Abstract
A non-contact IC tag of the present invention includes a first member including an IC chip and a first antenna connected to the IC chip; a second member including a second antenna; and a movement restriction unit that, when the first member is moved to a predetermined position in the second member, restricts a movement of the first member from the predetermined position. The predetermined position is a position where the first antenna and the second antenna are electromagnetically coupled to each other or a position where the first antenna and the second antenna are electrically conducted to each other.
Claims8
A non-contact IC tag comprising:
- a first member including an IC chip and a first antenna connected to the IC chip;
- a second member including a second antenna;
- and
- a movement restriction unit that, when the first member is moved to a predetermined position in the second member, restricts a movement of the first member from the predetermined position,
- wherein the predetermined position is a position where the first antenna and the second antenna are electromagnetically coupled to each other or a position where the first antenna and the second antenna are electrically conducted to each other;
- a coupling unit couples the first member and the second member to one another so that the first member being displacable relative to the second member;
- the first member is rotatable, with respect to the second member, by the coupling unit about a predetermined rotational axis;
- and
- the first member is displaceable between a predetermined position and a position displaced from the predetermined position.
A non-contact IC tag comprising:
- a first member including an IC chip and a first antenna connected to the IC chip;
- a second member including a second antenna;
- a movement restriction unit which, when the first member is moved to a predetermined position in the second member, restricting movement of the first member from the predetermined position;
- the first antenna and the second antenna, in the predetermined position, being one of electromagnetically coupled and electrically conducted to one another;
- the non-contact IC tag having a first communication distance, while in the predetermined position, and the non-contact IC tag having a second communication distance, when moved out of the predetermined position;
- and
- the first communication distance that being at least three orders of magnitude greater than the second communication distance.
