Abstract

PURPOSE:To prevent dishonesty in cash delivery by permitting the execution of the adjustment and the setting work when a personal identification number set beforehand and the inputted number are coincident. CONSTITUTION:When the adjustment and setting work with a high importance are selected by a control key, the adjustment and setting routine are executed and a personal identification number is inputted from a keyboard 12. After it is confirmed that the inputted number is coincident with the number of digits of the personal identification number, this is stored into an input personal identi fication number memory 63 as an input personal identification number. Next, a collating means 4 compares and collates the set personal identification number in a set personal identification number memory 62 and the above-mentioned input personal identification number and only when the numbers are coincident, the execution of the adjustment and setting work is permitted by a control means 15.

Description

[Detailed description of the invention] [Industrial application field] The present invention relates to electronic cash registers.

[Prior Art] Generally, electronic cash registers have a built-in central processing unit (C
A control key operated with a key is provided as a control switch for issuing commands to the PU. here,
"Registration" is the process of storing the sales amount, number of items sold, etc. of sold products in the storage unit, calculating the total amount, and printing the results on receipts and journals.

"Inspection" is a job that prints out the total sales amount, total sales points, etc. compiled in the storage unit by "registration" on recording paper. "Settlement" is a task in which, for example, at the end of ten business hours, the total sales amount, total sales points, etc. compiled in the storage section are printed out on recording paper, and the contents of the storage section are cleared.

"Settings" refers to the settings for "registration" prior to the start of "registration".
This is the task of setting the information necessary to perform "inspection", "settlement", etc. in the storage unit.

"Registration" and "inspection" tasks can be carried out not only by managers such as store managers, but also by people in charge of operating electronic cash registers called cashiers.
``Settlement'' and ``Settings'' tasks can only be performed by the administrator, as there is a risk of data theft or other unauthorized use. For this reason, there are two types of keys to operate the control keys, of which the key that allows selection of all business modes is held by the person in charge of management, and the key that does not allow selection of "Payment" and "Setting" jobs is held by the person in charge of operation. are doing.

[Problems to be Solved by the Invention] However, in conventional electronic cash registers of this type, it is possible to execute a selected task only by the key position of the control key, so it is possible for the key for the manager to be stolen or for the person responsible for the operation to be carried out. By tampering with keys intended for individuals, even someone other than the person in charge of management could easily perform ``accounting'' or ``setting'' tasks, making it impossible to reliably prevent fraud.

Therefore, the present invention aims to provide an electronic cash register that prevents anyone other than a specific person from performing "accounting" and "setting" tasks, and that can reliably prevent fraud such as data theft.

[Means for Solving the Problems] As shown in FIG. 1, the electronic cash register of the present invention includes a set password memory 11 for storing a preset password, and a keyboard 12 for storing a password set in advance. The input password memory 13 stores manually inputted number data as a password, and the input password stored in the input password memory 13 is compared with the setting password stored in the setting password memory 11. The system is equipped with a password verification means 14 and a control means 15 for permitting execution of inspection work or settlement work when the verification means 14 matches both passwords.

[Function] If the electronic cash register is equipped with such a method, the keyboard 12 can be used for setting or payment processing.
When a password is input from the input password, this input password is stored in the input password memory 13. Then, the input password stored in the input password memory 13 and the set password stored in the set password memory 11 are compared and verified by the password verification means 14, and control is performed only when both passwords match. Means 15 permits execution of inspection work or settlement work. Therefore, even if a "setting" or "accounting" task is selected by operating the key position of the control key, the task cannot be executed unless the user knows the password.

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

and a control key 23 are provided, and the sales amount of the sold product is displayed on the upper front part.

A display 24 is provided for displaying the total amount and the like. Further, a printer 25 for printing on receipts and journals is provided adjacent to the display 24, and a receipt issuing port 26 is formed below the printer 25. Furthermore, a drawer 27 for storing cash and the like is installed on the lower surface of the housing 21.

On the keyboard 22, as shown in FIG.
Product code key 31 for inputting the product code set in , and the sales amount of the sold product.

A number key 32 for entering the number of sales items, etc., a multiplication key 33 for instructing that the number data is the number of sales items, a subtotal key 34 for displaying the subtotal on the display 24 and printing it on the receipt and journal. In addition to sales registration keys such as a deposit/total key 35 for commanding the closing of registration by cash settlement transactions, various function keys such as a clear key 36 and a cancel key 37 are provided.

The control key 23 is rOFFJ as shown in FIG.
- "Registration" - "Inspection" - "Payment" - "Setting" can be operated using a key in this order, and commands the CPU to execute the business mode corresponding to the key position. and,
The key is that it can be rotated from rOFFJ to "Settings" and r
A key for the administrator that can be extracted at the OFFJ and "registration" positions, and a key that can be rotated from rOFFJ to "inspection" and
There is a key for each person in charge of operation that can be extracted at the OFFJ and "registration" positions.

FIG. 5 is a block diagram showing the circuit configuration of the electronic cash register. The CPU 51 has a built-in arithmetic circuit, a memory control circuit, etc., and performs predetermined arithmetic processing based on key manual data from the keyboard 22, and also stores programs etc. for executing the above-mentioned tasks via the pass line 52. ROM 53 for storing key information, and RAM 5 for storing key-generated sales data, etc.
4. Also, a keyboard controller 55 inputs key signals from the keyboard 22 and converts them into signals that can be processed by the CPU 51, a display controller 56 drives and controls the display 24, and controls the printer 25 and opens and closes the drawer 27. A printer/drawer controller 57 that inputs a key position signal from the control key 23, an input port 58 that inputs a key position signal from the control key 23, a buzzer circuit 59 that sounds a buzzer, etc. are connected to the CPU via the path line 52.
51.

As shown in FIG. 6, the RAM 54 stores sales data such as the total sales amount and total sales points based on the sales data of sales products inputted from the keyboard 22 by product code, transaction, and operation manager. A sales tally file 61 for counting data, a set password memory 62 for storing preset passwords, a manual password memory 63 for storing passwords entered manually from the keyboard 22, and the like are formed.

The CPU 51 is configured to determine the key position of the control key 23 when there is a key input from the keyboard 22, and to execute program processing according to the key position. If the key position of the control key 23 is "registration", a normal registration routine is executed. In other words, the sales summary file 6 is created based on the product code, number of sales items, sales amount, etc.
Update the sales data of 1. Also, the number of items sold.

The sales amount, etc. are printed out on the receipt and journal, and are also displayed on the display 24. In this state, when the subtotal key 34 is input, the subtotal amount is printed out on the receipt and journal and displayed on the display 24. When the deposit/total key 35 is input, change is calculated, a receipt is issued, and the drawer 27 is opened.

When the key position of the control key 23 is "inspection", a normal inspection routine is executed.

That is, the sales data compiled in the sales summary file 61 is read out in sequence based on key human power, printed out on a receipt by the printer 25, and issued as an inspection report.

On the other hand, if the key position of the control key 23 is "Payment", the payment routine shown in FIG. 7 is executed.

That is, after confirming that the manual input key is the numeric key 32 and that the numeric data matches the number of digits of the PIN, this digit data is input as the manual PIN in the PIN memory 63.
Store in. Next, the set password in the set password memory 62 is compared with the input password in the input password memory 63 to determine whether or not the two passwords match. If they match, normal payment processing is executed. That is, the sales data compiled in the sales summary file 61 is read out in sequence based on key human power, printed out on a receipt by the printer 25 and issued as a settlement report, and the contents of the sales summary file 61 are cleared. On the other hand, if the two passwords do not match, the key input is canceled as a mismatch process, and the buzzer circuit 59 is driven to sound a buzzer.

When the key position of the control key 23 is set to "setting", a setting routine similar to that for "checkout" shown in FIG. 7 is executed. That is, after confirming that the input key is the numeric key 32 and that the numeric data matches the number of digits of the password, the numeric data is stored in the input password memory 63 as the input password. Next, the setting password in the setting password memory 62 and the input password memory 6 are stored.
A comparison is made with the manual PIN number in 3 to determine whether the two PIN numbers match. If they match, normal setting processing is executed. On the other hand, if the two passwords do not match, the manual key input is canceled as a mismatch process, and the buzzer circuit 59 is driven to sound a buzzer.

In the electronic cash register of this embodiment configured as described above, when executing payment processing or setting tasks, the manager operates the control key 23 with the manager's key that he or she owns, and adjusts the key position. to "Payment" or "Settings".

Then, the user operates the number keys 32 on the keyboard 22 to input a preset password. Then, the manually entered password is compared with the password set in advance in the set password memory 62 of the RAM 54,
If both passwords match, execution of normal payment operations or setting operations is permitted. On the other hand, if the two passwords do not match, the payment transaction or the execution of the payment transaction will not be permitted.

Therefore, according to this embodiment, even if the key position of the control key 23 is set to "Payment" or "Setting", if the preset password is not entered accurately from the keyboard 22, the setting work and the payment work are executed. I can't. In other words, only the person in charge of management who knows the PIN number can perform the settlement work and setting work.

Therefore, even if the control key 23 is set to "Payment" or "Settings" by stealing the key for the administrator or tampering with the key for the operation manager, the setting work cannot be performed unless the specified PIN is entered. Since the payment transaction cannot be executed, it is possible to reliably prevent theft of important data necessary for the payment transaction or setting transaction, and this has the effect of preventing fraud before it occurs. In addition, since the numeric key 32 on the keyboard 22 is used as a means for inputting the password,
A high-performance electronic cash register can be obtained at low cost without requiring a special input device such as a keypad for manually inputting a password.

In addition, in the above embodiment, the set password is stored in the RAM 54.
Although the case where the information is stored in the ROM 53 is shown, it goes without saying that the information may be stored in the ROM 53.

[Effects of the Invention] As described in detail above, according to the present invention, only a specific person can perform "accounting" and "setting" tasks, and an electronic system that can reliably prevent fraud such as data theft is provided. We can provide cash registers.
