Touch panel, information recording medium, and information acquisition method

1. A touch panel comprising:

a touch detection device;

a map generation section configured to generate a first data map including a fixed pattern and a data pattern, based on a signal output from the touch detection device according to an information recording medium placed in proximity to the touch detection device; and

a data acquisition section configured to identify the fixed pattern, and acquire a data code from the data pattern, based on a result of identifying the fixed pattern,

wherein the fixed pattern allows determining a position and an orientation in which the information recording medium is held over the touch detection device, and

the data acquisition section determines, based on an address in the data pattern of a pattern component in the data pattern, data of a bit corresponding to the address in the data code,

wherein the information recording medium comprises:

a first recording portion in which a plurality of first conductors are arranged in the fixed pattern; and

a second recording portion in which one or a plurality of second conductors are arranged in the pattern corresponding to recording data, wherein the plurality of second conductors comprise two conductors that differ in conductivity from each other.

2. The touch panel according to claim 1 , wherein the map generation section further generates a second data map, based on a signal output from the touch detection device according to a touch by a user, and the touch panel further comprises a touch detection section configured to detect the touch by the user, based on the second data map.

3. The touch panel according to claim 2 , wherein the touch panel has a first operation mode and a second operation mode, the touch detection section detects a touch in the first operation mode, and the data acquisition section acquires the data code in the second operation mode.

4. The touch panel according to claim 1 , wherein the touch detection device is a capacitance detection device.

5. The information recording medium according to claim 1 , wherein the information recording medium is a card, and the first recording portion and the second recording portion are disposed in an internal layer of the card.

6. An information acquisition method comprising:

generating, by a map generation section, a first data map including a fixed pattern and a data pattern, based on a signal output from a touch detection device according to an information recording medium placed in proximity to the touch detection device;

identifying the fixed pattern, and acquiring a data code from the data pattern, based on a result of identifying the fixed pattern;

determining, based on the fixed pattern, a position and an orientation in which the information recording medium is held over the touch detection device; and

determining, by a data acquisition section, based on an address in the data pattern of a pattern component in the data pattern, data of a bit corresponding to the address in the data code,

wherein the information recording medium comprises:

a first recording portion in which a plurality of first conductors are arranged in the fixed pattern; and

a second recording portion in which one or a plurality of second conductors are arranged in the pattern corresponding to recording data, wherein the plurality of second conductors comprise two conductors that differ in conductivity from each other.
