Description

The present invention relates to an electronic cash register used in a restaurant or the like.

(B) Conventional technology In restaurants such as restaurants, when a customer orders food etc., the order details are registered in the electronic cash register for each customer, and when the customer finishes the meal and pays for the registration. There is a place where a method of printing the contents and issuing as a receipt is adopted. Therefore, even if the customer makes additional orders several times before making the payment, all the order contents are registered and it is possible to make a bill at the time of payment (see, for example, JP-A-55-88162).

(C) Problems to be Solved by the Invention When printing the registration contents at the time of payment, conventionally, a method of printing in the order of registration as shown in FIG. 7 and an individual product as shown in FIG. One of the methods of printing after totaling was used, but it is difficult to see because the former method does not summarize each product, and the latter method makes it easy to see because each product is aggregated. However, there is a problem that it is not possible to know which product the discount is for because the discounts are also summarized.

(D) Means for Solving the Problems The present invention provides a keyboard provided with various keys, a means for storing attributes of each key, a means for totaling and storing input data for each same item, and an input It is composed of means for storing the connection relation of the stored data and control means for controlling to sequentially read out and print the data having the connection relation from the stored data.

(E) Operation Since the present invention is configured as described above, when the registered data is printed, the printing is performed for each product and the data related to the products are sequentially read and printed.
Printed as shown in FIG. 9, the correspondence such as discounts becomes clear.

(F) Example An example of the present invention will be described below with reference to the drawings.

FIG. 1 shows a circuit configuration of an electronic cash register of the present invention. (1) is a control circuit composed of a microprocessor, and the entire control is performed according to a program in a program memory (2) in which a processing program is stored in advance. Control

(5) is a data memory for storing data input from the keyboard (3) or data processed by the control circuit (1). As shown in FIG. 3, data relating to each key of the keyboard (3) is stored. An area (5A) for storing, two buffer areas (5B) (5C) for temporarily storing input data, and four areas (5D) (5E) for storing processed data and acting as pointers for addressing memory. ) (5F) (5G) and other data storage area (5H).
A) further comprises an area (5I) for storing data for distinguishing whether the key is main or sub, and an area (5J) for storing product name data in the case of the product division distinguishing key (3B).

(6) is a registration memory for storing registration data for each customer. As shown in FIG. 4, (M ₁ ) to (M _N ) is composed of a plurality of memory blocks, and one customer's order is placed in one block. It is configured to store data. And registration memory (6)
As shown in Fig. 5, each block of each customer is configured to be able to store data by dividing the input data into a plurality of items on one line. (6A) indicates whether the line is in use or not. This is an area in which data indicating whether to use is written. When used, "1" is written, and when not used, "0" is written. (6B) is an area that stores data that distinguishes whether the line data is main or sub, (6C) is an area that stores data indicating the type of key, and (6D) is data that indicates a unit price or unit. An area to be stored, (6E) is an area in which unit price data is added and data showing an amount of money is stored, and (6F) is an area in which data showing the number of cases is stored, and the number of cases is added. (6G) is an area for storing data indicating the presence / absence of sub-lines to be linked, and "0" is written when there is a sub-line and there is no "1". (6H) is an area for storing the linked LINE number.

Reference numeral (7) is a display for displaying data input from the keyboard (3) or data processed by the control circuit (1). A printing device (8) prints data input from the keyboard (3) or data processed by the control circuit (1), and performs receipt printing and journal printing.

Next, the operation of the present invention having such a configuration will be described.

First, the product name and the attribute data of the main or sub key are input and stored in the product department key (3B) prior to use. For the sake of explanation, “Coffee” is assigned to the section 1 key (3D) and section 2
The key (3E) is set to "hamburger", the department 3 key (3F) is set to "potato", and the department 4 key (3G) is set to "tomato" as shown in FIG. Also department key (3D) (3E)
(3F) is a main key, and data (M) indicating the main key is set in the area (5I) of the data memory (5),
Since the department key (3G) is used as a subkey, data (S) indicating the subkey is set in the area (5I).
For the other keys of the keyboard (3), the attribute of the key and the product name of the department key (3B) are similarly stored in the area (5A) of the data memory (5).

Next, the operation will be described based on the specific key input shown in FIG.

First, before inputting order data, a code number for identifying a customer is input, and a memory block for registering data in the registration memory (6) is designated. Then, when ordering coffee, enter the price "250" with the numeric keypad (3A) of the keyboard (3) and operate the department 1 key (3D), the control circuit (1) that detected the key data Data corresponding to the department 1 key (3D) is read from the area (5A) of (5), and it is detected in step (S1) whether the key is a main key or a sub key. Now, the department 1 key (3D) is set as the main key, and the data entered in the main buffer area (5B) of the data memory (5) at the step (S2) (unit price entered by the numeric key and department key Write the item corresponding to "etc." Next, in step (S3), set 1 to the LINE pointer (5D) of the data memory (5), and then in step (S4) based on the value of the LINE pointer (5D), the LINE-1 area of the registered memory (6). Check (6A) to detect whether it is in use, but since it is unused at the beginning, step (S4)
Then, the process proceeds to step (S7) and the area (6
Data is written in A), (6B), (6C), and (6D), and then in step (S8), the area (6
E) Add data to (6F). As a result, LINE- in the registration memory (6) is operated by the key operation shown in FIG. 6 (a).
Data is written in 1 as shown in FIG.

Next, the coffee is discounted by 10%, and when the key operation shown in FIG. 6 (b) is performed, the "%" key (3
H) is set as a subkey, so step (S10)
Then, the input data is written in the sub-buffer area (5C) of the data memory (5). Then, in step (S11), the LINE pointer (5D) of the data memory (5) is set to "1", and in step (S12) the registered memory (6) is set.
It is judged whether or not it is in use by checking the area (6A) of LINE-1 of LINE-1. However, LINE-1 is in use by the key operation of the above-mentioned FIG. 6 (a), and next step ( S1
Proceed to 3) and main buffer (5B) of data memory (5)
And the data in the areas (6C) and (6D) of the registered memory (6) are compared to determine whether they are the same main data.
Since it is the same now, the procedure proceeds to step (S15), and it is determined whether or not there is a linked sub line by checking the area (6G) of the registered memory (6). However, since it is not linked now, the procedure proceeds to step (S19) and the data memory Set "1" to the LINE2 pointer (5F) in (5). Then, in step (S20), the LINE-1 of the registered memory (6) is checked to determine whether or not it is in use. However, since LINE-1 is already in use, the operation proceeds to step (S21) and the LINE2 pointer is incremented. Then, the process proceeds to step (S20) as "2", and LINE-2 of the registered memory (6) is stored based on the value "2" of the LINE2 pointer (5F).
It is determined whether or not is in use, but LINE-2 is not used and the process proceeds to step (S22), and data indicating that there is a subline in the LINE-1 area (6G) based on the instruction of the LINE pointer (5D). As a LINE-N ₀ that writes "1" and links the value "2" of the LINE2 pointer (5F) to the area (6H).
11 Write as shown in the figure. Then, in step (S23), the items in the sub-buffer (5C) of the data memory (5) and unit price data are stored in the LINE-2 area (6) of the registration memory (6).
A) to (6D) are written, and in step (S24), the amount of money and the number of items of data are added to the registration memory (6) areas (6E) and (6F), and the processing ends. As a result, when the key operation of FIG. 6 (b) is completed, the data is written in the registration memory (6) as shown in FIG.

Next, when the key operation shown in FIG. 6 (C) is performed,
Similar to the case of the key operation of (a), step (S1)
(S2) (S3) (S4) (S5), but since it is not the same main data in the judgment of step (S5), it advances to step (S6) and increments the LINE pointer (5D) to step (S4). It is determined whether or not LINE-2 is in use, but since it is in use, it proceeds to step (S5) and determines whether or not it is the same data. However, since they are not the same, the process proceeds to step (S6) again, increments the LINE pointer (5D) to set "3", and returns to step (S4). Then LINE pointer (5
LINE-3 instructed by D) is not in use, so step (S
Proceed to 7), and in the same way as the key operation of FIG. 6 (a), in steps (S7) (S8), the LINE-3 of the registration memory (6)
Data is written as shown in the figure. Next, when the key operation shown in FIG. 6 (d) is performed, the discount key (3I)
Is set as a subkey, the process proceeds from step (S1) to step (S10), and data is written to the registered memory (6) by the same process as described above, but the same main data is written in step (S13). Can be found on LINE
It is when the data of the pointer (5D) is "3", and until then, the processing of steps (S12) (S13) (S14) is repeated. If LINE-3 is found to be the main data in step (S13), the process proceeds to step (S15), but there is no subline link in LINE-3 and the process proceeds to step (S19). LINE
Since it is in use up to -3, the value of the LINE2 pointer (5F) becomes "4" and the step (S2
The process proceeds from step 0) to step (S22), and the data is written in the same manner as described above, whereby the data is written in the registered memory (6) as shown in FIG.

Next, when the key operation shown in FIG. 6 (e) is performed, the process proceeds from step (S4) to step (S5), and LINE-1 determines that it is the same main data. Proceed to S8) and add to the registered memory (6). As a result, the amount of money in LINE-1 of the registration memory (6) becomes "500" and the number of cases becomes "2" as shown in FIG.

After that, the same processing is performed in the key operation of FIGS. 6 (f) (g) (h) (i) (j), and the data is written in the registration memory (6) as shown in FIG. Be done.

Next, when the key operation of (k) is performed following the key operation of FIG. 6 (j), it means that the order was made by attaching tomatoes to the hamburger, and the department 4 key (3G) was the department 2 key (3E). ) Is set as a subkey, the process proceeds from step (S1) to step (S10) and the same processing as described above is performed, but at this point the same main data as the main data stored in the main buffer (5B) Is detected in step (S13) when the LINE pointer (5D) is "3", and until then, steps (S12) to (S14).
The process of is repeated. Therefore, if it is detected that LINE-3 has the same main data, the process proceeds to step (S15).
It is detected whether or not the sub-line is linked to -3. Since LINE-4 has already been linked, go from step (SS15) to step (S16) and link from the LINE-3 area (6H). Read LINE-N ₀ and set it to the SUBLINE pointer (5G) of the data memory (5).
Therefore, in this case, "4" is set. Next, in step (S17), the value of the SUBLINE pointer (5G) is set in the LINE pointer (5D), the registered memory (6) pointed to by the LINE pointer (5D) is checked in step (18), and the same sub data It is determined whether or not. Now the LINE pointer (5D) is "4"
Since LINE-4 is not set to the same, the process proceeds to step (S15) and it is determined whether there is a subline linked to LINE-4. However, since there is no subline linked to LINE-4, the process proceeds to step (S19) and the same processing as described above is performed. At this time, step (S20)
(S21) is processed, but since LINE-6 is already in use, the LINE2 pointer (5F) is set to "7" and LINE is set.
When -7 is specified, from step (S20) to step (S2
Go to 2). And the LINE specified by the LINE pointer (5D)
LINE2 pointer (5F) value "7" in area -4 (6H)
Write as INK-N ₀ and LINE in steps (S23) (S24)
By writing the data to -7, the registration memory (6) becomes the state shown in FIG. When all data is input in this way, LINE of the registration memory (6)
LINE-2 and 5 are linked to -1, and LINE to LINE-3
It can be seen that -4 and 7 are linked.

Even if the customer divides the order into several times, the final
Data is registered in the registration memory (6) as shown in FIG.

Although not described in the above description, by assigning a code number to the customer and distinguishing them, if the memory blocks (M ₁ ) to (M _N ) of the registered memory (6) are distinguished by the identification of the code number, a plurality of them can be obtained. Data can be registered in the memory blocks (M ₁ ) to (M _N ) of the registration memory (6) by distinguishing the customers.

Finally, when the customer pays the customer's code number and operates the total key (3J), the control circuit (1) that detects the key signal causes the memory corresponding to the customer in the registered memory (6). The data is read from the block and the printing device (8) is controlled to print on the receipt and the journal. That is, as shown in FIG. 19, first, in step (S100), the LINE pointer (5D) of the data memory (5) is set to "1", and the registration memory (6) is searched. Then, in step (S102), the area (6B) of the registered memory (6) is checked to determine whether it is main data or sub data. If it is main data, the process proceeds to step (S104), but if it is sub data, step (S103). ), Increment the value of the LINE pointer (5D) and repeat until main data is detected. Since LINE-1 is the main data at first, the process proceeds to step (S104) to read the contents of LINE-1 and print it as shown in FIGS. 9 (a) and 9 (b). Next, in step (S105), the value of the LINE pointer (5D) is set in the LINE1 pointer (5E). So now the LINE1 pointer (5
"1" is set in E). Then step (S106)
Proceed to step 1 to search the registered memory (6) based on the value of the LINE1 pointer (5E) and determine whether or not there is a linked subline. However, since LINE-1 is linked to LINE-2, The process proceeds to step (S107) and "2" of LINE-N ₀ read from the area (6H) of LINE-1 is set in the LINE1 pointer (5E). And the LINE1 pointer (5E)
Step 2 to read the LINE-2 data
In 8), print as shown in Fig. 9 (c) and (d). When printing is completed, the process returns to step (S106) to detect whether or not there is a sub line linked to LINE-2. Since LINE-5 is linked, the process proceeds to steps (S107) (S108) and is the same as above. Then, print the LINE-5 data as shown in Fig. 9 (e). When printing of LINE-5 is completed, the linked sublines are detected in step (S106).
Since it is not linked to 5, the process proceeds from step (S106) to step (S103), the value of the LINE pointer (5D) is incremented, and the process proceeds to step (S101). As a result, LINE −
2 is searched, but since LINE-2 is a subline, proceed from step (S102) to step (S103) LINE
Set the pointer (5D) to "3". Since LINE-3 is the main line, proceed to step (S104) and Figure 9 (f)
Print the LINE-3 data as shown in (g). Then, in the same manner as described above, steps (S105) (S106) (S107)
By the process of (S108), the sub line linked to LINE-3 is printed.
Is linked, printing is performed as shown in FIGS. 9 (h) and (i). And then the LINE-6 data is the 9th
When it is printed as shown in FIG. 6 (j), when it is detected that the LINE-8 of the registration memory (6) is unused in step (S101), the process proceeds to step (S109) and the area of the registration memory (6) ( 6E) data is added to obtain the total step (S1
In step 10), printing is performed as shown in FIG.

(G) Effect of the Invention As described above, the electronic cash register of the present invention is configured so that data related to products is aggregated and printed at the time of printing, thereby issuing a receipt that is very easy to understand. It is something that can be done and is most suitable for use in restaurants and the like.
