Abstract

A non-contact power reception apparatus is provided, in which a power reception coil for a charging system and a loop antenna for an electronic settlement system are mounted on a battery pack and a cover case of a portable terminal such that the power reception coil is arranged in the center thereof and the loop antenna is disposed outside the power reception coil, so that a mode of receiving a wireless power signal and a mode of transmitting and receiving data are selectively performed, thereby preventing interference from harmonic components and enabling non-contact charging and electronic settlement using a single portable terminal. A jig for fabricating a core to be mounted to the non-contact power reception apparatus is provided.

Claims

1-15. -15. (canceled)

16. A common transmission and reception module provided to a portable terminal to enable non-contact charging and a wireless communication, the module comprising:

a power reception coil which has a plurality of planar windings to receive a wireless power signal from a non-contact power transmission apparatus and is configured to provide the wireless power signal to the portable terminal when electrically connected to the portable terminal;

a communication antenna which loops outside the power reception coil, is arranged on the same plane with the power reception coil, and is configured to wirelessly transmit or receive data with an external electronic device when electrically connected to the portable terminal; and

the connector which allows an electrical connection between the portable terminal and at least one of the power reception coil and the communication antenna.

17. The module of claim 16, wherein the communication antenna is used for electronic payment based on the data, and the data includes information regarding the electronic payment.

18. The module of claim 16, wherein the power reception coil is configured to be connected to a rectification block of the portable terminal and the communication antenna is configured to be connected to a data processor of the portable terminal.

19. The module of claim 16, wherein the power reception coil is configured to be connected to a rectification block of the portable terminal and the communication antenna is configured to be connected to a data processor of the portable terminal through the connector.

20. The module of claim 16, wherein the power reception coil is circular and made of a thin metal wire.

21. A portable terminal comprising:
