发明名称 Electronic timepiece
摘要 An electronic timepiece can adjust the input terminal and suppress power consumption. An electronic timepiece has: a reception unit 8 that receives a satellite signal containing time information from a positioning information satellite; a power supply unit 4 having a battery that supplies drive power; a remaining capacity detection unit 5 that measures the remaining battery capacity; and a control unit 9 that controls satellite signal reception by the reception unit 8. The control unit 9 includes a timekeeping unit 91 that keeps time, a time adjustment unit 99 that adjusts the time kept by the timekeeping unit 91 based on the satellite signal received by the reception unit 8, and a prohibition period setting unit 93 that sets a prohibition period in which receiving a satellite signal is prohibited based on the remaining battery capacity measured by the remaining capacity detection unit 5.

主权项 1. An electronic timepiece comprising: a reception unit that receives a satellite signal containing time information from a positioning information satellite; a power supply unit having a battery that supplies drive power; a remaining capacity detection unit that measures the remaining battery capacity; and a control unit that controls satellite signal reception by the reception unit, and includes a timekeeping unit that keeps time,a time adjustment unit that adjusts the time kept by the timekeeping unit based on the satellite signal received by the reception unit, anda prohibition period setting unit that sets a first prohibition period in which receiving a satellite signal is prohibited when the remaining battery capacity, as measured by the remaining capacity detection unit, is greater than or equal to a threshold, and sets a second prohibition period in which receiving a satellite signal is prohibited when the remaining battery capacity, as measured by the remaining capacity detection unit, is less than the threshold, the second prohibition period being longer than the first prohibition period.
