First Claim
1. A portable guide device comprising:
- an acceleration sensor for detecting the acceleration of a portable guide device when it is in motion;
acceleration range storage means for storing the motion start acceleration range of a transport facility which accelerates at a certain speed within a predetermined range at motion start time;
acceleration continuation time storage means for storing the acceleration continuation time to determine whether the transport facility has begun to move;
acceleration range judging means for determining whether the acceleration detected by the acceleration sensor is within the motion start time acceleration range;
acceleration continuation judging means for determining whether the acceleration detected by the acceleration sensor is within the motion start time acceleration range and whether the duration thereof is longer than the acceleration continuation time;
transport facility motion start judging means for determining that the transport facility has begun to move when the acceleration detected by the acceleration sensor is within the motion start time acceleration range and the duration thereof is longer than the acceleration continuation time;
distance traveled calculating means for calculating, upon detection that the transport facility has begun to move, the distance traveled by transport facility based on the acceleration detected by the acceleration sensor;
route information storage means for storing route information consisting of information pertaining to either the distance between respective stations of the transport facility or information on the position of stations, and station identification information for identifying the respective stations;
entraining station storage means for storing the station identification information in respect of the entraining station of the transport facility; and
announcement device control means which controls an announcement unit for announcing station guidance to a user of the portable guide device based on the station identification information in respect of the entraining station, the route information and the distance traveled by the transport facility.

Abstract
A portable guide device is characterized by comprising a transport facility start judgment means for judging that a transport facility has begun to move if a period where an acceleration detected by an acceleration sensor (SN3) is included continuously in an acceleration range at the time of starting movement is not shorter than the acceleration continuation time; a distance calculation means for calculating the moving distance of the transport facility according to an acceleration detected by the acceleration sensor (SN3) when start of movement of the transport facility is detected; a route information storage means (KC6A) for storing route information including information on a distance between stations of the transport facility and station identifying information for identifying each station; and an announcement device control means (KC1) for controlling an announcement unit (11) which announces guidance of a station to a user of the portable guide device according to the station identification information on an entraining station, route information, and the moving distance.
