Abstract

PROBLEM TO BE SOLVED: To dynamically indicate a tag to be operated by adding an indication means for showing that the tag is to be operated. SOLUTION: An interrogator 110 transmits an identification code (ID) of a tag to be operated as an interrogation wave. A responding circuit 230 demodulates the ID of the tag to be operated from the interrogation wave received by a reception antenna 120 to compare it with identification information. When they are in conformity with each other, a light emitting device controlling means 260 is instructed to flash a light emitting device 270 (indication means). It is easy for an operator to observe the tag to be operated by the flashing of the light emitting element 270, then the operator can easily apply a pressure to the tag. The pressure is transmitted to a detection element 170 to vary its resistance value. Then a pressure detecting circuit 210 operates to activate the responding circuit 230. The responding circuit 230 instructs the controlling circuit 260 to stop the flashing of the light emitting element 270 and transmits a response wave to the interrogator 110 or a receiving device exclusive for the response wave via a transmission antenna 140.

However, in the conventional tags, there is no function of dynamically indicating the tag to be operated, so there is a problem that the user needs to find out the tag to be operated by himself. It was

It is an object of the present invention to dynamically indicate a tag to be operated by adding means for indicating the tag to be operated to the tag.

[0006]

In order to solve the above-mentioned problems, the present invention demodulates the inquiry radio wave in a tag which receives the radio wave from the interrogator and transmits the stored unique identification information. Display means for displaying that the tag is a tag to be operated when the obtained ID information matches the identification information, and the display when the operator performs a predetermined operation on the tag. And a response means for transmitting the identification information at the same time.

[0007]

According to the present invention, in the tag which receives the radio wave from the interrogator and transmits the stored unique identification information, the display means stores the ID information obtained by demodulating the interrogation radio wave and the tag. When the identification information matches the tag, the tag indicates that the tag is to be operated, and the response unit terminates the display when the operator performs a predetermined operation on the tag and the identification information. To send. Therefore, the operator does not have to find out the tag to be operated,
The above problems can be solved.

The tag ID to be operated is transmitted as an inquiry radio wave.
The response circuit 230 demodulates the ID of the tag to be operated from the interrogation radio wave received by the receiving antenna 120 and compares it with the identification information. At this time, if they match, the light emitting element control means 260 is instructed to blink the light emitting element 270. In the light emitting element control means 260, the response circuit 230 changes the electrical resistance value of the pressure detecting element 170.
The light emitting element 270 continues to blink at a certain interval until it is detected by 10. Since the tag to be operated can be easily found by the blinking of the light emitting element, the operator can operate the packaging material cover 160 of the tag 100 or the packaging material substrate 150.
