Description

[Detailed description of the invention] [Industrial application field] This invention relates to electronic cash registers.

[Prior Art] Conventionally, an electronic cash register has been provided with a keyboard 2, a display device 3, a receipt issuing port 4, and a journal inspection window 5 on the front surface of a housing 1, as shown in FIG. A storage section 7 for a drawer 6 is provided below. The display device 3 is provided with a line display 31 consisting of one line for displaying numerical values, for example, and a status display element 31 for displaying each status such as registration or error, and inside the housing 1, as shown in FIG. A printer mechanism 8 is provided in which a receipt printer and a journal printer are arranged side by side as shown in FIG. It is wound up by a roll 11 provided inside via a printer mechanism 8. The printed data of the journal paper 10 can be inspected through an inspection window 5 before it is wound onto the roll 11.

When product sales data is input from the keyboard 2, this cash register registers the sales data in an internal memory section and displays it on a line display 31, and also connects the printer mechanism 8 to a receipt printer and a journal. The sales data is printed on the receipt paper 9 and the journal paper 1° by operating the blinker.

[Problems to be Solved by the Invention] In such a cash register, when an operator wants to confirm certain data that has been previously registered, he/she must look at the data printed on the journal paper 10 through the journal inspection window 5 and search for it. However, if there is no data in the field of view from window 5, and it is between the printer and window 5, then the journal must be fed to bring the data into the field of view of window 5 before checking. Also, when it is past the window 5 and on the roll 11 side, it is impossible to check from the window 5, so in this case, you have to open the hood of that part of the housing 1 to see, and the journal paper is wastedly fed. There were some issues that required time and effort.

This invention was made to solve these problems, and provides an electronic cash register that eliminates the needless feeding of journal paper to check past data and allows for easy data confirmation. It is about providing.

[Means for Solving the Problems] As shown in FIG. 1, the present invention comprises a memory section a in which product sales data is registered, and a display data save area b having a plurality of records in which this sales data is sequentially saved. , an input pointer C that specifies the record of the latest display data saved in this save area b, and a record of the display data to be displayed on the line display device d among the display data saved in the display data save area b. A display pointer e that specifies the display pointer e, and a backward display key f that moves the record specified by the display pointer e to a record of display data registered before the display data saved in the record specified by the input pointer C. is provided, and the contents of the record in the display data area b designated by the display pointer e are displayed on the line display d.

In addition, the record specified by display pointer e is valid when it specifies a record of display data registered before the record specified by input pointer C, and the record specified by display pointer e is A return display key q is provided to move to a specified record.

[Operation] In the present invention having such a configuration, when product sales data is input, it is registered in the memory section a and also saved in one record in the display data save area b. And that record is input pointer C and display pointer e
The contents of the record are displayed on the display d. Then, by operating the backward display key f, the contents of the display pointer e are moved to specify the record in which the previously registered display data was saved.

At the same time, the display data of the record specified by the changed display pointer e comes to be displayed on the display device d.

Also, by operating the backward display key Q while the backward display key f is used to display the backward display, the record specified by the display pointer e changes to the record specified by the input pointer C, and the display d The display will also change. When the record content of the display pointer e finally becomes the record content of the input pointer C, the pressing of the return display key Q stops.

As shown in FIG. 4, the display device @25 is provided with a dot-type line display 251 and a status display element 252 that indicates the status of registration, code display, amount display, total display, etc.

As shown in FIG. 4, the RAM 23 includes an input pointer 2311, a display pointer 232, a data end pointer 233, a display data save area 234 having a plurality of records #O to #n, a display buffer 235, a print buffer 23s, A number buffer 237, working memory 23B, customer totalizer 23g, departmental totalizer 2310, transaction-specific totalizer 2311, and the like are provided.

The input pointer 231 stores data specifying the latest display data record saved in the display data save area 234, and the display pointer 23
2 stores data specifying a saved record of display data to be displayed on the line display 251 among the display data saved in the display data save area 234. Further, the data end pointer 233 stores data specifying the record in which the oldest display data among the display data saved in the display data save area 234 is saved.

The totalizer 239 for each customer stores the total amount obtained by adding up the product sales data registered for one customer.

The CPU 21 uses each key 271 to 27 of the keyboard 27.
The key operations shown in FIGS. 6 to 14 are performed manually by key B.

When the numeric key 271 is pressed manually, the numeric data is stored in the numeric buffer 237 as shown in FIG. 6, and the data in the numeric buffer is output to the line display 251.

When the person in charge key 272 is pressed manually, as shown in FIG. 7, if the person is already in the sign-on state, the set person in charge code is cleared and the person is placed in the sign-off state. Also, if you are in the sign-off state, place the number key 27! Check whether the responsible person code has been entered by
If it has been entered, set the responsible person code and sign/sign.
Turn on. Also, if there is no code input, an error will occur.

When the department key 273 is pressed manually, as shown in FIG. and outputs it to the line display 251. Note that if this key is operated without entering a code, an error will occur.

When the amount key 274 is pressed manually, as shown in FIG. 9, it is checked whether or not an amount has been input using the numeric key 271 in front of it, and if an amount has been input, the amount is stored in the display buffer 235. and perform display processing. When this display processing is completed, the amount is added to the customer totalizer 239, and the amount is added to the totalizer 231o for each department. Furthermore, print the department code and amount in the buffer 236.
The information is stored in the printer 29 and 30 and printed on receipt paper and journal phase rotation. Note that if this key is operated without setting the amount, an error will occur.

When there is a key input to the subtotal key 275, as shown in FIG. 10, it is checked whether a department has been registered beforehand, and if there is a department registration, the total amount of the customer totalizer 23s is stored in the display buffer 235. and perform display processing. Note that if this key operation is performed without registering the department in advance, an error will occur.

When there is key power for the current total key 275, as shown in FIG. 11, it is checked whether a department has been registered beforehand, and if there is a department registration, the total amount is accumulated in the transaction totalizer 2311. Further, the total amount is stored in the print buffer 236 and output to the printers 29 and 30. Finally, the customer totalizer 239 is cleared. Note that if this key operation is performed without registering the department in advance, an error will occur.

The display processing in the key processing of the amount key 274 and the subtotal key 275 is performed as shown in FIG. This first transfers the data in the display buffer 235 to the line display 25.
Output to 1. And input pointer 23! Updates the record specified by to the next record. That is, if the input pointer 23r has content that specifies record #1, it is updated to content that specifies record #2.

Next, it is checked whether the record designated by the updated input pointer 231 exceeds the maximum record #n, and if it does, the designation of the input pointer 231 is set to record #0. This is because the display data save area 234 is used endlessly.

Next, it is checked whether the record designated by the input pointer 231 is equal to the record designated by the data end pointer 233, and if they are equal, the contents of the data end pointer 233 are updated by one. This is because when the record specified by the input pointer is the record in which the oldest display data was saved, the latest display data is saved there again, so the contents of the data end pointer 233 are incremented by one. Then data end pointer 2
It is checked whether the record No. 33 exceeds the maximum record #n, and if it does, its contents are set as record #O. This is the same as for input pointers.

Next, input pointer 23! Display record of pointer 23
2, and the display data in the display buffer 235 is saved in the record indicated by the input pointer 231.

If the backward display key 277 is pressed manually, the contents of the display pointer 232 are first moved down by one to the previous record, as shown in FIG. As a result, it is checked whether the record of the display pointer 232 has become smaller than the minimum record #O, and if it has become smaller, the contents of the display pointer 232 are set to the maximum record #n.

Next, it is checked whether the contents of the display pointer 232 match the contents of the data end pointer 23, and if they match, the end of the data is displayed and the backward function is stopped. If they do not match, the display data of the record indicated by the display pointer 232 is transferred to the display buffer 23.
5 to display on the line display 251.

When the return display key 278 is pressed manually, the contents of the input pointer 231 and the display pointer 2 are displayed as shown in FIG.
32 and if they match, it is determined that there is no data to be returned and nothing is done. If they do not match, the record indicated by the display pointer 232 is moved up by one. Next, it is checked whether the record indicated by the display pointer 232 has become larger than record #n, and if it has become larger, the record indicated by the display pointer 232 is set as record #O. Furthermore, if the record has not become larger, the display data of the record indicated by the display pointer 232 is output to the display buffer 235 and displayed on the line display 251.

In this embodiment with such a configuration, the numeric key 271
The department code of the product being sold is entered using the and department key 273, and the sales amount of the product is entered using the number key 271 and amount key 274, thereby inputting sales data for one product. This input product sales data is registered in the departmental totalizer 2310 for each department and is added to the customer totalizer 23g. Also display buffer 123s
The data is displayed on the line display 251 via the print buffer 236 and printed on receipts and journals by the printers 29 and 30. Furthermore, this product sales data is saved in the record in the display data save area 234 indicated by the input pointer 231. At this time, the contents of the input pointer 231 are also transferred to the display pointer 232. In this way, each record #0 to ## of the display data save area 234 each time the department registration of product sales data is performed.
Display data is saved sequentially for n. When the department registration for one customer is completed and the subtotal key 275 is operated, the customer total on the customer totalizer 239 is displayed in the display buffer 235.
The data is displayed on the line display 251 via the display data save area 234 and saved as a record in the display data save area 234. When the customer receives money based on the total amount and operates the cash total key 276, the customer total in the customer totalizer 239 is registered in the transaction totalizer 2311 separately for each transaction such as a cash sale, and the customer total is Printer 29.3
0 is printed on the receipt and journal, and a receipt is issued. Further, the customer totalizer 239 is cleared and the system waits for the next customer's department registration.

When the next customer's department registration is started, the product sales data will be sequentially saved in the display data save area 234 following the previous customer's total data.

In the display data save area 234, when the number of records to be saved reaches record #n when product sales data and total data are saved in a record, the next record is saved to record #n.
It will now save to 0.

Of course, in this case, if there is old display data in the record to be saved, it is cleared and saved. And the newest record is the input pointer 231 and the display pointer 23
The oldest record is the record specified by data end pointer 233.

If the user wishes to confirm previously registered data while performing such a registration operation, the backward display key 277 is operated. By this key operation, the records specified by the display pointer 232 are moved back one by one and the contents of the records are displayed on the line display 251. However, the display 25
If the operation of the backward display key 277 is stopped when the display data that the user wants to confirm is displayed on the display 251, the display on the display 251 stops displaying that data, and the data can be easily and reliably confirmed. Moreover, since the line display 251 is used in this way to display and confirm the previously registered data, there is no need to confirm the data printed on the journal paper. There is no need to wastefully feed the data.

Furthermore, when the backward display key 27B is operated while the backward display key 277 is being displayed, the records specified by the display pointer 232 are returned one by one to the initial state, and the line display is displayed accordingly. The display data of 251 also changes. When the record specified by the display pointer 232 matches the record specified by the input pointer 231, this return display function is stopped, and the newest registered data is displayed on the line display 251. You can then continue to register product sales data.

In addition, in the above embodiment, in order to return to the original content that was displayed retrospectively using the backward display key, the display data is displayed one by one on the line display by operating the return display key, but the present invention is not necessarily limited to this. For example, after a certain period of time has passed after the operation of the backward display key is stopped, the display contents of the line display may be instantly returned to the latest data. can also be made unnecessary.

[Effects of the Invention] As detailed above, according to the present invention, previously registered data can be saved in the display data save area and displayed on the line display by operating the backward display key. To provide an electronic cash register in which journal paper is not needlessly fed to check data, and data can be easily confirmed.
