Description

DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention relates to an electronic cash register suitable for use in various shops.

[Prior Art] In this type of conventional electronic cash register,
Product codes as product sales data from input devices such as keyboards and barcode scanners.

When the sales amount, number of items sold, etc. are entered, at least the product code or product name and sales amount are printed on the receipt and journal and displayed on the display. ), the customer can confirm that the product sales data has been registered in the storage section of the electronic cash register. In addition, when you operate the closing key after registering all product sales data, the sales amount will be displayed on the display, so the customer will pay that amount to the store manager, and the cashier will calculate the change and calculate the number of items sold, the sales amount, and the sales amount. .

A receipt with the amount of change printed will be issued. Thus,
Commodity trading operations for one customer are completed.

[Problems to be Solved by the Invention] However, conventional electronic cash registers have the following problems. That is, the data displayed on the display unit during product registration is only the product code or name of the product being sold and the sales amount, and the sales amount is not displayed until the registration is completed. Therefore, if a customer requests to know the amount of sales to date during registration, the cashier must temporarily stop the registration process by operating the subtotal key, etc., resulting in a decrease in operability. Ta.

Therefore, the present invention provides an electronic cash register that is capable of displaying the current total score and total amount each time product sales data is registered, thereby improving service to customers and improving operability. The purpose is to provide

[Means for solving the problems] The present invention has the following features:1. The product sales data inputted from the input section a1 is registered in the storage section a2, and the number of items sold and the sales amount for one customer are accumulated on an electronic cash register that displays at least the sales amount of the product sales data on the display section a3. A score/subtotal area B having a score area and a subtotal amount area is provided, and a display C is provided to display the contents of the score area and subtotal amount area of this score/subtotal area B. Accordingly, the number of sales points and the sales amount are added to the points area and the subtotal amount area of the points/subtotal area B, respectively, using the adding means, and the contents of the added points/score area and the subtotal amount area of the subtotal area B are displayed. The control means E causes the display C to display the information.

[Function] With an electronic cash register that takes such measures, when product sales data is input from the input section, the sales amount and number of sales items are added to the points area and amount area of the points/subtotal area. Since the added data is displayed on the display, the customer can grasp the current number of purchased items and purchase amount each time a product is registered for sale.

[Example] Hereinafter, an example of the present invention will be described with reference to the drawings.

FIG. 2 is a perspective view showing the external configuration of the electronic cash register of this embodiment. In the figure, 1 is a register housing, and a keyboard 2 is provided on the front surface of this housing 1. Further, above the housing 1, there is a first display section 3a for displaying the sales amount 1 total amount, etc., and a second display section 3b for displaying the total score and total amount at the time of product sales data registration. A two-stage display 3 consisting of
1 to 1 and a printer section 4 having a built-in printer for printing product sales data on the journal are arranged in parallel.

Incidentally, the printer section 4 is formed with an issuing port 5 to the cash register 1. Further, a drawer 6 for storing cash and the like is installed on the bottom surface of the housing 1, and a card reader 7 for reading information recorded on credit cards, ID cards, etc. is attached to the side surface.

FIG. 3 is a diagram showing the key layout of the keyboard 2. As shown in FIG. As shown in the figure, the product code and
a number key 11 for entering sales amount, number of items sold, etc.;
department key 12 for setting the department code of the sales product;
In addition to various function keys such as a subtotal key 13, a deposit/cash total key 14, a PLU key 15 for setting a PLU code, and a multiplication key 16, a control key 17 is arranged.

The control key 17 is a control switch for controlling the power supply on/off and instructing the central processing unit to execute various business modes such as "registration", "accounting", and "setting". Furthermore, "registration" means storing the sales amount, number of items sold, etc. of the sold product in the storage unit according to the product code, calculating the total amount, etc., displaying the result on the display unit, and registering at the register 1. - This is the job of printing on a journal. Furthermore, "settlement" is a task of printing out the sales total etc. stored in the storage unit at the end of the day's work. "Setting" is a task in which data necessary for the "registration" task is preset in the storage unit prior to the start of the "registration" task.

FIG. 4 is a block diagram showing the internal configuration of the electronic cash register. In the figure, a CPU 21 has a built-in arithmetic circuit, a memory control circuit, etc., and performs various xi processing based on input information from the keyboard 2, as well as pass line 22. A ROM that stores fixed data such as execution programs for the various tasks mentioned above via the control signal Pi123.
24 and a RAM 25 which stores the sales amount of the sold products, the total amount of the number of sales items 9, etc., are operated. Also, a keyboard input circuit 26 for inputting key signals from the keyboard 2;
Printer 27 that prints on receipts and journals
Drawer opening to open the printer drive circuit 28 that drives the drawer 6! A drawer control circuit 30 that controls the i18 and 29, a display control circuit 31 that controls the display of the upper display section 3a and the lower display section 3b, and a card reader control circuit 32 that controls the card reader 7 are connected to the pass line 22. It is connected to the CPU 21 via a control signal a23.

Further, as shown in FIG. 5, the RAM 25 includes a product registration file 41 that stores sales amount, number of items sold, number of items sold, amount of sales, etc. for each PLU code;
A PLU file 42 in which a name and a single image are set according to the code, and a points/subtotal area that includes a points area and a subtotal amount area to which the number of sales items and sales amount of sold products are added according to the registration of product sales data. 43 and number key 11
A number buffer 44 stores numerical data, an upper display buffer 45 stores display data displayed on the upper display section 3a, and a lower display buffer 46 stores display data displayed on the lower display section 3b. , a print buffer 47 for storing print data to be printed on receipts and journals.

The CPU 21 is programmed to operate in accordance with the procedures shown in FIGS. 6 and 7 when performing PLU registration. That is, PLL
When the I key 15 is operated, as shown in FIG.
4, and if it is stored, the stored number data is set in the PLU code, and this set PLU code is used to write the PLU file 4.
Search for 2. Then, in ST2, it is determined whether a PLU code corresponding to the set PLU code exists in the PLU file 42, and if it exists, the name and unit price corresponding to the code are read out in ST3. Next, S
If the sales number of the product is specified by operating the east line key 16 as T4, the unit price read in ST3 is multiplied by this sales number, and this multiplication result and sales number are displayed in the points/subtotal area 43. Add each to the subtotal amount area and the points area. Then, in ST5, the name information and riding result information read in ST3 are transferred to the upper display buffer 45, and these are displayed on the upper display section 3a. on the other hand,
If the number of sales items is not specified in ST3, ST
Add the unit price read in step 3 to the subtotal amount area of the points/subtotal area 43, and increase the points area by "+1". and,
The name information and unit price information read in ST3 are transferred to the upper display buffer 45 as the 8th block 6, and these are displayed on the upper display section 3a.

After that, as ST7, the contents of the score/subtotal area 43 are transferred to the lower display buffer 46, and these are transferred to the lower display section 3b.
to be displayed. Also, ST5 or ST6 as ST8
The same data as the data transferred to the upper display buffer 45 is transferred to the print buffer 47, and the printer 27 is driven to print on the L sheet and the journal. Then, after clearing the contents of the same number buffer 44, a transition is made to the next key standby state.

In this state, if a closing key such as the deposit/cash total key 14 is operated, as shown in FIG. If so, in ST12, change calculation is performed to subtract the total amount stored in the subtotal amount area of the points/subtotal area 43 from the number data, and the change calculation result information is transferred to the upper display buffer 45 and displayed in the upper row. Display section 3a
to be displayed. Also, the change calculation result information in STI 2 is transferred to the print buffer 47 and printed on the receipt and journal.

On the other hand, if the number data does not exist in ST11,
As ST13, the contents of the subtotal amount area in the points/subtotal area are transferred to the upper display buffer 45, and the contents, that is, the total amount, are displayed on the upper display section 3a, and also transferred to the print buffer 47 to be printed on the receipt and journal. .

Thereafter, at step 5T14, the drawer 6 is opened, a receipt is issued from the receipt issuing port 5, and after completely clearing the point ril/subtotal area 43, the system shifts to a state of waiting for input of product sales data for the next customer.

In the electronic cash register of this embodiment configured as described above, the cashier uses the number key 11 and the PLU.
Each time you input product sales data using key 15,
The name and sales amount of the product are displayed on the upper display section 3a of the display 3, and the number of items purchased and the purchase amount at that time are displayed on the lower display section 3b. Therefore, the customer can know the current subtotal amount without the cashier operating the subtotal key 13 during a product transaction. therefore,
This is very convenient when you don't have much money and there are limits to what you can buy. Furthermore, since the cashier does not have to operate the subtotal key 13 in response to a customer's request during the registration process, he or she only has to input the product sales data one by one, thereby improving operability. Therefore, since the registration work time is shortened, there is no risk of having customers at the checkout place even during busy times such as evenings and weekends.

Note that the present invention is not limited to the above embodiments.

For example, in the above embodiment, a case was explained in which PLU registration is performed for product sales data, but department registration may be performed by operating the department key 12, or by attaching a barcode scanner to an electronic cash register and using barcode registration. A similar effect can be obtained even with single item registration that reads a single item code such as a standardized JAN code. In addition, when registering a single item by reading the barcode affixed to the product using a barcode scanner, conventionally the display did not change if the same product was read repeatedly, so it is difficult to know if it was registered correctly. Neither the cashier nor the customer could figure it out. However, by applying the electronic cash register of this embodiment, when the same product is read continuously, the display on the lower display section 3b increases, so that it can be known that the product has been accurately registered. It goes without saying that various other modifications can be made without departing from the gist of the present invention.

[Effects of the Invention] As described in detail above, according to the present invention, a score/subtotal area having a score area and a subtotal amount area for cumulatively totaling the number of sales items and sales amount for one customer is provided, and this score/subtotal area is provided. A display device is provided to display the contents of the points area and the subtotal amount area of the subtotal area, and the number of sold items and the sales amount are added to the points area and the subtotal amount area of the points/subtotal area, respectively, using an adding means according to the registration of product sales data. Add this added score/score area 1 of the subtotal area
Iil! Since the contents of the subtotal area and the subtotal amount area are displayed on the display device by the display control means, the current total score and total amount can be displayed every time product sales data is registered, which improves customer service. It is possible to provide an electronic cash register that can improve operability as well as improve operability.
