Abstract

According to the present invention, the component selection information sent out from the signal transmitter to the electronic tag attached to the component is collated in the electronic tag with the component identification information recorded in the electronic tag, so that the notifying device notifies the collation result, as a result of which the selected component can be easily recognized by the notification. Additionally, according to the present invention, a write signal is sent out from the signal transmitter to the electronic tag. When the electronic tag receives the write signal, the component identification information is written in the electronic tag. Therefore, it is possible to write the component identification information in the electronic tag in a state in which the electronic tag is attached to the component.

Claims

1. An electronic tag attached to a component, comprising:

a recording device which records component identification information of the component to which the electronic tag is attached;

a receiving device which receives a component selection signal containing component selection information sent out from a signal transmitter using an electromagnetic wave;

a collating device which collates the component selection information contained in the component selection signal acquired by the receiving device with the component identification information recorded in the recording device; and

a notifying device which notifies the result of collation performed by the collating device.

2. The electronic tag according to claim 1, wherein the notifying device comprises a magnetizing device, and wherein when the component selection information coincides with the component identification information as a result of collation performed by the collating device, the magnetizing device is magnetized.

3. The electronic tag according to claim 1, wherein the notifying device comprises a light emitting device, and wherein when the component selection information coincides with the component identification information as a result of collation performed by the collating device, the light emitting device is made to emit light.

4. The electronic tag according to claim 1, further comprising a component identification information writing device for writing the component identification information in the recording device, when receiving a write signal containing the component identification information of the component to which the electronic tag is attached.

5. The electronic tag according to claim 2, further comprising a component identification information writing device for writing the component identification information in the recording device, when receiving a write signal containing the component identification information of the component to which the electronic tag is attached.

6.

wherein the signal transmitter comprises a signal transmission device which sends out a component selection signal containing component selection information for selecting a component to which the electronic tag is attached,

and wherein the electronic tag comprises;

a receiving device which receives the component selection signal sent out from the signal transmitter;

a recording device which records component identification information of a component to which the electronic tag is attached;

a collating device which collates the component selection information contained in a radio signal received by the receiving device with the component identification information recorded in the recording device; and

a notifying device which notifies the result of collation performed by the collating device.

14. The component selection system according to claim 13, further comprising a component taking-out device which selectively takes out a desired component from a mixture of a number of components, based on the collation result from the notifying device.

15. The component selection system according to claim 13, wherein the signal transmitter comprises a component identification information storing device which stores the component identification information to be written in the electronic tag, and wherein the signal transmitter sends out to the electronic tag a write signal containing component identification information selected from the component identification information stored in the component identification information storing device.

16. The component selection system according to claim 14, wherein the signal transmitter comprises a component identification information storing device which stores the component identification information to be written in the electronic tag, and wherein the signal transmitter sends out to the electronic tag a write signal containing component identification information selected from the component identification information stored in the component identification information storing device.

17.
