Abstract
An antenna receives a radio wave transmitted from a GPS satellite. A wireless processing unit extracts positioning information from a signal of the radio wave received by the antenna. The positioning unit performs positioning on the basis of the positioning information extracted by the wireless processing unit. A transformer circuit includes a switching element and transforms supplied power to a predetermined voltage. A switching unit switches the transformer circuit to a stop state during an extraction period in which the positioning information is extracted by the wireless processing unit.
