Description

DETAILED DESCRIPTION OF THE INVENTION A. Field of Industrial Application The present invention relates to an information card, and is particularly suitable for application to an information card mounted with a power source battery.

B. Summary of the Invention The present invention provides an information card mounted with a power battery, in which a power battery holder provided on a terminal board is brought into contact with a first electrode surface of the power battery, and a part of the terminal board is brought into contact with a first electrode surface of the power battery. By contacting the second electrode surface of the power supply battery, a thin information card can be constructed.

C. Prior art As an information card reading device for reading information on a conventional information card, for example, 2.45 (GHz) is used as shown in FIG.
A response request signal wi using a microwave as a carrier wave is generated in the response request signal generating circuit 2 of the information reading device l, and is emitted from the transmitting antenna 3 to the information card 4, and the response information signal is returned from the information card 4. By taking W2 into the response signal processing circuit 6 via the receiving antenna 5 of the information reading device 1, it is possible to detect the information card 4, for example, by a person entering or exiting the gate who carries the information card 4 as a person's exit card, or by cargo attached with the information card 4 as a tag. It is being considered to build an information card reading system that can check the information card.

The information card 4 applicable to such an information card reading system includes a dipole antenna 4B attached to a wiring board 4A to form part of a wiring pattern, and an integrated circuit (IC) forming an information signal generation circuit. A wiring pattern 4 connects the information signal generating circuit 4c of the configuration and the power supply battery 4D.
By changing the impedance at the feeding point of the dipole antenna 4B in accordance with the information signal generated by the information signal generation circuit 4C, the reflectance for the carrier wave emitted from the information reading device 1 as the response request signal W1 can be increased. A method has been proposed in which the reflected wave is returned as a response information signal W2 by changing the response information signal W2 (Japanese Patent Application No. 63-6292).

The information signal generation circuit 4C has an electrical circuit B configuration as shown in FIG. The address signal S3 of the address counter 13 that performs a counting operation is read out by the address signal S3, and is supplied to the variable impedance circuit 14 made of, for example, a field effect transistor.

The variable impedance circuit 14 has a pair of feed point terminals T1
and T2, and when the information data S1 becomes logic "1" or logic "0", the field effect transistor turns on or off, and the feed point terminal T
The impedance at the feeding point of the dipole antenna 4B connected to T1 and T2 is variably controlled, and thus the reflectance for the response request signal w1 incident on the dipole antenna 4B is variably controlled.

A power supply battery 4D is connected between the ground side feed point terminal T1 and the power supply terminal 73 of the information signal generation circuit 4C, and thereby the impedance variable control at the feed point of the dipole antenna 4B is always and continuously performed using the information data S1. It is made to be obtained.

A unique identification code is assigned to each information card 4 in the information memory 11, so that the information reading device 1 can reliably read the information held by the information card 4.

Problems to be Solved by the Invention Since the information card 4 is carried by a user or attached to an item, it is necessary to make it as small and thin as possible to improve usability.

Therefore, if a thin so-called vapor battery, for example, can be mounted as thinly as possible as the t-source battery 4D mounted on the information card 4, it is considered that the information card as a whole can be made thinner.
