DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS An embodiment of the present invention will be described below with reference to FIGS. It should be noted that components having the same functions as those of the conventional example shown in FIG.

1 to 3 show a first embodiment. As shown in FIG. 3, a loop antenna 10 is embedded in the outer periphery of the store-side opening 9 of the showcase 2, and the loop antenna 10 includes a tag receiving unit 11 and a PLU code selecting unit 1.
It is connected to the toll control unit 7 via 2. Tags 14 are attached to the trays 3a, 3b, ... As containers displayed on the shelf 13 of the showcase 2. Further, the loop antenna 10 is connected to a carrier transmitter 15 that transmits an AC signal.

The tag 14 is constructed as shown in FIG. The tag 14 rectifies an AC signal from the PLU code storage unit 16 in which the PLU code of the product placed on its own tray is written, the loop antenna 17, and the carrier transmission unit 15 generated in the loop antenna 17. The rectification unit 18 that supplies the electric power in the tag 14 and the rectification unit 18
When a specified voltage is generated in the output of the tag control unit 19, a tag control unit 19 that reads the PLU code from the PLU code storage unit 16 and instructs transmission, and a PLU instructed by the tag control unit 19
The transmission unit 20 is configured to send a code to the loop antenna 17 and transmit the code at a frequency different from the AC signal of the carrier transmission unit 15.

The showcase 2 has tags 14 attached to the trays 3a, 3b, ... In the standby state for sale.
Is located outside the service area 21 of the AC signal generated from the loop antenna 10, and the store clerk puts the target product on the shelf 3b, for example, on the tray 3b.
When pulled out from 3, the tag 14 attached to the tray 3b crosses the service area 21.

At this time, the tag controller 19 of the tag 14 transmits the PLU data via the transmitter 20 and the loop antenna 17. The transmitted PLU data is input to the tag receiving unit 11 via the loop antenna 10 and reproduced,
It is supplied to the toll control unit 7 via the LU code selection unit 12. The charge control unit 7 searches the PLU memory 1, reads the PLU data specified by the input PLU code, and reads the weight value of the balance unit 4 from the PLU.
The selling price is calculated by processing based on the data and displayed on the display unit 8. Further, when the receipt printer or the label issuing machine is installed, the toll-balance control unit 7 is set to P
Instruct to print the contents of LU data and selling price.

In this way, the clerk A can carry out the information processing only by pulling out the desired tray 3b and placing the required amount of the product on the balance section 4, and the information processing can be carried out as in the conventional case by using the keyboard 6. No key-in operation of PLU code is required.

When the PLU code from the keyboard 6 is keyed in prior to the PLU code of the tag receiving unit 11, the PLU code selecting unit 12 supplies the PLU code from the keyboard 6 to the charging control unit 7. . Keyboard 6 behind the PLU code of tag receiver 11
When the key-in is performed from, the PLU code used for information processing in the toll-balance control unit 7 is corrected to the key-in code from the keyboard 6 in order from all digits or the lower digits.

Further, as shown in FIG. 4, the battery 2 is attached to the tag 14.
2, and the tag control unit 19 uses the transmission instruction switch 2
3 is detected, the PLU code read from the PLU code storage unit 16 is transmitted from the transmission unit 20 to the antenna 24.
The loop antenna 10 on the fixed side may be a small antenna dedicated to reception by being configured to transmit at.

In the embodiment shown in FIG. 4, the PLU code is transmitted when the transmission instruction switch 23 is operated by the store clerk, but the human body touches the tray as shown in FIG. A touch sensor 25 for detecting that the touch sensor 25 is provided, and the tag control unit 19 transmits the PLU code read from the PLU code storage unit 16 from the transmission unit 20 through the antenna 24 when the touch sensor 25 detects the contact with the human body. With the configuration, the operation of the transmission instruction switch 23 can be made unnecessary.

When the tray of the touch sensor 25 is made of metal, the electrode 26 of the touch sensor 25 is connected to the tray, and when the clerk grips the tray to take it out of the shelf 13, the electrode 26 is attached to the electrode 26 via the tray. The radio wave guided to the clerk's body is applied, the touch sensor 25 rectifies and smoothes the signal of the electrode 26, and the level thereof is determined to determine whether or not the human body is in contact.

In the embodiment shown in FIGS. 4 and 5, the secondary battery is incorporated in the tag 14 as the battery 22, but instead of the battery 22, a solar battery is provided in the tag 14 to supply electric power. The same applies to the case of the configuration. In the case of using a solar cell, the light energy of the illumination light source of the showcase 2 is converted into power source power.

[0026]

As described above, according to the present invention, when the tray containing the merchandise to be sold by weight is taken out from the product case, when the tag attached to the tray passes through the product loading / unloading port of the product case, The tag activation means operates and the product code of the product is transmitted from the tag by a wireless signal. This product code is received by the wireless reception unit of the electronic charge balancer, and the calculation control unit reads the unit price based on the received product code and calculates the price of the product based on the read unit price and the measured value. It is output after being processed and the operability is further improved.

As the antenna used for communication with the tag, a single loop antenna is arranged along the outer periphery of the product inlet / outlet of the product case, so that the tag of any tray displayed in each place of the product case With this, reliable communication can be realized, and it does not prevent the tray from being taken out.

[0028] Therefore, the electronic charge balancer, which is used in a sales form in which there are many kinds of products such as meat and side dishes and the prices are diverse and is sold in small quantities, is made easier to use. It is possible to realize a system in which even a salesclerk who is not good at operation can sell without mistake.

Further, when the activation means provided in the tag is a touch sensor connected to the metal tray, when a store clerk touches the tray, the touch sensor as the activation means detects this and the product The product code is transmitted from the tag by a wireless signal. This product code is received by the wireless reception unit of the electronic charge balancer, and the calculation control unit reads the unit price based on the received product code and calculates the price of the product based on the read unit price and the measured value. It is output after being processed and the operability is further improved.
