[0012]
The mode switch 5 is a switch for selecting various business modes such as “registration”, “settlement”, “setting”, and instructing the CPU 1 to execute them. Here, “registration” refers to registration processing of sales data of registered products in the memory unit when registration of sales products is performed by the product registration means, and registration of one transaction by closing registration means. In this mode, the printer 13 issues a receipt on which sales data and total data of traded products are printed. “Settlement” is a mode of business in which the contents of the memory part in which the sales data of each product is registered by the registration work are printed out from the printer 13 and then the contents of the memory part are cleared. "Is a business mode in which data necessary for executing a registration business or the like is set in the RAM 3 in advance.
[0013]
As shown in FIG. 2, the keyboard 8 has a numeric key 81 for setting the amount of goods, etc., and department codes for classifying each commodity (in this example, six departments [001] to [006]). In addition to the six preset department keys 82, the clear key 83, the multiplication key 84, the subtotal key 85, the current total key 86, etc., a foreign currency receipt key 87 for instructing the issue of a receipt in foreign currency is provided. The department key 82 constitutes product registration means, the current total key 86 constitutes part of the closing registration means, and the foreign currency receipt key 87 constitutes part of the receipt issue command means.
[0014]
FIG. 3 shows a main memory area formed in the RAM 3 of the electronic cash register in the first embodiment. In FIG. 3, reference numeral 31 denotes a transaction-specific memory that functions as a memory unit for registering sales data of registered products. is there. This transaction-specific memory 31 categorizes and accumulates the sales points and sales amounts of registered products by department code, and accumulates the total transaction points and total transaction amounts. From each item area of code, name, points, and amount Become. Each department code [001] to 006] and a code [TTL] indicating the transaction total are set in advance in the code area, and the name [DP1] to [DP6] of the corresponding department code and the transaction total are set in the name area. The name [CASH] is preset. The score area and the amount area are cleared to “0” after the settlement is completed.
[0015]
In the figure, 32 is a transaction totalizer that totals the points and amounts of products registered as one transaction (product sales transaction), and 33 is a registration flag that is set to “1” during registration of one transaction. A flag memory 34 is a registration data buffer for temporarily storing registration data including items of key code, code No., status, points, unit price, and amount. The “status” is information for identifying the status of registration data (return registration, multiplication registration, closing registration, etc.).
[0016]
In the figure, numeral 35 is a numeral register for temporarily storing numerical data set by the numeral key 81, numeral 36 is a foreign currency rate memory for storing a conversion rate of foreign currency to Japanese currency, and numeral 37 is a monetary amount at the conversion rate. Is a foreign currency receipt buffer that sequentially stores and stores receipt print data of merchandise sales data and transaction total data converted into a series of address numbers 1, 2, 3,..., 38 counts the write address number of the foreign currency receipt buffer. A write counter memory 39 is a read counter memory for counting the read address number of the foreign currency receipt buffer. Here, the foreign currency rate memory 36 constitutes a part of the conversion rate storage means, and the foreign currency receipt buffer 37 constitutes a part of the converted data storage means.
[0017]
Therefore, the electronic cash register according to the first embodiment, when the CPU 1 performs arithmetic processing based on a program in a state where the “setting” mode is selected by the mode switch 5, particularly the flowchart of FIG. The foreign currency rate setting process shown in FIG.
That is, the CPU 1 starts the foreign currency rate setting process when a code for instructing the start of the foreign currency rate setting process is input by the numeric key 81 in the “setting” mode. First, the numerical value is set as ST (step) 1. The register 35 is cleared. Next, it waits for a number to be set by the number key 81 as ST2. Each time a number is entered, the data in the number register 35 is shifted by one digit to the upper position, and then a process of storing the numerical value placed in the lowest digit vacated by this shift is executed. If the clear key 83 is input as ST3, the process returns to ST1 to temporarily clear the numeric register 35. Thereafter, if the current total key 86 is input as ST4, the data of the numeric register 35 is transferred to the foreign currency rate memory 36 and overwritten and stored as ST5. This is the end of the foreign currency rate setting process.
[0018]
In addition, the electronic cash register is a program incorporated so that the CPU 1 can execute each process shown in the flowcharts of FIGS. 5 to 7 in a state where the “registration” mode is selected by the mode switch 5. I have.
FIG. 5 is a flowchart showing the department registration process. In the “registration” mode, the CPU 1 uses the numeric key 81 to enter numerical data corresponding to the amount of money (unit price) in Japanese currency, and then the department key 82 When entered, this department registration process is started, and first, a registration flag in the flag memory 33 is checked as ST1. Here, if the registration flag is reset to “0”, it is determined that one item of merchandise sales transaction with one shopper has been registered by inputting the department key 82, and the transaction totalizer 32. And the foreign currency receipt buffer 37 is cleared. Further, the count value A of the write counter memory 38 is reset to “0”. Further, the registering flag in the flag memory 33 is set to “1”. When the registering flag is set to “1” in ST1, the above-described processing is not performed because the merchandise registration for the two or more items in the merchandise sales transaction with one shopper is performed.
[0019]
Next, as ST2, the CPU 1 stores registration data including key code, code number, status, points, unit price, and monetary amount in the registration data buffer 34, and clears the register register 35. In this case, the key code is the key code of the input department key 82, and the code No is the department code set in the department key 82. The registration score is the multiplier in the case of multiplication registration (registration in which a multiplier is input by the numeric key 81 and the multiplication key 84 before product registration), and is “1” in the case of no multiplication registration. The unit price is numerical value data stored in the numerical value register 35, and the registration amount is an amount calculated by multiplying the registration point by the unit price. The status is a value indicating that the registration is multiplication at the time of multiplication registration.
[0020]
Next, among the areas corresponding to each department code in the transaction memory 31 as ST3, the department code score area and the amount area corresponding to the code No. stored in the registration data buffer 34 are stored in the registration data buffer 34. Add the number of registered points and the registered amount. In ST4, the registration points and the registration amount are added to the transaction point area and the transaction amount area of the transaction total unit 32, respectively. Furthermore, as ST5, the department name set in the name area corresponding to the corresponding department code in the transaction memory 31 is read, and this department name and the registered amount are displayed on the operator display 10 and the customer display 11.
[0021]
Next, as ST6, the department registration details data to be printed on the receipt with the amount of Japanese currency (hereinafter referred to as Japanese currency receipt) is edited. In the case of multiplicative registration, the Japanese receipt print data of the department registration details data is edited with the registration point, unit price and registration amount data stored in the registration data buffer 34 and the department name data read from the transaction memory 31. . If it is not multiplication registration, the Japanese receipt print data of the department registration details data is edited with the registration amount data stored in the registration data buffer 34 and the department name data read from the transaction memory 31. Thereafter, in step ST7, the Japanese receipt print data of the department registration details data is sent to the printer 13 for printing on receipt paper and journal paper.
[0022]
Next, the CPU 1 converts the unit price data stored in the registration data buffer 34 as ST8 by the conversion rate set in the foreign currency rate memory 36 to convert the unit price of the registered product into the foreign currency amount (rounded down). Then, the unit price after conversion is multiplied by the number of registration points to calculate the registration amount based on the amount of foreign currency (product sales data conversion means). Then, in ST9, using the unit price and the registered amount converted into the foreign currency amount, department registration detailed data for printing on a receipt based on the foreign currency amount (hereinafter referred to as a foreign currency receipt) is edited. In the case of multiplication registration, the foreign currency receipt print data of the department registration details data is edited with the registration point, unit price, converted registration amount, and department name data. If it is not multiplication registration, the converted registration amount data and department Edit foreign currency receipt print data of department registration details data with name data. Thereafter, if the count value A of the write counter memory 38 is updated by +1 in ST10, the foreign currency receipt of the department registration detailed data edited in the process of ST9 is stored in the area corresponding to the address number A of the foreign currency receipt buffer 37 as ST11. The print data is written and saved, and this department registration process is terminated.
[0023]
FIG. 6 is a flowchart showing the closing registration process. When the current key 86 is input in the “registration” mode, the CPU 1 starts this closing registration process. First, as ST1, a registration flag in the flag memory 33 is started. Check out. Here, if the registration flag is reset to “0”, it is an erroneous operation in which the closing registration was performed before the product registration for one transaction, and therefore the input of the current total key 86 is ignored as an error.
[0024]
If the registering flag is set to “1” in ST1, registration data including key code, code number, status, score, unit price, and amount of money is stored in the registration data buffer 34 as ST2. In this case, the key code is the key code of the current total key 31, and the registration points and the registration amount are the transaction points and the transaction amount stored in the transaction total unit 32. Further, the code number and the unit price are “0”, and the status is a value indicating that the registration is closing.
[0025]
Next, as ST3, the registration points (transaction points) and the registration amount (transaction amount) stored in the registration data buffer 34 are added to the point area and the amount area of the transaction total code [TTL] in the transaction memory 31, respectively. Also, as ST4, the transaction total name [CASH] set in the name area corresponding to the transaction total code of the transaction memory 31 is read, and the transaction total name and the registered amount (transaction amount) are displayed on the operator display 10 and Display on the customer display 11.
[0026]
Next, as ST5, the closing registration details data for printing on the Japanese receipt is edited. At this time, the registration data (Japanese currency receipt printing data of the closing registration details data) is stored with the registration point (transaction points) and registration amount (transaction amount) data stored in the registration data buffer 34 and the transaction total name data read from the transaction memory 31. Edit. Thereafter, in ST6, the Japanese receipt printing data of the closing registration details data is sent to the printer 13 for printing on receipt paper and journal paper.
[0027]
Next, the CPU 1 divides the registration amount (transaction amount) data stored in the registration data buffer 34 as ST7 by the conversion rate set in the foreign currency rate memory 36, thereby rounding down the transaction amount to the amount of foreign currency (decimal place after the decimal point). ) (Transaction total data conversion means). Then, the registration details data for printing on the foreign currency receipt is edited using the transaction amount converted to the foreign currency amount as ST8. Also in this case, the foreign currency receipt print data of the closing registration details data is registered with the registration points (transaction points) stored in the registration data buffer 34, the converted transaction amount, and the transaction total name data read from the transaction memory 31. To edit. After that, if the count value A of the write counter memory 38 is updated by +1 in ST9, the foreign currency receipt of the closing registration details data edited in the process of ST8 is stored in the area corresponding to the address number A of the foreign currency receipt buffer 37 as ST10. Write and save print data.
After that, the CPU 1 sends a long receipt command to the printer 13 as ST11, and issues a Japanese currency receipt R1 (see FIG. 8) in which sales data and total data of products sold and sold in one transaction are printed in Japanese currency. If ST1 is controlled, the registration flag in the flag memory 33 is reset to "0" in ST12, and this tightening registration process is terminated.
[0028]
FIG. 7 is a flowchart showing the foreign currency receipt key process. When the foreign currency receipt key 87 is input in the “registration” mode, the CPU 1 starts this key process. Check out. Here, if the registration flag is set to “1”, it is determined that the foreign currency receipt is issued during the product registration of one transaction, and the input of the foreign currency receipt key 87 is ignored as an error. .
[0029]
When the registering flag is reset to “0” in ST1, the write counter memory 38 is checked as ST2. If the count value A is “0”, it is determined that no foreign currency receipt print data is stored in the foreign currency receipt buffer 37, and this key process is terminated without issuing a foreign currency receipt.
[0030]
If the count value A in the write counter memory 38 is larger than “0” in ST2, the count value B in the read counter memory 39 is reset to “0” in ST3. Next, if the count value B of the read counter memory 39 is updated by +1 as ST4, the count value B of the read counter memory 39 is compared with the count value A of the write counter memory 38 as ST5. Here, when the count value B is less than or equal to the count value A, since there is unprinted foreign currency receipt print data in the foreign currency receipt buffer 37, it is stored in the area of the address number B of the foreign currency receipt buffer 37 as ST6. The foreign currency receipt print data is read, and the foreign currency receipt print data is sent to the printer 13 as ST7, and printed on receipt paper and journal paper.
[0031]
Thereafter, returning to ST4, the count value B of the read counter memory 39 is updated by +1, and then compared with the count value A of the write counter memory 38. Thus, until the count value B exceeds the count value A, the process of printing out the foreign currency receipt print data receipt paper and journal paper stored in the area of the address number B of the foreign currency receipt buffer 37 is repeated. If it is confirmed in ST5 that the count value B exceeds the count value A, a long receipt command is sent to the printer 13 in ST8, and sales data and total data of products sold and sold in one transaction are obtained. The issuance of the foreign currency receipt R2 (see FIG. 8) printed with the amount of foreign currency is controlled, and this foreign currency receipt key process is terminated.
[0032]
In the electronic cash register of the first embodiment configured as described above, an arbitrary foreign currency conversion rate can be set in the foreign currency rate memory 36. That is, the foreign currency rate setting process is selected in the “setting” mode. In this state, an arbitrary foreign currency conversion rate is entered using the numeric key 81, and then the current total key 86 is pressed. By doing so, the numerical data is set in the foreign currency rate memory 36 as the foreign currency conversion rate.
[0033]
Thus, the electronic cash register of the present embodiment in which the conversion rate of the foreign currency is set registers the sales data of the product in the transaction memory 31 with the amount of the Japanese currency when the sales registration of the product is performed by operating the department key 82. After processing and registering the closing of one transaction by operating the current total key 86, a Japanese receipt R1 in which sales data and total data of the products sold and sold in that one transaction are printed in the amount of Japanese currency is issued. Yes. In addition, when the foreign currency receipt key 87 is operated after the closing registration process, the sales amount and the total amount of the commodity sold and sold in the one transaction are converted at the conversion rate set in the foreign currency rate memory 36. A foreign currency receipt R2 printed with a monetary amount is issued as a subsequent receipt.
[0034]
That is, each time a product is registered for sale by operating the department key 82, the sales amount in Japanese currency of the registered product is calculated from the number of sales of the product and the unit price of the product in Japanese currency, and the corresponding department in the transaction-specific memory 31 is calculated. It is added to the score area and the money area corresponding to the code. Further, the receipt print data of the department registration details data such as the department name, the number of sales, the unit price and the sales amount of the registered product is edited and printed on the receipt paper and the journal paper by the printer 13. Further, the unit price consisting of the amount of Japanese currency is converted into the amount of foreign currency at the conversion rate set in the foreign currency rate memory 36, and the unit price after the conversion is multiplied by the sales points to sell the foreign currency amount of the registered product. The amount is calculated. Then, the receipt print data of the department registration details data including the unit price and the sales amount consisting of the amount of the foreign currency is edited, and this receipt print data is sequentially stored in the foreign currency receipt buffer 37.
[0035]
After that, when the closing registration of one transaction is performed by operating the current total key 84, the receipt of the closing registration data including the total amount of the transaction calculated in the transaction totaling unit 32 and the total amount of the amount of Japanese currency, etc. The print data is edited and printed on receipt paper and journal paper by the printer. After that, a receipt paper long feed process is performed, and a Japanese receipt R1 in which the sales amount of the registered product and the total transaction amount are printed in the amount of the Japanese currency is issued. Further, the total amount of the transaction is converted into the amount of foreign currency at the conversion rate set in the foreign currency rate memory 36, and the receipt print data of the closing registration data including the converted transaction amount is edited. The receipt print data of the closing registration data is stored and held in the foreign currency receipt buffer 37 following the receipt print data of the department registration details data.
[0036]
Thereafter, when the foreign currency receipt key 87 is operated before starting the product registration for the next merchandise sales transaction, each receipt print data stored and held in the foreign currency receipt buffer 37 is sequentially read out and received by the printer 13. Printed on paper and journal paper. When the final receipt print data, that is, the receipt print data of the closing registration data, is printed, a long feed process is performed on the receipt paper, and the sales amount of the registered product and the total transaction amount are converted into the foreign currency amount. A printed foreign currency receipt R2 is issued.
[0037]
FIG. 8 shows one item belonging to the department code 001 with a unit price of 100 yen and two products belonging to the department code 002 with a unit price of 200 yen, with the conversion rate = 0.632 set in the foreign currency rate memory 36. A Japanese currency receipt R1 and a foreign currency receipt R2 printed and issued in the case of sales registration are shown. In the receipt print items, “YY-MM-DD” and “hh: mm” indicate the transaction date and time, “No. 01” indicates the ID number of the electronic cash register, and “# 001” indicates the cashier. An ID number is indicated, and “0001” indicates a transaction number.
[0038]
As shown in the figure, the unit price and the sales amount of the registered product and the total transaction amount are printed only in the amount of the Japanese currency on the Japanese currency receipt R1 which is always issued by executing the closing registration process, and the foreign currency receipt key 87 is operated. Since the foreign currency receipt R2 issued in this case is printed with only the amount of the foreign currency, the contents of the receipt can be easily confirmed. Further, a comment “** Receipt after foreign currency **” indicating that the foreign currency receipt R2 is a foreign currency receipt is printed. Therefore, even if there are two receipts for the same transaction, a Japanese receipt R1 and a foreign currency receipt R2, it can be easily determined that one is a foreign currency receipt, so the two receipts are for different transactions. It can prevent fraud. Further, since the conversion rate is also printed on the foreign currency receipt R2, there is an effect that the shopper can easily confirm the conversion rate.
[0039]
In addition, since the foreign currency receipt key 87 can be issued by operating the foreign currency receipt key 87 after the closing registration process for one transaction, there is a waste of issuing the foreign currency receipt R2 to the shopper who does not need the amount information in the foreign currency. In addition, it is possible to easily deal with a case where a shopper requests a payment in a foreign currency or a statement in a foreign currency after starting a merchandise sales transaction with the shopper, which is highly practical. In addition, the troublesome work of confirming whether the shopper uses a foreign currency or requires details in a foreign currency before the cashier starts a merchandise sale transaction with the shopper can be omitted.
[0040]
Further, each time a product is registered, the unit price consisting of the amount of Japanese currency of the registered product is converted into the amount of foreign currency at the conversion rate set in the foreign currency rate memory 36, and the converted unit price is multiplied by the number of sales points. Calculate the sales amount consisting of the foreign currency amount of the registered product, edit the receipt print data of the department registration details data including the unit price and the sales amount consisting of the foreign currency amount, and store this receipt print data in the foreign currency receipt buffer 37 To do. Further, when the closing registration of one transaction is performed, the total amount of the transaction is converted into the foreign currency amount set in the foreign currency rate memory 36, and the receipt print data of the closing registration data including the converted transaction amount is edited. Then, the receipt print data of the closing registration data is stored in the foreign currency receipt buffer 37. When the foreign currency receipt key 87 is input, the receipt print data stored in the foreign currency receipt buffer 37 is sequentially read after the Japanese currency receipt R1 is issued, and the foreign currency receipt R2 is printed and issued. Therefore, since the amount of the receipt print data is already converted and stored in the foreign currency amount before the issue of the foreign currency receipt is commanded, the time required for issuing the foreign currency receipt R2 can be shortened.
[0041]
By the way, when currency integration that integrates the currencies of multiple countries into one type of currency is implemented, although merchandise sales are performed in the integrated currency, many shoppers before the integration are It is considered that a transaction statement in currency is required. Moreover, most of the countries that are currency-integrated are bordered by borders, so it is necessary to be able to answer not only requests from shoppers in their own country but also requests from shoppers in other countries. For this reason, it is desirable that the conversion rate of the currency requested by the shopper can be selected from a plurality of types, not limited to one type.

Then, next, a second embodiment related to the invention described in claims 3 and 4 will be described with reference to FIGS. In the second embodiment, when the sale registration of the product is performed by the product registration means, the sale data of the product is registered in the memory unit with the amount of Japanese currency, and the closing registration of the one transaction is performed by the closing registration means. When done, an electronic cash register that issues a receipt that prints the sales data and total data of the products sold and sold in that transaction in the amount of the Japanese currency, and prints the sales amount of the registered product and the total amount of the transaction in the amount of the Japanese currency After the received receipt, a receipt printed with the sales amount and transaction total amount of the registered product converted into the foreign currency amount at the conversion rate arbitrarily selected from the four types of conversion rates can be issued selectively It is a thing.
The hardware configuration of the electronic cash register according to the second embodiment is the same as that of the electronic cash register according to the first embodiment, and a description thereof is omitted using the reference numerals in FIG.
[0043]
FIG. 9 shows the main key arrangement of the keyboard 8 in the electronic cash register of the second embodiment. In this second embodiment, the electronic cash register of the first embodiment has. In addition to the numeric key 81, the department key 82, the clear key 83, the multiplication key 84, the subtotal key 85, the current total key 86 and the foreign currency receipt key 87, numbers 1, 2, 3, and 4 for identifying four types of foreign currency respectively. Four assigned foreign currency keys 88 are provided. Here, the foreign currency key 88 constitutes a conversion rate specifying means for specifying any one conversion rate from a plurality of foreign currency conversion rates stored by the conversion rate storage means.
[0044]
FIG. 10 shows a main memory area formed in the RAM 3 of the electronic cash register in the second embodiment. This electronic cash register also has the same transaction memory 31 and total transaction as in the first embodiment. A register 32, a flag memory 33 for a registering flag, a numeric register 35, and a foreign currency rate memory 36 are provided.
Further, the electronic cash register of the second embodiment is a conversion rate storage means for storing the conversion rate of the foreign currency corresponding to the identification number of the foreign currency assigned to each of the four types of foreign currency keys 88. Conversion rate table 301, foreign currency designation memory 302 for storing a foreign currency number designated by the foreign currency key 88 as the foreign currency designation means, one transaction for each item of key code, code number, status, points, unit price, and amount Are stored and stored in order of a series of address numbers 1, 2, 3,..., A write counter memory 304 for counting the write address number of the transaction save buffer 303, and a read address of the transaction save buffer 303 It has a read counter memory 305 for counting numbers. The conversion rate table 301 includes a standard flag storage area that is set to “1” when the currency is a standard designated foreign currency, corresponding to the foreign currency identification numbers assigned to the four types of foreign currency keys 88. Has been.
[0045]
Thus, in the electronic cash register of the second embodiment, the CPU 1 can execute the foreign currency rate setting process shown in the flow chart of FIG. 10 in a state where the “setting” mode is selected by the mode switch 5. It has a built-in program.
That is, the CPU 1 starts the foreign currency rate setting process when a code for instructing the start of the foreign currency rate setting process is input by the numeric key 81 in the “setting” mode, and first clears the numeric register 35 as ST1. To do. Next, it waits for a number to be set by the number key 81 as ST2. Each time a number is entered, the data in the number register 35 is shifted by one digit to the upper position, and then a process of storing the numerical value placed in the lowest digit vacated by this shift is executed. If the clear key 83 is input as ST3, the process returns to ST1 to temporarily clear the numeric register 35. Thereafter, if one of the four foreign currency keys 88 is input as ST4, the identification number assigned to the input foreign currency key 88 is acquired, and the data of the numeric register 35 is stored as the foreign currency rate table as ST5. It is transferred to the rate area of the corresponding identification number in 301 and overwritten.
Thereafter, if the subtotal key 85 is input in ST6, the process returns to ST1. If the current total key 86 is input in ST7, the foreign currency rate setting process is terminated.
[0046]
The electronic cash register according to the second embodiment is incorporated so that the CPU 1 can execute the standard foreign currency setting process shown in the flowchart of FIG. 11 in a state where the “setting” mode is also selected. Has a program.
That is, the CPU 1 starts this standard foreign currency setting process when a numerical value is input by the numeric key 81 in the “setting” mode to command the start of the standard foreign currency setting process. Then, it waits for one of the four foreign currency keys 88 to be input. Here, when the foreign currency key 88 to which the identification number 1 is assigned as ST1 is input, the standard flag corresponding to the identification number 1 among the standard flags in the foreign currency rate table 301 is set to “1”, and the like. The standard flags corresponding to the identification numbers 2, 3, and 4 are all reset to “0”, and the standard foreign currency setting process is terminated.
When the foreign currency key 88 assigned with the identification number 2 is input as ST2, the standard flag corresponding to the identification number 2 among the standard flags in the foreign currency rate table 301 is set to "1" The standard flags corresponding to the identification numbers 1, 3, and 4 are all reset to “0”, and this standard foreign currency setting process is terminated.
Similarly, when the foreign currency key 88 assigned with the identification number 3 is input as ST3, only the standard flag corresponding to the identification number 3 is set to “1”, and the foreign currency assigned the identification number 4 as ST4. When the key 88 is input, only the standard flag corresponding to the identification number 4 is set to “1”, and this standard foreign currency setting process is terminated.
[0047]
The electronic cash register is a program incorporated so that the CPU 1 can execute each process shown in the flowcharts of FIGS. 13 to 16 in a state where the “registration” mode is selected by the mode switch 5. I have.
FIG. 13 is a flowchart showing the department registration process. In the “registration” mode, the CPU 1 sets the numerical data corresponding to the amount of money (unit price) of the product in Japanese currency using the numeric key 81 and then sets the department key 82. When entered, this department registration process is started, and first, a registration flag in the flag memory 33 is checked as ST1. Here, if the registration flag is reset to “0”, it is determined that one item of merchandise sales transaction with one shopper has been registered by inputting the department key 82, and the transaction totalizer 32. And the transaction save buffer 303 is cleared. Further, the count value A of the write counter memory 304 is reset to “0”. Further, the registering flag in the flag memory 33 is set to “1”. If the registering flag is set to “1” in ST1, it is determined that product registration for two or more items in the product sales transaction with one shopper has been performed, and the above processing is not performed.
[0048]
Next, after updating the count value A of the write counter memory 304 by +1 as ST2, the CPU 1 stores registration data including items of key code, code number, status, points, unit price, and amount of money in the transaction save buffer 303 as ST3. The data is stored in the area corresponding to the address number A, and the register register 35 is cleared. In this case, the key code is the key code of the input department key 82, and the code No is the department code set in the department key 82. The registration score is the multiplier in the case of multiplication registration, and is “1” in the case of no multiplication registration. The unit price is numerical value data stored in the numerical value register 35, and the registration amount is an amount calculated by multiplying the registration point by the unit price. The status is a value indicating that the registration is multiplication at the time of multiplication registration.
[0049]
Next, among the areas corresponding to each department code in the transaction memory 31 as ST4, the department code score area and the amount area corresponding to the code No. stored in the area corresponding to the address number A of the transaction save buffer 34 are displayed. The registration points and the registration amount stored in the area corresponding to the address number A of the transaction save buffer 34 are added. In ST5, the registration points and the registration amount are added to the transaction point area and the transaction amount area of the transaction total device 32, respectively. Further, as ST6, the department name set in the name area corresponding to the corresponding department code in the transaction memory 31 is read, and the department name and the registered amount are displayed on the operator display 10 and the customer display 11.
[0050]
Next, as ST7, the department registration details data for printing on the Japanese receipt with the amount of the Japanese currency is edited. In the case of multiplicative registration, the department registration detail data includes the registration point, unit price and registration amount data stored in the area corresponding to the address number A of the transaction save buffer 34 and the department name data read from the transaction memory 31. Edit Japanese receipt print data. If the registration is not multiplication registration, the Japanese receipt print data of the department registration details data is edited with the registration amount data and department name data. Thereafter, in step ST8, the Japanese receipt print data of the department registration details data is sent to the printer 13 and printed on receipt paper and journal paper, and the department registration processing is terminated.
[0051]
FIG. 14 is a flowchart showing the closing registration process. When the current key 86 is input in the “registration” mode, the CPU 1 starts this closing registration process. First, as ST1, a registration flag in the flag memory 33 is started. Check out. Here, if the registration flag is reset to “0”, it is determined that the closing operation has been performed before the product registration for one transaction, and the input of the current total key 86 is ignored as an error.
[0052]
If the registering flag is set to “1” in ST1, the count value A of the write counter memory 304 is updated by +1 as ST2, and then the key code, code number, status, number of points, unit price, amount of money as ST3 The registration data consisting of these items is stored in the area corresponding to the address number A of the transaction save buffer 303. In this case, the key code is the key code of the current total key 31, and the registration points and the registration amount are the transaction points and the transaction amount stored in the transaction total unit 32. Further, the code number and the unit price are “0”, and the status is a value indicating that the registration is closing.
[0053]
Next, as ST4, the registration points (transaction points) and registration amounts (transactions) stored in the area corresponding to the address number A of the transaction save buffer 34 in the point area and amount area of the transaction total code [TTL] in the transaction memory 31 Amount) Further, the transaction total name [CASH] set in the name area corresponding to the transaction total code in the transaction memory 31 is read as ST5, and the transaction total name and the registered amount (transaction amount) are displayed on the operator display 10 and Display on the customer display 11.
[0054]
Next, as ST6, the closing registration details data for printing on the Japanese receipt is edited. At this time, the number of registered points (the number of transactions) and the registered amount (the amount of transaction) stored in the area corresponding to the address number A of the transaction save buffer 34 and the transaction total name data read from the transaction memory 31 are tightened. Edit the Japanese receipt print data of the registration details data. Thereafter, in ST7, the Japanese receipt printing data of the closing registration details data is sent to the printer 13 to be printed out on a receipt paper and a journal paper.
[0055]
After that, the CPU 1 sends a long receipt command to the printer 13 as ST8, and issues a Japanese currency receipt R1 (see FIG. 8) in which sales data and total data of products sold and sold in one transaction are printed in Japanese currency amounts. If ST1 is controlled, the registration flag in the flag memory 33 is reset to "0" in ST9, and this tightening registration process is terminated.
[0056]
FIG. 7 is a flowchart showing the foreign currency key processing. When one of the four foreign currency keys 88 is input in the “registration” mode, the CPU 1 starts this key processing. Determine the identification number assigned to the key. Here, when the foreign currency key 88 to which the identification number “1” is assigned is input (YES in ST1), the identification number “1” is stored in the foreign currency designation memory 302. When the foreign currency key 88 to which the identification number “2” is assigned is input (YES in ST2), the identification number “2” is stored in the foreign currency designation memory 302. Similarly, when the foreign currency key 88 to which the identification number “3” is assigned is input (YES in ST3), the identification number “3” is stored in the foreign currency designation memory 302, and the identification number “4” is assigned. When the foreign currency key 88 is input (NO in ST3), the identification number “4” is stored in the foreign currency designation memory 302.
Thereafter, the conversion rate corresponding to the identification number stored in the foreign currency designation memory 302 is read from the foreign currency rate table 301, and this conversion rate is displayed on the operator display 10 and the customer display 11, and this foreign currency key processing is performed. finish.
[0057]
FIG. 16 is a flowchart showing the foreign currency receipt key process. When the foreign currency receipt key 87 is input in the “registration” mode, the CPU 1 starts this key process. Check out. Here, if the registration flag is set to “1”, it is determined that the foreign currency receipt is issued during the product registration of one transaction, and the input of the foreign currency receipt key 87 is ignored as an error. .
[0058]
If the registering flag is set to “1” in ST1, the write counter memory 304 is checked as ST2. Here, if the count value A is “0”, it is determined that the registration data is not stored in the transaction save buffer 37, and this key processing is terminated without issuing a foreign currency receipt.
[0059]
When the count value A of the write counter memory 304 is larger than “0” in ST2, it is determined whether or not the foreign currency identification number is stored in the foreign currency designation memory 302 in ST3. If it is stored, it is determined that conversion to a foreign currency identified by the identification number is designated, and it corresponds to the identification number stored in the foreign currency designation memory 302 from the foreign currency rate table 301 as ST4. The conversion rate is read, and this conversion rate is stored in the foreign currency rate memory 36. On the other hand, when the identification number is not stored in the foreign currency designation memory 302, it is determined that conversion to the foreign currency preset as the standard foreign currency is designated, and the standard flag is set from the foreign currency rate table 301 as ST5. The conversion rate corresponding to the identification number set to “1” is read, and this conversion rate is stored in the foreign currency rate memory 36.
[0060]
Next, the count value B of the read counter memory 39 is reset to “0” as ST6. Next, if the count value B of the read counter memory 39 is updated by +1 as ST7, the count value B of the read counter memory 39 is compared with the count value A of the write counter memory 38 as ST8. Here, when the count value B is less than or equal to the count value A, there is unprocessed registration data in the transaction save buffer 303. Therefore, the registration data stored in the address number B area of the transaction save buffer 303 as ST9. Read out. Then, as ST 10, the amount data in the registration data (unit price and registration amount in the case of department registration details data, transaction total amount in the case of closing registration data) is divided by the conversion rate set in the foreign currency rate memory 36. Is converted into a foreign currency amount (truncated after the decimal point) (amount data conversion means). Thereafter, the printing data on the foreign currency receipt is edited in the same manner as in the case of the Japanese currency receipt using the data converted into the amount of the foreign currency as ST11, and the printing data is sent to the printer 13 as ST12. Print output on receipt paper and journal paper.
[0061]
Thereafter, returning to ST7, the count value B of the read counter memory 304 is updated by +1, and then compared with the count value A of the write counter memory 303. Thus, until the count value B exceeds the count value A, the registration data stored in the area of the address number B of the transaction save buffer 303 is sequentially read, and the amount data in the registration data is stored in the foreign currency rate memory 36. After the conversion at the conversion rate, the process of editing the print data for foreign currency receipt and printing it on receipt paper and journal paper is repeated. If it is confirmed in ST8 that the count value B exceeds the count value A, a long receipt command is sent to the printer 13 in ST13, and the sales data and total data of the products sold and sold in one transaction are obtained. Control issuance of a foreign currency receipt R2 (see FIG. 8) printed with the amount of foreign currency. After that, in ST14, the foreign currency rate memory 36 and the foreign currency designation memory 302 are cleared, and when the conversion rate corresponding to the identification number in the foreign currency designation memory 302 is displayed on each display 10, 11, the display is erased. This foreign currency receipt key process is terminated.
[0062]
In the electronic cash register of the second embodiment configured as described above, one transaction is selected when an arbitrary foreign currency conversion rate is selected from the four types of foreign currency conversion rates set in the foreign currency rate table 301. The sales data and total data of the products sold and sold in (1) are converted into the foreign currency amount at the selected conversion rate, and the foreign currency receipt R2 on which the converted amount is printed is issued as a subsequent receipt.
[0063]
That is, each time sales registration of a product is performed by operating the department key 82, department registration details data such as a department code, the number of sales points, a unit price including the amount of Japanese currency, and a sales price are sequentially saved in the transaction save memory 303. Next, when the closing registration of one transaction is performed by operating the current total key 84, the closing registration data including the total amount of the transaction and the total amount including the amount of Japanese currency calculated by the transaction totaling device 32 is stored in the transaction. Saved in the save buffer 303. In addition, a Japanese receipt R1 in which the sales amount of the registered product and the total transaction amount are printed in Japanese currency is issued.
[0064]
After that, when the foreign currency receipt key 87 is operated before the product registration for the next product sales transaction is started, the respective registration data stored and held in the transaction save buffer 303 are sequentially read out. After the Japanese currency amount data is converted into foreign currency amount data at the conversion rate stored in the foreign currency rate memory 36, it is printed on a receipt sheet by the printer 13 and issued as a foreign currency receipt R2.
[0065]
In this case, in the foreign currency rate memory 36, when any one foreign currency is designated by the foreign currency key 88 before the foreign currency receipt key 87 is input, the conversion rate of the foreign currency is stored. , A foreign currency conversion rate preset as a standard foreign currency (standard flag = 1) is stored.
[0066]
Therefore, in the second embodiment, since the foreign currency receipt R2 can be issued by inputting the foreign currency receipt key 87, the same effects as those of the first embodiment can be obtained. There is an advantage that the foreign currency receipt R2 can be issued by selecting the currency conversion rate requested by the shopper from the foreign currency. The foreign currency receipt R2 is also printed with a comment indicating that it is a foreign currency receipt, as in the first embodiment.
[0067]
In addition, since one type out of a plurality of types of foreign currencies is set as a standard foreign currency and the foreign currency requested by the shopper is the standard foreign currency, the operation of specifying the foreign currency is not necessary, so that the operability can be improved.
In the second embodiment, the standard foreign currency can be arbitrarily set by executing the standard foreign currency setting process. However, the standard foreign currency may be fixed. Further, the effect of the present invention can be achieved without setting a standard foreign currency.
Needless to say, in this second embodiment, the types of foreign currency are not limited to four.
[0068]
【The invention's effect】
  As detailed aboveThe present inventionAccording to a second currency whose rate is different from the first currency such as Japanese currency that is distributed as general currency from the shopper after starting a product sale transaction with the shopper Even if payment or a statement in the second currency is requested, it can be easily dealt with by issuing a receipt of the amount in the second currency, and a receipt that is easy to confirm regardless of whether there is such a request We can provide a product sales registration data processing device that can always be issuedThe
