Abstract
Official abstract text for this publication.
A thin electronic timepiece can receive satellite signals and standard time signals. An electronic timepiece has a planar antenna for receiving satellite signals, a bar antenna for receiving standard time signals, a time display unit with a plurality of hands, a plurality of motors for driving the hands, a battery, and a timepiece case. In a plan view of the electronic timepiece, the planar antenna, bar antenna, and battery are disposed to positions not mutually superimposed; the plural motors are disposed inside the timepiece case at positions not superimposed in plan view with the planar antenna and bar antenna; and at least one of the plural motors is disposed superimposed in plan view with the battery inside the timepiece case.
First claim
Opening claim text (preview).
What is claimed is: 1. An electronic timepiece comprising: a planar antenna for receiving satellite signals, a bar antenna for receiving standard time signals, a time display unit with a plurality of hands, a plurality of motors for driving the hands, a battery, and a timepiece case, wherein: the planar antenna, bar antenna, and battery are disposed to positions not mutually superimposed in plan view inside the timepiece case; the plural motors are disposed inside the timepiece case at positions not superimposed in plan view with the planar antenna and bar antenna; and at least one of the plural motors is disposed superimposed in plan view with the battery inside the timepiece case. 2. The electronic timepiece described in claim 1 , further comprising: a solar cell disposed inside the timepiece case, the electrode layer of the solar cell not superimposed in plan view with the planar antenna, and the electrode layer of the solar cell superimposed in plan view with the bar antenna. 3. The electronic timepiece described in claim 1 , further comprising: a first circuit board and a second circuit board inside the timepiece case; a control chip for controlling driving the motors, and a power control chip for controlling a power supply including the battery, being disposed to the first circuit board; and the planar antenna, bar antenna, a satellite signal receiver chip for controlling receiving satellite signals by the planar antenna, and a standard time signal receiver chip for controlling receiving standard time signals by the bar antenna, being disposed to the second circuit board. 4. An electronic timepiece described in claim 1 , wherein: a first magnetic shield and a second magnetic shield are disposed inside the timepiece case; the first magnetic shield and second magnetic shield being not superimposed in plan view with the planar antenna and bar antenna. 5. An electronic timepiece comprising: a planar antenna for receiving satellite signals, a bar antenna for receiving standard time signals, a time display unit with a plurality of pivots and hands attached to the pivots, a plurality of motors for driving the hands, a battery, and a timepiece case, wherein: the planar antenna, bar antenna, and battery are disposed to positions not mutually superimposed in plan view inside the timepiece case; the plural pivots are disposed inside the timepiece case at positions not superimposed in plan view with the planar antenna and bar antenna; and at least one of the plural pivots is disposed superimposed in plan view with the battery inside the timepiece case.
