Pointing device
First Claim
1. A portable information apparatus, comprising:
- a pointing device comprising;
a base section;
an operating section shiftably supported on said base section;
a magnet carried on said operating section; and
a magneto-electro transducer carried on said base section at a location close to said magnet; and
a housing structure incorporating therein said pointing device;
wherein said operating section of said pointing device 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, andwherein 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 to be laid over said holding part, and a second connecting portion 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 part on said base section;
wherein said base section of said pointing device includes a part interposing between and separating said magnet and said magneto-electro transducer;
wherein said housing structure includes an opening, through which said holding part of said operating section shiftably penetrates, a recessed portion formed at a location surrounding said opening and depressed toward said base section, and a portion adjacent to said recessed portion and securely holding said second connecting portion of said elastic part.

Abstract
A pointing device including a base section, an operating section shiftably supported on the base section, a magnet carried on one of the base section and the operating section, and a magneto-electro transducer carried on the other of the base section and the operating section at a location close to the magnet. The operating section includes a first part securely holding one of the magnet and the magneto-electro transducer and supported on the base section shiftably in a desired horizontal direction relative to the base section, and a second part connected to the first part and elastically biasing the first part toward a home position in a horizontal shifting range during a period when the first part is horizontally shifted along the base section. The second part of the operating section is provided integrally with a major portion substantially surrounding an entire circumference of the first part, a first connecting portion connected to the first part at one end of the major portion and a second connecting portion connected to the base section at another end of the major portion; the major portion exerting an even elastic biasing force irrespective of a shifting direction of the first part on the base section.
