发明名称 Electronic timepiece with radio communication function
摘要 A photoelectric generating means ( 6 ) is disposed proximally to the surface of the dial ( 21 ) on the back cover ( 3 ) side, and the dial ( 21 ) is made of a magnetic, optically transparent material. The support substrate ( 62 ) of the photoelectric generating means ( 6 ) is a nonmagnetic material, and the antenna ( 5 ) is located proximally to the surface of the support substrate ( 62 ) on the back cover ( 3 ) side. Because the support substrate ( 62 ) is a nonmagnetic material, external RF signals can pass through the dial ( 21 ) and photoelectric generating means ( 6 ) to the coil ( 52 ) of the antenna ( 5 ), and signals can thus be received by the antenna ( 5 ). Because the antenna ( 5 ) can be contained inside the case member ( 1 ), the appearance can be improved.
