    摘要: The invention is intended to achieve detection of a source voltage without providing a voltage detection circuit and allow a drive stop while holding correct drive pulse information when the source voltage is lowered to a predetermined level or below. A detection segment for detecting the state of rotation of a stepping motor is divided into a plurality of segments and, when a pattern of an induced signal detected in the respective segments is a pattern which indicates that the voltage of a secondary battery is lowered to the predetermined voltage or below, the control circuit memorizes a polarity of the drive pulse used in the last driving in a polarity memory and stops the driving of the stepping motor. When the voltage of the secondary battery is restored to the predetermined voltage or higher, the driving is restarted by a main drive pulse having a polarity opposite from the polarity memorized in the polarity memory.

    摘要: The present invention aims to prevent a nonrotation state from being brought about even when a drive allowance is changed by variations in a stepping motor or the like. A pulse down counter circuit outputs pulse down control signal for subjecting main drive pulse to control pulse down when time is counted for a predetermined time period. When a detecting signal exceeding a reference threshold voltage detected by a rotation detecting circuit is detected at a first detection section at start of a rotation detecting time period, a control circuit resets the pulse down counter circuit. Thereby, a main drive pulse generating circuit is not subjected to control pulse down by the pulse down counter circuit, and therefore, it is prevented that the main drive pulse is subjected to pulse down unnecessarily.

    摘要: An electronic timepiece can reduce a burden imposed on a user who performs a manipulation for correcting the positional displacement of a pointer when a position of the pointer is displaced due to the demonstration of the pointer movement. The electronic timepiece includes: a pointer which is rotated in a first direction based on a manipulation signal corresponding to a manipulation from the outside; and a control part which performs the demonstration of the pointer movement in which the pointer is rotated in a second direction opposite to the first direction and the first direction, wherein the pointer is positioned at a position where a rotational angle in the first direction from a preset reference position is smaller than a rotational angle in a second direction from the reference position.

    摘要: The invention is intended to detect whether or not a stepping motor is rotated when being driven immediately after a pulse-down control accurately. A control unit drives the stepping motor with a first main drive pulse after the pulse-down control, and then drives the same with a correction drive pulse. A second detection circuit detects a state of rotation on the basis of a current flowing through the stepping motor when being driven with the correction drive pulse. The control circuit controls a drive pulse selection circuit so as to select the main drive pulse to be used for the next time on the basis of a result of detection of the second detection circuit. The drive pulse selection circuit rotates the stepping motor with the main drive pulse corresponding to a control signal.
