After judging that it was stopped, the stop judgment was repeated for the first time.
As a result , when the data input means is judged to be continuously stopped and the data input means is not operated in the first time, a first control signal for stopping the power supply of the selected portion is output, and the continuation is continued.
Then, as a result of repeating the stop determination for a predetermined second time which is longer than the first time, it is continuously stopped.
Determination and, and a power supply control signal generating means for outputting a second control signal for stopping the power supply to the positioning device when the data input means is not operated in the second time, the power supply
A positioning device comprising: a power supply unit that controls power to each unit based on a control signal from the control signal generation unit . 5. The positioning means moves by a signal from a satellite.
The positioning device according to claim 1, 2 or 3, or 4, which is configured to obtain the current position of the body . 6. The positioning according to claim 1, claim 2 or claim 3 or claim 4, comprising map information storing means for storing map information and map information searching means for searching a map from the map information storing means. apparatus.
