FIG. 4 is a flow chart showing the operation of this embodiment. First, it is determined whether or not the curtain 12 is closed based on a signal from the curtain opening / closing detection sensor 18 (S100). Here, the customer 13 carries the commodity 15 through the curtain 12 into the fitting room 11 and the curtain 12
When the curtain is closed, the curtain open / close detection sensor 18
2 is detected and the signal is sent to the interrogator 14
Is output to determine that the curtain 12 has been closed.

If it is determined in S100 that the curtain 12 has been closed, the product is detected (S101).
That is, the interrogator 14 emits a radio wave to the tag 16,
The interrogator 1 receives the memory information received by the tag 16 and stored in the tag 16.
The product is detected by replying to 4. S1
If 00 does not determine that the curtain 12 has been closed,

Then, the display control section 31 calculates the total number of detected products (S102), and displays the calculated total number on the display panel 32 (S103). In the example shown in FIG. 3, the number of products is two. Since there may be undetected products depending on the angle of the carried-in product and the radio wave condition, it is determined whether or not the curtain 12 has been opened (S104), and detection of the product is performed until the curtain 12 is opened. The calculation / display of the total number (S101 to S103) is repeated.

When the customer 13 has tried on the curtain and opened the curtain in S104 and it is determined that the curtain 12 has been opened, the total number of detected products is cleared to zero (S10).
5) and returns to S100. When the total number of products is cleared to zero, the display on the display panel 32 of the brought-in product external display device 17 becomes zero.

In this embodiment, since the number of products brought into the fitting room is displayed on the carry-in goods external display device installed outside the fitting room, the following can be achieved. 1.

Not only the store clerk but also other customers in the store can understand the use situation of the fitting room. 4. Since indicating the number of brought-in products also indicates the use situation of the fitting room, not only the clerk but also other customers in the store look at the brought-in product external display device. As a result, it becomes possible not only to monitor shoplifting by a store clerk, but also to check shoplifting by other customers in the store.

5. Even if the clerk is away from the fitting room,
You can see that multiple products were brought in. 6. When the customer leaves the fitting room while carrying the product (shoplifting), the difference between the number of brought-in products and the number of brought-out products can be visually confirmed by the surrounding store clerk or the customer. This makes shoplifting difficult and has a deterrent effect on those trying to shoplift. 7. If a customer who is not intended for shoplifting brings in multiple products, the number of products brought in is displayed outside the fitting room, and since it is possible to publicize the bring-in of multiple products, he is trying to steal just because he brought in multiple products. It can be made public that it is not. Therefore, it has the effect of reassuring the customer. 8. Even if the customer who intends to shoplift does not detect the tag in the fitting room, since the display device for the detected product is provided outside the fitting room, it is not known from the fitting room whether or not the tag is detected.
