ABSTRACT:
A rotary manipulation type input device obtains a specified output by detecting intensity changes of magnetic field due to rotation of an operating element by a detecting element disposed on a substrate beneath a base, using a ring-shaped magnet disposed at the lower side of the operating element disposed rotatably on the base. By rotary manipulation of the operating element, an attractive and repulsive force is generated between the ring-shaped magnetic and the magnetic disposed on the base, so that an operation contact click-feeling is obtained, and therefore the rotary click-feeling and signal output can be synchronized easily, and deterioration of rotary click-feeling is very rare.
