Abstract

PURPOSE:To transfer external information to an electronic wrist watch efficiently without contacting, by forming its case by using a metallic material and by receiving an AC magnetic field within a prescribed range. CONSTITUTION:The case of an electronic wrist watch 1 is made of a metallic material and an external AC magnetic field of <=1MHz passed through a transmitting coil 3 is received by a receiving coil 2 efficiently. Therefore, external information is transferred efficiently without contacting to obtain the electronic wrist watch capable of desired control.
