| 发明名称 | Electronic timepiece | ||
| 摘要 | An electronic timepiece has a case of which at least part is conductive; a clock chip that keeps and displays time on a time display means; a receiver chip that receives a radio signal through a GPS antenna; a storage battery; a timekeeping voltage conversion unit that converts output voltage from the storage battery to drive voltage for the clock chip; and a receiver voltage conversion unit that converts output voltage from the storage battery to drive voltage for the receiver chip. The output terminal of the timekeeping voltage conversion unit is connected to the clock chip and the case, and the output terminal of the receiver voltage conversion unit is connected to the receiver chip. | ||
