Description

[Detailed Description of the Invention] <Technical Field> The present invention relates to an electronic cash register (hereinafter simply referred to as ECR) having a department-specific registered cumulative amount storage means for storing the registered cumulative amount for each department for each transaction. .

<Prior art> In general, an ECR is equipped with a total memory such as a department-specific registered cumulative amount memory that stores the registered cumulative amount of transaction products by department, and these total memories are updated every time there is a registration to store the registered cumulative amount. An overflow occurs when exceeds the memory size. Conventionally, as a countermeasure against this overflow, the overflow is ignored.

When reporting (printing) the tally memory, an overflow mark is printed in the print field of the memory where an overflow has occurred.

To prohibit (lock) monetary registration when the total memory overflows.

The following means were being devised.

However, in these conventional devices, since all measures are taken after an overflow occurs, there is a problem that the contents of the total memory are not accurately retained due to the overflow. Also,
In order to solve this problem, a method has been proposed in which when an overflow occurs, the sum is continued to be accumulated in the second aggregation memory (Japanese Patent Application Laid-open No. 1983-1972-1).
116165), however, this configuration required a second aggregation memory for each department, resulting in a considerable increase in cost.

<Purpose of the Invention> This invention has been made in view of the above, and it is possible to perform settlement processing when it is determined that there is a high possibility that the total amount will exceed the upper limit of the total memory and the memory will overflow when registering a transaction product. The purpose is to provide an ECR that can be configured at low cost, and prevents overflows caused by exceeding the upper limit of total memory.

<Means for Solving the Problems> The present invention provides an electronic cash register having a section-specific registered cumulative amount storage means for storing the registered cumulative amount for each department for each transaction. Maximum registered cumulative amount storage means for storing the upper limit amount a; Maximum registered amount per transaction storage means for storing the upper limit c of the registered amount for one transaction; A value a−b obtained by subtracting the departmental registered cumulative amount b stored in the departmental registered cumulative amount storage means from the upper limit amount a of the registered cumulative amount and the one transaction stored in the one transaction maximum registered amount storage means a registered cumulative amount comparison means for comparing and determining the upper limit c of the registered amount in each department; It is characterized by comprising: a payment processing means for performing processing;

<Operation> In this invention, the maximum registered cumulative amount storage means stores in advance the upper limit a of the registered cumulative amount per department, and the one transaction maximum registered amount storage means stores the upper limit c of the registered amount in one transaction. be done. Further, like the known ECR, the department-specific registered cumulative amount b is stored in the department-specific registered cumulative amount storage means. This departmental registered cumulative amount b is updated every time the registration process is performed.

With a, b, and c stored as described above, a-b and c are compared and determined for each department, and a
- If there is even one department where b is smaller than c, settlement processing will be performed.

By doing this, overflow can be prevented.

This ECR includes an input section 1 that includes a numeric key N, a department key D, and a function key F, and a key input determination section 2 that receives key signals from the input section 1 and determines which key is pressed. , a CPU 4 that receives output signals from the key input determination unit 2 and executes various processes according to various processing programs stored in advance in the ROM 3, a RAM 5 that stores various data processed by this CPU 4, and a RAM 5 that stores various data processed by this CPU 4. CPU4
a display section 6 that displays various data processed by the
Similarly, a printing unit 7 that prints various data processed by the CPU 4 on a receipt or journal;
A mode switch 8 that defines various handling modes for how to use the ECR, a mode information temporary storage section 9 that temporarily stores the mode information selected by the mode switch 8, and one of the input sections 1 mentioned above. The key input detection section 10 inputs and stores the mode information temporarily stored in the mode information temporary storage section 9 in the area a of the CPU 4 when it detects that a key is pressed.

As shown in FIG. 2, the RAM 5 includes an area D that stores department information for each transaction product, a unit price area P (p1 to pn) that stores the unit price of each transaction product, for example,
A registered cumulative amount area B (b1 to bn) stores the registered amount by department, and a transaction cumulative amount area T (t1 to bn) stores the registered amount for each transaction by department.
tn), for each transaction registration, a total area It has a maximum registered cumulative amount area A that stores the upper limit of the registered cumulative amount, and a single transaction maximum registered amount area C that stores the upper limit of the registered cumulative amount in one transaction.

Next, with reference to FIG.
We will explain the procedure for setting data such as ECR's cumulative registration amount by department and maximum registration amount per transaction.

FIG. 3 is a flowchart showing the ECR data setting procedure.

At step n1 (hereinafter, step ni is simply referred to as ni), the operator first switches the mode switch 8.
Select the desired mode by operating . Next, at n2, this mode information is temporarily stored in the mode information temporary storage section 9. With n3 and n4,
When the operator presses any of the keys on the input unit 1, the key input detection unit 1 is detected via the key input determination unit 2.
0 detects this key input and causes the mode information stored in the mode information temporary storage section 9 to be input and stored in area a of the CPU 4. received this mode information
The CPU 4 determines which mode this mode information indicates, and based on this determination result,
Select and set processing routines such as maximum registration amount setting, unit price setting, and registration stored in ROM3 in advance.
Various data inputted thereafter are processed according to this processing routine (n5 to n8). If the mode stored in area a is the unit price setting mode in n5, select the unit price setting routine in ROM3 in n7, and then press the numeric key N of input section 1 in n9.
is operated to input the unit price information of the corresponding department to the CPU 4 via the key input determination section 2. Next, at n10,
The operator presses a specific department key to indicate to which department the unit price information input at n9 belongs. Upon receiving this instruction, the CPU 4 selects and specifies the corresponding area pi of the RAM 5 corresponding to the designated department, sets the above-mentioned unit price information in the corresponding area, and prints this print information on a receipt or journal in the printing section 7 ( n11, n1
2). At n13, it is determined whether the unit price setting is finished or not.
If the process is not completed, the operations from n9 to n13 described above are repeated, and unit price information corresponding to all departments is input and set. On the other hand, in n5, the mode stored in area a is the maximum registered amount, such as the maximum registered cumulative amount, which is the upper limit of the registered cumulative amount in one department, and the maximum registered amount, such as the maximum registered amount in one transaction, which is the upper limit of the registered cumulative amount in one transaction. If it is determined that the mode is the maximum registered amount setting mode, the maximum registered amount determination routine in the ROM 3 is selected at n6. Then n1
At step 4, the address of the memory where the maximum registered amount data is to be stored is specified using the numerical key N of the input unit 1. Next, in n15, enter either the maximum registered cumulative amount for one department or the maximum registered amount for one transaction, which is the maximum registered amount data, and then in n16, press a specific key of function key F to send the maximum registered amount to CPU4. Provide data setting instructions. When the CPU 4 receives this instruction, it specifies area A of the RAM 5 if the input amount is the maximum registered cumulative amount for one department, and area C if it is the maximum registered amount for one transaction, and stores the amount data. The settings are stored in the designated area and printed on the journal or receipt by the printing unit 7 (n17, n18). n1
In step 9, it is determined whether both the maximum registered cumulative amount for one department and the maximum registered amount for one transaction have been set and stored in areas A and C, respectively, and if both have not been set, n
Repeat steps 14 to n18. In this way, the unit price,
The maximum registered cumulative amount for one department and the maximum registered amount for one transaction are set in advance.

Next, the ECR registration processing procedure will be explained with reference to FIG.

FIG. 4 is a flowchart showing the ECR registration process.

If it is determined in n5 that the area information stored in area a is in the registration mode, first the quantity data of the traded product is input using the numerical key N, and the quantity data is entered by pressing the department key D. The CPU 4 determines which department the data belongs to (n20 to n22).

At n23, the corresponding area pi of department i determined by the CPU 4 is designated, and at n24, the unit price data set for that area is read out. This read unit price data is multiplied by the previously input quantity data, and the result of the calculation is added to the amount previously stored in the corresponding area ti of area T in RAM 5, and the total amount is It is temporarily stored in the summation area X (n25 to n27).

It is determined whether the cumulative transaction amount of department i stored in area If the amount exceeds the maximum registration amount, please use n29.
A tightening instruction is given by CPU4 and the process moves to n33. n2
8, if it is determined that the cumulative transaction amount of department i stored in total area X is less than the maximum registered amount for one transaction, the cumulative transaction amount stored in area The updated value is stored in area ti and printed on a receipt or journal by the printing unit 7 (n30, n31).

At n32, it is determined whether or not the transaction registration is finished. If it is finished, the process moves to n33. If it is not finished, the procedure from the input of the quantity described above is repeated to register all the traded products.

In n33, a closing operation is performed by pressing a specific key among the function keys F, and the cumulative amount of one transaction by department stored in area ti is added to the amount stored in area bi, and the total amount is The value is stored as an updated value in area bi, and printed on the receipt or journal in the printing unit 7 (n34~
n36).

Next, the deposit amount from the customer is displayed on the numerical key N,
and is input to the CPU 4 by operating the storage key in the function key F (n37, n3
8). Upon receiving this input, the CPU 4 calculates the amount of change for the customer, then prints it on the receipt etc.
Issue a receipt for the transaction (n39,
n40).

Next, the CPU 4 reads out the cumulative registered amount for each department stored in area B of the RAM 5 and the maximum registered cumulative amount for one department after each memory stored in advance in area A, and The calculation is performed for each department, and it is determined whether the calculation result exceeds the maximum registered amount for one transaction stored in area C (n41, n42). area A and
If it is determined that the difference with bi does not exceed the maximum registered amount for one transaction, the process moves to n43. On the other hand, if it is determined that the number exceeds the limit, the corresponding departmental data is printed in the printing unit 7 at n44, and then the process moves to n43.

At n43, it is determined whether the above process has been performed for all departments. If it is determined that the process has not been performed for all departments, the above process is repeated until it has been performed for all departments. If n43 determines that the above process has been carried out for all departments, n45
Then, in the above judgment process, it is determined whether there is at least one department where the difference A-bi between the cumulative transaction amount by department and the maximum registered cumulative amount for each department does not exceed the maximum registered amount for one transaction, and if there is not one, then That is, if the difference A-bi exceeds the maximum registered cumulative amount for one transaction in all departments, the process returns to n3 again and waits for input.

If the difference A-bi does not exceed the maximum registered amount for one transaction in even one department, there is a risk that an overflow will occur in that department, so a settlement instruction is given to the operator at n46.

The operator who received the payment instruction issues a payment command to the CPU 4 by pressing a specific key among the function keys F, and according to this command, the CPU 4
After reading the data stored in each area of the RAM 5 and printing it sequentially in the printing unit 7 to issue a payment slip, the process returns to n3 and enters the mode input waiting state (n4
7-n51).

The amount obtained by subtracting the registered cumulative amount of the department at the time of the transaction from the preset maximum registered cumulative amount of one department, that is, the remaining amount that can be registered after the transaction is less than or equal to the maximum registered amount of one transaction. If there is at least one department, there is a risk that the corresponding memory will overflow during the next registration in that department, so please immediately perform the settlement process.
This prevents the risk of overflow during the next registration in the relevant department.

<Effects of the Invention> As described above, according to the present invention, the upper limit of the registered cumulative amount for each department and the upper limit of the registered amount for one transaction are preset and stored in a predetermined area, and the corresponding The registered amount is deducted from the upper limit of the cumulative registered amount for each department, and there is at least one department in which the difference, that is, the remaining amount of the registered amount that can be registered, is less than or equal to the upper limit of the registered amount for one transaction. In such cases, there is a risk of overflow in the relevant department during the next registration, so by performing the settlement process immediately, overflow can be prevented, and registration errors due to overflow can be reliably avoided during the next registration. At the same time, the risk of overflow in each department is determined using the upper limit of the registered amount in a single transaction for each department, compared to the case where the upper limit is set for each department. ,
The processing program can be simplified, reducing processing time, and has advantages in program design. Since the input settings can be made based on the actual performance of the cash register, the memory capacity of this type of cash register that stores cumulatively registered amounts for each department can be utilized as effectively as possible without overflowing.
