Description

This invention relates to a watch face and a clock. Patent Document 1 discloses a watch face in which a phosphorescent phosphor layer, which is a light-transmitting material, is formed on the back surface of a substrate made of transparent resin. This watch face is used as the watch face for a watch with a solar panel. Japanese Patent Application Publication No. 11-23739 This is a front view of the clock according to this embodiment.This is a cross-sectional view of the clock along the line A-A in Figure 1.This is an exploded perspective view showing the internal components of the watch.This is an exploded perspective view showing the configuration of the dial according to the first form.This is an enlarged cross-sectional view of region B in Figure 2.This is an enlarged cross-sectional view of the dial according to the second embodiment.This is an enlarged cross-sectional view of the dial according to the third embodiment.This is an enlarged cross-sectional view of the dial according to the fourth embodiment.This is an enlarged cross-sectional view of the dial according to the fifth embodiment.This is an enlarged cross-sectional view of the dial according to the sixth embodiment.This is an enlarged cross-sectional view of the dial according to the seventh form.This is a front view of the modified clock. Hereinafter, embodiments of the present invention will be described with reference to the drawings. In each drawing, different scales may be used for the dimensions of each component to make them easier to see. For the sake of explanation, the drawing shows three mutually orthogonal axes: the X, Y, and Z axes. The tip of the arrow indicating the axis direction is referred to as the "positive side," and the base end as the "negative side." The direction parallel to the X axis is referred to as the "X-axis direction," the direction parallel to the Y axis as the "Y-axis direction," and the direction parallel to the Z axis as the "Z-axis direction." In the drawing, the direction perpendicular to the surface 11 of the dial 1 is defined as the Z-axis direction. Viewing in the Z-axis direction is referred to as the "plan view." Furthermore, in each component of the clock 10, the surface on the positive side of the Z-axis direction is defined as the front surface or top surface, and the surface on the negative side of the Z-axis direction is defined as the back surface or bottom surface. 1. Embodiment 1 1.1. Clock The clock 10 according to this embodiment will be described below with reference to the drawings. Figure 1 is a front view of the clock 10 according to this embodiment. Figure 2 is a cross-sectional view of the clock 10 along the line A-A in Figure 1. Figure 3 is an exploded perspective view showing the internal configuration of the clock 10, and shows the positioning structure of the dial 1 and solar panel 9 of the clock 10. The watch 10 is a luminous type wristwatch in which the dial 1 has a luminous layer 5, and the luminous layer 5 absorbs sunlight and artificial light and emits light, thereby enhancing visibility in dark places. In this embodiment, the watch 10 further has a solar panel 9 and is equipped with a solar power generation function that stores energy using sunlight and fluorescent light, and a GPS automatic time correction function that automatically corrects the time by receiving satellite signals from GPS (Global Positioning System) satellites. While the clock 10 may not be equipped with either a solar power generation function or a GPS automatic time correction function, or both, it is preferable that the clock 10 be equipped with at least a solar power generation function. This is because the clock 10 in this embodiment is designed to prevent the dial 1 from appearing dark due to the influence of the solar panel 9's color. Details of the design modifications to the dial 1 will be explained in section 1.2 below. As shown in Figures 1 and 2, the watch 10 comprises an outer case 30, a cover glass 33, and a metal case back 34. The watch 10 is worn on the user's wrist by a band 18 connected to the outer case 30. On the side of the outer case 30, an operation button 13a is provided at the 2 o'clock position relative to the center of the dial 1, an operation button 13b is provided at the 4 o'clock position, and a crown 14 is provided at the 3 o'clock position. The outer case 30 is composed of a case 31 and a bezel 32, both made of metal. The case 31 has a cylindrical shape, and the bezel 32 is fitted onto the positive Z-direction side of the case 31. Inside the outer case 30, the following internal components are arranged: dial ring 3, dial 1, solar panel 9, calendar wheel 16, first magnetic shielding plate 160, base plate 100, circuit board 120, second magnetic shielding plate 170, circuit retainer 122, conductive spring section 123, secondary battery 130, drive mechanism 140, pointer shafts 24, 25, 26, and pointers 21, 22, 23. The pointer shafts 24, 25, and 26 are positioned at the center o
