Input device and electronic apparatus using same

An input device comprising:

• a housing comprising an operation hole formed therein;
• an operation member supported in a slidably moving manner in multi-directions within the operation hole, and
• at least two magnetic sensors, arranged at a periphery of the operation member, for detecting change in magnetic property by displacement of the operation member, wherein
• the operation member includes a holder having a circular ring-shaped magnet incorporated in a fit-in hole and a central push button having a disc plate made of magnetic material integrated at a lower surface,
• the central push button and the disc plate are integrally molded with same magnet material and having same polarity as the circular ring-shaped magnet, and
• the central push button is fitted in the circular ring-shaped magnet to position-regulate the operation member by a repulsive force of the magnet.

An input device comprising:

• a cover plate constituting a housing, comprising an operation hole formed therein,
• an operation member supported in a slidably moving manner in multi-directions within the operation hole, and
• at least two magnetic sensors, arranged at a periphery of the operation member, for detecting displacement of the operation member with change in magnetic property, wherein
• the operation member has a circular ring-shaped magnet of a separate body integrally formed at an outer peripheral surface of the central push button,
• the central push button is operably exposed from the operation hole of the cover plate made of magnetic material, and
• the circular ring-shaped magnet is adsorbed, in a separable manner, to an inner side of the cover plate.
