Abstract

PURPOSE:To simplify correcting operation and check correcting function, by performing subtraction and addition correcting processing by - and + keys for correction when there is change in dealings. CONSTITUTION:When the amount of sales is inputted by pressing ten keys on a keyboard 2, flag FN is set to ''1'' (step 25). Under this condition, if cash transaction is changed to ticket transaction or ticket transaction is changed to cash transaction by some reason, an operator depresses a correction - key or a correction + key. Flag FCOR - or flag FCOR + is set to ''1''. When a cash key or a ticket key is depressed, setting state of above-mentioned flags is judged by CPU14 and addition or subtraction processing is performed. If the value of corrected amount register is ''0'', it is recognized that correction is performed normally, and correction is completed.

Description

[Detailed Description of the Invention] (A) Main Features of the Invention In addition to registering the amount and number of items in the product department, the invention also enables transactions such as cash transactions, □ credit transactions, and cash voucher transactions.
It relates to an electronic cash register that has the function of totaling the amount and number of transactions for each transaction.

(b) Background of the Invention In addition to cash transactions, the recent electronic cash V-Jinuta has many transaction keys such as ticket vending keys and credit keys. Normally, the operator looks at the products purchased by the customer, registers the products, presses the transaction key in accordance with the customer's desired payment, issues a cash register, and completes the transaction process.

However, after the above-mentioned transaction processing is 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 make corrections by manually calculating the amount and number of transactions for each type of transaction in the settlement report after closing or at the time of settlement. The other is a process in which 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, and re-register by looking at the receipt before the transaction was changed. It is.

However, the latter process may require many key operations,
There are many cases where the former process is adopted as it is not realistic.

In this case, due to loss of memos and errors in manual calculations, corrections are unreliable and the correct amount and number of transactions cannot often be ascertained.

(c) Purpose of the Invention Therefore, the present invention provides an electronic cash register which has the function of easily correcting changes in transactions as described above, and also reliably correcting aggregated data. Provided for all purposes.

B) Effect of the Invention According to this invention, when a transaction is changed, the correction key subtracts all data for the transaction from the transaction aggregate data before the change, and the correction key subtracts the entire transaction data from the transaction aggregate data after the change. Since the data for that transaction is added to the key, the key correction operation is to correct the transaction type, and there is no correction input operation for the product department or the amount of that department, so the correction operation is easy. Furthermore, since the balance between the subtracted data and the added data is checked, transactions can be corrected accurately and the reliability of the aggregated data can be improved.

Naka) Explanation of examples An embodiment of the present invention will be described in detail below based on the drawings.

The drawing shows all the electronic gear registers, and in FIG. We are prepared.

FIG. 2 shows the above-mentioned keyboard 2, and the mode changeover switch 6 can be set to power off, registration mode,
Modes such as inspection mode, payment mode, preset mode, batch correction mode, etc. are switched, the department key 7 is used to input the product department, the numeric keypad 8 is used to input the amount of the product, and the subtotal key 9 is used to input the subtotal of registration.

The ticket sales key 10 and the cash key 11 are transaction keys for transaction types, and the ticket sales key 1O is input when the transaction is a cash voucher, and the cash key 11 is input when the transaction is cash.

Correction key 12 and correction key 18 are keys for correcting the aggregated data of each transaction when the transaction type is changed from cash to ticket sales or vice versa.
2 subtracts data, and correction + key 13 adds data.

FIG. 8 shows a control circuit, in which the CPU 14 controls each circuit device according to the control program stored in the ROM 15,
The keyboard 2 performs input operations using the various keys described above, the display 8 displays the entered amount, and the printer 5 prints registration data, subtotal data, transaction data, etc. on paper and issues a receipt 4.

The RAM 16 writes and reads necessary data,
Area R1 is a number register that stores the number data entered using the numeric keypad 8, and area R2 is a correction amount register that stores the amount when the transaction amount is corrected. Area R8 is a number flag FM, which is set when a number is entered, area R4 is a correction flag FCOR, which is set when the correction key 12 is input, and area R5 is a flag FM. Correction ten flag F
COR+, and the flag is set when the corrector key 1B is input.

Areas R6 to RIO 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, and area R
11, 'R12 stores the amount and number of cash transactions, and areas R18 and R14 store the amount and number of ticket sales transactions.

In the electronic cash register I configured as described above, a normal registration operation is performed by setting the mode changeover switch 6 to the registration mode. 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 entering the department key 7f. The number 1 is added and stored, and the input amount is displayed on the display 8.

Then, such an input operation is performed for each purchased product, and then when the cash key 11 is pressed for a cash transaction or the ticket sales key 10 is pressed for a ticket sales transaction, the printer 5 inputs the transaction data. Print and issue all 4 receipts to complete the transaction process.

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 Corrector key 1B "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.

In step 21, the CPU 14 controls the RAM 16 to clear the corrected amount register in area R2, and in step 22, the key is manually operated! If all 7 are determined, it is determined in step 23 whether it is numeric keypad 8, and if it is input by numeric keypad 8,
In step 24, the numeric data is stored in the numeric register in area R1 of the RAM 16, and in step 25, a numeric flag is set in area R8, and the process returns to step 22.

When it is determined in step 26 that the 0PU 14 is corrected - the input of the key 12, the RAM 16 is controlled in step 27,
Set the correction flag FCOR-t” in area R4,
The process returns to step 22, and when it is determined in step 28 that the corrector key 13 has been input, in step 29 the RAM is
The corrector flag F(, OR+t- is set in the area R5 of No. 16, and the process returns to step 22.

In step 30, the CPU 14 determines whether the cash key 11 is input.
Read area R4 of 15 and correct correction flag F COR
It is determined whether - has been set, and if this is determined, the area R8 of the RAM 16 is read out in step 82, and it is determined whether the numeric flag FN is set.

When the above-mentioned flag PM is determined, it is determined that there is an input 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.

Further, the above-mentioned correction process is a process of subtracting the data for the transaction from the aggregate data of cash transactions, and in step B8, the CPU 14 reads out the cash amount in area R11 of the RAM 16, and reads out the cash amount in area R11 of the RAM 16. Subtract the entire amount stored in the number register and store it again, read out the number of 9 cash lights in area R12 in step 34, subtract 91 transactions and store it again, step 85
Read the amount value of the corrected amount register in area R2,
From this, subtract the monetary value stored in the number register of area R1.

Note that when the value of the correction amount V register in area R2 is zero, the above-mentioned subtraction is performed by storing the value of the numeric register in area R1 as a negative value of 0.
If Fug FCOR- is not determined, CPtT
14 reads out area R5 of the RAM 16 in step 36 to determine whether the corrector flag FCOR+ is set.

If the above flag is not determined, the process is executed as normal processing (for example, registration processing), but the flag FC
If OR+ is determined, 0PUI4 is R at step 87.
Area lR8'i of AM16 appears one after another, negative number flag FN
is set.

If the above-mentioned flag FN is not determined, it is treated as an error and appropriate error processing is performed, and when 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 process is a process of adding data for the other transaction to the aggregate data of the cash transaction.

In other words, C! In step 88, the PU 14 reads out the cash amount in area R11 of the RAM 16, adds the entire amount stored in the number register in area R1 to this, stores it again, and in step 89 reads out the cash amount in area R1''2. Read out the WI, add one transaction to it, and store it again.In step 40, read out the amount value in the corrected amount register in area R2, and add to this the amount value stored in the number register in area R1. Add and store 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 80 described above, the CPU 14 determines whether the input of the ticket vending key IO is made in step 41. If this determination is not made, the entire process is performed as normal processing (for example, registration processing). Execute, but
When it is determined that the ticket vending key 100 has been input, the C button is pressed in step 42.
PUI 4 reads area R4=i of RAM 16 and determines whether correction flag FCOR- is set.
When this is determined, in step 48, area R8i of the RAM 16 is read out, and it is determined whether the negative number flag FN is set.

If the flag FN mentioned above is not determined, it is determined as an error and all appropriate determination 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, in step 44, the CPU 14 reads out the ticket sales amount in the area RIB of the RAM 16, and stores it in the area R.
The amount value stored in the number register 1 is subtracted and stored again, the number of tickets sold in area R14 is read out in step 45, the number of tickets sold is subtracted and the value is stored again in step 46, and the value is stored again in area R2. The amount value of the corrected amount register is read out, and the amount value stored in the number register of the area R1 is subtracted from this value.

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 is set, the CP-U 14 sets the RA in step 47.
M16 area R5t-read, correction + flag FCOR
Determine whether + is set.

If the above-mentioned flag is not determined, the process is executed as normal processing, but if the flag FCOR+ is determined, the CPU 14 reads area R8 of the ζRAM 16 in step 48 and checks whether the numeric flag FN is set. judge.

If the above-mentioned flag FN is not determined, the factory performs appropriate error processing, and if the flag FN is determined, it is determined that the input is to be corrected from another transaction (in this case, a cash transaction) to a ticket sales transaction. This correction process is a process of adding data for other transactions to the aggregated data of ticket sales transactions.

That is, in step 49, the CPU 14 reads out the ticket sales amount in area R1B of the RAM 16, and stores it in area R.
The stored amount value is added to the number register 1 and stored again, and in step 50, the number of tickets sold in area R14 is read out, 1 transaction is added thereto and stored again, and in step 51, the number of tickets sold in area R14 is read out, and the value is stored again. The corrected amount value V7- 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 step among the aforementioned steps 85, 40, 46.51 is completed, in step 52, CP, U, 1.
Step 4 clears the flags in areas R3 to R5 of the RAM 16, and in step 58 reads the amount value stored in the corrected amount register in area R2 of the RAM 16, and determines whether it is zero.

When changing a transaction, as in the example above, all aggregated data is subtracted from the transaction before the change, and then added to the aggregated data of the transaction after the change, so in the correction process before the change, the transaction is changed from cash transaction to ticket sales transaction. , step 85 ends;
In the case of the opposite change, step 46 has ended.

Therefore, since a negative amount value is stored in the correction amount register, zero is not determined in step 58, and the process returns to step 22.

Furthermore, in the correction process after a transaction change, in the case of changing from a cash transaction to a ticket sales transaction, step 85 and step 51 are completed, and in the case of the reverse change, step 46 and step 40 are completed.

Therefore, the correction amount register becomes zero when the correction processing is performed normally, and the judgment in step 58 is whether the subtraction amount and the addition amount are balanced, that is, whether the correction has been made normally, and fr, shi, zero. By being
It is assumed that the correction process has been carried out normally, and the correction process is terminated.
