    摘要: A stepping motor control circuit includes a rotation detection portion that detects a rotation condition of a stepping motor, and a control portion that drives and controls the stepping motor by a correction drive pulse P2 having larger drive energy than one of any one of a plurality of main drive pulses P1 each having different drive energy and the respective main drive pulses P1 depending on a detection result of the rotation detection portion. The control portion drives the stepping motor by switching to a fixed drive pulse having drive energy not smaller than drive energy of a main drive pulse P1nmax having maximum drive energy in a case where there is no drive allowance when the stepping motor is driven by the main drive pulse P1nmax having the maximum drive energy. The stepping motor is thus rotary driven normally even in a DC magnetic field.

    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: 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.

    摘要: For a chronograph timepiece that chronograph hands are mechanically reset to zero and electrically driven, the chronograph hands are prevented from being electrically driven while being mechanically locked. A chronograph timepiece that is mechanically reset to zero includes a chronograph motor for driving a chronograph hand, a drive unit configured to drive the chronograph motor according a time measurement operation in response to a starting operation by an operating section, and a control unit configured to control the drive unit. The control unit has a rotation detecting circuit for detecting a rotation status of the chronograph motor. When the rotation detecting circuit detects that the chronograph motor is not rotated after the chronograph motor has been rotated a predetermined time period, driving the chronograph motor by the drive unit is stopped for resetting the time measurement operation.
