Incidentally, in the "registration" mode, the sales data of the sales-registered product is registered in the storage unit, and the name, sales amount, etc. of the product are printed on the receipt paper and the journal paper by the printer 13 to issue the receipt. What is the "inspection" mode, which is a business mode? The printer 13 prints the total sales data of the sales products that have undergone the sales registration processing in the "registration" mode on the recording paper (the receipt and / or the recording paper). "Inspection" is the mode of business that outputs and issues an inspection report.
Similar to the mode, a business mode that clears the contents of the storage unit after printing out the total sales data of the sales products that have undergone sales registration processing on the storage unit and issuing a settlement report.
The “setting” mode is a mode of work in which data necessary for executing various modes such as “registration”, “inspection”, and “payment” is preset in the storage unit.

FIG. 3 is a block diagram showing the control circuit configuration of the POS terminal. The POS terminal has a CPU (central processing unit) 21 as a control unit main body. Further, a ROM (read / write) in which program data and the like are preset as a main storage controlled by the CPU 21.
And a RAM (random access memory) 23 in which a storage unit for registering product sales data and a work area for temporarily storing variable data are formed. .

The POS terminal also has a clock circuit 24 for measuring the current date and time, a communication interface 25 for transmitting and receiving data via a transmission path to and from a host computer which is a higher model of the POS terminal. A drawer opening device 15a for opening the drawer 15 while receiving a signal from the mode switch 16

The CPU 21, the ROM 22,
RAM 23, clock circuit 24, host interface 2
5, the I / O port 26 and the controllers 27 to 30 are electrically connected by a bus line 31.

FIG. 4 is a view showing a main memory area formed in the RAM 23, 41 is a memory for each transaction,
42 is an input amount limit table. Memory by transaction 4
Reference numeral 1 is a table for accumulating the amount and points of products registered at the POS terminal for each transaction, and the transaction items are "total sales", "net sales", "discount", and "cancel". Etc. In addition, each item of the withdrawal work "cash purchase",
There is also provided an area 41a for accumulating the input amount and the number of inputs (points) corresponding to "electricity charge", "water charge", "other expenses" and the like.

In the input amount limit table 42, the input amount limit is set in advance for each item (“cash purchase”, “electricity charge”, “water charge”, “other expenses”, etc.) of the withdrawal work. It is a set table and constitutes limit amount storage means. Here, the limit amount is the upper limit amount of the input amount registered in one withdrawal operation.

Therefore, when the "registration" mode is selected by the mode switch 16 and the withdrawal key K9 is operated and the withdrawal operation is selected, the CPU 21 selects
It is program-controlled to execute the processing shown in the flowchart of FIG.

That is, after confirming that the "registration" mode is selected as ST (step) 1, ST2
As a result, on the operator screen 12a of the display device 12, a withdrawal task selection screen in which a unique selection number is attached to each withdrawal task item is displayed.

In this state, when one of the selection numbers on the screen is input by the numeric key K1 in ST3, the withdrawal operation of the item with the input selection number is selected, and therefore, in ST4. Wait for input of the withdrawal amount in the corresponding withdrawal business.

Here, when the amount data is entered with the numeric key K1 and the amount key K8, the input amount limit corresponding to the withdrawal operation selected from the input amount limit table 42 is read out in ST5, In ST6, the input amount limit is compared with the input amount data (amount comparing means).

As a result of this comparison, if it is confirmed that the input amount data is less than or equal to the input amount limit,
The amount data input as ST7 is added to the total amount area corresponding to the corresponding withdrawal operation item of the transaction memory 41 as the withdrawal amount of the selected withdrawal operation (withdrawal amount registration means). Also, the number of inputs = 1 is added to the total score area corresponding to the withdrawal work item. Then, this process ends.

On the other hand, when it is confirmed that the input amount data exceeds the input amount limit amount as a result of the comparison in ST6, for example, a message notifying that the input amount is an error is displayed on the display screen 12a. (Error notifying means), and this processing is ended.

In this embodiment having such a configuration, the input amount limit amount is set in advance in the input amount limit amount table 42 for each item of various withdrawal tasks in the "setting" task. For example, with respect to the withdrawal business “cash purchase”, the record maximum amount of goods purchased in cash or an amount slightly higher than that is set as the input amount limit. Similarly, with respect to the withdrawal operation “electricity fee”, the highest monthly amount of electricity bill or a slightly higher amount is set as the input amount limit amount.

When a dispensing operation occurs, the operator (store manager, clerk, etc.) operates the dispensing key K9 in the "registration" mode. Then, the withdrawal task selection screen is displayed on the display screen 12a for the operator, and the selection number of the corresponding withdrawal task is entered and selected.

For example, if the payment of the electricity charge occurs and the selection number corresponding to the withdrawal operation "electricity charge" is "2",
Input the number data "2" with the number key K1. Then, the withdrawal operation "electricity charge" is selected.

Next, the operator inputs the payment amount of the electricity charge by using the numeral keys K1 and the money key K8. Then, this input amount of money is compared with the input amount of money limit corresponding to the withdrawal operation "electricity charge" set in the input amount of money limit table 42, and if the input amount of money is less than or equal to the limit value, the input amount of money is withdrawn. It is registered in the transaction memory 41 as the withdrawal amount of the business "electricity fee".

On the other hand, when the input amount exceeds the limit, a message notifying that the input amount is an error is displayed on the display screen 12a and the registration process is not performed.

Therefore, in the withdrawal operation, when the amount data exceeding the input amount limit set in the input amount limit table 42 is input, an error is notified and the withdrawal operation registration process is prohibited. , It is possible to prevent the input of fraudulent amount data that exceeds the input amount limit. As a result, it is possible to suppress damage caused by fraudulent activities such as cheating on cash in the drawer and cheating as cash out.

By the way, in the first embodiment, the input amount limit amount for one withdrawal operation is fixedly set, and the input amount and the limit amount are compared every time the withdrawal amount is input. Therefore, it is possible to prevent illegal registration of the amount exceeding the limit as the withdrawal amount at one time. However, even if the amount less than the limit amount is divided into multiple times and is illegally registered as the withdrawal amount, and the cumulative amount of the withdrawal amount eventually exceeds the limit amount, it cannot be detected.

Therefore, a second embodiment capable of preventing the latter fraud will be described next. The second embodiment is applied to a POS terminal as in the first embodiment, and the appearance, the keyboard, the control circuit configuration, and the RAM area configuration are the same, so that FIGS. The description will be omitted.

In the second embodiment, the CPU
When the "registration" mode is selected by the mode switch 16 and the withdrawal key K9 is operated and the withdrawal operation is selected, 21 is program-controlled so as to execute the processing shown in the flowchart of FIG. Has been done.

That is, after confirming that the mode is the "registration" mode as ST1, a withdrawal task selection screen is displayed on the operator screen 12a as ST2. In this state, S
When one of the selection numbers is entered as T3 and one of the withdrawal operations is selected, and then withdrawal amount in the selected withdrawal operation is entered as ST4, the input amount limit table is entered as ST5. The input amount limit amount corresponding to the withdrawal operation selected from 42 is read out, and this input amount limit amount is compared with the input amount data in ST6 (amount comparing means).

Then, as a result of this comparison, if it is confirmed that the input amount data is less than or equal to the input amount limit,
The amount data input as ST7 is added to the total amount area corresponding to the corresponding withdrawal operation item of the transaction memory 41 as the withdrawal amount of the selected withdrawal operation (withdrawal amount registration means). Also, the number of inputs = 1 is added to the total score area corresponding to the withdrawal work item. In addition, this ST1
The processing from ST7 to ST7 is the same as in the first embodiment.

Thereafter, in ST8, the input amount data is subtracted from the input amount limit corresponding to the selected withdrawal operation in the input amount limit table 42, and the input amount limit is updated. Then, if updated, this process is terminated.

In the second embodiment having such a configuration, every time a withdrawal amount equal to or less than the limit amount set in the input amount limit table 42 is registered in the withdrawing operation, the withdrawal amount is changed from the limit amount. Is subtracted and the limit is updated. And if there is a withdrawal amount exceeding the limit,
An error is notified and the withdrawal business registration process is prohibited.

Therefore, when the amount less than or equal to the limit amount is divided into multiple times and is illegally registered as the withdrawal amount, an error is notified when the accumulated amount of withdrawal amounts eventually exceeds the limit amount. Therefore, this type of fraud can be discovered. As a result, it is possible to suppress damage caused by fraudulent activities such as cheating on cash in the drawer and cheating as cash out.

By the way, in the second embodiment,
It is necessary to restore the limit amount in the input amount limit table 42 to the initial value at an appropriate time. Therefore, for example, in the setting work before the opening of the store on the first day of every month, it may be arranged to restore the limit amount in the input amount limit table 42 to the initial value by the manual operation.

Further, as shown in FIG. 7, a limit amount initial value area 42a is provided in the input amount limit amount table 42, and the limit amount initial value is fixed in advance in this area 42a depending on the type of withdrawal work. Then, in the settlement operation performed after the store is closed every day, on the last day of the month, the input amount limit amount of the type in the input amount limit table 42 is automatically restored to the corresponding limit amount initial value. It is also possible.

That is, as shown in FIG. 8, the CPU 21 executes the ordinary settlement operation processing in the settlement operation and, when completed, reads the date data counted by the clock circuit 24. Then, if the date is not the last day of the month, this settlement operation is ended.

On the other hand, when the date is the last day of the month, the data is restored by copying the corresponding data in the initial amount limit area 42a to the input amount limit area of the input amount limit table 42. . Then, this settlement work is completed.

By adopting such a configuration, it is possible to omit the work of restoring the input amount limit amount of the input amount limit table 42 to the limit amount initial value, prevent forgetting to restore, and simplify the operation. Therefore, the operability can be improved.

In each of the above-mentioned embodiments, the case of displaying and outputting the message for notifying the error as the error notifying means has been shown, but the error may be notified by means such as generation of a buzzer sound or blinking of the LED. Good. Further, the error notification message may be transmitted to the host computer via the communication interface 25 so that the operator of the host computer is also notified of the error. By doing so, the effect of suppressing fraud can be further enhanced.

In addition to the above, the present invention can be applied to a single electronic cash register and various modifications can be made without departing from the scope of the present invention.

[0048]

As described above in detail, according to the present invention, when the amount data inputted in the withdrawal work is less than the limit amount stored by the limit amount storing means, the input amount is stored in the storage unit as the withdrawal amount. Registration is processed, but if the limit is exceeded, an error is notified and registration is prohibited.

Therefore, it is possible to provide an electronic cash register capable of suppressing damages caused by fraudulent activities such as disposing of cash in a drawer and cheating as a withdrawal.
