<p>PROBLEM TO BE SOLVED: To provide a terminal retrieval device, a position information processing system and a storage medium by which the relative distance between this terminal and another terminal. SOLUTION: In this position information processing system 1 in which a plurality of portable terminals 3 and a system controller 2 are connected mutually to be communicated through a network, when an optional portable terminal 3A transmits a request for confirming the relative distance from other user terminals to the controller 2, the controller 2 acquires the position information of the respective portable terminals 3B in response to the request from the portable terminal 3A, calculates the distance between the terminal 3A being a confirmation request source and each of the other portable terminals 3B and transmits the identification information and distance information of other user terminals 3 existing within a prescribed range from the terminal 3A being the confirmation request source to the terminal 3 being the confirmation request source.</p> |
