As described above, in the related art, since it is necessary to always have two display devices, there is a drawback that the cost is increased. By the way, the operator need only confirm the registered contents registered this time when looking at the display screen. On the other hand, if you want to correct the registered content, let the customer disclose the registration details data up to that point,
Trouble with the customer is less likely to be corrected while interacting with the customer. However, in the past, since the registration detail data for one transaction is displayed on the operator-dedicated CRT display device, the entire display screen becomes complicated, the readability is poor, and even if the registered contents registered this time are to be confirmed. It had the drawback of not being able to read it immediately. Further, when the registered content is corrected, the customer cannot see the registration detail data, which causes a problem in reliability. An object of the present invention is to enable one display device to be used for both an operator and a customer, and to display necessary and appropriate data for an operator and a customer in a registration process for registering sales data for one transaction. Is to

On this registration screen, a column D-1 in which "date", "person in charge", and "mode" are displayed, a column D-2 in which the product name, quantity, and price registered this time are displayed, and a subtotal is displayed. Column D-3 and a column D-4 in which deposits and change are displayed when tightening a cash key or the like. The detail screen is a display screen of a predetermined format as shown in FIG. 11 generated by the detailed fixed display data read from the ROM 12 when the detail display key FK is operated. ], "Mode" is displayed in the column D-11, the product name,
It has a column D-12 in which the unit price, the number of units sold, and the amount of sales are sequentially displayed for each product, and a column D-13 in which a subtotal is displayed. The RAM 17 includes a PLU totalizer 17-1, another totalizer 17-2 for each person in charge, a specification buffer 17-3, a subtotal register 17-4, a number counter 17-5, a work memory 17-6, and the like. Has become. PLU totalizer 1
7-1 stores a product code, a character (unit price), a sales amount, etc. for each product, and the sales amount, etc. of the product is updated every time the product is registered. Detail buffer 1
7-3 stores the registration contents (commodity name, unit price, sales quantity, sales amount) for one transaction one by one as registration detail data for each registration by product, and a cash key for terminating the registration of one transaction. The contents are cleared when the tightening key such as is operated. The contents of this specification buffer 17-3 are the CPU 1
It is read according to the value of the detailed BF pointer 11-1 in 1 and displayed and output on the detailed screen of the CRT display device 6. When any registered detailed data displayed and output on this detailed screen is designated by the cursor and the data is designated and corrected, the value of the cursor pointer 11-2 in the CPU 11 is set to the detailed BF pointer 11-1. . The subtotal register 17-4 is a register that stores the total amount of money that is updated each time product registration is performed, and the number counter 17-5 that is updated each time product registration is performed. It is a counter that counts the total number.

Next, the operation of this embodiment will be described. FIG. 3 is a flowchart showing the operation in the registration mode in which the mode switch is set to the "REG" position. First, after performing various initialization processes (step A1), the CPU 11
Enters an input waiting state (step A2). Here, when the product code is input from the fixed scanner 4 or the keyboard 5 or the subtotal key is operated (step A3),
Registration processing is performed (step A4).

FIG. 4 is a flow chart showing this registration processing, and FIGS. 7 to 10 show display examples of registration screens that sequentially change as the registration processing progresses. First, C
The PU 11 checks whether the subtotal key has been operated (step B1). Now, when the product code is input, if it is the first registration of one transaction, that is detected in step B2 and the process proceeds to step B4, and the PLU totalizer 17-1 is searched based on the input product code. Then, the unit price of the corresponding product is read and added to the sales amount, or the number of units sold is updated. Then, the product name and unit price are displayed and output on the registration screen (step B5), and the receipt /
The journal is printed out (step B6). next,
The contents of the subtotal register 17-4 and the number counter 17-5 are updated in accordance with this registration (step B7). Figure 7
(A) shows the registration screen when the first registration is performed,
The product name and unit price of the product registered this time are displayed. next,
Going to step A5 in FIG. 3, the detailed BF pointer 11-1
The registered content registered this time is stored as detailed data in the address position of the detailed buffer 17-3 designated by the above, and the value of the detailed BF pointer 11-1 is updated for one record (step A6).

Then, when the next product code is input,
In the registration process (step A4), since it is detected in step B2 that it is not the first registration, the process proceeds to step B3, and the contents of the subtotal register 17-4 and the number counter 17-5 are displayed and output on the registration screen. FIG. 7B shows a display example in this case. Then, as a result of executing steps B4 to B7 for the product, the registration screen is shown in FIG.
As shown in (A). Subtotal register 17 in this case
-4, the value of the number counter 17-5 becomes the registration update value up to the previous time. Then, the registered contents this time are stored in the detail buffer 17
-3 is written (step A5), and the description BF
The pointer 11-1 is updated (step A6). Hereinafter, the above-described operation is repeated every time the product code is similarly input. As a result, the registration screen sequentially changes as shown in FIGS. 8B, 9A, and 9B each time the product code is input.

When the subtotal key is operated, this is detected in step B1 of FIG. 4 and the process proceeds to step B8 to calculate the consumption tax rate based on the value of the subtotal register 17-4 and the consumption tax rate. Processing is performed. Then, the consumption tax and the subtotal amount in the subtotal register 17-4 are added to obtain the total billed amount (step B9). And FIG.
As shown in (A), in the item column of the product name, the subtotal amount in the subtotal register 17-4 is displayed together with the character string "commodity fee", and in the item column of the number and amount, "consumption tax" is displayed. The amount of money is displayed together with the character string "," and the total amount billed (subtotal + consumption tax) is displayed together with the value of the number counter 17-5 in the subtotal item column.

When a closing key such as a cash key is input to complete the registration of one transaction, the closing is detected in step A7 of FIG. 3 and the closing process is performed (step A8). In other words, when the deposit is entered, the change is calculated and the drawer is opened. Then, the deposit and change are displayed and output on the registration screen (FIG. 10).
(See (B)) and print out on receipt / journal. When such a closing process is completed, the detail buffer 17
-3, the subtotal register 17-4, and the number counter 17-5 are cleared (step A9), and the detail BF pointer 11-1 is cleared to return to the initial value (step A1).
0).

On the other hand, before the tightening key is operated,
When correcting the registered contents, the detail display key FK is operated. Then, the fact is detected in step A11, and the process proceeds to step A12 to perform the detail display processing. As a result, the display content of the CRT display device 6 is switched to the detailed screen, and when the cursor key is operated to specify the correction position on this detailed screen, the fact is detected in step A14 and the process proceeds to step A15 to move the cursor. When the control process is performed and the correction key BK is operated to correct the data at the designated position, that is detected in step A16 and the correction process is performed (step A1).
7). Here, FIG. 5 is a flowchart showing the detail display processing and the cursor control processing, and FIG. 6 is a flowchart showing the correction processing. First, in the detail display processing, the CPU 11 reads the fixed data for details from the ROM 12, causes the CRT display device 6 to display and output the fixed data, and switches to the detail screen (step C1). Next, description B
While clearing the F pointer 11-1 (step C
2) Initialize the detail screen, and set the date, person code, etc. in the detail screen (step C3). And statement B
Detail buffer 1 specified by F pointer 11-1
Data for one record (one registration) is read from the address position 7-3 (step C4), and it is checked whether or not there is data at the address position (step C5). If there is no data, the detail display processing ends at this point, but if there is data, the data is displayed and output for one line from the beginning of the detail screen (step C6). Then, the display pointer (not shown) of the detail screen is updated for one line (step C7), and as a result, it is checked whether or not one screen is finished (step C8). Here, the detail display process ends when the data for one screen is displayed, but
If the screen has not ended, the value of the detail BF pointer 11-1 is incremented (step C9), and the process returns to the process of reading one record of data from the detail buffer 17-3 according to this value (step C4).

Now, for example, as shown in FIG. 11, with the contents of the detail buffer 17-3 displayed and output on the detail screen, the cursor key D for designating the correction position is displayed.
When K is operated, the process proceeds to step C10, where the cursor pointer 11-2 is updated and it is checked whether the previous screen is designated (step C11).
The value of the specification BF pointer 11-1 is moved back by one screen (step C12), and the specification BF pointer 11-
The process returns to the process of reading the contents of the detail buffer 17-3 for one record according to the value of 1 (step C4). On the other hand, if it is not the previous screen, the cursor is displayed on the detailed screen according to the value of the cursor pointer 11-2 (step C13).

When the correction position is designated by displaying the cursor at any position in the detailed screen in this manner and the correction key BK is operated to correct the registered data at that position, the correction process shown in FIG. 6 is performed. Is done. First, the detailed BF pointer 11 according to the value of the cursor pointer 11-2.
The value of -1 is changed (step D1). Then, according to the value of the specification BF pointer 11-1, data for one record is read from the specification buffer 17-3 (step D2). Here, when the correction data corresponding to this data is input, the registered content is corrected based on the input data (step D3). Then, the corrected data is displayed and output on the detail screen (step D
4), print output (step D5).

Here, in the state where the detailed screen is switched, only the cursor key DK, the correction key BK, and the display return key GK are valid keys, and the detailed screen remains until the display return key GK is operated. . Display return key G
When K is operated, this is detected in step A18, the process proceeds to step A19, the display content of the CRT display device 6 is returned to the registration screen, and then the input waiting state of step A1 is entered. When any other function key is operated, the process corresponding to that key (step A1)
Perform 3).

As described above, in this embodiment, one CRT is tilted with respect to the opposing operator and customer.
Display device 6 is installed in advance and C is used when sales data is registered.
When the display content of the RT display device 6 is switched to the registration screen to display and output the registered content and the subtotal registered this time, and when the detail display key FK is operated at the time of correcting the registered content, the CR is displayed.
Since the display content of the T display device 6 is switched to the detail screen and the registered detail data for one transaction held in the detail buffer 17-3 is displayed and output, one CRT display device 6 is operated by the operator. It can also be used as a display device for personal use and for customers. In this case, since only the minimum necessary data is displayed and output in relatively large characters on the recording surface, the readability for the operator is extremely good,
It is possible to immediately confirm the registered contents registered this time. Also, when the registered content is corrected, the detail screen is displayed, and the customer can see it together with the operator. Therefore, the operator can make a correction while interacting with the customer based on the detail screen, and trouble with the customer occurs. Can be effectively prevented.

In the above embodiment, when the registered contents are corrected, the case where the registration screen is switched to the detailed screen has been described as an example, but the present invention is not limited to the case where the registered contents are corrected.
If necessary, the detail display key FK may be operated to switch to the detail screen, or the switching to the detail screen may be interlocked with another function key.

[0021]

According to the present invention, one display device is installed in a tilting direction with respect to an operator and a customer facing each other, a registration screen for displaying the registration contents and the subtotal registered this time, and registration of one transaction. Since the contents screen is switched to the detailed screen for sequentially displaying the registered detailed data, one display device can be used for both the operator and the customer, and in addition to the operator in the registration process of registering sales data for one transaction. The necessary and appropriate data can be displayed to the customer, which is extremely practical in terms of cost and function.
