    Abstract: Disclosed is a stepping motor including a rotor, a stator which includes a rotor accommodating hole, a pair of outer notches to determine positions of saturated magnetic fluxes and inner notches disposed on an inner periphery of the stator around the rotor accommodating hole, the inner notches determining stably stationary positions of the rotor, and a coil block configured by a coil wound around a coil core which is magnetically coupled to the stator, and the outer notches are disposed on an outer periphery of the stator on opposite sides of the rotor accommodating hole. And a line that connects narrowest portions between the outer notches and the rotor accommodating hole and extends through a center of the rotor accommodating hole shifts by a predetermined angle from a line that extends through the center of the rotor accommodating hole and is orthogonal to an extending direction of the stator.

    Abstract: In a timepiece 100 having an antenna 3 and motors 4, each motor 4 includes a stator 41, a coil 42 magnetically connected to the stator 41, and a rotor magnet 431 disposed in a receiving part 411 of the stator 41. With respect to each motor 4 disposed in a predetermined range from the antenna 3, an individual antimagnetic plate 5 which is a belt-like antimagnetic plate configured to have a width equal to or greater than the diameter of the rotor magnet 431 and cover a portion of the motor 4 including the rotor magnet 431 is disposed.

    Abstract: A high-speed rotating wheel rotates at high speed by a third stepper motor which meshes with a portion of teeth of a ratchet wheel. A transmission projection of the ratchet wheel moves within an elongated hole of a transmission wheel which rotates with the movement of the hour hand. The ratchet wheel rotates at high speed, and a display wheel rotates at high speed by the high speed rotation of the ratchet wheel via a feed wheel. When normally moving the hour hand, the ratchet wheel rotates with the transmitting wheel and the portion of teeth of the ratchet wheel is made to approach the high-speed rotating wheel. When the display of the display wheel changes, the high-speed rotating wheel meshes with the portion of teeth of the ratchet wheel and rotates the ratchet wheel at high-speed. Accordingly, the date display of the display wheel can be quickly changed.

    Abstract translation: 高速旋转轮通过与棘轮的齿的一部分啮合的第三步进马达高速旋转。 棘轮的传播突起在随着时针的移动而旋转的传动轮的长孔内移动。 棘轮以高速旋转，并且显示轮经由进给轮通过棘轮的高速旋转而高速旋转。 当正时移动时针时，棘轮与传动轮一起旋转，使棘轮的齿部接近高速旋转轮。 当显示轮的显示改变时，高速旋转轮与棘轮的齿的部分啮合并使棘轮高速旋转。 因此，可以快速地改变显示轮的日期显示。
