DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention relates to a product sales data processing device such as an electronic cash register used in a store.

[Prior Art] Generally, a keyboard installed in an electronic cash register or a POS terminal of a POS (point of sale) system stores various numerical data such as the sales amount of sold products, the number of items sold, or the amount deposited by customers. In addition to the number keys from 0 to 9 for entering numbers, multiple department keys for entering department codes that categorize sales items, a subtotal key for calculating subtotal amounts, and registration cotton for cash payments. Various function keys are provided, such as a deposit/account key for commanding the number of entries, and a clear key for correcting entered numerical data and clearing error conditions.

Additionally, some machines are equipped with a ten-thousand-bill key for inputting the deposited amount in ten thousand when the customer pays the total amount using ten-thousand yen bills. With this system, for example, if a customer makes a purchase of 18,000 yen and pays with two 10,000 yen bills, the cashier can enter the number "2" using the number keys and then enter the 10,000-yen key to receive the deposit amount. 20,000 yen has been entered, change is calculated according to the key input of the deposit/cash total key, and a receipt is issued on which the total amount, deposit amount, and change amount are printed. Therefore, the cashier does not need to enter "0" four times when depositing 20,000 yen, improving operability and reducing input errors. In addition, a counter is usually provided for accumulating the numerical value input in ten thousand units using the ten thousand note key, and the number of ten thousand yen bills in the drawer can be managed by this counter.

[Problem to be Solved by the Invention] As described above, some of the conventional product sales data processing devices of this type are provided with a function key for inputting a specific unit of money (in this case, units of 10,000 yen). There is. However, the monetary unit is set in advance by the manufacturer and cannot be set freely by the user.

SUMMARY OF THE INVENTION Therefore, the present invention provides a product sales data processing device that is equipped with keys that allow the user to freely set monetary units, and that allows efficient key operations to be easily performed, for example, in inputting deposit amounts.

[Means for Solving the Problems] The present invention provides a product sales data processing device that registers sales data of each sales product inputted by operating various keys on a keyboard in a memory. A unit key is provided, a monetary unit table for storing monetary unit data corresponding to the monetary unit key is provided, monetary unit setting means is provided for arbitrarily setting monetary unit data stored in this table, and further comprising: , a monetary unit data reading means for reading the corresponding monetary unit data from the monetary unit tape 5 in response to input of the monetary unit key.

[Function] With a product sales data processing device that takes such measures, by operating a monetary unit key provided on the keyboard, monetary unit data set corresponding to that key can be read out. It is processed.

The monetary unit data corresponding to the monetary unit key can be set arbitrarily. Therefore, it is easy to obtain a monetary unit input key that corresponds to the usage conditions of the user.

[Example] Hereinafter, an example in which the present invention is applied to an electronic cash register will be described with reference to the drawings.

FIG. 1 is a block diagram showing the configuration of an electronic cash register. The CPU as the main body of the control unit has a built-in arithmetic circuit, a memory control circuit, etc., executes various arithmetic processing based on input data, and also has a ROM 3 that stores fixed data such as programs via a pass line 2. It controls the RAM 4 that stores variable data such as input data and arithmetic processing data. In addition, a clock circuit 5 that measures the date and time, an I10 boat 7 that inputs a selection signal from a mode switch 6 for selecting various business modes such as "registration", "payment", "setting", etc., and inputting sales data of each sales product. a keyboard circuit 9 for inputting key signals from the keyboard 8 for the purpose of displaying the information, a display control circuit 11 for driving and controlling the display 10 for displaying the total sales amount of the sold products, etc.;
The pass line 2 includes an I10 port 16 that outputs a drive signal to the printer drive circuit 13 of the printer 12 for printing sales data on receipts and journals, and the drawer opening device 15 of the drawer 14 for storing cash, etc.
It is connected to the CPUI via.

As shown in FIG. 2, the keyboard 8 has number keys 2 from 0 to 9 for entering various numerical data such as the sales amount and number of items sold or the deposit amount from customers.
1. In addition to multiple department keys 22 for inputting department codes for classifying sales products, a subtotal key 23 for calculating a subtotal amount, and a deposit/cash total key 24 for instructing detailed registration by cash payment, Various function keys such as a clear key 25 and a # key 26 are provided, which are used to correct entered numeric data and release error states.

In addition, there is a 10,000-yen key 27 for inputting units of 10,000 yen, and a number for inputting units of amount that can be set arbitrarily.
4 monetary unit keys 28-1.28 with numbers 1 to 4 set
-2.28-3.28-4 are arranged.

The RAM 4 includes a keyboard 8 as shown in FIG.
The key function code (SFKC: 5elective r) assigned to each key corresponds to the key number of that key.
Sales registration that cumulatively registers the number of sales items and sales amount of each sales product entered by key operations such as the key function table 31 storing the numeric key code 21 and the department key 22 of the keyboard 8, for example, by department code. A file 32, a number buffer 33, a totalizer 34 that calculates the total price of products sold to -1 customers, a deposit amount memory 35 that stores the deposited amount from customers, and input by key operations on the ten thousand ticket key 27. In addition to a 10,000-ticket counter 36 for accumulating numerical values in 10,000 units, an amount unit table 37 is provided. This amount unit table 37
, each monetary unit key 28-1 to 28- for set points 1 to 4 is pressed.
Corresponding to the key function code (SFKC) of 4 and its setting° black data, area A is used to store monetary unit data of the corresponding key, and for accumulating the numerical value of the corresponding monetary unit input by the key operation of the corresponding key. A counter area B is formed. The monetary unit data area A consists of an 8-bit area as shown in Figure 4, and the lower 4 bits indicate the unit (10,000, 1,000, 100, 10), and the upper 4 bits indicate the amount in that unit. There is. For example, if the monetary unit is 5,000 yen, the monetary unit data is [010101001.

The setting of monetary unit data for the monetary unit area A is performed by the CPU according to the flowchart shown in FIG. 5 with the mode switch 6 selecting the "setting" task.

That is, when a setting code is entered using the numeric key 21 and the subtotal key 23 is input in the "setting" mode, the CPU checks the type of the entered setting code as ST (step) 1. Then, when it is confirmed that it is the setting code for the monetary unit data, the setting code fish is entered in the monetary unit keys 28-1 to 28-4 using the number key 21 as ST2, and the # key 26 is input. wait. Then, when the numeric key 21 and the # key 26° are input, in ST3 it is confirmed that the numeric data specifies the set points of the monetary unit keys 28-1 to 28-4, and then in ST4 the monetary amount is The contents of the amount unit area and counter area corresponding to the corresponding set point data in the unit table 37 are cleared. Next, in ST5, monetary unit data is entered using the numeric key 21 and the subtotal key 23 is input. Then, when the number key 21 and the subtotal key 23 are input,
After confirming in ST6 that the numeric data is monetary unit data with the upper 4 bits indicating the amount in the 10's digit and the unit in the lower 4 bits in the 1's digit, in ST7 the numeric data is converted into an 8-bit monetary unit. Convert to data and store in cleared monetary unit data. Thereafter, the amount unit key 2 is not inputted in ST2 without inputting the deposit/cash key 24 in ST8.
When the set points 8-1 to 28-4 are input, the above-described process is repeated. When the deposit/cash key 8 is input in ST8,
This process ends.

In this way, each monetary unit key 28 is added to the monetary unit table 37.
By setting monetary unit data corresponding to the key function codes and setting points of -1 to 28-4, each monetary unit key 28-1 to 28-4 is set in the monetary unit set in the "registration" mode. Functions as an input key. Next, C
The processing in the "registration" mode of the PUI will be explained according to the flowchart shown in FIG.

First, for example, the number key 21 is used as the sales data of the sales product.
When the sales amount of the sold product is entered and the department code to which the product belongs is entered using the department key 22, the sales amount and number of sales items (-1 ) are cumulatively registered. Further, the sales amount is added to the totalizer 34. Furthermore, the department code and sales amount are displayed on the display 10 and printed out on the receipt and journal by the printer 12. Next, when the subtotal key 23 is input, the amount in the totalizer 34 is displayed on the display 10 as a subtotal amount, and is printed out on the receipt and journal.

After inputting the subtotal key 23, when the million ticket key 27 is inputted,
It is determined from the contents of the number buffer 33 whether or not a number has been entered using the number key 21 immediately before, and if it has not been done, r10,000 J yen is added to the deposit amount memory 35, and the ten thousand ticket counter 36 is set to " +1” only. After that, the subtotal key 23 returns to the input state and waits for the next key input. On the other hand, if the number has been placed, the system calculates the number data x 100OOJ yen, adds it to the deposited amount memory 35, and updates the ten thousand ticket counter 36 by the amount of the number data. The key 23 returns to the input state and waits for the next key input.

After inputting the subtotal key 23, press any one monetary unit key 2
When 8-1 to 28-4 are input, press number key 21 immediately before
The number buffer 33
Judging from the content. If not, the corresponding amount unit data is read from the amount unit table 37, the unit amount is added to the deposited amount memory 35, and the corresponding counter is updated by "+1". After that, the subtotal key 23 returns to the input state and waits for the next key input. On the other hand, if a deposit has been made, the corresponding monetary unit data is read out from the monetary unit table 37, and the "deposited value data x unit amount" yen is calculated and added to the deposited amount memory 35. Update the corresponding counter by the amount of data. After that, the subtotal key 23 returns to the input state and waits for the next key input.

When the deposit/cash total key 24 is input after the subtotal key 23 is input, it is determined from the contents of the number buffer 33 whether or not a number has been entered using the number entry key 21 immediately before. and,
If it has been done, the deposited amount will be stored in the deposit amount memory 3.
5 and compares the total amount in totalizer 34 with the deposited amount in deposited amount memory 35. On the other hand, if the number is not set, it is checked whether the contents of the deposit amount memory 35 are zero or not, and if it is zero, the customer has paid an amount equal to the total amount, so the amount in the totalizer 34 is stored in the deposit amount memory. 35, the total amount in the totalizer 34 and the deposited amount in the deposited amount memory 35 are compared. If it is not zero, press 10,000 tickets key 27
Alternatively, since the deposited amount has been input using the amount unit keys 28-1 to 28-4, the total amount in the totalizer 34 and the deposited amount in the deposited amount memory 35 are immediately compared.

When the total amount is compared with the deposited amount, if the total amount is larger than the deposited amount, the customer's payment is insufficient, so an error is displayed and the deposited amount memory 35 is cleared (error processing).

Thereafter, when the clear key 25 is input and the error state is canceled, the system waits for the similar amount to be manually input again.

If the deposit amount is greater than the total amount, the process will proceed to normal cash closing processing. That is, change is calculated by subtracting the total amount from the deposit amount, the change amount is displayed on the display 10, and the total amount, the deposit amount, and the change amount are printed out on a receipt and a journal, and only a receipt is issued.

Also, the drawer 14 is opened. After that, totalizer 34
Then, the contents of the deposited amount memory 35 are cleared and the sales registration process for one customer is completed.

In a store that employs the electronic cash register of this embodiment configured as described above, the user selects the "setting" mode with the mode switch 6, inputs the amount unit setting code with the number key 21, Next, subtotal key 23
Enter. Here, set NQI monetary unit key 28-
1 to set an amount of 5,000 yen, the user first enters the setting N111 using the numeric key 21, and then presses the # key 2.
Enter 6. Next, data showing the amount unit of 5,000 yen [5
4] and then input the subtotal key 23. By performing the above key operations, the 8-bit monetary unit data [01010100
(-54)] is stored, and the amount unit key 28-1 functions as a key for inputting the amount unit of 5,000 yen. Similarly, for example, the monetary unit data [000101
00(14)] is stored, the amount unit key 2
8-2 functions as a key for inputting the monetary unit of 1,000 yen, and the monetary unit data [01010010 (-52
)], the monetary unit key 2B-3 functions as a key for inputting the monetary unit of 500 yen, and the monetary unit data [[ 00010010(-12)] is stored, so that the amount unit key 28-4 functions as a key for inputting the amount unit of 100 yen.

In this way, with the electronic cash register of this embodiment, each amount unit key 28-1 can be controlled by a simple key operation.
~28-4 monetary units can be freely set. Further, it is also easy to change the monetary unit corresponding to each of the keys 28-1 to 28-4. Therefore, by setting the necessary monetary unit to each monetary unit key 38-1 to 28-4 according to the usage conditions of the user, it is possible to use the device with excellent operability and practicality, and to improve work efficiency.

For example, if a customer pays 15,000 yen in a registration process, conventionally, the number r15000J is entered using the number key 21, or r50000J is entered using the number key 21 after operating the ten thousand ticket key 27.
However, in this embodiment, the cashier can use the 10,000-ticket key 27 and the amount unit 5.
The deposit amount r15000J can be input simply by operating the amount unit key 28-1 to which 1,000 yen is set. In this way, the number of operating keys can be reduced, especially in the deposit amount input operation, improving work efficiency and reducing input errors.

Also, for example, although the monetary unit key 28-1 was initially selected as a key for inputting the monetary unit of 5,000 yen, the monetary unit key 28
If -4 is more convenient, the key position can be easily changed by resetting the monetary unit data corresponding to monetary unit keys 28-1 and 28-4 through monetary unit data setting work. Therefore, work efficiency can be further improved in response to the usage conditions of the user.

In addition, since the numerical value of the unit amount entered manually for each amount unit key 28-1 to 28-4 is accumulated by the counter, management similar to the management of 10,000 yen bills using the 10,000-yen bill counter 26 can be performed on other bills. This can also be done for denominations.

In addition, although the case where four monetary unit keys were provided was shown in the said Example, the number of keys is not limited and may be 1 to 3 or 5 or more. however,
It is necessary to form a monetary unit table corresponding to the number of monetary unit keys. Further, in the above embodiment, the amount unit key 28
-1 to 28-4 are used in the deposit amount input operation, but they can also be used in other applications depending on the program design. Furthermore, although the embodiment described above shows the case where the present invention is applied to an electronic cash register,
Needless to say, it can also be applied to POS terminals in POS systems. It goes without saying that various other modifications can be made without departing from the spirit of the invention.

[Effects of the Invention] As detailed above, according to the present invention, it is possible to sell a product that is equipped with a key that allows the user to freely set the unit of amount, and that allows efficient key operations to be easily realized, for example, in inputting the deposit amount. Data processing equipment can be provided.
