发明名称 Antenna device and radio wave controlled timepiece
摘要 An antenna device includes an antenna for receiving a time information radio wave, and an antenna support member. In the antenna, a coil is wound around a center portion of a core. In the support member, a non-magnetic portion supports two magnetic portions independently and both end portions of the core of the antenna are magnetically coupled with the magnetic portions. A radio wave controlled timepiece includes a case in an inner space of which the antenna and the support member are installed as described above. In the inner space, a time counting unit, a time display unit connected to the time counting unit, and a time updating unit configured to update the time displayed on the display unit, based on the time information radio wave received by the antenna, are installed.
