Description

[Detailed description of the invention]

0001

[Field of Industrial Application] The present invention relates to a personal data identification device, and more particularly to a personal data identification device carried by an individual to identify individual data when entering or exiting a specific place. .

0002

[Prior Art] Conventionally, this type of personal data identification device
Due to differences in the recording medium of personal data, magnetic cards and IC
The support is made of a card-shaped plastic called an ID card, and personal data is recorded on a magnetic film or ROMIC.

For example, as shown in FIG. 9, a personal data identification device using a magnetic card has a support body 41 and a magnetic film 42 as basic elements, and is usually about 1 mm thick to be suitable for carrying. A magnetic film 42 is pasted in the form of a band onto a support 41 made of plastic or the like, and personal data is recorded and held as the distribution of magnetic polarity and strength. This personal data is read by a magnetic reader using a magnetic head as a sensor.

[0004] In addition, in a personal data identification device related to an IC card, a ROMIC and a ROMIC that record personal data are used.
An electrical contact for reading out the stored contents is bonded to or embedded in the support, and is read as an electrical signal by a reading device.

[0005]

[Problems to be Solved by the Invention] However, in the former type of personal data identification device that uses a magnetic card, the information to be magnetically recorded is stored by magnetic powder coated on the film. Since the information is recorded magnetically, the signal output of the recorded information is extremely weak, and
The relative speed of the magnetic card when reading with the magnetic head must be within a certain range.Furthermore, because the recorded information changes in a strong magnetic field, the relative speed of the magnetic card must be adjusted by making contact between the magnetic head and the magnetic card. There was a problem that malfunctions were likely to occur unless the magnetic field was kept within a certain range, and strong magnetic fields had to be avoided. Furthermore, it has the disadvantage that the shape of the support, that is, the magnetic card, must be limited in order to maintain the adhesion of the magnetic film to the magnetic head and the like.

On the other hand, in the latter example using an IC card,
In order to read the recorded contents of ROMIC, electrical contacts are required, and relative positional accuracy with the reading device is required.
As the electrical contacts become more complex and smaller, there is a problem in that the reliability including the durability of the electrical contacts decreases.

The present invention has been made in view of the above-mentioned problems, and an object thereof is to provide a personal data identification device that eliminates restrictions due to contact with a reading device without weakening the signal strength.

The configuration includes a transmitting antenna that converts the high frequency signal of the transmitter into electromagnetic waves and radiates the electromagnetic waves into space.

[0009] Also, a receiving antenna that receives radio waves and outputs a high-frequency signal, a rectifying circuit that rectifies the output of the receiving antenna and outputs DC power, and a rectifying circuit that is activated by the DC power that is the output of the rectifying circuit and collects personal data. a code generation circuit that generates a code signal corresponding to , a transmitter that outputs a high-frequency signal modulated by the output of the code generation circuit, and a transmitting antenna that converts the high-frequency signal of the transmitter as an electromagnetic wave and radiates it into space. It has a configuration that includes the following.

[Operation] According to the personal data identification device having the above configuration, since the reading device outputs electromagnetic waves to read personal data, the signal strength is ensured, and
Signal transfer is performed without contact with the reading device.
