Portable communication device
First Claim
1. A portable communication device comprising:
- location data receiving means for receiving reference location data from a plurality of location base stations provided on satellites and/or the ground, location detection means for detecting location information indicating a location of the device based on the reference location data received by the location data receiving means, information input means for inputting identifying information of a communication terminal device to which the location information is to be transmitted, a send key to be manipulated when the location information is transmitted to the communication terminal device, and transmitting means for converting the location information detected by the location detection means to a radio signal and transmitting the radio signal to the communication terminal device having the inputted identifying information via a switching office of the telephone line network, when the transmitting key is manipulated.

Abstract
The present invention provides a portable communication device comprises a GPS antenna, a GPS processing circuit for determining a location of the device based on a signal received by the antenna, a location information processing circuit for detecting the location information corresponding to the determined result, a key input device for inputting a telephone number of a communication terminal device for transmitting the location information, a control circuit, and a transmitting circuit. The key input device is provided with a LOST key. The control circuit feeds the location information detected by the location information processing circuit to the transmitting circuit when the LOST key is manipulated. The transmitting circuit transmits the location information to the communication terminal device having the inputted telephone number. This realizes the portable communication device which is adapted to notify the others of the accurate present location of the device.
