Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a product sales data processing device such as an electronic cash register or a POS system in which a plurality of registers are centrally managed by a controller, and more particularly to a device capable of efficiently processing fractions of change. ..

[0002]

2. Description of the Related Art For example, in a mass-market store such as a supermarket, various products whose unit price is a fraction of 10 yen or 1 yen are sold, so that the total amount of money of the customer is 10 yen or 1 yen. It often becomes a fraction. Since customers do not have coins and it is troublesome to collect cash for the total amount, they will pay in large units rather than fractional units and receive change, but the change at that time is necessarily 10 Fractions in yen units or 1 yen units are generated. For this reason, if fractions are generated, it takes time to exchange small coins, which lowers work efficiency, and the store side has to prepare a large amount of coins as change cash.

Therefore, a commodity sales data processing device which solves such a problem is described in Japanese Patent Laid-Open No. 2-287695. This is because for a specific customer, the fractional amount of the change amount is cumulatively stored in a storage unit in the device or a storage unit of a customer card issued by the store at the request of the customer.
The amount of money excluding the fraction is output as change. Then, when the accumulated fractional amount reaches a predetermined amount, a service ticket based on the amount is issued.

[0004]

This solves the problem of exchanging coins. However, in such a conventional product sales data processing device, the shop side must newly prepare a service ticket instead of the change, and the preparation of the service ticket is a considerable burden on the shop. In addition, this service ticket tends to be a high-priced service ticket because it is issued when the fractional amount reaches a predetermined amount, so it is necessary to manage storage, the number of issued cards, etc. as with gift certificates and prepaid cards. There is a problem that the work is very troublesome. The present invention has been made in view of the above problems of the prior art, and an object of the present invention is to provide a product sales data processing device that can reduce the burden on the store side and can perform the accounting operation efficiently by eliminating the fraction of change. ..

[0005]

The product sales data processing apparatus of the present invention prints the registration data on an input section for inputting the data, a display section for displaying the registration data input from the input section, and a receipt. A printing unit, calculating total amount data of one customer based on registration data of one customer input from the input unit, and deposit amount data according to the deposit amount data input from the input unit. A customer who inputs customer information from the input unit in a product sales data processing device that calculates change amount data from data and total amount data and outputs change amount data to the display unit and the printing unit. Information input means, a reference value storage unit for storing reference value data when calculating fraction data corresponding to the fraction of change, the fraction data of the customer stored corresponding to customer information, Return data and fraction data are calculated based on the total amount data, the deposit amount data, and the reference value data, and the return data is output as change amount data to the printing unit and the display unit, and the fraction data is the customer information. Corresponding to the change fraction processing means to be stored in a predetermined storage means and the presence or absence of customer information input according to the deposit amount input from the input unit, if there is no customer information input, The change output processing control means for executing the change output processing and operating the change fraction processing means when the customer information is input is provided.

[0006]

[Operation] When customer information is input, return data and fraction data are calculated from the customer's fraction data, total amount data, deposit amount data, and reference value data, and the return data is printed as change amount data. And the fraction data is stored in a predetermined storage means in correspondence with the customer information. If the customer information is not input, the change amount data is calculated from the deposit amount data and the total amount data as before, and is output to the display unit and the printing unit. This eliminates the exchange of fractional amounts.

A PLU key 18 used when registering a product by entering a product code, a subtotal key 19 used when outputting the total registered amount of one customer, a customer key 20 used when entering a customer code, It is composed of a deposit / cash total key 21 which is a closing key. The ten key 16 and the customer key 20 are customer information input means.

FIG. 4 shows a customer management table 2 which is a reference value storage unit provided in the file controller 1.
It is a figure which shows 2. The customer management table 22 identifies the customer code area 221, which stores the customer code, the name area 222, which stores the customer name, the fractional amount area 223, which stores the change amount of the customer who is entrusted, and the number of yen that is less than or equal to the fraction. It is composed of a fraction data area 224 for storing fraction data for performing.

FIG. 5 is a block diagram of this main memory provided in the RAM 7. The RAM 7 is a fractional amount memory 23 (A) that stores the fractional amount of money of the customer received from the file controller 1, a fractional data memory 24 that also stores the fractional amount of data received from the file controller 1, and a total amount of the total amount of money of one customer. Memory 25, deposit amount memory 26 that stores the amount of money deposited from customers, change amount memory 27 (B) that stores the amount of change generated in this transaction, and which amount of fraction is less than or equal to the fraction data corresponding to fraction data. It comprises a fraction information table 28 for storing data, a subtotal flag memory 29 indicating that subtotal processing has been performed, a customer flag memory 30 indicating that customer registration has been performed, and the like. The fraction information table 28 is composed of a fraction data area 281 for storing fraction data and a fraction area 282 for storing a reference amount of money as a fraction. If 100 is stored in the fraction area 282, less than 100 yen is treated as a fraction. Further, the subtotal flag memory 29 is set to 1 when the subtotal key is pressed and the subtotal processing is performed.

FIG. 6 is a flow chart showing the processing of this embodiment. In this embodiment, the rounding of the change is performed only for the customer who has a special contract with the store, and whether the customer is a customer or not is determined by the customer when the registration is started. However, by inputting a customer code provided for each customer, the change processing of the change is executed. This flowchart is executed when any key is operated on the keyboard 8.

It is determined whether the key input in step 100 is the customer key 20, and if it is not the customer key 20, step 10
In step 7, it is determined whether it is the deposit / cash total key 21, and the deposit / cash total key 2
If not 1, other processing is executed in step 123. As other processing, there is subtotal processing for outputting the total registered amount of one customer on the display device 11 or the like.

If it is determined in step 100 that the key is the customer key 20, in step 101 it is inquired whether or not the customer code is stored in the customer management table 22 of the file controller 1, and in step 102 registration is performed based on the response. Determine if it is a possible customer. If the customer code is not stored in the customer management table 22, step 1
In 03, error processing is executed. In this case, you will be registered as a general customer.

If it is a response that can be registered, in step 104, of the fractional amount data and the fractional amount data included in the response, the fractional amount data is stored in the fractional amount memory (A) 2
3, the fraction data is stored in the fraction data memory 24 in step 105, 1 is set in the customer flag memory 30 indicating that the customer code has been input in step 106, and the process ends.

If it is determined in step 107 that the key is the deposit / cash total key 21, it is determined in step 108 whether 1 is set in the subtotal flag memory 29. If 1 is not set, the subtotal processing is performed. Since the deposit / cash total key 21 is operated without being removed, it is determined as an operation error and error processing is executed in step 109. If 1 is set in the subtotal flag memory 29, the numerical data entered before the deposit / cash total key 21 is operated is stored in the deposit amount memory 26 as the deposit amount from the customer in step 110. In step 111, the change amount is calculated from the data in the total amount memory 25 storing the registered total amount of the customer and the deposit amount memory 26 and stored in the change amount memory (B) 27. This is done by subtracting the data in the total amount memory 25 from the data in the deposit amount memory 26. In step 112, it is determined whether or not 1 is set in the customer flag memory 30, and if 1 is not set in the customer flag memory 30, it means that the customer is a general customer.
The drawer is opened at 0, 121 and 122, the content of the change amount memory (B) 27 is displayed on the display unit 11, and the receipt amount, change amount, etc. are printed on the receipt and issued.
Then, in step 119, the various memories are cleared and the process ends. Steps 110, 111, 121 and 122 are change output processing.

If "1" is set in the customer flag memory 30, the customer code has been entered, so the process proceeds to step 113 to execute the rounding processing of the change. Step 11
The change amount up to the previous time stored in the fractional amount memory (A) 23 in 3 is added to the change amount of this time stored in the change amount memory (B) 27, and is stored in the change amount memory (B) 27. To do. In step 114, the fraction of the change is calculated based on the fraction data stored in the fraction data memory 24, and the change amount to be returned to the customer is determined. This is because the fraction information table 28 is searched for fraction data that matches the fraction data stored in the fraction data memory 24, and the basic amount of the fraction corresponding to the fraction data is called from the fraction area 282. Change amount memory (B)
This is done by dividing the 27 data. The positive amount calculated in this way is stored in the change amount memory (B) 27 as change for returning, and the surplus part is stored in the work memory as a fractional amount. And step 115
Then, the calculated fractional amount is transmitted to the file controller 1, the change amount to be returned is displayed on the display unit 11 in step 117, the change amount, the fractional amount, etc. are printed on a receipt and a journal in step 118, and various memory is stored in step 119. Is cleared and the process ends. Note that steps 110 and 1
11, 113, 114, 115, 117, 118 are change fraction processing means, and step 112 is change output processing control means.

Next, the operation of this embodiment will be described. FIG. 7 is a diagram showing an example of printing a receipt issued in this embodiment. It is assumed that a customer who is registered as a customer purchases. It is assumed that the total amount of money purchased is 618 yen, and the fractional amount of money managed by the store is 55 yen. The customer code for this customer is 0
If it is 00001, the operator tells the customer that he is a customer and the customer code is 000001,
Customer key 2 after entering 000001 with numeric keypad 16
Operate 0. Since an inquiry is made to the file controller 1 and the customer code 00000001 is stored in the customer table 22, the file controller 1 returns 55 as the fractional amount and 3 as the fractional data. This makes registration possible, and the fractional amount memory (A) 23 is filled with 5
5 yen is stored, 3 is stored in the fraction data memory 24, and 1 is stored in the customer flag memory 30.

When the registration is completed and the subtotal key 19 is operated, the total amount 618 yen is displayed on the display unit 11. If the customer pays 1000 yen for this, the operator operates the deposit / cash total key 21 by entering "1000" on the ten-key pad 16. Then, the total amount of 618 yen is subtracted from the deposit amount of 1000 yen to calculate the change of 382 yen. Here, the customer flag memory 30 is checked, and since the flag is set, fraction processing is executed. The calculated change of 382 yen is added with 55 yen stored in the fractional amount memory (A) 23 transmitted from the file controller 1 to calculate the total change of 437 yen. Then, the fraction information table 28 is searched with the fraction data stored in the fraction data memory 24 to obtain the reference value. In this case, since the fraction data is 3, the reference value is 100, and the fraction less than 100 yen is the fraction. Therefore, 437 yen is 10
37 yen, which is the remainder when divided by 0, is used as new fraction data. The remaining 400 yen is displayed as change on the display 11 and is output to the R / J printer 13. Fraction data 3
7 yen is transmitted to the file controller 1 and is stored as new fraction data in the fraction amount area 223 of the customer code 000001. The printing example is 40 as shown in (a).
0 yen is printed as change, and as shown in (a), the fraction newly generated in this transaction is printed as the fraction this time.

As described above, the commodity sales data processing apparatus of the present invention can efficiently process the exchange of change and can change the reference value for calculating the fraction for each customer. , We can respond to customer's request. Further, since the fractional amount of money does not exceed the reference value (if the reference value is 100 yen, the fractional amount of money is only 99 yen at maximum), the stored amount of money does not become high. The present invention is not limited to the above embodiment. For example, although the system including the host and the terminal has been described in the above embodiment, a single electronic cash register may be used, or a customer management table may be provided in the file controller 1 to collectively manage the fractional data of the customer. However, a customer card having a storage medium such as a magnetic card may be provided with fractional data of the customer. In that case, the means for reading the card information becomes the customer information input means. Besides, various modifications can be made without departing from the scope of the present invention.

[0021]

As described in detail above, according to the present invention,
Since there is no issuance of service tickets and the like, there is not much burden on the store side, the exchange of fractional amounts of change for specific customers is eliminated, and the efficiency of accounting work is improved, which is an excellent effect.
