Pointing device
First Claim
1. A pointing device, comprising:
- a base section;
an operating section arranged shiftably in a desired direction relative to said base section;
a signal generating part for detecting a relative displacement between said base section and said operating section to generate an analogue signal;
a switch mechanism capable of being actuated by a relative motion between said base section and said operating section in a direction different from said relative displacement to generate a signal; and
a processing part for processing said analogue signal generated from said pointing device and said signal generated from said switch mechanism as input data; and
wherein said processing part suspends processing said analogue signal generated from said pointing device during a period when said switch mechanism is actuated, even if said relative displacement is detected,wherein said pointing device includes a magnet carried on said operating section and a magneto-electro transducer carried on said base section at a location close to said magnet,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 part on said base section, andwherein said base includes a circuit board carrying said switch mechanism on and positioning said switch mechanism at a location beneath said operating section, said circuit board interposing between and separating said magnet and said magneto-electro transducer, 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.

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.
