    摘要： A display device includes independently driven common and segment terminals. The common and segment terminals are connected to display components divided into display blocks that are turned ON to perform a display function and are turned OFF so as to not perform the display function. A first driver drives the common terminals using a scanning signal of a predetermined period and a second driver drives the segment terminals using a segment signal synchronized with the scanning signal to correspond to a display signal, so that the display components perform a display corresponding to the display signal. The first driver separates the common terminals into common terminal blocks and drives the common terminals. The first and second drivers perform the driving so that the common and segment terminals which are connected to display blocks that are turned OFF are not supplied with a turn-off signal and are maintained at ground potential.

    摘要： 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.

    摘要： A stepping motor control circuit includes a rotation detecting means which detects an induced signal generated by rotation of a rotor of a stepping motor, and detects a rotation state of the stepping motor according to whether the induced signal exceeds a predetermined reference threshold voltage in a predetermined detection section, and a control means which controls driving of the stepping motor by using any one of a plurality of main driving pulses having energies different from each other or a correction driving pulse with energy higher than energy of each main driving pulse according to a detection result of the rotation detecting means. The detection section is divided into a first section immediately after driving by the main driving pulse, a second section after the first section and a third section after the second section. During the driving of the stepping motor by the main driving pulse, when the rotation detecting means has detected an induced signal exceeding a first reference threshold voltage in the first section and the second section, if an induced signal exceeding a second reference threshold voltage lower than the first reference threshold voltage is not detected in the third section, the control means drives the stepping motor by using the correction driving pulse.

    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.

    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.
