Description

[Detailed Description of the Invention] [Objective of the Invention] (Industrial Application Field) The present invention provides a system for storing electronic cash registers (ECRs) in a group of electronic cash registers (ECRs) that can mutually exchange data. This invention relates to an electronic cash register system that enables centralized management of the business contents of the cashier in charge.

(Prior art) Recently, in supermarkets and large stores, multiple ECRs are connected online.
Systems that allow mutual data exchange are being adopted.

(Problem to be solved by the invention) However, even in the case of such a system, each
Because each ECR had to manage the business operations of the cashier in charge of that ECR, that is, manage money, sales, and productivity, it was not possible to check such management data in real time when necessary.

Also, if the cache is moved to another ECR,
Each ECR required memory for the number of cachers using that ECR, which resulted in an expensive problem.

The present invention was made in view of the above problems, and by centrally managing the business contents of the cashier in charge of each cache register in the parent cache register, the child cache register only has one memory. This allows multiple cashiers to be placed in rotation, which enables efficient cache management, reduces the memory of child cache registers, and prevents the inconvenience of one cashier opening multiple cash registers at the same time. The purpose of this invention is to provide an electronic cash register system that can

[Structure of the invention]

(Means for Solving the Problems)) The electronic cash register of the present invention is capable of mutually exchanging data between a plurality of cash registers, or any one register (hereinafter referred to as parent). A management table memory for each cashier that stores the business status of each cashier for each cashier number of a plurality of cashiers in charge of the cash register, and operations related to money management, productivity management, sales management, etc. for each cashier number. A cache for each cache is provided for storing data, and a cache for one cache is provided for storing business data processed by the registration operation of the cache in charge of the child register in other registers (hereinafter referred to as child registers). A business memory is provided, and in the parent register,
When the opening data of the cache in charge of the child register is received from the child register, the child register is made available for use according to the business status of the cache-specific management table memory corresponding to the cache number of the child register, and the child register is activated. When the closing data of the cache in charge of the child register is received from , the child register is set to an unusable state according to the business status of the cache management table memory corresponding to the cache number of that cache, and the cache business memory of the child register is The present invention is characterized in that data is aggregated in the cache-specific business memory for each cache number.

(Function) When opening a child register, the present invention inputs the cache number of the cacher in charge of the child register, sends this cashier number together with opening data to the parent register, and the parent register receives this cache number and opening data. At that time, a registration operation is started to mark the cache in a usable state in accordance with the business status of the cache-specific management table memory corresponding to that cache number. Then, in the child register, the business data processed by the registration operation of the cacher in charge of this child register is aggregated and stored in the cashier business memory in the child register.

After that, when the cacher in charge of the child register closes the child register, the child register sends the station closing data, and the parent register stores the cashier-specific management table memory corresponding to the cache number to which this station closing data was sent. Depending on the status, the child register becomes unusable, and the unusable child register sends the business data processed by the registration operation to the parent register. In the register, business data related to money management, productivity management, sales management, etc. is compiled for each cashier number in a cashier-specific business memory that is stored for each cashier.

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

FIG. 1 is a block diagram showing the entire system. In the figure, R ₁ to _{R 10} are ECRs with the same structure except for some memories, and are connected in a loop via transmission lines (ADB) such as address bus and data bus.
It is now possible to exchange data with each other.
Here, R ₁ to R ₉ are child ECRs, and R ₁₀ is a parent ECR.

Figure 2 shows the child ECRs R ₁ to R ₉ and the parent ECR
FIG. 2 is a block diagram showing the configuration of _R10 . In the figure, 1 is a keyboard, and on its top surface are a number key 2, a department key 3, a payment key 4, a receive key 5, a hanging key 6, a correction key 7, a return key 8, a coupon S key 9, a coupon V key 10, In addition to a discount key 11, total key 12, and cash key 13, first and second control switches 14 and 15 are arranged, respectively.
The first control switch 14 can perform operations such as "power off", "registration (REC)", "inspection (X)", and "payment (Z)" depending on the key held by the cashier in charge of the second control switch 14. The control switch 15 allows the manager to selectively perform the operations of ``manager lock (MGR)'' and ``pickup (PU)'' depending on the key held by the manager.
Reference numeral 16 denotes a keyboard circuit constituted by a key matrix circuit, which generates key signals and business signals corresponding to the key positions when various keys on the keyboard 1 or control switches 14, 15 are operated. central processing unit [CPU]
Give to 17.

The CPU 17 has a built-in temporary register 17a, and a display 19 via a display circuit 18, a clock device 20, a read-only memory [ROM] 21, and a random access memory [RAM] 22. Printers 24 are each connected via a printer control circuit 23. The ROM21 has the above-mentioned "registration"
In addition to processing programs for various tasks such as "inspection,""payment," and "setting," there are transmission programs for exchanging data with each ECR. Also,
The RAM 22 includes a sales/productivity management memory 31a and a money management memory 31 in the case of child ECRs R ₁ to _{R 9} .
cache business memory 31, cache number memory 32, and other data collection memory 3 consisting of
3 is the parent ECR R ₁₀ : cache management table memory 41, sales/productivity management memory 42a for each cashier, and money management memory 4 for each cashier.
A cashier-by-cashier business memory 42, a cache number memory 43, and an other data collection memory 44 each consisting of 2b are provided.

As shown in FIG. 3, the cache-specific management table memory 41 stores cache numbers (00001) to 1 for all caches in charge of each ECR.
(00010) is registered in advance, and flags F ₁ to _{F 10} store the business status of the cashier corresponding to the cache number (00001) to (00010).
are provided for each. Each flag F ₁ ~ _{F 10}
As shown in FIG. 4, it consists of 8 bits, the first judgment bit (B ₁ ) determines whether the pick-up process is in progress, and the second judgment bit (B ₂ ) determines whether the station is open. whether the station is closed or whether it is in use according to the third judgment bit (B ₃ );
The fourth determination bit (B ₄ ) is used to store whether or not the payment has been completed. In addition, sales/productivity management memory 42a for each cashier
In this example, the data related to the number of customers, number of sales items, number of product registrations, total sales amount, etc. shown in Figure 5 are as follows:
It is now possible to total by cache number (00001) to (00010). Further, the cashier money management memory 42b stores data regarding specific items (cash, checks, coupons S) related to transactions such as sales, payments, receipts, etc. shown in FIG. 6, using cashier numbers (00001) to ( 00010). In addition, each child ECR R ₁
The sales/productivity management memory 31a and money management memory 31b of ~ _R9 can aggregate data regarding items similar to those shown in Figures 5 and 6 for one cashier in charge of child ECRs _R1 ~ _R9 . It's becoming like that.

Next, the effect will be explained. If the child ECR R ₁ is to be used by the cache with the cache number (00001), first enter the cache number (00001) in the child ECR R ₁ using the numeric keys 2, and then press the cache key 13. Then the child
ECR R ₁ stores the input cashier number (00001) in temporary register _17a according to the flowchart in FIG.
Cashier number stored in 7a (00001)
Inquiry data is sent as to whether or not the cashier can be opened. On the other hand, when the parent ECR R ₁₀ receives the opening availability data from the child ECR R ₁ according to the flowchart in FIG. Check the state of the corresponding flag _F1 . At this time, the second and fourth flags _F1
If the judgment bits (B ₂ ) (B ₄ ) are “0”, it means that the station can be opened, so the “affirmative” response data is
In any other state, it is impossible to open a station, so after returning "negative" response data to child ECR R ₁ , if the response data is "affirmative", it corresponds to the cache number (00001). Write flag F ₁ as “60”. Then, in child ECR R ₁ ,
When receiving response data from parent ECR R ₁₀ ,
It is determined whether the response data is "affirmative" or not, and if the response data is "affirmative", the cashier number (00001) stored in the temporary register 17a is set.
is stored in the cache number memory 32 and set to a usable state. At this time, the child ECR R ₁
The display on the display 19 changes from, for example, "LOG" to "0". Therefore, the cashier in charge of this child ECR R ₁ starts the product registration operation after seeing that the display on the display 19 has become "0".

When you start a registration operation, the various data processed by the registration operation will be stored in the sales and sales data in child ECR R ₁ .
Productivity management memory 31a, money management memory 31b
and other data collection memory 33 are classified and aggregated for each item. At this time, the sales/productivity management memory 31a also stores the total time that the station has been opened by the clock device 20, the usage time spent on registration operations, and the drawer opening time.

After that, if the cashier in charge of the child ECR R ₁ wants to close the child ECR R ₁ , for example, to take a break, he presses the "0" key and then presses the cashier key 13. Then, the child ECR R ₁ sends the station closing permission data to the parent ECR R ₁₀ , that is, the cache number (00001) stored in the cache number memory 32 of the child ECR R ₁ , according to the flowchart in FIG. 8a. Sends inquiry data as to whether the cache can be closed. On the other hand, in the parent ECR R ₁₀ , the child
Upon receiving the station closure permission data from ECR R ₁ , the status of flag F ₁ corresponding to the cashier number (00001) is checked from the cashier-specific management table memory 41. At this time, the second judgment bit (B ₂ )
is set to "1", but whether or not the third judgment bit (B ₃ ) is "0" (unused state after the processing based on the registration operation has been completed) is determined by the fourth judgment bit (B 3 ). B ₄ ) is "0" (the cashier-specific sales/productivity management memory 42a and the cashier-specific money management memory 42b of the cashier number (00001) are not cleared), and determine whether they are "0". If it is "0", it means that the station can be closed, so "affirmative" response data is returned to the child ECR R1, and if it is in any other state, "negative" response data is returned to the child ECR _R1 . Then, in child ECR R ₁ , parent ECR R ₁₀
When response data is received from , it is determined whether or not the response data is "affirmative", and if the response data is "affirmative", the sales/productivity management memory 31a
and the data in the money management memory 31b to the parent ECR
After sending the data to _R10 , the cashier number (00001) stored in the cashier number memory 32 is cleared and the station is closed. On the other hand, in the parent ECR R ₁₀ ,
After the data sent from the child ECR _R1 is totaled in the cashier-specific sales/productivity management memory 42a and the cashier-specific money management memory 42b corresponding to the cache number (00001), the flag _F1 is written as "40".

Thus, in the parent ECR R ₁₀ :
In addition to centrally managing the opening and closing of the cashiers in charge of ECR R ₁ to _{R 9} and parent ECR R ₁₀ , the business data processed by each cashier is stored in the sales/productivity management memory 42a for each cashier and the cash management memory for each cashier. 42b, the data is totaled for each cache. On the other hand, the data for each cashier number compiled in the sales/productivity management memory 42a for each cashier and the money management memory 42b for each cashier are stored in the child ECRs R ₁ to _{R 9} and the parent ECRs.
Any ECR R ₁₀ can be output as an inspection report. For example, if you want to output a money management inspection report for the cashier number (00001) on child ECR R ₂ , in that child ECR R ₂ ,
After switching the first control switch 14 to "inspection" and inputting the report number (08) and cashier number (00001) for outputting the money management inspection report using the numeric key 2, the parent ECR
The data in the cashier-specific money management memory 42b corresponding to the cashier number (00001) of _R10 is read out and printed by the printer 24 of the slave ECR _R2 , and a money management inspection report as shown in FIG. 12, for example, is output. be done. On the other hand, for example the parent ECR R ₁₀
, after switching the first control switch 14 to "inspection" and inputting the report number (15), a card with the cashier number in the open state and the cashier number in the closed state printed will be displayed as shown in Fig. 11. A player list report is output. Therefore, after confirming the cashier number in the closed state from this cashier list report, the cashier accounts for the cashier with the cashier number in the closed state. Cashier settlement is performed on child ECRs R ₁ to R 9 and parent ECRs in the same way as inspection, according to the flowcharts in Figures 9 and ₁₀ .
Can be done with any ECR R ₁₀ . In this case, after switching the first control switch 14 to "Settlement", if you enter a cashier number (00001), the parent ECR R ₁₀ will correspond to that cashier number (00001) from the cashier management table memory 41. The cashier-specific sales/productivity management memory _42a corresponds to the cashier number (00001) only when the second determination bit ( _B2 ) is "0".
The data in the cash management memory 42b for each cashier is outputted as cash settlement reports (sales management settlement report, money management settlement report, and productivity management settlement report) shown in FIGS. 13a, b, and c, for example. At this time, when the cash is settled, the flags _F1 to _F10 corresponding to the cashier numbers for which the cash has been settled are written to "CO", and thereafter the sales/productivity management memory 31 of each ECR _R1 to _R10 is written.
The cashier with that cashier number is
ECR R ₁ to R ₁₀ cannot be used.

In addition, in the parent ECR R ₁₀ , if you switch the second control switch 15 to "Pick Up" and then specify an activated cache, for example, the cache with the cache number (00001), the child ECR R that is in charge of that The registered data of ₁ is sent to the parent ECR R ₁₀ , and the cashier-specific sales/productivity management memory 42a and the cashier-specific money management memory 42b of the cashier number (00001) are sent to the parent ECR R 10.
will be added to

〔Effect of the invention〕

According to the present invention, when a parent ECR receives open data from a child ECR for a cache in charge of that child ECR, the child ECR is used according to the business status of the cache-specific management table memory corresponding to the cache number of that cache. While the state is
When the opening data of the cache in charge of the child ECR is received from the child ECR, the child ECR is made unusable according to the business status of the cache management table memory corresponding to the cache number of the child ECR, and the cache operations of the child ECR are performed. Since the memory data is aggregated by cache number into the cache-specific business memory, the parent
In a system that allows an ECR to centrally manage the opening and closing of the cashiers in charge of child ECRs, as well as aggregating business data related to money management, productivity management, sales management, etc. processed by each cashier, each child ECR need only have enough memory for one cache, and each child
An ECR can be assigned a number of caches according to the number of memories per cache in the parent ECR, reducing the memory of each child ECR, and allowing one cacher to open two or more cache registers at the same time. Inconveniences can be prevented, and compared to the conventional method in which cash management is performed using each cash register, it is possible to eliminate the effort and complexity associated with cash management, and the necessary management data can be checked at any time. Management data can be checked at will, and cashier staffing or ECR allocation can be done effectively.
