PORTABLE TERMINAL

Document Type and Number:

Japanese Patent JP2008206297

Kind Code:

A

Abstract:

To enable ensuring the reliability of data communication in non-contact communication without deteriorating the characteristics of non-contact point power transmission, without imposing bad effect on the communication performance of a portable terminal and without requiring expensive countermeasures against noises.

The portable telephone terminal includes a secondary coil 14 and a non-contact point power transmission circuit unit 40 for non-contact point power transmission, and a non-contact communication circuit 70 and a loop antenna 71 for non-contact communication. When non-contact communication is performed, the non-contact communication circuit 70 notifies a control circuit 50 of the non-contact point power transmission circuit unit 40 that the non-contact communication will be performed. Upon receiving the notification, the control circuit 50 requests a cradle 1 on a primary side of the non-contact point power transmission to stop power transmission.
