Patent ID: 7502013

Claim:
A pointing device, comprising: a base section; an operating section shiftably supported on said base section; a magnet carried on said operating section; a magneto-electro transducer carried on said base section at a location close to said magnet; and a switch mechanism carried on said base and adapted to be actuated by a pressing operation of said operating section; and wherein said operating section includes a holding part securely holding said magnet and shiftably supported on said base section, and an elastic part connected to said holding part and exerting an elastic force for returning said holding part to a home position in a shifting range, while accompanying a shifting operation of said holding part on said base section, said holding part and said elastic part being formed separately from and assembled to each other, wherein said elastic part is provided with a major portion surrounding substantially an entire circumference of said holding part a first connecting portion connected to said holding part at one end of said major portion and extending be laid over said holding part, and a second connecting portion connected to said base section at another end of said major portion, said first connecting portion and said second connecting portion being formed integrally with said major portion, said major portion exerting an even elastic biasing force irrespective of a shifting direction of said holding cart on said base section, wherein said base includes a circuit board carrying said switch mechanism on a first side of said circuit board and positioning said switch mechanism at a location beneath said operating section, and a cover member covering said second connecting portion of said elastic part, said cover member being provided with an annular end wall defining a center opening and securely holding said second connecting portion at said end wall, wherein said magneto-electro transducer is mounted on a second side of said circuit board, opposite to said first side, said circuit board interposing between and separating said magnet and said magneto-electro transducer, and wherein a plurality of magneto-electro transducers are mounted on said second side of said circuit board at regular intervals in a circumferential direction about a center axis defining said home position.
