摘要： 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.

摘要： When a reset operation or the driving by a correction drive pulse P2 is performed, a stepping motor is driven by a plurality of main drive pulses P0 for initial setting stored in a storage circuit and the stepping motor is rotary driven by a correction drive pulse P2 following the respective main drive pulses P0, so that the main drive pulses P0 with energy as large as or larger than energy by which it is determined to maintain the pulse rank are used as main drive pulses P1 during normal correction drive. It thus becomes possible to perform driving by a main drive pulse suitable for the stepping motor in consideration of a characteristic variation of the stepping motor.

摘要： 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.

摘要： A stepping motor control circuit and an analogue electronic timepiece can optimize a rank change operation of a main drive pulse by properly determining an available driving force thus realizing the reduction of the power consumption. A detection interval in which a rotation state of a stepping motor is detected is divided into a first interval immediately after driving with a main drive pulse, a second interval which comes after the first interval, and a third interval which comes after the second interval, and a rotation state is detected. A control circuit looks up an interval table which makes respective main drive pulses stored in the control circuit and a length of the second interval, sets the second interval which corresponds to energy of the present main drive pulse. A detection interval determination circuit determines the interval or the intervals in which an induction signal which exceeds a reference threshold voltage is generated. The control circuit performs a pulse control of the main drive pulse based on the determination.
