be omitted.

In the department key processing shown in FIG. 18, the processing up to P5 is the same as the processing up to P1 in FIG. 7, so the explanation will be omitted.

At P5, if the interrupt flag in the flag area RA6 of the RAM 17 is divided by Ol, :111, it is a normal registration, and as mentioned above, the number in the number buffer RA2 is set in the main totalizer RA4 as the sales amount. Add and receive receipt 2
5. The department code and sales amount are printed out on the journal 24. After that, the number buffer RA2 is cleared.

If the interrupt flag is set to 1 at P5, the interrupt registration period is in progress, so the number in the number buffer RA2 is added to the interrupt totalizer RAS as the sales amount. After that, R
The count flN of the interrupt number counter RA8 of AM17 is set to 1.
, and store the entered department code and sales amount in the Nth area indicated by the count l1iN of the interrupt counter RA8 of the interrupt data memory RA7. When the storage is completed, the number buffer RA2 is cleared.

In the current total key process of FIG. 19, when the [registration] business mode and the registration flag=1 are confirmed, the state of the interrupt flag is checked in P6. If the interrupt flag is set to 1, this is a closing key operation for a product that has been registered as an interrupt.
The total interrupt amount of the interrupt totalizer RAS is displayed on the main body display section 3, and the drawer 6 is opened. If the interrupt flag is cleared to O at P6, this is normal registration with no interrupts, so we will omit the explanation and proceed to Pl. At Pl, the count number of interrupt counter RA8 N fJ< O Find out whether or not. If N=O, it is determined that there was no interrupt registration during the registration process, and the process is terminated.

If the count number N is not 0 at Pl, it is determined that an interrupt has been registered, and after checking again at P8 that the count value Nh is not < o, it is stored in the Nth area of the interrupt data memory RA7. The department code and sales amount are read out and printed out on the journal 24 with a [discount] sign added thereto. When the printing of the sales data for one interrupt product is completed, the count value N of the interrupt number counter RA8 is decremented by 1. Then, the process returns to P8, and if the count value N after the subtraction has not reached O, it is determined that there is sales data that has not yet been printed out, and the sales data from the interrupt data memory RA7 is read out and printed.

When the count value N after the subtraction reaches ○ in P8, all the product data of the interrupting customer has been printed out, so the total amount of the interrupt from the interrupt totalizer RA3 is added to the journal 24 with the Print out. After that, the interrupt totalizer RA3 and the interrupt flag are cleared.

With the electronic cash register configured in this way, the sales data of each product purchased by the customer who interrupted and the total amount of the transaction are recorded in the journal 24 for each customer who interrupted, as shown in FIG. After the sales data and the total amount are printed out, a [discount] sign is attached to them and then printed out. Therefore, when the administrator checks the journal 24 later, it is possible to more accurately understand that there has been an interruption registration.

[Effects of the Invention] As explained above, according to the present invention, it is possible to carry out interrupt registration work for another customer during registration work for one customer. Therefore, it is possible to improve services for customers who have purchased a small number of products, and to facilitate the overall accounting operations.

In addition, in electronic cash registers with multiple display sections, one display section continues to display the sales amount or subtotal amount of the customer who interrupted the transaction, and the other display section shows the total amount of the customer who interrupted the transaction. Since the message is displayed, both the customer who was interrupted and the customer who interrupted will not feel uneasy.

Additionally, the sales data and total amount of the discount that have been registered as a discount are printed on the journal with a code indicating that it is a trade-in registration, so if you check this journal later, you will be able to see if there is a trade-in registration. You can clearly understand what happened.
