Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to an electronic cash register (hereinafter simply referred to as an ECR) in which only a predetermined operator can perform a registration operation.

) regarding. Regarding ECR, in order to obtain information about the cashier, a code is assigned to each cashier, and this cashier code is used to process information for each cashier.

However, in the conventional ECR using the cashier code, registration is possible by setting the mode key to registration mode, turning on the cashier key, and inputting the cashier code.

Once registration is possible, even if the mode key is turned off or the cashier key is turned off, registration can be performed again by turning on the registration mode key or the cashier key.

Therefore, if the cashier leaves his/her desk in the middle of the registration process and a third party other than the cashier operates the key intentionally or erroneously, there is a risk that the S will be registered incorrectly.

The purpose of this invention is to solve the problems of the conventional ECH described above and to prevent malfunctions caused by operations by others.
The goal is to obtain R.

In order to achieve the above object, this invention stores in advance an arbitrary code known only to the operator in a code storage means before starting registration, in addition to a predetermined operator code, and prevents registration. After the status has been set, when changing to a registration-enabled state, the code is input again, and the previously stored code is compared with the code entered this time. Only when they match can the ECR be registered again. It was designed to be in a state of

Hereinafter, the present invention will be described in detail along with embodiments shown in the drawings.

FIG. 1 is a block diagram showing the basic configuration of an ECR that implements the present invention.

In FIG. 1, 1 is a keyboard for inputting various input information, and 2 is a central processing unit (hereinafter referred to as CPU) that executes processes such as registration, inspection, and payment according to programs stored in ROM 3.

4 is a RAM as a storage unit. Furthermore, 5 is a display,
6 is a printer, and 7 is a cash drawer.

FIG. 2 shows the key arrangement on the panel of the keyboard 1 shown in FIG.

In FIG. 1, numerals 11 and 12 are cashier keys, which specify the cache storage area of the RAM 4.

13 is a mode key for switching and setting program mode P1 registration mode REG, inspection mode 16 is a cashier code key that indicates that the number input last time is a cashier code, 17 is a report key, and 18 is a registration key.

FIG. 3 is a diagram showing the arrangement of each storage area of the RAM 4 shown in FIG. 1.

In FIG. 3, 21 is a storage area specified by the cashier key 11, and 22 is a storage area specified by the cashier key 12.

The storage areas 21 and 22 have the same type of further subdivided storage sections.

Reference numeral 23 denotes a storage section provided for a flag indicating whether or not the storage area can be registered.

2'4 is a storage unit that stores the input code, 25 is a storage unit that stores the cashier code, 26 is a totalizer (TTL) that stores registration information, and 27 is a multiplier (CNT).
It is.

Next, in the ECH shown in Figure 1, enter the code from the keyboard 1.
The control operation of the CPU 2 when a cashier code etc. is input will be explained with reference to the operation flow shown in FIG.

Cashier key 1 to enable registration in Figure 1
1 is turned on.

As a result, the storage area 21 of the RAM 4 is used.

The cashier inputs a code (for example, a four-digit number) known only to him using the numeric keypad 14 of the keyboard 1.

By operating the numeric keypad 14, the operation flow shown in FIG. Memorized temporarily.

When the encryption key 15 is subsequently operated, the CPU 2 memorizes that the previously input numerical value is a code.

After the encryption key 15, a designated cashier code (for example, a two-digit number) is further input using the numeric keypad 14.

This numerical value is also temporarily stored in a register within the CPU 2 in the same manner as the code input.

Furthermore, when the cashier code key 16 is pressed subsequently, the operation flow is "Cashier key OFF? J NO→
``Key-in or JYES, then enter the code-cashier food, memorization and check routines from each key routine.

That is, in each key routine, when it is determined that the pressed key is the cashier code key (16D key), the operation flow enters "various checks".

In this step, for example, a key sequence check, a check of the number of digits of the encryption code/cache code, etc. are performed.

If the check is NO, error processing such as error display is performed.

If the check is OK, the process moves on to determining whether the cashier key is on.

Since the cashier key 11 has already been turned on, the next determination is made, but if the determination is made when the cashier key 11 is not pressed, the result will be NO and an error process will be performed.

Next to "Is the cashier key ON?", the process moves to the determination of "Is the memory cashier code = 0?"

Since the content of the cashier code storage unit 25 is "O" when the ECH registration operation starts on the day, the determination is YES.

If the determination is YES, the cryptographic code and the cashier code that have been entered manually and stored in the register of the CPU 2 are stored in the cryptographic storage section 24 and the cashier code storage section 25 of the storage area 21.

Then, a "1" flag is set in the registration permission storage section 23 of the storage area 21.

In other words, the state is set to "registration possible".

In this state, the cashier can input registration information.

On the other hand, if the registration operation is already in progress and the code and cashier code of the previously operated cashier are stored in the code storage unit 24 and cashier code storage unit 25 of the storage area 21, it is determined whether “cashier code = O”. is No, and in the next step, the content stored in the cipher storage unit 24 and the currently input cipher (stored in the register of the CPU 2) are processed.

). If the determination is YES, it indicates that the cashier who operated last time and the cashier who operated this time are the same person, and as a result of this determination, "1" is written in the registration permission storage unit 23 of the storage area 21 of the ECR. and becomes available for registration again.

When the registration becomes possible, the operation flow returns to the start.

When the registration is enabled, the cashier can switch the mode key 13 to the registration mode and start a normal registration operation.

Please note that mode key 1 is used to enter the code and cashier code.
There is no need to limit it to when 3 is set to registration mode,
Either mode may be used.

Further, if the determination of "cipher matching" is No, error processing is performed.

When the cashier performs the normal registration process, after inputting the amount information using the numeric keypad 14 and pressing the registration key 18, the operation flow is "Cashier key OFF? J NO →"
"Key in?" YES → "Registration key?" YES → "Various checks" OK → "Memory registration possible?" YES, and the registration operation is performed in the next step.

The above operation is repeated as long as the cashier continues the registration process at his or her desk.

When the cashier wants to leave his/her seat during work or temporarily stop work, the cashier key 11 is turned OFF.

When the cashier key 11 is turned off, the operation flow moves from the start to a determination of "cashier key OFF force", and since this determination is YES, next, the registration permission storage section 23 of the storage area 21 is set to "0", that is, registration is not possible. The state is set.

Since the determination of "key-in" is NO, the operation flow returns to the start again.

No matter how much registration information is entered in this state, the ECR will not be accepted.

When the cashier returns to his seat and starts registration again, he inputs the cashier key 11 into ONL and his own code and cashier code using the numeric keypad 14. The operation flow is as follows.
Is the cashier key OFF? J NO → “Key in? J Y
ES → “Various checks J OK → “Cash key ON”
YES → "Cashier code = O? J NO →"
If the code matches, it changes to YES and the registration permission storage unit 23 returns.
By setting "1" to , it becomes possible to register.

However, while the cashier is away, the three parties search for the cashier key, and even if the cashier key 11 is ONL, they do not know the cashier's code, so the cashier's code stored in the code storage unit 24 and the newly searched code It is almost impossible to find a match, and in the end, it is not possible to write "1" in the registration permission storage section 23, and it is not possible to set the ECR to the "6 registration possible" state.

Next, the operation when the cashier's registration work is completed and a settlement report is issued will be explained with reference to the operation flow shown in FIG.

When issuing a report, the cashier first sets the mode key 13 to payment mode, inputs a code using the numeric keypad 14, and then presses the code key 15 and report key 17.

As a result, the operation is started, and first, various checks are performed, and it is determined whether ``the cashier key is ON''.

Subsequently, the input code and the numerical value stored in the code storage unit 24 are compared.

If the comparison results do not match, an error will be handled, but
If they match, the report is then printed out.

When the hitting operation is completed, the cashier storage area 21 is completely cleared.

By clearing this storage area 21, it is natural that the registration permission storage unit 2
3 is also set to "O" and becomes unregistrable.

In the above embodiment, the setting to prohibit registration is made by turning off the cashier key, but this setting to prohibit registration may be performed by providing a special key separately.

In addition, in the description of the above embodiment, when the cashier key 11 is turned on, and the storage area 21 is described as the corresponding storage section, when the cashier key 12 is turned on.
The case where the data is registered in the storage area 22 can be considered in exactly the same way.

According to this invention, an arbitrary encryption code is input in addition to the operator code before registration starts and is stored in the ECR, and when the operator leaves the ECR, the ECR is set to a non-registration state and the registration is performed again. When starting registration, the user is required to enter an encryption code, and re-registration is possible only if the encryption code stored before registration matches the code entered this time, so a third party can Even if you try to process it, the ECR will not accept the registered data unless you re-enter the encryption code, and since this encryption code can be arbitrarily determined by the operator, it is impossible for a third party to know.
Therefore, malfunctions at the time of re-registration can be reliably prevented.
