Description

このような目的は下記の本発明により達成される。
本発明の時計は、窓部を有する文字板と、
前記文字板の背面側に設置された複数の太陽電池素子を備える太陽電池と、
指針が取り付けられ、前記窓部を貫通する軸とを有し、
前記窓部は、前記文字板の他の部位よりも光の透過性の高い部位であり、
前記軸は、前記太陽電池素子に設けられた孔部に挿通されたものであり、
前記窓部から前記太陽電池素子の外周部が視認されないように、前記太陽電池が配置されていることを特徴とする。
これにより、文字板の窓部に入射した光を、太陽電池による発電に効率よく利用することができるとともに、美的外観に優れた時計を提供することができる。 Such an object is achieved by the present invention described below.
The timepiece of the present invention includes a dial having a window ,
A solar cell comprising a plurality of solar cell elements installed on the back side of the dial,
A pointer is attached and has a shaft passing through the window;
The window portion is a portion having a higher light transmittance than other portions of the dial,
The shaft is inserted through a hole provided in the solar cell element,
The solar cell is arranged so that an outer peripheral portion of the solar cell element is not visually recognized from the window portion.
Thereby, the light incident on the window portion of the dial can be efficiently used for power generation by the solar cell, and a watch having an excellent aesthetic appearance can be provided.
