<P>PROBLEM TO BE SOLVED: To provide a radio-controlled watch capable of receiving a standard wave from a direction in a larger range. <P>SOLUTION: The axes of antennas 5A, 5B are arranged in a direction parallel to the tube axial direction of an exterior case 1. The driving coil 431A of a stepping motor 43A for a minute hand and the driving coil 431B of a stepping motor 43B for an hour hand are shared with the antennas 5C, 5D receiving the standard wave, and then are arranged in a direction perpendicular to the tube axial direction of an exterior case 1 and also in a mutually perpendicular direction with the driving coils 431A, 431B. The antennas 5A, 5B, 5C, 5D are respectively arranged along one direction from among three mutually perpendicular directions therewith, thereby one or a plurality of these antennas 5A, 5B, 5C, 5D can properly receive the standard wave. <P>COPYRIGHT: (C)2005,JPO&NCIPI |
