Description

[Detailed Description of the Invention] (Industrial Application Field) The present invention is applicable to a cash register having an external memory, such as a magnetic recording cassette tape, when correcting or canceling a registration due to a mistyped receipt or a return. This relates to a processing method.

(Prior art) In cash register machines that sequentially record registration data in external memory, once the data written to external memory is modified or canceled on the spot, the operation becomes extremely difficult. This is complicated and can easily lead to operator errors.
Previously, receipts that required registration cancellation were kept, and at the end of the day, the registration data to be corrected was entered sequentially by key input while looking at the receipts (for example, JP-A-55-39959). issue).

However, with the conventional method described above, when there is a large number of individual sales data entered on a single receipt, all of this information must be entered using the keypad, which requires a great deal of effort and is prone to errors. It had the disadvantage of being easy.

(Problems to be Solved by the Invention) The present invention was made with the purpose of simplifying the conventional registration cancellation method as described above and reducing the labor of the operator. This is intended to eliminate the waste of inputting data redundantly when canceling and registering data.

(Means for solving the problem) The cash receiving function is equipped with a keyboard, function keys, receipt issuing means, internal memory, external memory, etc. A receipt is issued from the printer after the total is processed by pressing the keys on the Yonkey, and the sales amount and quantity for each product are accumulated in the internal memory, and the registered data group that corresponds one-to-one with each receipt is sequentially stored with the same number as the receipt. In a cash register that records sequentially on an external memory such as a cassette tape or a diskette, at the time of registration, the registered data is accumulated in the internal memory regardless of whether it is correct or not, whether it is canceled or not, and The above registered data is stored and retained in the above external memory in correspondence with the receipt number, and when modifying the registration, after canceling with the above function key, by inputting the receipt number, the above input data is stored from the above external memory. The data corresponding to the receipt number is read out, the same data is subtracted from the accumulated data in the internal memory, and the data corresponding to the receipt number in the external memory is invalidated.

(Function) At the time of registration, that is, when performing sales processing to a customer, the registered data (product unit price for each product x number of items) is input into the internal memory and external memory as correct data regardless of correctness or cancellation. Issue a receipt. Even if there is an input error or cancellation, the input data will be retained as is. In the event of an incorrect input, the correct input is of course made, and receipts for incorrectly entered or canceled sales are not given to the customer, so they remain in the hands of the operator. Registration corrections can be made at any time later, but if you input the receipt number after canceling with the function key, the data corresponding to the receipt number will be read from the external memory and subtracted from the total in the internal memory. Therefore, the sales amount corresponding to that receipt will be reduced from the cumulative result in the internal memory. The device is designed to operate in this way, so when entering the receipt number above, if you first enter the number of the receipt that was incorrectly entered or the purchase was canceled, the total data in the internal memory will be corrected. That will happen. When making immediate corrections, all you have to do is enter the receipt number, and there is no need to enter the specific product, correction amount, etc. At this time, the data corresponding to the receipt number is invalidated in the external memory, so the correction operation is completed. As invalidation processing, the data may be erased, but it is also possible to simply mark the data as invalid. To input the above-mentioned receipt number, the operator can enter the number of the receipt that he did not give to the customer but left in his hand.
Basically, any means for retaining receipt numbers that have been entered incorrectly or canceled is arbitrary.

(Example) The present invention will be explained below using examples. FIG. 1a is a schematic block diagram of a cash register used in the system of the present invention, and FIG. 1b is a key arrangement diagram of the same keyboard. In figure a, the CPU is a microprocessor,
RAM is internal memory, and ROM is read-only memory that stores programs. In figure b,
Reference numeral 1 designates a key socket for switching operation modes, into which a specific key is inserted and turned.In the normal money acceptance mode, the key socket is turned to the REG scale position. 2 is a numeric keypad used for inputting numerical data. 3 is a group of keys for inputting product codes, DP1,
DP2...One product corresponds to one key of DPn. 4 is a group of function keys, ST is a subtotal key for transferring input data from the number area of the internal memory to a predetermined work area, and CASH is used to finish a series of key inputs and continue the program to the CPU. cash acceptance key for
VOIP is a function key for cancel registration.

In normal sales registration, after the required number of individual sales data such as product code, quantity, amount, etc. are entered using keys, the data of the specified items is output to the printer by key operation of the cash acceptance key CASH and a receipt is issued. At the same time, as will be described later, the total sales quantity and total sales amount are added for each product in the internal memory RAM, and at the same time, registration data corresponding one-to-one with each receipt is stored in the external memory (magnetic memory in this example). cassette tape). Figure 2a shows the format of normal registration data on external memory, in which there is a valid mark before the sales data, a receipt number, and which machine among the multiple cash registers. The machine number and date indicating whether the product was used are recorded, and the required number of individual sales data including product code, quantity, and price are recorded as sales data, as shown in FIG. Normal registration data having such a configuration is sequentially recorded in the external memory in the number of customers processed by the machine in one day.
Figure 3a shows the memory allocation of the internal memory RAM, and the product-specific accumulation area includes each product code DPi and the total sales amount for each product, as shown in Figure 3b.
TTLi, total sales quantity CNTi, and unit price of each product are memorized and updated each time a receipt is issued.
TTL and CNT are cumulatively updated.

If a purchase is canceled, a product is changed, etc. during normal registration, enter the incorrect data as is, create a receipt, issue a new correct receipt, and keep the incorrect invalid receipt, or Make a note of the receipt number, and after the day's sales work is finished, cancel the registration while looking at the stored receipt or the memo with the receipt number written in it.

Figure 4 shows the key operation procedure for canceling registration. First, press the function key VOID for canceling registration.
, then the numeric keypad and subtotal keys.
When you enter the number of the required number of receipts (5 in this example) using ST, the internal memory
The receipt number is memorized in the receipt number work area in the RAM, and when the cash acceptance key CASH is finally operated, the cassette tape (hereinafter abbreviated as CMT) is rewound once and the entire tape is stored on the CMT without distinction between valid and invalid. The first registered data #1 among the normal registered data groups #1, #2, ... #n that are recorded as valid is first read out to the read data store area in the internal memory, and the receipt number in the registered data is read out. It is sequentially compared with the receipt number group (5 in Figure 5) stored in the receipt number work area, and if there is no same number, the next registered data #2 is read from the CMT and read data store area in the internal memory. The contents of will be rewritten to the following registered data. The receipt number of the registered data read out sequentially in this way is searched from the five receipt numbers in the receipt number work area of the RAM, and in the example of FIG. 5, when the 1234th registered data is read from the CMT, the registered data It is found that the receipt number in the data matches 1234 of the receipt number group in the work area, and the valid mark in this registered data is rewritten to an invalid mark, and this data to be canceled is stored in the CMT in the internal memory.
While in the read data store area, the quantity and amount of each product in the cancellation registration data are subtracted from each corresponding CNT and TTL in the product-specific accumulation area. In this way, all the normal registration data on the CMT is read and the cancellation registration is completed.

The above operation will be explained with reference to the flowchart shown in FIG. If any key input is detected in Judgment 1, it is judged as VOID key-in in Judgment 2, and if NO, it is judged as ST key-in, CASH key-in, number key-in to the left, and all are NO.
If so, it is another operation. When judgment 2 is YES, 1 is written in the registration cancellation flag area of internal memory RAM.
is set and returns to judgment 1. VOID for cancellation action
Since the numeric key is pressed after the key, then judgment 2 becomes NO, judgment 3 and 4 are both NO, judgment 5, the judgment of numeric key-in is YES, and the number of the receipt to be canceled is entered in the number area of RAM. be done. The next operation after setting the number is ST key-in, so judgment 1 is YES, judgment 2 is NO, judgment 3 is YES, and in judgment 6 it is judged whether the registration cancellation flag is 1 or not.If NO, this means that the VOID key is not pressed and the ST key is pressed immediately. Since this is an error, it is handled as an error, and if YES, the value in the numeric area is moved to the work area. At this time, since the operations are performed in the order of digit, ST, digit, ST, the receipt number digits are input into the work area in the order in which they are input. Judgment 1 because the last operation is CASH key-in
YES, Judgment 2, 3 is NO and Judgment 4 is YES,
Here too, if the registration cancellation flag is 0, an error will be processed,
Next, in judgment 7, it is checked whether or not a numerical value has been input into the work area of the RAM. If NO, an error process is executed, and if YES, rewinding of the CMT is started.
At the end of rewinding, reading of the CMT is started, one receipt at a time is read out, and in judgment 8 it is judged whether the receipt number in the read data matches the number in the receipt number set in the work area of the RAM, If there is no match (NO), it is determined in decision 9 whether or not CMT has ended, and if NO, the readout is further advanced. In this way, when decision 8 becomes YES, data that should be canceled from the CMT is found, so the product-specific accumulation area on the RAM is corrected 10 and an invalid mark is recorded at the beginning of the corresponding receipt number on the CMT.

FIG. 6 shows details of the operation in the product-specific accumulation area correction block 10 in FIG. Data read from the CMT is input to the read data store area of the RAM, and is rewritten as the read progresses. If the decision is YES, data indicating the first product code among the data input to the CMT data store area is set in the WADDR area of the RAM. Next, the RAM indicated by the above data of WADDR
The sales amount and quantity of the product on the receipt are subtracted and corrected from the data in the product-specific accumulation area of the above address, and the fact that the product has been canceled is printed on the record paper, and the WADDR data is updated by product on the RAM. The memory size for one product is added to the accumulation area (block 11), and in judgment 12 it is judged whether the correction has been completed for the product in the CMT read data.If NO, judgment 1 is made.
In step 3, it is determined whether the data of the product in the product accumulation area on the RAM specified by WADDR (the area of the product next to the previously corrected product) is in the CMT read data, and if NO, the operation returns to block 11.
If YES, the process returns to the top and performs the above-mentioned correction operation. When determination 12 is YES, an end line is printed on the recording paper.

Although this embodiment shows the case where a cassette tape is used, the same concept can be applied to the case where a floppy disk is used.

(Effect of the Invention) The present invention is configured as described above, and it is only necessary to note down the number of the receipt that requires cancellation registration, and then input only the receipt number after the end of the normal registration for the day. , it is not necessary to input all sales data for each receipt as in the past, which has the advantage of greatly reducing operator labor.In addition, the amount of data recorded in external memory is smaller than before, and registered data is This has the advantage of simplifying the programming of higher-level machines that perform aggregation processing using groups.
