Abstract
Official abstract text for this publication.
Provided is an electronic timepiece including: an antenna configured to receive a standard radio wave, a pointer, a motor configured to drive the pointer, a circuit board having a front surface mounted with a semiconductor device including an active region, and a magnetic shield plate disposed at a back surface side of the circuit board, the magnetic shield plate having a shape that overlaps at least a portion of the motor and does not overlap the active region of the semiconductor device in plan view as viewed in a direction orthogonal to the front surface of the circuit board.
First claim
Opening claim text (preview).
What is claimed is: 1 . An electronic timepiece comprising: an antenna configured to receive a standard radio wave; a pointer; a motor configured to drive the pointer; a circuit board having a front surface mounted with a semiconductor device including an active region; and a magnetic shield plate disposed at a back surface side of the circuit board, the magnetic shield plate having a shape that overlaps at least a portion of the motor and does not overlap the active region of the semiconductor device in plan view as viewed in a direction orthogonal to the front surface of the circuit board. 2 . The electronic timepiece according to claim 1 , wherein the active region of the semiconductor device includes an oscillation circuit and a frequency dividing circuit. 3 . The electronic timepiece according to claim 1 , wherein the active region includes neither an input-output unit nor an electrostatic protective circuit. 4 . The electronic timepiece according to claim 1 , wherein the front surface of the circuit board is mounted with a receiving semiconductor device configured to control reception processing performed by the antenna, and the magnetic shield plate has a shape that does not overlap an active region of the receiving semiconductor device as viewed in plan view. 5 . The electronic timepiece according to claim 1 , wherein the antenna includes an antenna coil, a plurality of the motors are provided, and a distance between at least one motor out of the plurality of the motors and the antenna coil is longer than a distance between the semiconductor device and the antenna coil.
