<p><P>PROBLEM TO BE SOLVED: To provide an inexpensive optical coupling detector usable as an impact sensor, and having long service life; and an electronic apparatus equipped with the optical coupling detector. <P>SOLUTION: This optical coupling detector includes: a light emitting element component 1 converting an electric signal to an optical signal; a light reception element component 2 arranged oppositely to the light emitting element component 1, and receiving an optical signal output from the light emitting element component 1 to convert it to an electric signal; a permanent magnet 4; and a light shading metallic mobile body 5 attracted to the permanent magnet 4 by magnetic force; and is structured such that the light shading metallic mobile body 5 is separated from the permanent magnet 4 when receiving impact from the outside, and moved to a position to shut off an optical path L between the light emitting element component 1 and the light reception element component 2. <P>COPYRIGHT: (C)2009,JPO&INPIT</p> |
