<P>PROBLEM TO BE SOLVED: To provide a portable machine capable of securing a high security level without deteriorating usability. <P>SOLUTION: This portable machine 1 comprises a control portion 11, and a positional information acquiring portion 13 for acquiring its own positional information. The control portion 11 is equipped with a memory 11c in which preset updated positional information and preset use limit values are recorded. The control portion 11 reads out the use limit value from the memory 11c, and inhibits the transmission of an operation signal when an elapsed time (a timer count value) and the number of the transmissions of the operation signal (a transmission count value) reach the use limit values. Additionally, the control portion 11 automatically updates the timer count value and the transmission count value to an initial state, when it is determined that positional data acquired by the positional information acquiring portion 13 correspond to the updated positional information recorded in the memory 11c. <P>COPYRIGHT: (C)2008,JPO&INPIT |
