Abstract: An electronic watch includes a pointer; a stepping motor including a coil and configured to drive the pointer; a driving circuit configured to drive the stepping motor; an A/D converter configured to detect electromotive force generated in the coil due to an impact; and a CPU configured to control driving of the driving circuit. The CPU determines a direction in which the pointer is likely to be shifted, based on the electromotive force detected by the A/D converter, determines whether the pointer is shifted due to the impact, and upon determining that the pointer is shifted, corrects a position of the pointer in accordance with the direction in which the pointer is likely to be shifted.

Abstract: A stepping motor includes: a rotor; and a stator including an opening accommodating the rotor, a first side yoke extending from the opening in a first direction, a second side yoke extending from the opening in a second direction that is a direction opposite to the first direction, and one or a plurality of coils magnetically coupled to the first side yoke or the second side yoke. Assuming a direction orthogonal to the first direction and the second direction is defined as a third direction, a first recess is formed in an outer circumference of the stator at a position rotated from the third direction toward the second direction by a prescribed first angle and a second recess that determines a stable resting position of the rotor is formed at a position rotated from the second direction toward the third direction by a prescribed second angle.

Abstract: A solar panel, above which a pointer mounted on a pointer shaft inserted in a through hole in a center portion of the solar panel moves, includes a plurality of solar cells arranged in a substantially circular shape, and these solar cells have been divisionally formed into a substantially spiral shape so that the pointer is positioned over two of the plurality of solar cells. Accordingly, the pointer can always be positioned over two of the plurality of solar cells, and therefore a decrease of light-receiving area due to the pointer can be distributed between the two solar cells. As a result, a decrease in the output current of the plurality of solar cells over which the pointer is positioned can be suppressed, and the output current of the entire plurality of solar cells can be improved.
Abstract translation: 太阳能电池板，其上安装在插入太阳能电池板中心部分的通孔中的指针轴上的指针移动，包括布置成大致圆形形状的多个太阳能电池，并且这些太阳能电池分开形成 大致螺旋形状，使得指示器位于多个太阳能电池中的两个上。 因此，指针总是可以位于多个太阳能电池中的两个上，因此可以在两个太阳能电池之间分配由于指示器引起的光接收面积的减少。 结果，可以抑制指示器所在的多个太阳能电池的输出电流的降低，并且可以提高整个多个太阳能电池的输出电流。
