Abstract

PURPOSE:To decrease the mistakes concerning the deposits and to improve the operability of a commodity sales data processor by performing forcibly the input of a unit amount key in case the total amount is larger than the unit amount of the unit amount key. CONSTITUTION:When a cashier inputs a subtotal key 23 after registering all commodities purchased by one customer, it is decided whether the total amount of the commodities purchased by the customer, i.e., the amount calculated by a totalizer 33 exceeds Yen10,000 or not. If so, a forcible flag F2 is set at 1 and the input of a Yen10,000 paper moneys key 25 is forcibly performed. Under such conditions, the cashier inputs the amount of the Yen10,000 unit out of the deposit of the customer with use of the key 25 and also inputs the deposit less than the Yen1,000 unit with use of a register key 21 respectively. Then a deposit/ present total key 24 is operated so that the change is calculated by subtracting the total amount from the deposit. Then a receipt is issued. In this case, the Yen10,000 unit of the deposit is inputted by means of the key 25 in case the deposit of the customer exceeds Yen10,000. Therefore no deposit is inputted with the 5-digit registration by means of the key 21. Thus the input mistakes of the deposits can be decreased.

Description

[Detailed Description of the Invention] [Industrial Application Field] The present invention is applicable to product sales data processing devices such as electronic cash registers used in stores and PO5 (point of sale) systems employed in supermarkets. Regarding.

[Prior Art] In general, the keyboard of a PO8 terminal in an electronic cash register or POS system has number keys for inputting numerical data such as the sales amount of sold products and the amount deposited by customers. Department key for entering the department to which the product belongs, subtotal key for calculating the subtotal amount - Deposit/cash key for commanding the closing of registration for one customer and executing change calculation to subtract the total amount from the deposited amount There are various function keys such as. Additionally, some machines are equipped with a 10,000-ticket key for inputting the amount in 10,000 units when the deposit amount is 10,000 yen or more.

However, in conventional devices of this type, inputting the 10,000-ticket key was optional regardless of the number of digits of the deposited amount.

[Problems to be Solved by the Invention] As mentioned above, in the past, inputting the 10,000 ticket key was optional. Depending on the cashier, a 5-digit number may be entered using the number keys, such as rlooooJ, and in this case, input errors are likely to occur due to the large number of operating keys.

Therefore, the present invention provides a product sales data processing device that makes it possible to force input of the unit amount key when the total amount is less than the unit amount of the unit amount key, thereby reducing input errors in the deposit amount and improving operability. This is what we are trying to provide.

[Means for Solving the Problems] The present invention registers sales data of each sales product in a memory, adds the sales amount of the product using a totalizer,
In a product sales data processing device that calculates change and issues a receipt when there is a registration closing operation after inputting the subtotal key, the unit amount key is used to input the unit amount, and the amount in the totalizer is changed according to the input of the subtotal key. A total amount determination means for determining whether the total amount is greater than or equal to the unit amount, and when the determination means determines that the total amount is greater than or equal to the unit amount, the deposit amount is determined using the unit amount key in accordance with the registration closing operation. This system includes unit amount key input determining means for determining whether or not there is an input, and closing operation invalidating means for invalidating when the determining means determines that no deposit amount is input using the unit amount key.

[Operation] If the product sales data processing device takes such a measure, when the subtotal amount calculated by inputting the subtotal key is greater than or equal to the unit amount input using the unit amount key, the input of the unit amount key is forced. becomes. In this state, when the deposit amount is input and the registration closing operation is performed, it is determined whether the deposit amount was input using the unit amount key.

If the amount was entered using the unit amount key, change is calculated and a receipt is issued, and the sales registration for - customers is completed, but if the amount was entered without using the unit amount key, the closing operation is performed. is invalidated, and the user waits for the similar amount to be entered again and the registration closing operation to be performed.

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

FIG. 1 is a block diagram showing the configuration of an electronic cash register. A CPU (Central Processing Unit) 1, which serves as the main body of the control unit, has built-in arithmetic circuits, memory control circuits, etc., and performs various calculations based on input data. A ROM 3 that performs processing and stores fixed data such as programs for executing various tasks via the pass line 2, and a RAM 4 that has a memory for registering sales data of each sales product.
and control. Also, there is a clock circuit 5 that measures the time, an I10 boat 7 that inputs signals from the mode switch 6, a keyboard input circuit 9 that inputs and processes key signals from the keyboard 8, and a display section 10 that displays amount data and the like by electric light. a display control circuit 11 that drives and controls the display control circuit 11, a printer drive circuit 13 of the printer 12 that prints on receipts and journals, and an I10 port 16 that outputs drive signals to the drawer opening device 15 of the drawer 14 for storing cash and the like.
etc. are connected to the CPUI via the path line 2.

The mode switch 6 controls power on/off, selects various business modes such as "registration", "accounting", and "setting", and instructs the CPU to execute them, and is operated using a key. be done.

As shown in FIG. 2, the keyboard 8 includes number keys 21 for entering numerical data such as the sales amount of the sales product and the deposit amount from one customer, and a number key 21 for entering the department to which the sales product belongs. In addition to various function keys such as the department key 22, the subtotal key 23 for calculating the subtotal amount, and the deposit/cash total key 24 for instructing closing of sales registration for - customers and executing change calculation, as well as 10,000 yen units. A million ticket key 25 is provided for inputting the amount of money.

As shown in FIG. 3, the RAM 4 includes a sales registration file 31 for cumulatively registering sales data such as the sales amount and number of items sold for each product by department, transaction, etc.;
A number buffer 32 for temporarily storing the numerical data entered by 1, a totalizer 33 for adding up the sales amount of products sold to one customer, and a deposit amount for storing the deposit amount from the customer entered by key input. A memory 34, a flag memory 35 in which flags such as a million-ticket flag Fl and a forced flag F2 are set.
etc. are formed.

Therefore, the CPUI is set to "
The program is configured to execute the process shown in the flowchart of FIG. 4 when a sales product is registered in a department while the "registration" mode is selected. That is, ST(
When the sales amount of the sold product is entered in Step 1 and the department to which the product belongs is entered using the department key 22, the sales amount and number of sales items entered in the sales registration file 31 are accumulated for each corresponding department. register. Further, the entered department and sales amount are displayed on the display section 10 and printed out on the receipt and journal by the printer 12. Furthermore, the sales amount is added to the totalizer 3. After that, it waits for the next product to be registered, and if it is registered, the same process is repeated.

Then, when the subtotal key 23 is input in ST2, the amount in the totalizer 33, so-called subtotal amount, is read out and displayed on the display section 10, and is printed out on the receipt and journal. Next, in ST3, it is determined whether the subtotal amount read out is 10,000 yen or more, and if it is 10,000 yen or more, the forced flag F2 in the flag memory 35 is set to "1°" and
Proceed to T4 (total amount judgment means). If the amount is less than 10,000 yen, do nothing and proceed to ST4. In ST4, it waits for key data to be input from the keyboard 8. When the 10,000-ticket key 25 is input, the 10,000-ticket flag F1 in the flag memory 35 is set to 1'', and then it is determined whether or not a number has been entered using the numeric key 21 immediately before. If counting has not been done, store rl 0000J in the deposit amount memory 34 and return to ST4; if counting has been done, store rl 0000J in the deposit amount memory 34 and
Return to T4.

Further, if the deposit/cash key 24 is input in ST4, the compulsion flag F2 is checked in ST5.

Then, if the forced flag F2 is reset to "0", normal closing processing is performed and the process ends. Here, the normal closing process is to add the set amount in the number buffer 32 to the deposited amount memory 34, and subtract the total amount in the container 33 from the deposited amount in the deposited amount memory 34. Performs a change operation to calculate change, displays the change on the display unit 10, prints the total amount, deposit amount, and change amount on a receipt and journal, issues a receipt, and clears totalizer 33 and deposit amount memory 34. This is the process of

On the other hand, if the compulsion flag F2 is set to "1" in ST5, the ten-thousand-ticket flag F1 is checked in ST6 (unit amount key input determination means). And the million ticket flag is “1”
If it is set to ``, the deposited amount has been input using the 10,000-ticket key 25, so normal closing processing is performed, the 10,000-ticket flag F1 and the forced flag F2 are reset to ``0'', and the process ends.

On the other hand, in ST6, the 10,000-ticket flag F1 is “O”.

If the total amount is 10,000 yen or more and entry of the deposit amount using the million ticket key 25 is forced, the deposit amount will not be entered using the million ticket key 25, so it will be treated as an error. After clearing the deposit amount memory 34, the process returns to ST4 and waits for the similar amount to be input again (closing operation invalidation means).

In the electronic cash register of this embodiment configured in this way, when the cashier registers all the products sold to one customer and then inputs the subtotal key 23, the total amount of all the products sold to that customer, that is, the total It is determined whether the amount calculated by the device 33 is 10,000 yen or more, and if it is 10,000 yen or more, the forced flag F2 is set to 1'' because the customer will pay 10,000 yen or more. In this state, the cashier inputs the amount of the customer's deposit in 10,000 using the 10,000 ticket key 25, and inputs the deposit amount in 1,000 or less using the number key. 21 and operate the deposit/cash key 24, a change operation is performed to subtract the total amount from the deposited amount, and a receipt is issued. If the cashier inputs the deposit using the ten thousand ticket key 25, an error will occur. Therefore, the cashier will have to input the deposit amount in ten thousand units using the ten thousand ticket key 25.

As described above, according to this embodiment, when the total amount is 10,000 yen or more, that is, when the deposited amount from the customer is 10,000 yen or more, the deposited amount is set in 10,000 units without fail by pressing the 10,000 ticket key 25. Therefore, there is no need to use the number keys 21 to input five or more digits to enter the deposit amount, and errors in inputting the deposit amount can be reduced. As a result, operability can be improved and accounting operations can be speeded up.

In the above embodiment, the ten thousand ticket key 25 for inputting 10,000 yen was used as an example of the unit amount key, but the present invention is also applicable to other unit amount keys for inputting other unit amounts, such as 100,000 yen. It goes without saying that the present invention can also be applied to a POS system in which a plurality of PO8 terminals with different monetary unit keys are connected. 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, when the total amount is greater than or equal to the unit amount of the unit amount key, input of the unit amount key is forced, thereby reducing input errors in the deposit amount, It is possible to provide a product sales data processing device that can improve operability.
