PROBLEM TO BE SOLVED: To solve the problem of complicated remote operation as in a conventional case and the problem of a timer that needs to be set again when home- coming time changes, and of the fact that the remote operation greatly depends on the installation position of a base station and the size of a radio zone. SOLUTION: A position information detection part 6 calculates the position information (latitude and longitude) of a current position by utilizing an inputted GPS. A mail automatic transmission part 7 monitors whether the current position of a radio portable terminal has reached distance to one's house for automatic mail transmission or not based on the current position information of the radio portable terminal that is detected and calculated by the position information detection part 6, the position information of one's house that is read through a control part 2 from a storage part 4 and distance information to one's house, and sends a mail with details having been registered at the storage part 4 in advance to one's house through the control part 2 and a radio part 1 when it is judged that the current position of the radio portable terminal has reached distance to one's house for automatic mail transmission. |
