PROBLEM TO BE SOLVED: To reduce power consumption, while maintaining calculation accuracy of a moving shape.SOLUTION: A moving shape calculating unit 24 calculates a moving shape based on a result in which an absolute position detection unit 30 detects the absolute position of a terminal body 10; and a result in which a link information generation unit 22 generates a line segment (link), showing a linear traveling distance of the terminal body 10. Then, a detection control unit 21 for determining the detection timing of the absolute position detection unit 30 sets the timing at each prescribed time as a temporary detection timing; and when bending is not detected by the time the temporary detection timing arrives, after immediately prior to the detection timing, the detection control unit determines a timing, when bending is detected in the next time as a detection timing, and performs absolute position detection using the absolute position detection unit 30. |
