Description

DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention relates to an electronic cash register suitable for use in a store that sells merchandise by weight.

[Prior Art] Generally, an electronic cash register has a memory section in its storage section for accumulating sales data of sold products by department code for classifying the products. The number of items sold and the sales amount are accumulated by department code in the department memory. Further, in electronic cash registers of stores where a plurality of operating managers (cashiers) work in shifts, a memory for each cashier is formed to accumulate sales data of sold products for each cashier.

On the other hand, stores that sell products by weight use electronic price scales in addition to the electronic kisesh register. This electronic price scale has the unit price per unit weight of the weighed and sold product set in the storage section, and by measuring the weight of the weighed and sold product in the weighing section, the sales amount can be calculated from this measured weight and the corresponding unit price. The product name and sales amount are printed on a receipt and issued. Then, the clerk looks at the issued receipt and operates the keyboard of the electronic cash register to input the department code and sales amount of the weighed product. Then, the sales amount etc. entered by key personnel are accumulated by department code or by cashier.

[Problems to be solved by the invention] By the way, with conventional electronic cash registers, it is possible to commit fraud such as entering a lower amount than the actual amount and embezzling the difference when entering the sales amount of a sold product. It is. However, even if such fraud occurs,
Since there were no ambiguous points in the contents of the departmental memory or cashier's memory, it was difficult to discover them even after inspection or payment. In particular, the prices of products sold by weight vary each time they are sold, and only the sales clerk manually enters the keystrokes while looking at the receipt, making it easy for the above-mentioned fraud to occur.

Such fraud can be discovered by aggregating the sales of a specific department code that the cashier does not know by each cashier, separately managing the accurate sales of that specific department code, and collating the data on both sides. . If it becomes easier to detect fraud, this type of fraud will naturally stop happening.

SUMMARY OF THE INVENTION Therefore, the present invention aims to provide an electronic cash register that can aggregate sales data for a specific department code for each cashier and prevent unauthorized cashier input.

[Means for Solving the Problems] As shown in FIG. 1, the electronic cash register of the present invention is provided with a specific department memory A and
A specific code setting means B is provided for setting at least one of the department codes, and a memory C for each person in charge is provided for accumulating sales data of products of the specific department code set by this setting means B for each person in charge of operation. At the same time, a specific department code determining means E is provided for determining whether or not a sales product whose sales data is input from the input section is a product with the above-mentioned specific department code. In this case, a manager-specific memory updating means F is provided for updating the sales data in the manager-specific memory C based on the sales data of the product.

[Function] If the electronic cash register is equipped with such a method, the sales data of products with the specific department code set in the specific department memory is accumulated in the cashier-specific memory, so this is aggregated. At the same time, by managing accurate sales data for products with the specific department code and comparing the two, it is easy to detect fraudulent input by the cashier.

[Embodiment] Hereinafter, an embodiment in which the electronic cash register of the present invention is adopted in a store that sells merchandise by weight will be described with reference to the drawings.

FIG. 2 is a block diagram of the electronic cash register. In the figure, a CPU (Central Processing Unit) 11 has a built-in arithmetic circuit, etc., performs predetermined processing based on various input data, and also executes programs such as programs for executing tasks via a path line 12. ROM (read only memory) 13 that stores fixed data, and RA that stores variable data such as input data and calculation data.
M (random access memory) 14 is operated. In addition, a keyboard controller 16 inputs and converts key signals from a keyboard 15 for inputting sales data of sales products, etc., and various operations such as "registration", "precision", "inspection", "setting", and "cashier minus". An input board 18 that inputs a command signal from the mode switch 17 to instruct the execution of a mode, a display controller 20 that drives a display section 19 that displays sales data, etc., and displays characters, etc. corresponding to the display data; A printer/drawer controller 23 that drives and controls a dot printer 21 for printing sales data on a journal and also opens a drawer 22 for storing cash, etc.
, and a clock circuit 24 that measures the current year, month, day, hour, and minute are connected to the CPIJll via the pass line 12.

As shown in FIG. 3, the keyboard 15 has [00J
rOJ ~ "9" numeric key 31, "01" ~ "15"
In addition to product registration keys such as the department key 32 for inputting department codes for classifying products up to ``, and the deposit/cash key 33 for declaring registration details for cash payments, there are also keys for sign-on and sign-off. Function keys such as a person-in-charge key 34 used when setting a specific department code and a specific key 35 used when setting a specific department code are provided. Further, the mode switch 17 is provided on the keyboard 15.

As shown in FIG. 4, the RAM 14 includes a departmental memory 41 having a measurement flag F1 for each department code and a sales area R1 for accumulating the number of sales items and sales amount for each department code, and a departmental memory 41 for each cashier Nα. A sign-on flag F2, a total sales area R2 that accumulates the total number of sales items and the total sales amount of sales items for each cashier number, and a specific department sales area R3 that accumulates the number of sales items and sales amount of sales items that belong to a specific department code for each cashier number. A separate cashier memory 42 is formed. The measurement flag E1 is set to "1°' if the product of the corresponding department code in the setting operation is a product sold by weight, and is set to 0" if it is a product normally sold. The sign-on flag F2 is set to "1" when the cashier of the electronic cash register performs the sign-on process in the registration process, and is reset to "O'' when the cashier performs the sign-off process.

As shown in the figure, the RAM 14 also includes a number register 43 that temporarily stores number data, a totalizer 44 that adds up the number of sales items and sales amount during the transaction, and a specific department where a specific department code is set. A memory 45 and a flag memory 46 for storing a responsible person flag F3 corresponding to the responsible person key 34 are formed.

The CPU 11 then executes the key processing shown in FIGS. 5 to 7 in response to key signals from the keyboard 15. That is, when the specific key 35 is input, as shown in FIG. 5, it is first determined whether or not the "setting" business mode has been commanded by the mode switch 17. Then, any mode other than "Settings" business mode will be an error, and "Settings"
In the business mode, after confirming that the number data is stored in the number register 43, this number data is stored in the specific department memory 43 as a specific department code, and the process ends.

When the person in charge key 34 is input, the process is executed according to the job commanded by the mode switch 17, as shown in FIG. If the "registration" business mode is commanded, after confirming that the number data is stored in the number register 43, the flag memory 4
At step 6, it is determined whether the responsible person flag F3 is set to ``1''. If it is not set to 111 II, it is determined that it is a sign-on process, and the sign-on flag F2 corresponding to the cashier NO in the cashier-specific menu 42 is set to "1" with the number data set as cashier N0. Furthermore, the responsible person flag F3 is set to "1" and the process ends. On the other hand, in Pl, the responsible person flag F3 is “
If it is set to 1'', it is determined that it is sign-off processing, and the number data is stored in the cashier-specific memory 42 in the order of the cashier.
The sign-on flag E2 corresponding to the above cashier Nα of
After confirming that is set to "1", the cashier NQ, the data in the total sales area R2 and the data in the specific department area R3 corresponding to the cashier NG in the cashier-specific memory 42 are printed out on the receipt. will be issued. Thereafter, the corresponding sign-on flag E2 and responsible person flag F3 are each reset to 140 II, and the process ends.

When the department key 32 is input, processing is executed according to the job commanded by the mode switch 17, as shown in FIG. When the "registration" business mode is commanded, after confirming that the numeric data is stored in the numeric register 43, the department code entered manually with the key in R2 is set in the specific department memory 45. It is determined whether the account is a specific department account. Then, if it is a specific department code, the sign-on flag F2 of the cashier-specific memory 42 updates the specific department sales area R3 corresponding to the cashier number set to "1".

That is, the sales amount is adjusted based on the number data as the sales amount, and the sales score is updated by "+1". On the other hand, P2
This process is not performed unless the department code input in is a specific department code. Next, the total sales area R1 corresponding to the corresponding department code in the department memory 41, the total sales area R2 corresponding to the sign-on flag "1" in the cashier memory 42, and the totalizer 44 are updated, respectively.

In other words, the set number data is added to each sales amount as the sales amount, and each sales point is updated by +11.

Further, the department code, number of items sold, sales amount, etc. are displayed on the display unit 19, and the printer 21 prints them out on a receipt, and the process ends.

In the electronic cash register of this embodiment configured in this way, first the store manager switches the mode switch 17.
Select the "Settings" task, and then press keyboard 15.
A specific department code is set in the specific department memory 45 by operating . That is, after entering a specific department code using the number keys 31, the specific key 35 is input. Note that the specific department code is one of the department codes classified as products sold by weight (for example, department code 02).

Next, switch to the "registration" task. The cashier then operates the number key 31 and the person in charge key 34 to execute the sign-on process. That is, the user enters his or her own cashier Nα and presses the person-in-charge key 34.

Then, the sign-on flag F2 corresponding to the input cashier Nα in the cashier-specific memory 42 is set to 1''. In this state, if you operate the number key 31 and department key 32 to start registering sales items, the department Separate memory 4
1 and each sales area R1 of the cashier-specific memory 42,
The number of sold products and the sales amount are accumulated in R2. Furthermore, if the registered product belongs to a specific department code, the specific department sales area R3 of the cashier-specific memory 42 is updated.

Then, after the predetermined business hours have passed, the cashier again operates the number key 31 and the person in charge key 34 to execute the sign-off process. Then, the cashier's total sales data and sales data for a specific department will be, for example, the 10th
The receipt is printed and issued as shown in the figure. In addition, in FIG. 10, [Na001] is cashier Nα,
[Part 02] indicates a specific department code.

Incidentally, the sales amount of products sold by weight is determined using an electronic price scale. FIG. 8 is a block configuration diagram of a general electronic price scale, in which a CPU 51 that calculates the sales amount from weight data and unit prices is connected to a ROM 53 via a path line 52 and a unit weight of the weighed and sold product. A RAM 54 for storing the unit price per hit is connected. Additionally, a keyboard controller 56 inputs and converts key signals from the keyboard 55, an input port 58 inputs command signals from the mode switch 57, and a display unit 59 that drives and controls the display unit 59 for displaying weight, sales amount, etc. controller 6
0. A printer controller 62 that drives and controls a thermal printer 61 that prints the department code and sales amount of weighed sales products on receipts, and a load cell 6 installed in a weighing section 63.
A converting the analog signal from 4 into a digital signal
/D converter 65 connects the CP via the pass line 52.
Connected to U51.

Similarly to the RAM 14 in the electronic cash register, the RAM 54 of the electronic price scale in this embodiment includes a department memory 71 for accumulating sales points and sales amounts by department code for classifying metered sales products, Specific department memory 7゛2 for storing codes, cage ψ
It is assumed that a separate memory 73 for each cashier is formed for accumulating the number of sales items and sales amount of the products of the specific department code.

By doing this, when a weighed and sold product is placed on the weighing unit 63 and the product code of the product is entered using the keyboard, the sales amount is calculated from the weight data and the unit price of the product, and is printed on the receipt. At this time, the department to which the product belongs is determined and stored in the department memory 71.
is updated, and the relevant department is stored in the specific department memory 72.
If the department is within the department, the cashier-specific memory 73 is also updated.

Then, when issuing a report for the cashier-specific memory 73 is instructed in the "inspection" or "settlement" business mode,
For example, as shown in FIG. 11, the number of sales items and sales amount in a specific department for each cashier are printed and issued in sequence on a receipt. In addition, in FIG. 11, [N11oO1co,
[No. 002] indicates the cashier number, and [section 02] indicates the specific department code.

As described above, according to the electronic cash register of this embodiment, sales data of products belonging to a specific department code set in advance among the department codes for classifying products sold by weight can be aggregated for each cashier. The aggregated data is printed and issued on a receipt every time the cashier signs off. Therefore, by comparing the receipt issued for each cashier with the sales data report for a specific department code for each cashier issued from the electronic fee scale, it is easy to discover fraudulent entries by the cashier for products belonging to that department code. can. the result,
This naturally helps prevent unauthorized input.

In the above embodiment, one of the departments to which the strategically sold product belongs is set as the specific department, but a plurality of specific department codes may be provided by forming a plurality of specific department memories. Furthermore, it goes without saying that the department may be a department other than the department to which the metered sales product belongs. However, in this case, it is necessary to manage the sales of normally sold products by some method other than an electronic cash register. Further, in the embodiment described above, a case was shown in which the cashier's sales are printed and issued on a receipt in response to the cashier's sign-off process, but the receipt may also be issued as an inspection report or a settlement report.

[Effects of the Invention] As described in detail above, according to the present invention, it is possible to provide an electronic cash register that can aggregate sales data for a specific department code for each cashier and prevent unauthorized input by the cashier.
