Abstract

PURPOSE:To automatically specify and store the presence of an illicit act by providing plural open/close detectors, an illicit act number storage means, a correspondence discrimination means and an illicit act accumulation control means. CONSTITUTION:When money on deposit is inputted and stored as 10,000 yen, calculated change is 7,000 yen and the open/close detectors 31s-33s connected with paper money pressing devices 31p-33p mounted to paper money storage parts 31-33 for storing 1,000 yen bill, for instance, are opened and closed, a CPU as the correspondence discrimination means automatically discriminates the correspondence of the open/close operation and the inputted and stored money on deposit. In the case of noncoincidence here, the CPU as the illicit act accumulation control means is operated and the number of times stored in the illicit act number storage means RAM is updated and added. As a result, the presence of the illicit act can be estimated and discriminated by checking the number of times stored in the illicit act number storage means. Thus, appropriate measures such as giving warning to a casher and the change of the cashers, etc., can be adopted and the illicit act can be prevented beforehand.

Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an electronic cash register having a drawer.

[0002]

2. Description of the Related Art A drawer having a plurality of bill accommodating sections divided into banknote types and having bill holders attached to the respective drawers is provided, and a predetermined process such as change calculation is performed after inputting and storing the amount of a deposit from a customer. Electronic cash registers configured to perform are known.

As shown in FIG. 6, the drawer (30) has, for example, 10,000-yen bills, 5,000-yen bills, and bill accommodating portions 31, 32, and 33 for accommodating 1,000-yen bills, each of which can be opened and closed. The bill holders 31P, 32P, 33P are attached. In addition,
34 to 38 are coin accommodating portions.

When the cashier receives a deposit from a customer, the cashier inputs the amount by key operation and stores it in the RAM or the like. Then, predetermined processing such as change calculation is performed in relation to the sales amount. At this time, the received bills are stored in the bill storage unit corresponding to the amount of money before and after the key input operation of the deposit. That is, the bill retainer is opened, and after the bill is stored, it is closed by the spring bias. For example, if the deposit is a 10,000-yen bill, the bill retainer 31P is opened / closed and accommodated in the bill accommodation unit 31. Then, the calculated amount of change is given to the customer.

[0005]

By the way, the cashier includes not only the staff but also temporary workers such as part-time workers. Therefore, unfortunately some fraud can occur. That is 10,000 deposits
The yen is input and stored by a key operation and the difference of the sales amount of 1000 yen, that is, the change of 9000 yen is given to the customer, but the bill actually deposited by the customer is a 5000-yen bill.

[0006] However, such fraudulent behavior cannot occur unless the cashier and the customer are accomplices, and when a large number of electronic cash registers are operated, it is difficult to find out. In addition, it is quite difficult from a technical point of view to take measures to conclude that the act is fraudulent. However, it is also inefficient for managers to constantly monitor, and being alerted on the spot if they happen to discover it will cause a loss of credit and a decline in service.

The present invention has been made in view of the above circumstances, and an object thereof is to provide an electronic cash register having a function capable of automatically estimating and storing a fraudulent activity.

[0008]

An electronic cash register according to the present invention is provided with a drawer having a plurality of bill accommodating portions which are divided according to bill types and to which bill holders are attached, and which are used for depositing money from customers. In an electronic cash register formed to execute a predetermined process such as change calculation after inputting and storing an amount of money, the electronic cash register is arranged so as to be capable of detecting the opening / closing operation of each of the bill holders in relation to each of the bill holders. A plurality of opening / closing detectors, a fraudulent frequency storage means, and a means for discriminating whether or not the bill retainer whose opening / closing operation is detected before and after the input memory of the deposit corresponds to the memory deposit. And a fraudulent activity total control means for updating and adding the number of times of fraudulent activity stored in the fraud frequency storage means each time it is determined that there is no correspondence. That.

[0009]

In the present invention having the above structure, the deposit is 1000
When the change that is input and stored as 0 yen and calculated is 7,000 yen, for example, when the opening and closing detector involved with the bill holder attached to the bill accommodating section for accommodating the 1,000-yen bill is opened and closed,
The correspondence discriminating means inputs and stores the deposit (100
00) is automatically determined. In the case of this example, it does not correspond. Then, the fraudulent act total control means operates to update and add the number of times of fraudulent activity storage means.
Therefore, by checking the number of times of fraudulent activity stored in the fraudulent activity storage means later, it is possible to presume whether or not there has been an improper activity.

[0010]

Embodiments of the present invention will be described below with reference to the drawings. This electronic cash register has a plurality of (three) open / close detectors 31S, 3 in a general basic configuration as shown in FIG.
2S, 33S, fraudulent act count storage means 13M, correspondence discriminating means (11, 12), and fraudulent activity total control means (11,
12) is provided, and when the deposit money input and stored and the stored bills do not correspond, it is presumed that there is a fraudulent activity and the number of times of such fraudulent activity is cumulatively stored.

Further, in this embodiment, attention is paid to the journal image in which the day of the week, the time, etc. are stored, and the day of the week, the time, etc. at the time of the misconduct are stored in the misconduct frequency storage means 13M ( ST14 of FIG. 4).

First, as shown in FIG. 1, the basic structure of the electronic cash register is CPU 11, ROM 12, R.
AM 13, clock circuit 14, scanner 19 (scanner circuit 15), keyboard 20 (keyboard circuit 16), display 21 (display control circuit 17), input / output port (I / O)
A printer 22 (printer drive circuit 24) connected via 18 and a drawer 30 that is opened by a drawer opening device 25.

When the amount of banknotes (deposit money) received from the customer after the sales registration is entered by using the numeral keys or the like on the keyboard 20, the deposit money is stored in the RAM 13. In addition, change calculation is performed from the deposit and the sales amount. The data processed in this way is sent to the printer 22.
Will be printed on receipts and journals. For the data such as the day of the week and the time, the data stored in the RAM 13 as a journal image is read and printed. Since other functions are known, further description will be omitted.

As shown in FIG. 2, the drawer 30 has the same basic structure as that of the conventional example (FIG. 6), but a plurality (3) corresponding to the number (3) of the bill accommodating portions 31, 32, 33 is provided. 3)
The open / close detectors 31S, 32S, 33S are provided. The open / close detectors 31S, 32S, 33S are associated with the respective bill retainers 31P, 32P, 33P and detect the open / close operation thereof. In this embodiment, they are formed of limit switches as shown in FIG. It is connected through the port 18. However, as shown in FIG. 5, it may be directly connected to the import of the CPU 11.

That is, if the deposit is, for example, a 10,000-yen bill, the cashier opens the bill holder 31P as shown by the dotted line as shown in FIG. Return the bill holder 31P as shown by the solid line. Then, the open / close detector 31S operates. The open / close operation detection state is temporarily stored in the work area of the RAM 13 by the CPU 11.

Next, the correspondence discriminating means determines whether or not the deposited money input and stored by the key operation of the cashier corresponds to the bill holder (deposited money) whose opening / closing operation is detected as described above. The CPU11,
It is composed of the ROM 12 and is executed in ST12 of FIG. When the result of this determination is “not compatible”, it can be presumed in many cases that there was an illegal act by the cashier alone or by an accomplice with the customer.

Further, the fraudulent activity total control means 1 stores the number of fraudulent activity storage means 1 each time it is determined that the above "does not correspond".
A means for adding and updating to 3M, which is "1" in this embodiment, is composed of the CPU 11 and the ROM 12 and is ST of FIG.
It is executed in 13. In other words, it is a total of fraudulent acts. Further, the fraud frequency storage means 13M is the RAM 1
It is formed with three temporary storage areas. Therefore, the fraudulent activity total control means (11, 12) and the fraudulent activity count storage means 13M constitute a counter for counting the occurrence of fraudulent activity.

Further, in the case of this embodiment, the misconduct frequency storage means 13M stores the journal image such as the day of the week and the date and time at that time (ST14).

Next, the operation of this embodiment will be described. The sales amount is registered as 2500 yen and the cashier inputs the deposit as 10000 yen by the key operation and RAM13
Consider the case of being stored in. Then, the change (7500 yen) is calculated as a general function. This change is
It is displayed on the display 21 and printed on the receipt from the printer 22.

If the opening / closing detector 31S detects the opening / closing operation, the correspondence discriminating means (11, 12) discriminates "correspondence", so that it is presumed that there was no fraudulent activity.

However, when the open / close detector 32S detects the open / close operation and the detection result is stored in the RAM 13, C
The PU 11 performs the confirmation operation in ST10 of FIG. 4 and reads the detection result (ST11). Then, the correspondence determination means (1
1, 12) determines the correspondence between the deposit (10000 yen) and the bill retainer 31P for the 5000-yen bill that has been detected for the opening / closing operation. In this case, it is determined to be “not compatible” (ST1
2 NO).

Here, the illegal act total control means (11, 1)
In 2), "1" is added to the fraudulent frequency storage means 13M (ST13). That is, it is estimated that there has been a dishonest act, and the total is accumulated. At the same time, the CPU 11 stores the journal image such as the day of the week at that time (ST14).

According to this embodiment, however, the plurality of open / close detectors 31S, 32S, 33S, the fraud frequency storage means 13M, the correspondence discriminating means (11, 12), and the fraud accumulation control means (11, 12). ) And are provided, and the bill holder 31P, 3
2P and 33P opening / closing operations are detected, and the correspondence between the input / stored deposit and the stored bills, that is, the opening / closing operation of the bill holder is determined, and it is presumed that there was a misconduct in the case of "not corresponding". However, since it is configured to store the cumulative total, it is possible to automatically estimate and determine whether or not there has been a fraudulent act such as excessive change of money by looking at the storage result. Therefore, appropriate measures such as alerting the cashier and changing the cashier can be taken, which helps prevent such fraud.

Although it is presumed that there has been a fraudulent act, the fraudulent act count storage means 1 is the cumulative number of such acts.
It is only stored in 3M. In other words, the flicker display and buzzer do not sound each time, so if there is a mere mishandling, the well-meaning cashier will not be unnecessarily psychologically burdened and the customer will be uncomfortable. Don't worry.

Further, since the misconduct frequency storage means 13M is also configured to store the journal image such as the day of the week and the time when the estimated misconduct occurred, it is more objective and accurate to determine whether or not there has been a misconduct. Can be determined.

[0026]

According to the present invention, a plurality of open / close detectors, fraud count storage means, correspondence discriminating means and fraudulent activity cumulative control means are provided to detect the opening / closing operation of the bill holder and to detect the bill holder. The configuration is such that the correspondence with the deposits stored in the input memory is discriminated, and in the case of “not responding”, it is presumed that there was a fraudulent act, and the accumulated memory is stored. It is possible to automatically estimate and determine whether or not an action has been performed. Therefore, appropriate measures such as alerting the cashier and changing the cashier can be taken, which helps prevent such fraud.
