The host device 7 is provided with the article management means of the present invention.

FIG. 2 is a schematic perspective view of the product display shelf. A method of identifying a customer who is close to the product display shelf 2 will be described with reference to FIG. A plurality of products 10 are stored in the product display shelf 2, and each product 10 has a product identification medium 1
0a (which is the radio wave type label of the present invention) is attached. The customer identification code reading unit 3 provided corresponding to the display position of each product on the product display shelf 2 detects the proximity state of the customer to the product display shelf 2 with the proximity sensor, and outputs a power carrier when the customer is detected. . Specifically, when the proximity sensor detects that there is a customer in the vicinity for a certain period of time, the power carrier is output. The power carrier output in this manner is output only to the area where the proximity sensor can detect the proximity of the customer. That is, the customer identification code of only the customer in front of the product display shelf 2 can be read by the configuration described below.

Here, the customer has the customer identification medium 11. FIG. 3 is a diagram showing the structure of the customer identification medium.
The customer identification medium 11 includes a CPU 12, a ROM 13, and an R
The AM 14 includes a communication unit 15 that performs wireless communication, and a power supply circuit 16 that supplies operating power. Communication unit 15
Is equipped with an antenna 15a, and the RAM 14 stores a customer identification code for identifying a customer. Customer identification medium 11
When the antenna 15a receives the electric power carrier, the communication unit 15 sends the electric power carrier to the power supply circuit 16, and the power supply circuit 16 extracts the operating power supply from the electric power carrier and the CPU
12 supplies electric power required for operation. CPU 12
When power is supplied, the communication unit 15 outputs the customer identification code stored in the RAM 14 as a wireless signal. That is, when the customer identification code reading unit 3 detects the proximity of the customer to the product display shelf 2, it outputs a power carrier wave. In this way, the electric power carrier wave output from the customer identification code reading unit 3 is received by the customer identification medium 11 possessed by the customer who approaches the product display shelf 2. The customer identification medium 11 obtains operating power by receiving the power carrier wave, and outputs the customer identification code stored in the RAM 14 from the communication unit 15 as a wireless signal. This customer identification code is received by the customer identification code reading section 3. Therefore, the customer can be identified by reading the customer identification code from the customer identification medium 11 possessed by the customer who has approached the product display shelf 2.

Next, the product identification code reading section 4 performs a process of detecting the taking out of the product from the product display shelf 2 and the storage of the product in the product display shelf 2. Product identification code reading section 4
For example, the two sensors 21 and 22 detect whether the article is taken out of the commodity display shelf 2 or stored in the commodity display shelf 2. For example, of the two sensors 21 and 22 provided in the product takeout direction, the sensor 21 is an optical sensor, and the sensor 22 is a reading sensor that receives the identification code output from the product identification medium 10a. Here, the product identification medium 10a attached to the product 10 has the same configuration as the customer identification medium 11, and the only difference is that the product identification code is stored in the RAM instead of the customer identification code. Further, the product identification medium 10a also outputs the product identification code as a radio signal when receiving the power carrier. Sensor 22
Always outputs the electric power carrier only to a predetermined area near the takeout side of the product display shelf 2. Here, when the product 10 is stored, the product is detected by the sensor 21 after the product identification medium 10a receives the electric power carrier wave output by the sensor 22 and transmits the product identification code. When the product 10 is taken out, after the product is detected by the sensor 21, the product identification medium 10a receives the electric power carrier wave output by the sensor 22 and transmits the product identification code. That is, when the sensor 21 detects the movement of the product and then the sensor 22 receives the product identification code, it is determined that the product 10 has been taken out, and after the sensor 22 receives the product identification code, the sensor 21 detects the movement of the product. When it does, it can be determined that the product 10 has been returned.

The two sensors 21 and 22 are optical sensors, and when the movement of the goods is detected in the order of the sensors 22 and 21, it is judged that the goods are stored, and the sensors 21 and 22 are stored.
It may be determined that the product is taken out when the movement of the product is detected in the order of the sensors 22. In this case, the product identification code reading unit 4 outputs a power carrier when detecting the movement of the product by the sensors 21 and 22 in either direction, and causes the product identification medium 10a to output the product identification code as a wireless signal. You can do it. By receiving the product identification code output in this way, the product identification code reading unit 4 determines whether the product is taken out from the product display shelf 2 or stored, and the product identification code of the product is displayed. Can be read.

Although the movement of the article is detected by the two sensors 21 and 22 in this embodiment, the number of sensors is not limited to two and may be three or more. Further, the sensor is an optical sensor or a reading sensor, but other sensors may be used to detect the movement of the product.

In the host device 7, the PLU file in which the product identification code and the price are registered in correspondence with each product, the customer identification code, the product identification code of the product to be traded, and the price of the product are associated with each customer. The transaction data file 7a (see FIG. 4) to be registered is provided, and the product management file 7b (see FIG. 5) that manages the stock number (the number displayed on the product display shelf) for each product 10 is provided.

FIG. 6, FIG. 7 and FIG. 8 are diagrams showing processing when shopping is carried out in a store to which the article management apparatus according to the embodiment of the present invention is applied. Upon entering the store, the customer receives the customer identification medium 11 storing the customer identification code. The customer identification medium 11 may be issued to the customer in advance. In this case, the customer does not need to receive the customer identification medium 11 from the store. While moving in the store, the customer goes in front of the product display shelf 2 on which the products to be purchased are displayed.

When the customer identification code reading section 3 detects the proximity of the customer to the product display shelf 2 (n1), it performs a process of reading the customer identification code from the customer identification medium 11 possessed by the customer (n2). Here, a case where the customer identification code is not correctly read will be described later (n3 →
n11). After that, when the product identification code reading unit 4 detects the movement of the product displayed on the product display shelf 2 (n
4) The product identification code is read from the product identification medium 10a attached to the product 10 by performing the above-described processing, and the product 10 is returned from the product display shelf 2 or returned (stored). ) Is determined (n4 → n
5 → n6 → n7). Here, a case where the product identification code is not correctly read will be described later (n6 → n).
11). When it is determined that the product 10 has been taken out, a registration request for the product 10 including the customer identification code read out in n2 and the product identification code read out in n5 is transmitted to the host device 7 (n8), and the signal generating unit is also sent. An OK signal is output from 5 (n9).

On the other hand, if it is determined in n7 that the product 10 has been returned, a registration cancellation request for the product 10 including the customer identification code read in n2 and the product identification code read in n5 is transmitted to the host device 7 ( n10), and the OK signal is output from the signal generator 5 (n9).

When a registration request or a cancellation request for the product 10 is sent to the host device 7 (n31, n35),
The transaction data file 7a of the corresponding customer identification code is searched (n32, n36). When the registration request for the product 10 has been sent, the product identification code and the price sent in the transaction data file 7a searched in n32 are registered in correspondence (transaction data registration) (n33). At this time, the price of the product is retrieved by searching the PLU file. Then, the stock quantity of the corresponding product 10 registered in the product management file 7b is updated (n25). To update the stock quantity, the quantity of the product 10 for which the removal is detected is subtracted from the stock quantity, and this value is registered as a new stock quantity.

When the cancellation request for the product 10 is sent, the data registered in correspondence with the product identification code and the price sent in the transaction data file 7a searched in n32 is canceled ( n37). And
Corresponding product 1 registered in the product management file 7b
The stock quantity of 0 is updated (n38). To update the stock quantity, add the quantity of the product 10 detected to move to the stock quantity,
This value is registered as a new stock quantity.

That is, the product 10 taken out from the product display shelf 2 for the purpose of being purchased by the customer is registered in the transaction data file 7a of the customer. Further, the product 10 returned (stored) to the product display shelf 2 for the customer to cancel the purchase is
It is canceled (deleted) from the transaction data file 7a. Therefore, the registration can be performed when the product 10 is taken out from the product display shelf 2, and the registration is canceled when the product 10 is returned to the product display shelf 2. In addition, the number of items stored in the item display rack 2 for each item 10 in the item management file 7b (inventory number)
Can be managed in real time.

As described above, the customer takes out the merchandise 10 to be purchased from the merchandise display rack 2 while moving in the store, and when the purchase is stopped, the merchandise 10 is placed on the merchandise display rack 2.
Continue shopping while returning. When the customer moves through the store and takes out all the merchandise 10 to be purchased from the merchandise display shelf 2, the customer goes to the cash register with these merchandise. At the cash register, the transaction processing device 6 outputs a power carrier wave to the customer identification medium 11 owned by the customer and reads the customer identification code (n2).
1). At this time, if the customer identification code cannot be read (n22), for example, a cashier inputs the customer identification code from an input unit such as a keyboard as error processing (n2).
6). Then, the transaction processing device 6 transmits to the host device 7 a transaction data transmission request including this customer identification code.

When there is a transaction data transmission request from the transaction processing device 6 (n39), the host device 7 retrieves the transaction data file 7a of the corresponding customer (n40) and transmits it (n41).

The transaction processing device 6 receives the transaction data file 7a of the corresponding customer from the host device 7 (n2
4) The settlement processing such as issuing a receipt in which the commodity registered in the transaction data file 7a and the price of the commodity are printed (n25). The customer pays the transaction amount to the cashier, receives the product 10 and the receipt, packs the purchased product 10 in a bag or the like, and takes it home. When the customer borrows the customer identification medium 11 from the store, the customer returns the customer identification medium 11 when leaving the store.

The transaction amount may be settled in cash or in a credit card in the above embodiment. Alternatively, it may be sold for sale and billed to the customer at a later date. Further, in the above-mentioned embodiment, the cashier is arranged at the cash register, but a cashier may be provided at the exit of the store so that the customer himself can pay the cash. By doing so, it is possible to eliminate the need for a cashier at the store and further reduce labor costs.

Here, a case will be described in which the customer identification code cannot be read accurately at n3 or when the movement of the product is detected at n6. In such a case, the signal generator 5 outputs a warning signal (n11). Then, error processing such as instructing the customer how to respond is performed (n12). As the error processing, for example, the product 1 taken out when the product is taken out
0 is returned to the merchandise display shelf 2, and an instruction is given to take out the merchandise 10 again. Also, if you return the product,
On the contrary, the product is again taken out, and an instruction to return the taken-out product 10 is given. If the customer identification code is not read normally, the customer identification code reading unit 3 reads the customer identification code again. The signal generation unit 5 issues a message prompting the user not to put the product 10 in or out of the display shelf 2.

Further, the commodity display shelf 2 is provided with an input device such as a bar code reader or a keyboard, and when the customer identification code or the product identification code cannot be read accurately, these input devices are used. It may be used to instruct the customer himself to input the product identification code or the customer identification code.

Further, the customer identification medium 11 possessed by the customer is made into a bracelet shape, and in the store, the customer carries this with the commodity 1
It may be attached to the wrist of the hand for taking out and storing 0 (see FIG. 9). In this way, the customer identification code and the product identification code can be read simultaneously by the product identification code reading unit 4 when the product 10 is taken out or stored. Therefore, it is possible to eliminate the customer identification code reading unit 3 and prevent other customers from mistakenly registering the product 10 taken out from the side. That is, as shown in FIG. 9, the two customers A and B have the product display shelves 2
In the case of being in front of the customer, only one customer can specify the person who took out the product 10 even when taking out the product 10.

Further, two customers A and B are almost at the same time as the product 1
It is possible to detect the case where 0 is taken out and the customer identification code of one customer B cannot be read. In this case, for example, the signal generating unit 5 may issue a warning signal and perform error processing such as instructing both the customers A and B to return the above-mentioned product 10 once and take it out again. . That is, it is possible to prevent one customer A from registering two products. Further, since the shape of the bracelet does not cause any discomfort, the customer can carry the customer identification medium 11 and shop in the store.

The product identification code reading section 4 may read the product identification code for the products stored in the product display rack 2 at predetermined intervals, or the product storage rack 2 may be weighed. You may make it detect the gross weight of the goods provided and stored. By doing so, it is possible to confirm whether or not the number of products 10 displayed on the product display shelf 2 managed by the product management file 7b of the host device 7 is correct due to a registration error or the like. . Further, for each product 10, a product management file 7b is used to display the product display shelf 2
Since it is possible to manage the number of items displayed on the display, it is possible to easily replenish the product display shelf 2 with the product 10.

Further, the product management file 7 of the host device 7
