Description

[Detailed Description of the Invention] This invention is an electronic cash register (hereinafter referred to as ECR).
Regarding this, in particular, for example, when a number of single item registration information that matches the number of items of single item registration information that can be registered in memory is input, the single item registration information that has been registered up to that point will be processed even if the total processing is not performed. Regarding ECH.

Generally, an ECR is equipped with a memory having a storage area (hereinafter referred to as a data buffer) for storing a certain number (for example, 48 items) of single item registration information for products purchased by customers. It is being

However, some customers may purchase more than 48 items per person.

In such a case, only 48 items can be registered in the data buffer, so when the registration of the single item registration information for the 48th item is completed, a warning is automatically sounded by a buzzer etc. to inform the operator that the data buffer memory is full. is informing you.

Upon hearing the alarm, the operator operates the total key to total the single item registration information for 48 items registered in the data buffer, and then causes the printer to sequentially print the single item registration information on the receipt.

After that, input the single item registration information for the remaining products and when the registration of all products is completed, operate the total key again and print the single item registration information for the remaining products on the receipt in the same manner as described above. ing.

Therefore, even though there is only one customer, if the number of purchased products exceeds 48 items, the total key must be operated twice, which complicates the operator's operations.

Furthermore, two receipts are issued to one customer, causing an inconvenience as if products purchased by two customers were registered.

Incidentally, recently, an ECR has been developed that can collectively correct the previously registered single item registration information when incorrect single item registration information is input when inputting the single item registration information.

In addition, in supermarkets and the like, when the store becomes crowded, it takes time for customers to register the products they have purchased and pay for them. ) and the operator (cashier) who makes the payment.

In such a two-person ECH, a data buffer is provided to store single item registration information of a plurality of customers.

After the checker registers the single item registration information of each purchased item of the customer, when a summation operation is performed, the single item registration information of that customer is printed by the printer.

The cashier then performs a settlement transaction operation based on the total display.

In such a two-person ECH, when the registration of the first customer is completed, the individual item registration information of that customer registered in the data buffer is not cleared unless the cashier performs payment processing for that customer.

Therefore, when the second customer's single item registration information is registered, the second customer's single item registration information is registered following the first customer's single item registration information, so the total may exceed 48 items.

In such a case, an alarm will automatically sound, informing the checker that no further registration is possible.

The checker heard the alarm and had to wait until the cashier had finished checking out the previous customer.

Therefore, in the present invention, the number of single item registration information corresponding to the predetermined number of items that can be registered in the data buffer is 1.
To provide an ECR that, when registered by one customer, can continuously register the single item registration information of the remaining products without performing a totaling operation, and can print all the single item registration information on one receipt. That's true.

To summarize this invention, in a two-person electronic cash register that is separated into a registration department and a payment department, each time the individual item registration information of the products purchased by a customer is registered, the number of items is counted and calculated. When the numerical value reaches a value corresponding to the number of items of single item registration information that can be registered in the data buffer, the single item registration information that was read before the total information from the data buffer is printed and read out without performing the total operation. The configuration is such that new single item registration information can be registered in the storage area of the data buffer in the same number as the number of single item registration information items.

The present invention will be described in more detail below with reference to embodiments shown in the drawings.

FIG. 2 is a layout diagram of the keyboard of the checker side ECH in one embodiment of the present invention.

In the figure, various counters 221 are storage areas for storing the number of times products have been registered for each department, and various totalizers 222 are storage areas for storing the total amount for each department.

Further, storage areas 223 to 23 serve as data buffers for storing, for example, individual item registration information of multiple items purchased by three customers and their total prices.
1 is provided.

Note that this data buffer is not limited to the areas 223 to 231 for three people, but may have storage areas for more people.

The storage area 232 of the read address register stores the addresses of the data buffers 223 to 231 when the printer 25 of the cashier side ECR 2 prints the single item registration information stored in the data buffers 223 to 231 on a receipt. It is something.

The write address register 233, which serves as a second address counting storage means, specifies the address for writing single item registration information into the data buffers 223 to 231, and the single item registration information is input from the keyboard 10 of the checker side ECR 1. The address is incremented each time.

A registration start address register 234 as a first address counting storage means stores data buffers 223 to 231.
The address of the first registered information area (first item registration information area) 223 is stored.

A storage area 235 as a data buffer counter 1 stores the number of items of single item registration information stored in the data buffers 223 to 231, and a storage area 236 as a data buffer counter 2 stores a data buffer provided for each customer. 223 to 225° 226 to 2
28 and the number of items of single item registration information stored in any one of 229 to 231.

FIGS. 6A and 6B are flowcharts for explaining the operation of an embodiment of the present invention.

Next, the specific operation of one embodiment of the present invention will be described with reference to FIGS. 1 to 6B.

Note that in FIGS. 6A and 6B, steps (abbreviated as SP in the figures) 1 to 29 are executed by the CPU.
21 indicates operations to be executed according to the program, and other operations are based on human operations or judgments.

First, with reference to FIG. 6A, the checker is on the checker side BC.
The operation when registering single product registration information using RI will be described.

When the checker side ECR 1 is powered on, the CPU 21 performs initial processing and sets the address of the first item registration information storage area 223 of the first person in the registration start address register 234 of the memory 22.

The checker operates the keyboard 10 of the checker side ECR 1 to input the single item registration information of the product purchased by the first customer.

That is, after inputting the single item registration information using the numeric keypad 104, the department code is input using the department key 107.

Then, in step 1, the CPU 21 reads the address set in the write address register 233, loads it into an accumulator (not shown), and stores the address in the memory 22.
The address of the area 223 is specified.

Then, in step 2, the CPU 21 stores the above-mentioned single item registration information entered manually in the area 223.

Thereafter, the CPU 21 increments the write address register 233 in step 3 to update the address.

Further, by storing the single item registration information of the first item in the area 223, the CPU 21 updates the contents of the data buffer counters 235 and 236 in steps 4 and 5, respectively.

The checker determines whether all the products purchased by the first customer have been registered.

If all of the products have not been registered, determine whether or not it is necessary to make a bulk correction, and if there is no need to make a bulk correction, follow the same procedure as described above to register the first customer's purchase 2.
Manually enter the individual item registration information for the item.

Then, the CPU 21 repeats the operations of steps 1 to 5 and stores the input single item registration information of the second product in the area 224 of the memory 22.

If there is a registration error or a customer requests the return of a registered product, the checker operates the batch correction key 101 in order to collectively correct the single product registration information of the first customer registered so far. do.

More preferably, the batch correction key 101 and other keys ( For example, digit release key 103
) may be sequentially operated to enable batch correction.0 The CPU 21 determines in step 6 whether or not a key manual signal is given from the batch correction key 101.

When the CPU 21 determines that the batch correction key 101 has been operated, the CPU 21 determines in step 7 whether or not the single item registration information is stored in all of the data buffers 223 to 225, that is, the count value of the data buffer counter 236 is It is determined whether the number of items matches the number of items that can be registered in 225.

If the CPU 21 determines that they match, it ends the operation to prohibit batch correction, and if they do not match, it presses the batch correction key 1.
It is determined that 01 has been operated.

Then, in step 8, the CPU 21 transfers the address of the area 223 stored in the registration start address register 234 to the write address register 233 and stores it therein.

Therefore, the write address register 233 is again in the area 2.
Specify the address of 23.

In step 9, the CPU 21 subtracts the count value of the data buffer counter 236 from the count value of the data buffer counter 235, and stores the result in the data buffer counter 235.

That is, the CPU 21 uses the data buffer 229, for example.
231 stores the previous customer's single item registration information, and the cashier side ECR 2 may not have finished the payment for that customer, so the data buffer counter 235
Leave the number of items for that customer in , and subtract only the number of items to be corrected in bulk.

Further, in step 10, the CPU 21 resets the data buffer counter 236 to the initial state.

After the checker completes the bulk correction operation, the checker rekeys the regular single item registration information, and if the customer requests a return, it manually inputs the single item registration information of all other products except for the returned item. .

Therefore, in areas 223 to 225, the first customer's erroneous registration information is corrected and genuine single item registration information is stored.

Further, the CPU 21 uses data buffer counters 235, 2
36, the quantity corresponding to the number of registered items is counted.

The checker repeats the registration operation in the same manner as described above, but in step 11, the CPU 21 checks whether the count value of the data buffer counter 235 has reached a certain value, that is, whether the data buffers 223 to 231 are full. Determine whether or not there is.

If it is full, the CPU 21 issues an alarm using a buzzer (not shown) or the like in step 12 to inform the checker that no more registration is possible.

The checker hears the alarm and sends the cashier to the checkout process (
(described later in FIG. 6B), the data buffer 22
3. Wait until... is cleared.

If it is not full, it returns to the initial state to allow the next registration.

When the checker registers the single item registration information of all products of the first customer in the data buffer 223..., the subtotal key 109
operate.

Accordingly, the CPU 21 calculates the total of the single item registration information stored in the data buffers 223 . . . and stores the sum in the total area 225.

Furthermore, since the total data is stored in the total area 225, the number of items stored in the data buffers 223, . . . has increased, so the CPU 21 increments the data buffer counter 235 in step 13.

Furthermore, when the CPU 21 has finished storing the first customer's single item registration information in the data buffers 223 to 225, it resets the data buffer counter 236 in step 14.

Further, in step 15, the CPU 21 updates the address of the write address register 233 and sets the address of the total buffer 225.

In step 16, the CPU 21 stores the data buffer 2.
The single item registration information registered in 23 to 225 is totaled and stored in a total buffer 225.

In step 17, the CPU 21 updates the write address register 223 and specifies the address of the next area 226.

Further, in step 18, the CPU 21 controls the area 22.
Write address register 23 that stores address 6
3 is stored in the registration start address register 234.

That is, the registration start address register 234 had previously stored the address of the first item registration information storage area 223 for the first person, but by operating the subtotal key 109, the registration start address register 234 has stored the address for the first item registration information storage area 223 for the second person. The address of area 226 will be stored.

Then, in the same manner as described above, when all the item registration information purchased by the second and third customers is inputted manually, the CPU 21 stores the input item registration information in the data buffers 226 to 231. .

Next, with reference to FIG. 6B, an explanation will be given of the operation when the cashier pays for the products purchased by the first customer.

At this time, the read address register 232 stores the address of the area 223.

The CPU 21 enters the checker side EC in step 19 (0).
Based on the input signal from the keyboard 10 of R1, the subtotal key 109 is operated to determine whether or not the tightening operation has been completed.

If not, in step 20 it is determined whether the count value of the data buffer counter 236 is a constant value.

If the value is not a constant value, the CPU 21 returns to the initial state and waits. If the value is a constant value, the CPU 21 reads out the address of the area 223 stored in the read address register 232 in step 21 and loads it into the accumulator. .

At the same time, the CPU 21 in step 22
It is determined whether single item registration information is stored in .

If it is not stored, the CPU 21 uses the checker side EC.
The machine waits until the single item registration information is entered manually from R1 and the tightening operation is performed.

If data is stored in the area 223, the CPU 21
is the data buffer counter 235 in step 23.
Subtract "-1" from.

Then, in step 24, the CPU 21 reads the registered data from the data buffer 223, and in step 2
In step 5, it is determined whether the data is total data or not.

If it is total data, the display 11 is displayed in step 26.
However, if it is not total data, it is printed by the printer 25 in step 27.

The CPU 21 reads the read address register 2 in step 28.
32 is updated and set to the address of area 224.

Furthermore, in the same manner as described above, the data buffer counter 236 is decremented in step 23, and the data in the area 224 is printed by the printer 25.

In this manner, when the data buffer counter 235 counts the number of items of single item registration information that can be registered in the data buffers 223 to 231, all of the single item registration information is printed by the printer 25.

On the other hand, when the CPU 21 reads out the total data in the area 225, the CPU 21 causes the display 24 to display a subtotal in step 26.

Thereafter, the cashier operates the total key 208 of the cashier side ECR 2 to perform a transaction operation.

In step 29, the CPU 21 issues a receipt by printing the total data, the deposit data of the amount deposited from the customer, and the change data when the customer pays a high-value bill using the printer 25.

In this way, the series of operations when the cashier performs a transaction operation is completed.

Further, in the above-described embodiments, the present invention is applied to an ECR having a batch correction function, but it goes without saying that the present invention may also be applied to a normal ECR that does not include a batch correction function.

As described above, according to the present invention, when single item registration information is registered for the number of items that can be registered in the data buffer, all the single items registered in the data buffer are automatically Registration information can be printed on the receipt.

After that, it is possible to register the single item registration information for the remaining products, so no matter how many items a single customer has purchased, all the single items purchased by that customer can be recorded on one receipt with one total operation. Registration information can be printed, eliminating the inconvenience of issuing two receipts to one customer.

In addition, when the number of individual item registration information is not registered for the number of items that can be registered in the storage area allocated for each customer, it is now possible to make batch corrections, so even if the previous customer's payment has not been completed. Even if there is, the single item registration information registered by the next customer can be corrected all at once.
