    Abstract: An electronic timepiece includes a solar power source, a voltage stabilizer circuit that generates a constant voltage by using power supplied from the solar power source, and a control circuit that clocks the time by driving a rotating body at first hand operation speed and at second hand operation speed which is faster than the first hand operation speed. The control circuit selects a voltage of the solar power source so as to drive the rotating body in a case of the first hand operation speed, and selects at least any one voltage of the constant voltage and the voltage of the solar power source so as to drive the rotating body in a case of the second hand operation speed.

    Abstract: An electronic device includes at least an acquisition unit, an input unit, a time correction amount calculation unit, and a transmitting unit. A timepiece includes at least a receiving unit, a power storage unit, a drive unit, and a control unit. The input unit receives an input of the time displayed by the display unit of the timepiece. The time correction amount calculation unit calculates a time correction amount for correcting the time of the timepiece from a difference between the time, the input of which is received by the input unit and the current time acquired by the acquisition unit. The transmitting unit transmits the time correction amount to the timepiece by using light. The receiving unit receives the time correction amount. The power storage unit stores electricity by using power converted from the light. The drive unit drives the indicating hand. The control unit corrects the time displayed by the indicating hand, based on the time correction amount received by the receiving unit. The control unit controls a power storage period in the power storage unit and a receiving period in the receiving unit so as to receive the time correction amount in the receiving period.

    Abstract: A heartbeat measuring device has a measurement unit that measures a heart rate of a user, and an information storage unit that stores unique information regarding a heart rate unique to the user or information regarding a detected heartbeat of the user. A determination unit determines whether or not a heartbeat measurement state of the user is normal on the basis of the unique information or the information regarding a heartbeat stored in the information storage unit. An abnormality detection unit detects an abnormality corresponding to poor mounting of the heartbeat measuring device or interference due to external noise on the basis of a heart rate measured by the measurement unit. A notification unit performs a notification when the abnormality is detected by the abnormality detection unit. The notification unit changes information to be notified on the basis of a detection result by the abnormality detection unit.

    Abstract: An object is to provide a pointer driving motor unit which can easily control driving of a pointer of a time piece by a stepping motor, a multifunctional electronic device, and a control method of a pointer driving motor unit. A pointer driving motor unit includes: a supporting body; a stepping motor which rotates a pointer that is supported to be rotatable with respect to the supporting body; a plurality of input portions which include a first input portion into which a first instruction signal is input from a main control portion, and a second input portion into which a second instruction signal is input from the main control portion; and a control portion which is provided in the supporting body, outputs a first driving signal that drives the pointer by a first operation to the stepping motor based on a result of comparing the first instruction signal and a predetermined threshold value with each other, and outputs a second driving signal that drives the pointer by a second operation to the stepping motor based on a result of comparing the second instruction signal and a predetermined threshold value with each other.
