文字板面に、外から見えるような構造で使用するのが一
般的な手段となっている。2. Description of the Related Art Conventionally, a solar cell in a timepiece having a solar cell is generally used on the dial surface under the windshield so that it can be seen from the outside because it absorbs light to generate electricity. It has become a means.
【０００３】このような手段では、太陽電池が独特の濃
紫の色を有するために、時計としての外観的な調和をと
ろうとすると、文字板の色やデザインは大きな制約を受
けてしまう。With such a means, the solar cell has a unique deep purple color, so that the color and design of the dial plate are greatly restricted when the appearance is harmonized as a timepiece.
【０００４】そこで太陽電池の上に被覆部材を設けるこ
とが提案されている。この被覆部材を設けた時計を、図
５の断面図を用いて説明する。Therefore, it has been proposed to provide a covering member on the solar cell. A timepiece provided with this covering member will be described with reference to the sectional view of FIG.
【０００５】図５に示すように、透明ガラスからなる風
