Title:
電子時計、および電子時計の制御方法
Document Type and Number:
Japanese Patent JP6950579
Kind Code:
B2
Abstract:
To provide an analog electronic clock that makes it possible to visually indicate a gradient between two points different from each other by inclination of a pointer.SOLUTION: An electronic clock calculates a gradient θ from a measurement start point to a current position as two different points with respect to a horizontal plane perpendicular to a gravity direction. A numerical display short needle 33 shows the gradient θ calculated by an angle α defined by a virtual straight line L1 which is in parallel to a direction connecting a scale member at a 9 o' clock position and a scale member at a 3 o' clock position and a numerical display long needle 33.SELECTED DRAWING: Figure 7
