Abstract: An invention allows a stepping motor to be reliably driven to rotate when initializing the driving and allows power consumption of the stepping motor to be reduced. The controller, when initializing the driving (for example, replacing a battery), controls a main drive pulse generator to drive a stepping motor using a main drive pulse having a maximum energy and sets the generation cycle of a pulse down control signal of a pulse down counter for pulsing down the main drive pulse to a first cycle to drive the stepping motor, and when pulsing down the main drive pulse to that having a predetermined energy, changes the generation cycle of the pulse down control signal of the pulse down counter to a second cycle.

Abstract: When a stepping motor is driven to rotate by a main driving pulse, if an induced signal exceeding a reference threshold voltage is detected only in a third segment, a pulse down operation is performed, and the main driving pulse is not changed when the same is detected in at least a first and the third segments. When it is detected only in a second and the third segments, a rank-up is performed without performing the driving by a correction drive pulse and, when it is not detected in at least the third segment, the rank up operation is performed after the driving by the correction driving pulse.

Abstract: The present invention aims to prevent a main drive pulse from being moved to a rank having a potential to cause a non-rotating state. A detection segment for detecting a rotating state of a stepping motor is divided into a first segment immediately after the drive with a main drive pulse, a second segment, and a third segment and, when the stepping motor is rotated by the main drive pulse, the main drive pulse is not changed when a detection signal exceeding a reference threshold voltage is detected at least in the first and second segments. When it is detected only in the first and third segments, or detected only in the third segment, the rank is moved upward and, when it is not detected in any segment, or detected only in the first segment, the rank is moved upward after the drive with a corrective drive pulse. When it is detected only in the second segment or detected only in the second and third segments, the rank is moved downward.

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.

Abstract: Disclosed is a chronograph timepiece in which it is possible to prevent the battery reliability service life time from being exceeded even when the period of time that the chronograph function is used is short, making it possible to prevent failure generation in the chronograph timepiece due to liquid leakage. A 24-hour counter down-counts a period of time that has elapsed starting from 24 hours, and a chronograph counter down-counts the period of time that chronograph measurement operation is performed from a predetermined time; when the count values of the 24-hour counter and the chronograph counter become equal to each other, a processing unit consumes a battery for the residual period of time of the two counters by a battery power consuming unit.

Abstract: Disclosed is a chronograph timepiece in which it is possible to prevent the chronograph drive timing and the magnetic field detection timing from overlapping each other to unnecessarily effect driving with correction drive pulses. A processing unit controls drive circuits so as to drive a time indication motor and a chronograph indication motor with a predetermined timing based respectively on timekeeping information obtained and chronograph measurement information obtained, and effects control such that a magnetic field detecting unit detects a magnetic field with a predetermined timing; when the drive timing for the chronograph indication motor and the magnetic field detection timing for the magnetic field detecting unit overlap each other, the processing unit changes the magnetic field detection timing for the magnetic field detecting unit so that the drive timing for the chronograph indication motor and the magnetic field detection timing for the magnetic field detecting unit may not overlap each other.

Abstract: When it is judged that a chronograph second counter and a chronograph minute counter have measured a maximum measurement time, a maximum measurement control unit controls a drive pulse generation circuit so as to drive and stop a motor such that chronograph hand stops at predetermined positions. When, in this state, a restarting operation is performed on a start/stop button, a normal chronograph measurement operation is restarted. At this time, a mechanical structure has been restored to a reset state, so that even at the time of restarting after the measurement of the maximum measurement time, the load at the starting operation is the same as that of the normal operation, thus generating no sense of incongruity.

Abstract: 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.
