Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a registration system for electronic cash registers (hereinafter referred to as ECR), in particular, data is collected and stored for each category of registered products, and codes and unit prices are determined for each product. An ECR that has a price look amplifier (hereinafter referred to as PLU) registration function that allows you to register individual items by registering.

Regarding the registration method.

Generally, instead of traditional mechanical cash registers, E
CR, is in practical use.

In this type of ECR, in addition to printing out data registered for single items and calculating totals, it is also possible to classify various single items by department, and input department data in conjunction with single item registration to calculate sales points for each department. (number of times) and the cumulative amount are stored in memory, and the data is collected after the store closes or on a long-term basis and used as sales materials.

Additionally, since some stores have specific products that sell well, ECR has been implemented in which the product code and unit price for each best-selling product are set and stored in memory, and the unit price can be registered simply by entering the PLU code. ing.

In this way, ECR allows single item registration by simply registering the PLU code.

Conventionally, the department code to which the product belongs (i.e., the link destination corresponding to the department code) for each PLU code
is determined, and based on the PLU registration, the sales number of the department to which the product corresponding to the PLU code belongs is added, and the unit price is added to the cumulative amount of the corresponding department and stored.

Also, based on the PLU code registration, the registered PL
The number of sales items is set and stored for each U code.

However, if the data registered using the PLU code is stored in relation to the department data, it will be accumulated together with the amounts of other products, so the cumulative amount of the particularly necessary PLU code cannot be collected and stored separately. There was a problem.

The cumulative sales amount for each PLU code can also be calculated by multiplying the number of sales for each PLU code by its unit price, but the data based on PLU registration (i.e., the number of sales for each PLU code) is relatively short. Since it is updated every period, it was not possible to know the cumulative amount by PLU code over a long period of time.

In addition, if you want to know the total amount for each required PLU code, you have to calculate the number of times and the unit price, and if the ECR does not include such a calculation function, the operator must manually calculate it by mental calculation etc. There was an unavoidable annoyance.

Therefore, an object of the present invention is to provide a registration method for an ECR that allows registration data corresponding to some PLU codes that require individual item management to be collected and stored in the same manner as department registration data. It is to provide.

To summarize this invention, an empty storage area in which no department data is stored is provided in relation to a storage area for storing department data, and based on the registration of PLU codes that particularly require individual item management, Registration data corresponding to a code can be collected and stored in a free storage area in the same manner as department data.

FIG. 1 is a block diagram of one embodiment of the present invention.

In the figure, the ECR of this embodiment is a CPU 10 such as a microprocessor having an arithmetic processing function, a keyboard (described in detail in Fig. 2 below) 20, data registered with the keyboard 20, arithmetic results, etc. a display device 11 for displaying data, a printer 12 for printing data registered with the keyboard 20 and calculation results, or collecting and printing data as necessary, and a printer 12 for storing processed data of the present invention and for printing desired data. It consists of a memory 30 (details will be shown in FIG. 3 below) for storing settings.

FIG. 2 is an illustrative diagram of a specific operation section of the keyboard 20. As shown in FIG.

The keyboard 20 has numeric keys 21 including numbers 0.1 to 9, keys representing units of 1000, decimal point key, etc., and department codes "01" to "08" for single items corresponding to the unit price input using the numeric keys 21. a department key 22 for inputting information, a PLU key 23 for indicating that the numerical information entered by operating the numerical keys 21 is a PLU code, and a settlement mode key for instructing collection and printing of data collected and stored in the memory 30. Contains 24.

FIG. 3 is a diagram schematically showing the storage area of the memory 30.

In the figure, the memory 30 has data storage addresses for each key corresponding to department codes "01" to 1'-08J included in the department key 22, and each address stores the cumulative number of times for each department code. It has a department data storage area 31 including a storage area 31a for the number of times to store a total amount, and a total amount storage area 31b for storing the total amount for each department code, and a data storage address for each predetermined PLU code. Link destination storage area 32a that stores department link destinations
and number storage area 3 for storing the number of times for each PLU code.
2b and a unit price storage area 32c for storing unit prices for each PLU code, and an empty storage area provided in relation to the department data storage area 31 and not corresponding to any department key (not shown) 33 (indicates the case where the free storage area is at address 2) and the numerical key 2
1, a PLU register 35 that temporarily stores the specified PLU code, and a department code register 36 that temporarily stores the registered department code. It includes a flag (Fn) 37 that stores the fact that numerical information has been input, and an updater register 38 that temporarily stores the read cumulative amount for each department code.

Each address of the free storage area 33 is used as a multiplier and a totalizer, respectively.

In the illustration, the sum of the number of addresses in the department data storage area 31 and the number of addresses in the free storage area 33 indicates the PLU data storage area 3, and the PLU codes 01 to 08 and the department link destination are the same. However, this is not limited to cases where the

That is, a single address in the department data storage area 31 may correspond to a plurality of addresses in the PLU data storage area 32.

Alternatively, if there are many PLU codes that need to be collected and stored, such as the number of registrations and cumulative amount, the free storage area 3
3, or when there is a limit to the number of addresses in storage areas 31 and 33, do not use the higher code of the department key 22 and use the address of the storage area corresponding to that code as a free storage area. FIG. 4 shows a flowchart for explaining the invention in detail.

The table shows operation examples for each mode.

Next, the operation of this embodiment will be described by way of example with reference to FIGS. 1 to 4 and tables.

Single Item/Department Registration Mode First, a case will be described in which the price of a certain single item and its department information are registered and the department data of the single item is collected and stored.

First, when the unit price of a single item (for example, 50 yen) is entered by operating the numerical keys 21, the CPU 10 selects the PLU key 23 instead of the payment mode key 24 based on the fact that the first digit key was pressed. , it is determined that the key is not the department key 22 but one of the numeric keys 21 .

Then, it is determined whether the flag (Fn) 37 is logic "l" (that is, set), but if it is the first digit input by operating the numerical keys, the flag 31 is logic "0". After clearing the contents of the numeral register 34, shift the contents of the numeral register 34 to the left by one digit, move the numerical value "5" that has just been entered manually to the lowest digit of the numeral register 34, and set the flag 31 to logic rlJ. After writing , return to the previous step.

Next, when the numeric key 21 is operated and the next digit numeric value "0" is input, it is determined that the input is from a numeric key, and then,
After determining that the flag 37 is logical rlJ and shifting the contents of the numeral register 34 to the left by one digit, the numerical value "0" that has just been entered manually is moved to the lowest digit of the numeral register 34, and the contents of the numeral register 34 are shifted to the left. Write the logic rlJ and return to the key manual waiting step described above.

In this way, the numeric key 21 is stored in the numeric register 34.
The single item price (50 yen) entered by operating is stored.

The individual item price stored in the number register 34 is displayed on the display 11.

Next, the operator operates the department key 22 to enter the department code (for example, rolJ) of the single product for which the price of the single item has been input.
Enter.

Accordingly, the CPU 10 determines that the operated key is not the payment mode key 24 or the PLU key 23, but the department key 22.
It is determined whether the flag 31 is set or not.

At this time, if the registration operations are performed in a predetermined order, the logic rlJ is stored in the flag 37 by first registering the price of each item.

On the other hand, if the operator makes a mistake and operates the department key 22 before registering the price for each item, the flag 31 is logic "0", so it is determined that there is an error and an error is displayed.

Therefore, if registration operations are performed in a predetermined order, the CPU
0 determines that the flag 31 is logical "1", stores the department code (for example, rolJ) input by operating the all department keys in the department register 36, and stores the single item stored in the number register 34. The amount is transferred to the register 38 and stored.

Roughly speaking, the CPU 10 adds 1 to the sales number of the department code stored in the department code number storage area 31a corresponding to the department code (01) stored in the department register 36, that is, the number of registrations so far. According to
Increments the number of registrations for department code "01".

Further, the CPU 10 adds the current single item price (50 yen) to the cumulative amount (n yen) in the cumulative amount storage area 31b corresponding to the department code stored in the department register 36 (n+50
) to update the cumulative amount, write the logic rOJ to the flag 31, and return to the key human power waiting operation.

Thereafter, each time the numeric key 21 is operated to input the single item registration amount and the department key 22 is operated to input the department code, the above-mentioned operation is performed, and the number of registrations by department and the cumulative amount are displayed. will be stored cumulatively in the department data storage area 31.

PLU Registration Mode Next, a case in which single item registration is performed by inputting a PLU code and department information is stored in the department data storage area corresponding to the PLU code based on the single item registration is performed.

When performing PLU registration, the operator operates the numerical keys 21 to input a PLU code (for example, r02J) of a predetermined number of digits (for example, 2 digits), and then presses the PLU key 23.

The CPU 10 stores numerical information (PLU code r02J) in the numeric register 34 in the same manner as described above in response to the operation of the numerical keys, and then changes the flag 37 to logic "1" or not in response to the press of the PLU key 23. Determine whether or not.

At this time, since the PLU code (02) has been set and input first, after determining that the flag 31 is logic "1", the PLU code "02" stored in the numeric register 34 is input to the PLU register. 35 and store it.

Furthermore, the CPU 10 adds the registered number of times in the number storage area 32b corresponding to the registered PLU code "02JK" stored in the PLU register 35 by a value l, and
Department link destination storage area 3 corresponding to LU code “02”
The department link destination data (for example, department code r02J) stored in 1a is read out and stored in the department register 36.

Then, all unit prices (for example, 200 yen) stored in the unit price storage area 32c corresponding to the PLU code stored in the PLU register 35 are read out and transferred to the register 38.

Furthermore, the department code (
For example, add 1 to the number of sales of department code "02" and store it in the number storage area 31a of the department code in an updated manner, and register it to the cumulative sales amount of department code "02" stored in the cumulative amount storage area 31b. PL stored in 38
U Adds the unit price of the registered single item, and writes and stores the addition result in the cumulative amount storage area corresponding to the department code.

Then, after resetting the flag 31, the process returns to the key manual standby state described above.

In this way, registration processing is achieved when the PLU code and department code in PLU registration correspond.

Cumulative Mode Based on PLU Registration Next, we will discuss the case where the number of sales of a product corresponding to a specific PLU code and the cumulative amount thereof are collected and stored.

PLU codes that do not correspond to department codes (e.g. r09
J), in the same way as the PLU registration operation described above, operate the numerical keys 21 to input the PLU code "09", and then press the PLU key 23.

In response, the CPU 10 operates the numeric key 21 in the same manner as described above to store the input PLU code "09" in the numeric register 34, and then stores the PLU code "09" input in the numeric register 34 in response to the press of the PLU key 23. PLU stored in
The code "09" is transferred to the PLU register 35 and stored, and the number of times stored in the number storage area of the address corresponding to the PLU code "09" stored in the PLU register 35 is set to 1.
is added, and the department link destination corresponding to the PLU code is stored in the department register section.

At this time, the PLU code "09" is the department code "01".
j to “Does not correspond to any of 08j.

Therefore, the contents of the department data storage area 31 do not change.

By the way, here, a code "09" specifying the address 331 of the free storage area 33 is set as the department link destination corresponding to the PLU code "09".

Then, this code l'-09J will be in department register 3.
6 will be stored.

Also, the unit price (for example, 300 yen) of the PLU code "09" stored in the PLU register 36 is read out,
Stored in register 38.

Then, the multiplier provided at address 331 of the free storage area 33 specified by the code "09" stored in the register 36 is incremented by 1, and the unit price of 300 yen stored in the register 38 is added to the totalizer. Ru.

As described above, if there is no department code that specifies the registered department corresponding to the PLU code, the PLU registration is performed in a predetermined free storage area 330 times, independent of the normal corresponding department data storage area 31. PLU number on the instrument,
Make the cumulative amount memorized.

As a result, for a specific product for which a corresponding registration department code is not set (for example, a product with PLU code "09"), the sales data of that product that is registered only through PLU registration is uniquely stored in the free storage area 330 times. It is possible to manage individual products by reporting the free storage area using the payment mode described later.

Settlement mode In the settlement mode, data stored in the department data storage area 31 and free storage area 33 is collected and printed, and data stored in the PLU data storage area 32 by PLU code is collected and printed. There are three modes for totalizing and printing all the data in the department data storage area 31, PLU data storage area 32, and free storage area 33.

Of these three payment modes, PLU data storage area 3
The mode in which the data in No. 2 is aggregated and printed (i.e., PLU report) is frequently performed in a relatively short period of time, and is used to print the aggregated data in the department data storage area 31 and the free storage area 33 (i.e., department report), or to print out the totals in the department data storage area 31 and the free storage area 33, or to print out the totals in the department data storage area 31 and the free storage area 33, or to print out the totals in the department data storage area 31 and free storage area 33. Aggregation printing is performed over a relatively long period of time.

First, the case of a PLU report in which data in the PLU data storage area 32 is totaled and printed will be described.

When performing a PLU report, the operator must press the numeric key 21.
After inputting the code "02" representing the PLU report by operating , the payment mode key (ZR, P) 24 is pressed.

In response to this, the CPU stores the report code "02" inputted by operating the numeric key 21 in the number register 34, and then, based on the fact that the settlement mode key 24 was pressed, the flag 31 is set to logic. It is determined that the value is "1", and the content of the numeric register 34 is determined to be "02", and the process proceeds to the PLU report operation.

In the PLU report operation, first store the numerical value [J in PLU[/ register 35 and write the first PLU code "0".
1”.

Then, the PLU code specified by register 35 is “OI
The data in the department link optical storage area 32a, frequency storage area 32b, and unit price storage area 32c at the address corresponding to J are read out, and the department link destination data of the specified PLU code "01" is printed, and the number of times and unit price are printed. Print and record.

Furthermore, the CPU 10 uses the specified PLU code "Ol".
The total amount of PLU code "01" is calculated by multiplying the number of times and the unit price, and the total amount is printed and recorded by the printer 12.

After that, the CPU 10 clears the number of PLU codes "Ol" specified by the stored contents of the register 35, adds 1 to the contents of the register 35, and sets the PLU code l'-02J to be printed next in the register 35. The PLU code to be tallied and printed is incremented by storing the PLU code, and then it is determined whether the PLU data is complete (for example, whether the contents of the register 35 are the maximum number of PLU codes or not).

If all of the PLU data has not been tabulated and printed,
By repeating the above-mentioned operation, it is repeated until the total printing of all the PLU data is completed. When all the total printing is completed, the flag 31 is reset, and then the key manual power standby state is returned.

In this way, the total printing of data stored at each address in the PLU data storage area 32 is performed in the order of the addresses.

Next, the case where the data in the department data storage area 32 and the free storage area 33 provided in relation to the department data storage area are totalized and printed will be explained.

The operator operates the numerical keys 21 to input the code "01" representing the department report, and then presses the settlement mode key 24.

In response, the CPU 10 stores the report code "01" in the number register 34, and then determines that the flag 31 is logical "1" in response to the depression of the settlement mode key 24, and stores the report code "01" in the number register 34. It is determined that the content is not "02" but "01" and the process proceeds to the department data report operation.

That is, store the numerical value rlJ in department register A, specify the first department code "01", and store department register 3.
The designated department code “o” specified by the store contents of 6.
After reading out the number of times of department code "01" and the cumulative amount and having the printer print and record them, the number of times of department code "01" and the cumulative amount are cleared.

Subsequently, the CPU 10 adds 1 to the contents of the department register 36 to increment the department code to be total printed.

Then, it is determined whether all the department data has been completed.

The determination as to whether the department data is complete or not is determined, for example, by determining whether data at all addresses in the department data storage area 31 and free storage area 33 have been read.

If the total printing of all department data has not been completed, repeating the above operation will print out the department code "O".
The number of times of "1" to "08" and their respective cumulative amounts are tallied and printed, and the number of times and their cumulative amounts for each PLU code determined to correspond to the air storage area 33 are tallied and printed.

When all the department data are totaled and printed, the CPU 10 determines that the flag 37 is logical "1", resets the flag 37, and then returns to the key manual standby state.

In this way, the data stored in the department data storage area 31 and the free storage area 33 are tallied and printed.

On the other hand, when all the data stored in the storage areas 31 to 33 are to be totalized and printed, this can be accomplished by simply pressing only the payment mode key 24 without operating the numerical keys 21.

When the payment mode key 24 is pressed, the CPU sets flag 3.
1 is not the logic "1", first totalizes and prints the data at all addresses in the department data storage area 31 and free storage area 33, then determines that the flag 31 is the logic rOJ and performs the above-mentioned process. By performing the same operation as the total printing of each address of the PLU data storage area 32, the total printing of the data of all the storage areas 31 to 33 is achieved.

As described above, according to this embodiment, an empty storage area that does not correspond to a department key in the department data storage area is used to store PLU codes that require data collection and storage similar to department data. is associated with the free storage area, and if the PLU code belongs to a department based on the registration of the PLU code, the number of times and the cumulative amount are stored in relation to the corresponding department data, without being associated with the department. If the code needs to be collected as data similar to the department registration process for each PLU code, it is stored in a free storage area, thereby collecting and storing the number of times corresponding to the PLU code registered as a PLU and its cumulative amount. It has the advantage of being able to

In addition, since empty addresses in the department data storage area are used to store the required number of PLU codes and amounts, there is an advantage that this can be done without adding any special memory and can be done at low cost.

Furthermore, data based on PLU registration is aggregated and printed over a relatively short period of time, but departmental data is aggregated and printed over a relatively long period of time. It also has the advantage of being able to aggregate and store the number of times and cumulative amount over a long period of time.

As described above, according to the present invention, there is provided an ECH registration method that can collect and store the particularly required number of PLU codes and their cumulative amount based on the PLU registration process, and does not require a special memory for this purpose. It will be done.
