    摘要: A voltage detection circuit detects a voltage of a secondary cell that powers a stepping motor. A rotation detection circuit detects a rotation state of the stepping motor, and a control unit selects a main driving pulse for driving the stepping motor based on the detected rotation state from plural kinds of driving pulses having different energies. An analog display unit announces that the voltage of the secondary cell becomes a predetermined reference voltage when the voltage detection circuit detects that the voltage of the secondary cell becomes the predetermined reference voltage. When the control unit selects a predetermined main driving pulse before the voltage detection circuit detects that the voltage of the secondary cell becomes a current reference voltage, the control unit sets the reference voltage to the predetermined reference voltage higher than the current reference voltage.

    摘要: Disclosed is a chronograph timepiece whose chronograph hands are electrically drive-controlled and mechanically zero-restoring-controlled, wherein it possible to perform a normal operation at the time of start operation and reset operation. After a mechanical control unit releases the setting of chronograph hands in response to the start operation of a start/stop button, a contact portion is placed in a start state, and an electrical control unit starts a time measurement operation to electrically hand-movement-drive the chronograph hands, and, after a contact portion is placed in a reset state in response to a reset operation of a reset button and the electrical control unit electrically resets the time measurement operation, the mechanical control unit mechanically zero-restores and sets the chronograph hands.

    摘要: A power generation unit generates electric power depending on light to be irradiated to a light receiving surface. An electricity storage unit stores the electric power generated by the power generation unit and outputs the stored electric power. A voltage detection unit detects a voltage of the electric power that is output from the electricity storage unit. A processing unit performs time measurement. A chronograph indicator points a time counted by the processing unit and is fixed by a mechanism while the time measurement is stopped. A second driving circuit drives the chronograph indicator by the use of the electric power that is output from the electricity storage unit. The processing unit drives the second driving circuit when the voltage of the electric power which is output from the electricity storage unit is equal to or greater than a predetermined threshold value.

    摘要: Disclosed is a chronograph timepiece in which it is possible to prevent a non-rotation state at the time of first driving when chronograph measuring operation is reset during motor drive and restarting is effected. When a resetting operation is performed on a reset button during the driving of a motor and a rotation detection circuit detects non-rotation, a drive control unit controls a drive pulse generation circuit such that the control is completed without reversing the polarity of a motor drive pulse output from the drive pulse generation circuit, and that the motor is driven by a drive pulse of the same polarity as that at the time of the previous resetting in response to a starting operation performed on a start/stop button, driving the motor by the drive pulse of the same polarity at the time of restarting after the resetting.
