Position pointing device and core body for position pointing device
First Claim
1. A position pointing device comprising:
- a core body;
a tubular casing provided, on one end in an axial direction thereof, with an opening via which one end in an axial direction of the core body is exposed to an exterior; and
a pressure detecting part which is provided inside the tubular casing and detects a pressure applied in the axial direction of the core body;
wherein the core body includes;
a leading end part formed of an elastic material,a pedestal part formed of a material which is different from the elastic material of the leading end part and is harder than the elastic material of the leading end part, the pedestal part being positioned adjacent to the leading end part in the axial direction of the core body, anda core body main body part positioned adjacent to the pedestal part in the axial direction of the core body, a thickness of the core body main body part being smaller than a thickness of the pedestal part in a direction orthogonal to the axial direction of the core body; and
the core body is housed in the casing in a state of being movable in the axial direction of the core body, such that the leading end part is exposed to the exterior via the opening of the casing and that a pressure exerted on the leading end part in the axial direction of the core body is transmitted to the pressure detecting part provided on an opposite side of the core body main body part from the pedestal part,wherein the core body is disposed in a relation to the casing such that the leading end part is exposed by wholly protruding through the opening to the exterior and that a side surface of the pedestal part faces a surface of the opening of the casing, the side surface of the pedestal part and the surface of the opening of the casing extending in a direction along the axial direction of the core body.

Abstract
A position pointing device includes a pressure detecting part which detects a pressure applied in an axial direction of a core body. The core body includes: a leading end part formed from an elastic material; a pedestal part which is formed from a material harder than the material of the leading end part and is joined to the leading end part; and a core body main body part which is joined to the pedestal part, is smaller than the pedestal part in thickness in a direction orthogonal to the axial direction, and is formed from a hard material. The core body is housed in a casing and is movable in the axial direction, such that the leading end part is exposed via an opening of the casing, and a pressure exerted on the leading end part in the axial direction is transmitted to the pressure detecting part.

17. A core body for a position pointing device comprising:
-
a leading end part formed from an elastic material; a pedestal part which is formed from a material harder than the material of the leading end part and is positioned adjacent to the leading end part in an axial direction of the core body; and a core body main body part which is positioned adjacent to the pedestal part in the axial direction of the core body and a thickness of the core body main part is smaller than a thickness of the pedestal part in a direction orthogonal to the axial direction of the core body, wherein the core body is housed in a tubular casing of the position pointing device in a state of being movable in the axial direction of the core body, such that the leading end part is exposed to an exterior via an opening provided at one end portion in an axial direction of the casing, and that a pressure exerted on the leading end part in the axial direction of the core body is transmitted to a pressure detecting part which is provided inside the tubular casing and detects a pressure applied in the axial direction of the core body, wherein the core body is disposed in a relation to the casing such that the leading end part is exposed by wholly protruding through the opening to the exterior and that a side surface of the pedestal part faces a surface of the opening of the casing, the side surface of the pedestal part and the surface of the opening of the casing extending in a direction along the axial direction of the core body. - View Dependent Claims (18, 19, 20, 21, 22)
