Description

[Detailed description of the invention]

(b) Industrial Application Fields This invention is applicable to multiple transactions such as cash transactions, credit transactions, and gift certificate transactions, in addition to registering amounts and quantities in product departments. This invention relates to an electronic cash register that has the function of counting amounts and counts. (B) Prior Art Recent electronic cash registers have many transaction keys available as transaction keys, such as a ticket vending key and a credit key, in addition to cash transaction keys. Usually, the operator looks at the customer's purchased products and
The product is registered, the transaction key is pressed in accordance with the customer's desired payment, a receipt is issued, and the transaction process is completed. However, after the above-described transaction process has been completed, the customer often changes his or her mind and changes the payment method, for example, from a cash transaction to a ticket sales transaction, or vice versa. Operators handled this change in one of two ways. One way is to make a note of changes in transactions, and then manually correct the amounts and number of transactions for each type of transaction in the settlement report after closing or at the time of settlement. Another is that electronic cash registers with a bulk correction function create a receipt corresponding to the transaction that was changed in front of the customer, then switch to bulk correction mode, look at the receipt before the transaction was changed, and then This is a re-registration process. However, the latter process may require many key operations and is not practical, so the former process is often adopted. In this case, the reliability of corrections is low due to loss of memos and errors in manual calculations, and there are disadvantages in that it is often impossible to ascertain the correct amount and number of transactions. In addition, if you make a mistake in entering the transaction type (such as payment in cash, voucher, or credit card) after registering product sales data, as a way to correct this, you can cancel all input of the transaction type and re-enter the transaction type. There are things that need to be done anew (for example, JP-A-57-
Publication No. 771). However, according to this method, all transaction items are canceled, so if there are multiple transaction items, the successfully input transaction items are also canceled and all input operations for the transaction items are performed again. This has the problem that it requires two steps and the calculation process is complicated. (C) Problems to be Solved by the Invention As described above, this invention allows for easy correction processing by correcting only the changed transaction when a change occurs in the transaction. The purpose of the present invention is to provide an electronic cash register having a function of checking corrections and reliably correcting tabulated data. (d) Means for Solving the Problems This invention provides an amount input means for inputting a transaction amount, a plurality of transaction type input means for inputting a transaction type, and a method for inputting each transaction amount corresponding to each of these transaction type input means. and a storage means for storing aggregated data of the number of transactions, and controls the totalization of the transaction amount and number of transactions in the storage means corresponding to the transaction for each operation of the transaction type input means. a correction+ key and a correction-key for correcting the aggregated data of each transaction into additions and subtractions; Add aggregated data for specified transaction items in the storage means.
The present invention is characterized in that the electronic cash register is provided with a control means that performs correction processing by subtraction processing and also determines whether the added data and subtracted data in the addition/subtraction processing match. (e) Effect: According to the electronic cash register of the present invention, the control means controls the subtraction side to be changed based on inputs from the correction + key, correction - key, amount input means, and transaction type input means. The corrected aggregated data is subtracted from the transaction type, and the corrected aggregated data is added to the transaction type on the addition side, and the aggregated data of the corresponding transaction type in the storage means is corrected. It is determined whether the addition data and the subtraction data in the subtraction process match or not, and whether the correction process is correct or not is determined. (F) Effect of the invention According to this invention, when a transaction is changed,
The correction key is used to subtract the transaction aggregate data from the transaction aggregate data before the change (subtraction side aggregate data), and the correction + key is used to subtract the transaction aggregate data from the transaction aggregate data after the change (addition side aggregate data). Since the data is added, the key correction operation is a correction input operation only for the transaction type that has been changed, and it is necessary to redo the aggregated data for transactions that have not been changed and have been entered correctly, or for other product departments or other items. Since there is no correction input operation for departmental amounts, etc., correction operations are simplified, and calculation processing is also simplified by only processing the transactions that have been changed. Since the transaction is checked to see if the correction process has been carried out normally, the transaction can be corrected accurately and the reliability of the aggregated data can be improved. (g) Embodiment An embodiment of the present invention will be described in detail below based on the drawings. The drawing shows an electronic cash register, and in FIG. 1, a register 1 includes a keyboard 2 for inputting transaction type, department, etc., a display 3 for displaying the entered amount, and a printer 5 for issuing a receipt 4.
It is equipped with FIG. 2 shows the above-mentioned keyboard 2, and the mode changeover switch 6 is used to switch modes such as power off, registration mode, inspection mode, payment mode, preset mode, batch correction mode, etc. by pressing a predetermined key. Key 7 is used to input the product department, numeric keypad 8 is used to input the price of the product, and subtotal key 9 is used to input the registered subtotal. The ticket vending key 10 and the cash key 11 are transaction keys for transaction types, and the ticket vending key 10 is input when the transaction is a cash voucher, and the cash key 11 is input when the transaction is cash. The correction key 12 and correction key 13 are keys for correcting the total data of each transaction when the transaction type is changed from cash to ticket sales or vice versa. The correction + key 13 adds data. Figure 3 shows the control circuit, where the CPU 14 is the ROM 1
The keyboard 2 performs input operations using the various keys described above, the display 3 displays the entered amount, and the printer 5 prints the registered data on paper, Subtotal data, transaction data, etc. are printed and a receipt 4 is issued. RAM 16 writes and reads necessary data, area R1 is a number register and stores the number data entered with the numeric keypad 8, area R2 is a correction amount register and corrects the transaction amount. When that amount is stored. Area R
3 is a number flag FN, which is set when a number is set, and area R4 is a correction flag.
It is FCOR- and a flag is set when the correction-key 12 is input, and the area R5 is a correction+ flag FCOR+ and the flag is set when the correction+ key 13 is input. Areas R6 to R10 are department registration areas, and each department area includes an amount area and a number area, and the amount and number of items for the input product department are stored. Areas R11 to R14 are aggregation areas,
Areas R11 and R12 store the amount and number of cash transactions, and areas R13 and R14 store the amount and number of ticket sales transactions. In the electronic cash register 1 configured as described above, in normal registration, the mode changeover switch 6 is set to the registration mode and the registration operation is performed. In this operation, the registration of one product can be entered by inputting the amount of the product using the numeric keypad 8 and then inputting the department key 7, and the data is the amount entered in areas R6 to R10 corresponding to the product department of the RAM 16. and the number 1 are added and stored, and the input amount is displayed on the display 3. Then, such an input operation is performed for each purchased product, and then the cash key 11 is pressed in the case of a cash transaction, or the ticket sales key 10 is pressed in the case of a ticket sales transaction, and the printer 5 inputs the transaction data. The transaction process is completed by printing and issuing a receipt 4. Note that the above-mentioned registration operation is a normal operation. For example, if a cash transaction of 10,000 yen is changed to a ticket sales transaction of 10,000 yen, the aggregated data is corrected by the following operation. Correction - key 12 "10000" numeric keypad 8 Cash key 11 Correction + key 13 "10000" numeric keypad 8 Ticket sales key 10 Note that when a ticket sales transaction is changed to a cash transaction, the above-mentioned operation is performed in reverse. That is, the operations of the cash key 11 and the ticket vending key 10 are performed in reverse. The above correction operation will be explained with reference to FIG. At step 21, the CPU 14 controls the RAM 16 to clear the correction amount register in area R2, and when it determines that there is a key input at step 22, the CPU 14 controls the RAM 16 to clear the correction amount register in area R2.
If the input is from the numeric keypad 8, in step 24, the area R of RAM 16 is
Store the numeral data in the numeral register 1, set the numeral flag in area R3 at step 25,
Return to step 22. When the CPU 14 determines that the correction key 12 has been input in step 26, it controls the RAM 16 in step 27, sets the correction flag FCOR- in area R4, returns to step 22, and presses the correction key 12 in step 28. 13 is determined, in step 29 the correction + flag is stored in area R5 of RAM 16.
Set FCOR+ and return to step 22. At step 30, the CPU 14 determines whether the cash key 11 has been input, and when this is determined, the step
31, read out area R4 of RAM16 and make corrections.
Determine whether flag FCOR- is set,
When this is determined, the area R3 of the RAM 16 is read out in step 32, and it is determined whether the numeric flag FN is set. When the flag FN described above is determined, it is determined that the input is to correct the cash transaction to another transaction (in this case, a ticket sales transaction). If flag FN is not set, it is determined as an error and appropriate error processing is performed. In addition, the above-mentioned correction process is a process of subtracting the data of the transaction from the aggregate data of cash transactions,
At step 33, the CPU 14 accesses area R1 of RAM 16.
Read out the cash selling amount of 1, and from this, area R
The amount stored in the number register 1 is subtracted and stored again, the cash sales quantity of area R12 is read out in step 34, one transaction is subtracted from this and stored again, and the value of area R2 is stored in step 35. The amount value in the corrected amount register is read out, and the amount value stored in the number register in area R1 is subtracted from it. Note that when the value of the correction amount register in area R2 is zero, the above-mentioned subtraction is stored with the value of the number register in area R1 as a negative value. If the correction flag FCOR- is not determined in step 31 described above, the CPU 14 executes step 31.
36 reads area R5 of RAM16 and corrects +
Determine whether flag FCOR+ is set. If the above flag is not determined, the process is executed as normal processing (for example, registration processing), but
When correction + flag FCOR + is determined, CPU1
4, in step 37, the area R3 of the RAM 16 is read out to determine whether the number flag FN is set. If the flag FN mentioned above is not determined, it is treated as an error and appropriate error processing is performed. If the flag FN is determined, it is determined that the input is to be corrected from another transaction (in this case, a ticket sales transaction) to a cash transaction, and this correction is made. The process is a process of adding data for other transactions to the aggregate data of cash transactions. That is, the CPU 14 uses the RAM 16 in step 38.
Read out the cash sales amount in area R11, add the amount value stored in the number register in area R1 to this and store it again, read out the cash sales amount in area R12 in step 39, and add one transaction to this. Then, in step 40, the amount value in the corrected amount register in area R2 is read out, and the amount value stored in the number register in area R1 is added thereto and stored again. Note that when the value of the correction amount register in area R2 is a negative value, the above-mentioned addition ends up being a subtraction process. If the input of the cash key 11 is not determined in step 30 described above, the CPU 14 determines whether the input of the ticket vending key 10 is made in step 41. If this determination is not made, the process is carried out as normal processing (for example, registration processing). However, when it is determined that the ticket vending key 10 has been input, the CPU 14 loads the RAM 16 in step 42.
Read area R4 and correct - flag FCOR -
It is determined whether the numeral flag FN is set, and if this is determined, the area R3 of the RAM 16 is read out in step 43, and it is determined whether the numeral flag FN is set. If the flag FN mentioned above is not determined, it is determined as an error and appropriate error processing is performed, but if the flag FN is determined, it is determined that the input is to correct the ticket sales transaction to another transaction (in this case, a cash transaction). However, in the correction process, data for that transaction is subtracted from the aggregated data of ticket sales transactions. That is, the CPU 14 at step 44
The amount of tickets sold in area R13 in step 6 is read out, and the amount stored in the number register of area R1 is subtracted from this and stored again.In step 45, the number of tickets sold in area R14 is read out, and from this, 1
The transaction amount is subtracted and stored again, and in step 46, the amount value in the corrected amount register in area R2 is read out, and the amount value stored in the number register in area R1 is subtracted from this. Note that when the value of the correction amount register in area R2 is zero, the above-mentioned subtraction is stored with the value of the number register in area R1 as a negative value. If it is not determined in step 42 that the correction flag FCOR- has been set, the CPU 14 reads out area R5 of the RAM 16 in step 47.
Determine whether correction+flag FCOR+ is set. If the above flags are not determined, the process is executed as normal, but correction + flag
When FCOR+ is determined, the CPU 14 executes the step
At step 48, area R3 of the RAM 16 is read to determine whether the number flag FN is set. If the flag FN mentioned above is not determined, it is treated as an error and appropriate error processing is performed. If the flag FN is determined, it is determined that the input is to be corrected from another transaction (cash transaction in this case) to a ticket sales transaction, and this correction is made. The processing is a process of adding data for other transactions to the aggregated data of ticket sales transactions. In other words, the CPU 14 uses the RAM 16 in step 49.
The amount of tickets sold in area R13 is read out, and the amount value stored in the number register of area R1 is added to this and stored again.In step 50, the number of tickets sold in area R14 is read out, and one transaction is added to this. Then, in step 51, the amount value in the corrected amount register in area R2 is read out, and the amount value stored in the number register in area R1 is added thereto and stored again. Note that when the value of the correction amount register in area R2 is a negative value, the above-mentioned addition ends up being a subtraction process. When one of the aforementioned steps 35, 40, 46, and 51 is completed, the CPU 14 starts running at step 52.
The flags in areas R3 to R5 of the RAM 16 are cleared, and in step 53, the amount value stored in the corrected amount register in the area R2 of the RAM 16 is read out to determine whether it is zero. When changing a transaction, as in the example above, the aggregated data is subtracted from the transaction before the change, and then added to the aggregated data of the transaction after the change. Therefore, in the correction process before the change, the change from cash transaction to ticket sales transaction is subtracted from the transaction before the change. In the case of a change, step 35 has been completed; in the case of a reverse change, step 46 has been completed. Therefore, since a negative amount value is stored in the corrected amount register, zero is not determined in step 53, and the process returns to step 22. Furthermore, in the correction process after a transaction is changed, if the change is from a cash transaction to a ticket sales transaction, step 35 and step 35 are performed.
51 has been completed, and in the case of the reverse change, step 46 and step 40 have been completed. Therefore, the correction amount register becomes zero when the correction processing is normally performed. Therefore, the judgment in step 53 is a comparison judgment of whether the subtraction amount and the addition amount match or do not match. It is determined whether or not the amount has been corrected, and by determining zero as described above, it is determined that the two amounts match, and the correction process is terminated, assuming that the correction process has been successfully performed.
