Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a self-scanning system device that allows a customer to scan the product data of a purchased product.

[0002]

2. Description of the Related Art For example, in a checkout device provided in a supermarket, a customer himself / herself uses a self-scanning system device to scan the product data of a purchased product, and a checkout operation including money transfer is performed electronically. There is a cash register that is configured to be performed by a clerk (cashier).

For example, the checkout device disclosed in Japanese Patent Laid-Open No. 61-46591 is a dual-purpose cashier system comprising a plurality of self-scanning system devices and a common electronic cash register. On the other hand, 1
There is also a dedicated system including one or two self-scanning system devices and one or two dedicated electronic cash registers.

FIG. 6 shows a general structure of the latter checkout device. In the figure, reference numeral 1 is a self-scanning system device, which is an operation unit 10 for a customer to perform a scanning operation, a loading / weighing unit 20, an unloading unit 40, and a stock / bagging unit 50.
And are arranged in rows in the product flow direction. The operation unit 10 includes
A product reading means (optical scanner or the like) 11 for reading a bar code attached to a product and an input / display unit 12 including various switches such as a start button and a display are provided. Further, the carry-in / measurement unit 20 is a carry-in conveyor 2 for carrying in the self-scanned products in the arrow direction.
1 and a weighing machine 22 that weighs the weight of the product placed on the carry-in conveyor 21. Carry-out section 40
Includes a carry-out conveyor 41 and an inclined shooter 42, and is configured to carry out the products after settlement to a stock / bagging unit 50 having a stock place 51.

Here, the electronic cash register 31 is
It forms the settlement unit 30, and is provided between the carry-in / measurement unit 20 and the carry-out unit 40.

In such a checkout device, when the customer himself scans his or her purchased merchandise on the operation unit 10, the merchandise data is stored in the electronic cash register 31.
While being registered in the sales registration file of, the products are conveyed to the stock / bagging unit 50 through the carry-in conveyor 21 and the carry-out conveyor 41.

Therefore, the cashier is the settlement unit 30.
In the above, it is only necessary to perform the settlement work for the customer after scanning. After that, the customer will be bagged at the stock location 51. Therefore, the cashier can concentrate on the settlement work only, which improves the work efficiency. On the other hand, customers can shop quickly without waiting for a long line. According to the checkout device disclosed in the above publication, work efficiency can be further enhanced by the dual role of cashier.

However, regardless of the dual-use system or the exclusive-use system, in such a self-scanning system device 1, the product scanned by the customer and the carry-in conveyor 21 are used.
There may be a case where the product actually placed on the customer does not match. If this is left unattended, the settlement work becomes troublesome and the improvement of work efficiency and customer service due to the introduction of the self-scanning system device 1 cannot be achieved. On the other hand, when a customer is willing to do so, it is difficult to overlook this dishonesty.

Thus, in such a checkout device, a weight comparison / determination means is provided, and the weight (Wd) of the product scanned by the customer is read from the product data file in the electronic cash register 31 and placed on the carry-in conveyor 21. The weight (Wm) of the product is automatically measured by the measuring device 22, and it is automatically determined whether or not the weights of the two match.

That is, when the customer places the scanned article on the carry-in conveyor 21, as shown in FIG.
The weighing device 22 automatically weighs the weight Wm of the product (ST
30) On the other hand, the control unit such as the electronic cash register 31 reads the data input by scanning (ST).
31), it is determined that the input data is a regular product registered in the product data file (YES in ST32), and both weights match (Wm = Wd) by the weight comparison / determination means (YES in ST33). Under this condition, the carry-in conveyor 21 is driven (ST34) and the sales are registered (ST35). Then, a message notifying the customer of the next procedure is displayed and output on the display unit (12) (ST37).

On the other hand, when the merchandise weight is not a legitimate merchandise item (NO in ST32) or the scanning input merchandise weight Wd does not match the automatically weighed merchandise weight Wm (N in ST33).
In O), as the applicant has previously proposed, an alarm is issued only once, and a message such as "Please rescan" or "Place the scanned product" is given to the customer. Display (ST36). Further, in this case, the conveyor 21 is kept stopped. Therefore, it is possible to improve business efficiency and service while preventing intentional or negligent fraud.

[0012]

However, the following problems have been pointed out in the above-described conventional self-scanning system device 1 as the spread thereof spreads.

That is, when a product different from the scanned product is placed on the carry-in conveyor 21 in addition to the scanning mistake, an alarm is issued only once and a coping message is displayed. There is a person who does not notice this alarm / action message. Especially for beginners, even experienced people may not notice it when the store is busy. Even if the user notices the alarm / coping message, if the alarm / message disappears while the user is confused, it may not be possible to take appropriate measures. Further, even if the alarm / handling message is noticed, some customers do not think it is their own mistake, and think that it is a signal to start the conveyance drive of the conveyer 21, for example, and do not care about the signal on the device side.

However, it is virtually difficult for the cashier to leave the settlement section 30 and go to the operation section 10 each time. In particular, it is impossible to leave the place itself by the dual-purpose system of the cashier. Therefore, the wrong product remains on the carry-in conveyor 21,
Since it cannot proceed to the next step, it hinders self-scanning and settlement operations after that, resulting in a decrease in sales efficiency and a long line, resulting in poor customer service.

It is an object of the present invention to provide a self-scanning system device having a reminder function capable of promptly removing an incorrect product when it is placed on a conveyor. It is in.

[0016]

According to the present invention, even if an alarm or a coping message is continuously issued, the alerting power to the customer is likely to decrease with time, and if the coping message is changed, the customer is also easily satisfied. In many cases, attention should be paid to the fact that the alarm volume cannot be increased more than necessary, but if it is increased in some cases, the alerting power can be significantly increased, and the customer must remove the product from the conveyor. The configuration is such that the second coping message is repeatedly displayed again to achieve the above object.

That is, the self-scanning system device according to the present invention includes an operation unit including product reading means arranged in a row in the product flow direction, a carry-in conveyor, a carry-in / measurement unit having a measuring device, and a carry-out conveyor. It consists of a carry-out section and a stock / bagging section with a stock location, and the product weight corresponds to the product data of the product that the customer self-scanned in the operation section and the customer puts it on the carry-in conveyor and weighs it with a weighing machine. In the self-scanning system apparatus provided with the weight comparison and determination means for comparing and determining the measured weight of the product, the weight comparison and determination means determines that the product weight and the measured weight do not match. A countermeasure message display means for displaying and outputting the first countermeasure message to the customer, and a display output operation of the countermeasure message display means After that, the re-weighing control means for re-weighing the weighing instrument and the second re-handling message for re-displaying and outputting the second re-handling message for reminding the customer further if the re-weighing weight is not zero are displayed again. Display means,
Is provided.

[0018]

In the present invention having the above-described structure, the weight comparison / determination means compares the product weight data corresponding to the scanning product data with the measured product weight data to determine whether the two weights are equal.

When it is determined that the two weights do not match,
The coping message display means displays a first coping message to the customer, for example, "please place the scanned product on the conveyor." Therefore, the customer can promptly remove the mistaken product placed by mistake from the conveyor. This can be confirmed by the fact that the re-weighing weight from the weighing instrument which the re-weighing control means has performed the re-weighing operation is zero.

However, if the re-weighed weight is not zero, the countermeasure message re-display means operates and re-displays the second countermeasure message, for example, "Remove the commodity on the conveyor and place the scanned commodity." Hereinafter, this redisplay is repeated, for example, at regular intervals. Therefore, it is possible to further call the customer's attention, and it is possible to quickly eliminate the inconvenience of leaving the mistaken product on the conveyor.

[0021]

Embodiments of the present invention will be described below with reference to the drawings. As shown in FIG. 3, this self-scanning system device has two units (1A, 1B) arranged in parallel, and a common settlement unit 30 [two electronic cash registers 31 in the middle.
(A), 31 (B)] is provided as a so-called two-lane checkout device.

This self-scanning system device 1A
The basic configuration of (1B) is similar to that of the conventional example (FIG. 6), but the countermeasure message display means (31A, 31B,
14), remeasurement control means (31A, 31B), and handling message redisplay means (31A, 31B, 14),
When the customer determines that the self-scanned product (weight Wd) and the measured product (weight Wm) do not match, the first countermeasure message for instructing to remove the erroneous product placed on the carry-in conveyor 21 is displayed. The second coping message is displayed and then repeatedly displayed again for further attention. Further, in this example,
The buzzer 17 is sounded and an alarm is issued when the first countermeasure message is displayed and the second countermeasure message is displayed again.

The same or common parts as those of the conventional example (FIG. 6) are designated by the same reference numerals, and the description thereof will be simplified or omitted.

In FIG. 3, the scale 22 has a structure for automatically weighing the weight of the product placed on the carry-in conveyor 21 which is stopped. Therefore, since it can be arranged corresponding to the upstream side of the carry-in conveyor 21, it is much smaller and more accurate than the conventional example. In addition, the carry-in conveyor 2 in operation
Since it does not come into sliding contact with 1, it can be constructed at a low cost with a simple structure. Further, since the weighing device 22 can be configured to be able to move up and down, after the weighing, that is, the carry-in conveyor 21
During operation of the
Can be separated from.

The shelves 15 in FIG. 3 are used to temporarily store products or the like that have failed in self-scanning.

By the way, the handling message display means, the re-weighing control means, and the handling message re-display means in this embodiment are the components of the electronic cash register 31 (A) [31 (B)] constituting the settlement unit 30 and the components thereof. It is built by combining the functions of. Therefore, first, the electronic cash register 31 will be described.

In FIG. 1, the electronic cash register 3
Reference numeral 1 denotes a CPU 31A that manages calculations, judgments, commands, etc., a ROM 31B that stores various programs and fixed data, a RAM 31C that temporarily stores various data, a keyboard 32 (controller 32C), a printer 37 (controller 37).
C), drawer 34 (controller 34C), operator display 35 (controller 35C), customer display 3
6 (controller 36C), an interface 31D, etc., it is possible to perform data processing in a general setting mode, registration mode, inspection mode, and settlement mode, and is capable of data transmission with a host computer (not shown).

The RAM 31C has a work area WA and a sales registration area RM for temporarily storing data being processed.
There is a product data file area DA. In the product data file area DA, as shown in FIG. 2, the product code, the product name, the unit price, and the weight Wd of the product are preset and stored. In the sales registration area RM, in addition to the product data self-scanned by the customer on the operation unit 10, the scanner 33 (controller 33C) shown in FIG.
Alternatively, the product data input by the cashier operating the keyboard 32 is also stored.

On the other hand, the interface 31D is connected to the following devices constituting the self-scanning system device 1.

That is, the commodity reading means 11 forming the operation unit 10, the four-stage display 14, the start switch 15,
Input with stop switch 16 and buzzer 17
The display unit 12 is connected. The start switch 15 is for declaring that the customer starts inputting, that is, scanning of product data for self-purchase using the product reading means 11, and the stop switch 16 is for declaring its end.
Therefore, when the start switch 15 is turned on, the self-scanned product data is transferred to the interface 31.
It is automatically input to the electronic cash register 31 via D, and the scanned product data is temporarily stored in the working area WA of the RAM 31C.

On the other hand, the weighing device 22 is means for automatically weighing the weight Wm of the self-scanned product placed on the carry-in conveyor 21 in which the customer is stopped.
It is temporarily stored in the working area WA of C.

Further, the conveyor controller 29 connected to the interface 31D is means for controlling the operation of the carry-in conveyor 21 and the carry-out conveyor 41. The operation of the carry-in conveyor 21 is started by the conveyor operation control means described later, and the sensor 23 provided on the downstream side of the carry-in conveyor 21.
This conveyor controller 29 stops when (FIGS. 1 and 3) detect a product. On the other hand, the carry-out conveyor 41 is transported after the start switch 15 is turned on. Also, this conveyor controller 29
1, as shown in FIG. 1, the foot switch 38 provided in a range where the cashier can be operated makes it possible to carry the carry-in conveyor 21 and to operate the emergency switch 3.
It is possible to make an emergency stop at 9.

The product reading means 11, the input / display unit 12, the weighing device 22, and the conveyor controller 29 are
Based on the program shown in FIG. 4 stored in the ROM 31B, the drive control is performed in association with the control of the CPU 31A.

The weight comparison / determination means compares the product weight data (Wd) with the measured weight data (Wm) and determines whether or not both weights are equal (Wm = Wd).
In this embodiment, it is composed of a CPU 31A and a ROM 31B. Specifically, it is executed in ST13 of FIG.

The product weight data (Wd) is stored in the product data file (DA) shown in FIG. 2 on the basis of the scanning product data (D) input by the customer's self-scanning and temporarily stored in the RAM 31C. The weight of the product in question is calculated by the CPU 31A.

Next, the conveyor operation control means is the CPU 3
1A, ROM 31B, and the weight comparison and determination means (31A, 31B) determines that both weights are equal (Wm = Wd) (YES in ST13), and convey operation of the carry-in conveyor 21 to the conveyor controller 29. It outputs a command signal. That is, only when the customer self-scans the self-purchased product and places the product on the carry-in conveyor 21, the carry-in conveyor 21 is started and the carrying operation is started (ST13, 14 in FIG. 4).
Therefore, the wasteful operation of the carry-in conveyor 21 is eliminated,
There is no need to reverse the carry-in conveyor 21. Moreover, since only the regular purchased products are conveyed, it is possible to operate at high speed.

Here, when the customer places a commodity different from the self-scanned commodity on the conveyor 21, the coping message display means means that the weight comparison and determination means (31A, 31B) do not match the weights (Wm ≠). W
The CPU 31A, RO shown in FIG. 1 is a means for displaying and outputting the first countermeasure message on condition that it is determined as d).
It is composed of M31B and the display 14 in the input / display unit 12, and is executed in ST13 and ST16 of FIG. First
The handling message of is, for example, "Please replace the product on the conveyor with the scanned product." ROM3
It is stored in 1B.

In this embodiment, when the first countermeasure message is displayed and output (ST16), the CPU 31
The A and ROM 31B are formed so as to sound the buzzer 17 and issue an alarm (ST16). Furthermore, CP
The U31A and the ROM 31B are supposed to display a warning message and alarm even if the self-scanning is unsuccessful (ST12) and the product is placed on the carry-in conveyor 21 without self-scanning (ST1).
6). Therefore, this is to prevent the customer's negligence and intentional fraud.

Next, the re-measurement control means and the handling message re-display means for expressing the alert function are the CPU 31A,
It is composed of the ROM 31B, the display unit 14 and the like, and the ST of FIG.
It is executed at 20-23.

This reweighing control means (CPU 31A, RO
M31B) is the countermeasure message display means (31A,
31B, 14), the weighing machine 22 is re-weighed after the first coping message is displayed, and the re-weighed weight Wm is temporarily stored in the work area WA of the RAM 31C (ST20 in FIG. 5). ..

One of the handling message re-display means (31
A, 31B, 14) is carried by the customer into the carry-in conveyor 21
The second countermeasure message (for example, "Please remove the product on the conveyor and place the scanned product" or "Cannot proceed further until the mistaken product placed on the top is removed. Please replace it with a product "). That is, when the re-weighed weight Wm does not become zero (0) (NO in ST21), it is displayed again (ST23). Further, in this embodiment, the buzzer 17 is sounded and a re-alarm is issued. The reweighing timing is set to be repeated because the customer does not know when to remove the defective product from the carry-in conveyor 21 (ST2).
0-22). Then, if it is not removed even after the set time Ts has elapsed (YES in ST22), re-display / re-alarm is performed.

The re-display / re-alarm execution time can be set appropriately. Further, the content of the second coping message to be displayed again may be the same as that of the first coping message at first, and it is possible to implement by constructing such that the speech is made strong and the alarm sound is gradually raised with each repetition. ..

Next, the operation of this embodiment will be described. A customer who has placed a large number of purchased products in a cart stops at the operation unit 10 shown in FIG. 3 and turns on the start switch 15. Then, the CPU 31A causes the display 14 to display a handling message "Please scan the product". The product data D self-scanned by the customer using the product reading means 11 is R forming a scanning product data storage means.
It is temporarily stored in the work area WA of the AM 31C. At this time, the CPU 31A sets the weight Wd of the product corresponding to the scanning product data D to the product data file (D
It is read from A) and temporarily stored in the work area WA.

Then, the display 14 displays a handling message "Place the scanned product in the frame of the conveyor". The product placed on the carry-in conveyor 21 is automatically weighed by the weighing device 22, and the weighed product weight Wm is the RAM forming the weighed product weight data storage means.
It is stored in 31C (WA) (ST10 in FIG. 4).

Here, the weight comparison and determination means (CPU 31
A, ROM31B) input data is normal (ST
11 and 12), and the product weight data Wd and the measured weight data Wm are judged to be the same (ST13). That is, when it is determined that Wm = Wd (YES in ST13),
The CPU 31A forming the conveyor operation control means outputs a transfer operation command signal to the conveyor controller 29 to start the transfer driving operation of the carry-in conveyor 21 (ST1.
4).

On the other hand, when Wm ≠ Wd (N in ST13)
In (O), the CPU3 forming the countermeasure message display means
1A causes the display 14 to display a first coping message such as "Please place the scanned product on the carry-in conveyor" (ST16). In this case, the carry-in conveyor 2
No. 1 is not operated and remains stopped. The same applies when the input data is out of order (NO in ST12). An alarm is also issued.

By the way, a countermeasure message display means (31
Even if the first coping message is displayed (alarm is also given) in A, 31B, 14), the customer does not notice the message, and the wrong product, that is, the wrong product different from the product inadvertently or intentionally scanned, is displayed. Unless it is removed from the carry-in conveyor 21, the reweighing control means (31A, 3A)
1B) re-weighs the weighing device 22 (ST2 in FIG. 5).
0). If the re-weighed weight Wm is zero (0), there is no problem because the mistaken product has already been removed, but if it is not zero (0) even after the set time Ts has passed (YES in ST22), a message to be dealt with Redisplay means (31A, 31B, 14)
Works, and the second countermeasure message is displayed again on the display 14 for a predetermined time (ST23). A re-alarm is also issued. This second coping message is repeated until the customer removes the mistaken product (ST20-23).

Now, the product which is determined to be the same (same weight) as the product self-scanned and the product placed on the carry-in conveyor 21 (YES in ST13) is moved downward by the carry-in conveyor 21 in FIG. Sent to the unloading conveyor 4
1 to the stock location 51.

During this process, when the sensor 23 detects a product, the scanning product data storage means (RAM 31) is first.
The scanning product data temporarily stored in C) is
It is registered in the sales registration storage area RM by the CPU 31A (ST15). At the same time, the conveyor controller 29 stops the carry-in conveyor 21.

Thereafter, the CPU 31A causes the display 14 to display a handling message such as "Please scan the next product" and "Press the stop switch" (ST17). The same applies to the following products (ST10-2
It is handled in 3). When self-scanning is completed for all products and the stop switch 16 is pressed, the self-scanning work is completed.

After that, the electronic cash register 31
The total amount and the like are displayed on the display devices 35 and 36, and the customer pays at the settlement unit 30. For a product temporarily placed on the shelf 15 due to a self-scanning malfunction, the cashier is manually input using the keyboard 32 or the scanner 33. The settled customer bags the product in the stock / bag unit 50.

However, according to this embodiment, the operation unit 1
In the self-scanning system device 1 in which 0, the carry-in / weighing unit 20, the carry-out unit 40, and the stock / bagging unit 50 are arranged in a row in the product flow direction and provided with the weight comparison / determination means,
A countermeasure message display means (31A, 31B, 14), a reweighing control means (31A, 31B) and a countermeasure message redisplay means (31A, 31B, 14) are provided, and Wm ≠ in the weight comparison and determination means (31A, 31B). When it is determined to be Wd, the first countermeasure message is displayed, and the second countermeasure message is displayed again until the re-weighed weight Wm becomes zero (0). The placement can be noticed promptly and surely.

Further, the coping message re-display means (31
Since the buzzer 17 is made to ring together with the re-display by A, 31B, 14), the customer can be more reminded.

Further, a countermeasure message display means (31A,
31B, 14) and the second coping message by the coping message re-displaying means (31A, 31B, 14) can be different, so that the second coping message can be strengthened or even more time-dependent. You can switch to a simple one. The same applies to the pitch of the re-alarm sound.

Further, the second coping message and the re-alarm are repeated re-weighing (ST20 to 22), it is judged that the weighed weight Wm is not zero (0), and the set time Ts.
Since it is executed after the lapse of time, the customer's alerting power can be more strongly evoked, and the customer is not anxious due to unnecessary repeated re-display / re-alarm within an extremely short time.

Furthermore, since the weighing device 22 may be constructed so as to contact the stopped carry-in conveyor 21 to weigh the weight of the product, it is very small and highly accurate. Therefore, the present invention has wide applicability that can be introduced into a multi-product store with a small weight difference, and a stable operation is assured.

Although the above self-scanning system device 1 was introduced into the two-lane dedicated check-out device, it can be implemented as it is as a self-scanning system device for the dual-purpose check-out device disclosed in the above publication. ..
