Abstract

An electronic timepiece enables a simple construction, and an electronic device has the electronic timepiece. A wristwatch 1 has a button A 6; a mode setting unit 32 that sets the operating mode of the wristwatch 1 based on an input operation of the button A 6. Based on the continuous input time that the button A 6 is operated continuously, the mode setting unit 32 changes the operating mode between a timekeeping mode that receives satellite signals from one or more GPS satellites and adjusts the internal time information based on time information contained in a received satellite signal; and a positioning mode that receives satellite signals from three or more GPS satellites and adjusts the internal time information based on time information and positioning information contained in the received satellite signals.

Claims

1. An electronic timepiece comprises:

an external operating member;

a mode setting unit that sets an operating mode of the timepiece based on an input operation of the external operating member;

a reception unit that receives a satellite signal transmitted from a positioning information satellite;

a reception control unit that controls operation of the reception unit and receives the satellite signal based on the operating mode;

a time adjustment unit that adjusts an internal time information based on the satellite signal received by the reception unit; and

an operation mode display unit that displays the operation mode being executed;

wherein the mode setting unit sets the operating mode to

a first mode that receives a satellite signal from one or more positioning information satellites and adjusts the internal time information based on time information contained in the received satellite signal, when a continuous input time for which the external operating member is operated continuously is greater than a first time and less than or equal to a second time, and

a second mode that receives satellite signals from three or more positioning information satellites and adjusts the internal time information based on time information and positioning information contained in the received satellite signals, when the continuous input time is greater than the second time, the second time being greater than the first time; and

wherein the operation mode display unit displays that the first mode is being executed when the external operating member is operated for at least the fist time and changes to display that the second mode is being executed when the external operating member is operated for at least the second time.

2. The electronic timepiece described in claim 1, wherein:

when the operating mode set by the mode setting unit is the second mode, the time adjustment unit calculates a standard time at the current location of the electronic timepiece and sets the internal time information based on the time information and positioning information contained in the satellite signals.

3. The electronic timepiece described in claim 1, further comprising:

a reception result storage unit that stores a reception result indicating whether or not satellite signal reception by the reception unit succeeded;

a reception result display unit that displays the reception result; and

a result display control unit that causes the reception result display unit to display the reception result;

wherein the mode setting unit sets a third mode that causes displaying the reception result stored in the reception result storage unit based on the continuous input time as the operating mode, and

when the third mode is set as the operating mode, the result display control unit displays the reception result on the reception result display unit.

4. The electronic timepiece described in claim 3, wherein:

the continuous input time when the mode setting unit sets the third mode as the operating mode is shorter than the continuous input time when the mode setting unit sets the first mode or the second mode as the operating mode.

5. The electronic timepiece described in claim 1, further comprising:

an operating time display unit that displays the continuous input time.

6. An electronic device comprising the electronic timepiece described in claim 1.
