1. A positioning device comprising:
- a device body;
a direction change detecting section that detects whether a traveling direction of the device body has been changed based on a detection of an azimuth with respect to reference axes preset in the device body; and
an absolute position acquiring section that acquires an absolute position of the device body at a timing based on a change of the moving direction of the device body as detected by the direction change detecting section.

Abstract
A positioning device includes: a device body; a direction change detecting section that detects whether a traveling direction of the device body has been changed based on a detection of an azimuth with respect to reference axes preset in the device body; and an absolute position acquiring section that acquires an absolute position of the device body at a timing based on a change of the moving direction of the device body as detected by the direction change detecting section.

4. A positioning device comprising:
-
a device body; an azimuth acquiring section that acquires an azimuth based on reference axes preset in the device body; a moving distance acquiring section that acquires a moving distance of the device main body; a direction change detecting section that detects whether a moving direction of the device body has been changed on the basis of a result of acquisition executed using the azimuth acquiring section; an absolute position acquiring section that acquires absolute position information of the device body at a timing determined on the basis of whether the moving direction of the device body has been changed; and a moving route acquiring section that specifies a moving route of the device body from the absolute position information of the device body acquired using the absolute position acquiring section and the moving distance of the device body acquired using the moving distance acquiring section. - View Dependent Claims (5, 6, 7, 8)

9. A computer-readable medium for recording a program allowing a computer to execute:
-
acquiring an azimuth based on reference axes preset in a device body; acquiring a moving distance of the device body; detecting whether a moving direction of the device body has been changed on the basis of a result of the acquiring the azimuth; acquiring absolute position information of the device body at a timing determined on the basis of information as to whether the moving direction of the device body has been changed from the detecting; and specifying a moving route of the device body from the acquired absolute position information of the device body and the acquired moving distance of the device body.
