When (afterwards claiming signal magnetic field) in the magnetic field that antenna assembly 42 is placed standard time radio wave, this signal magnetic field acts on as following antenna assembly 42.Have, standard time radio wave is the long wave with several km wavelength again, and this magnetic field can be regarded as the big or small constant parallel magnetic field of any position magnetic-field component in the size range of antenna assembly 42.
When making the direction in the axis of coil 68 and signal magnetic field place magnetic 66 abreast in signal magnetic field, the magnetic flux that signal magnetic field is produced (hereinafter referred to as " signal magnetic flux ") concentrates on the magnetic 66 higher than surrounding space permeability.Its result, signal magnetic flux and coil 68 be closed to intersect (Lock friendships), on coil 68, according to Lenz's law, generates the such induced electromotive force V of generation magnetic flux to the direction of the signal magnetic flux change of the inside that hinders coil 68.And signal magnetic field is AC magnetic field, and the size and Orientation cyclic variation of signal magnetic flux, so induced electromotive force V becomes AC electromotive force.Its result, also the time along with signal magnetic flux changes and the periodically variable AC magnetic field of size and Orientation of generation magnetic flux on the magnetic 66.

In addition, if a pair of paper tinsel body 80 is set, then signal magnetic flux becomes in the lamination core components and is easier to flow, so the effective permeability of magnetic 66 rises the resonance frequency step-down.This will rise by effective permeability inductance L is increased.
F=1/2II (LC) 1/2 (formula 1)
Shown in (formula 1), resonance frequency f diminishes when inductance L increases.
Shown in Fig. 4 A and Fig. 4 B, the inner peripheral surface along spatial accommodation 14 disposes antenna assembly 42 12 positions in the spatial accommodation 14 of shell 20.And the non-coiling of a pair of coil portion 72 at two ends places that is positioned the length direction of magnetic 66 extends along spatial accommodation 14 inner peripheral surfaces.Therefore, antenna assembly 42 can dispose near the inner peripheral surface of spatial accommodation 14 12 positions in the spatial accommodation 14 of shell 20 as much as possible.Have, a pair of paper tinsel body 80 is attached to the outer surface of the lid 78b of core shell 78 again, when the inner peripheral surface of spatial accommodation 14 extends, extends along decorative panel 45 inner surfaces of the opening 16 of the spatial accommodation 14 of shell 20.Therefore, antenna assembly 42 shared volumes are little in the spatial accommodation 14, the dead angle along the inner peripheral surface in the spatial accommodation 14 can be used for holding of antenna assembly 42, and the degree of depth of spatial accommodation 14 also can reduce.In addition, antenna assembly 42 can with the spatial accommodation 14 that is disposed at metal shell 20 in irrespectively receive the time reference signal that is mapped in the spatial accommodation 14 well through opening 16 efficient of spatial accommodation 14.
