POSITION INDICATOR
First Claim
1. A position indicator, comprising:
- a cylindrical chassis;
a core body, which is disposed within the cylindrical chassis such that a tip thereof protrudes from a distal opening end of the cylindrical chassis;
a printed wiring board, which is disposed within the cylindrical chassis and which is provided with a circuit element to detect a pressing pressure applied to the tip of the core body;
one or more pressure-sensitive components configured to detect a displacement of the core body, in an axial direction of the cylindrical chassis, corresponding to the pressing pressure applied to the tip; and
a holder, which is accommodated within a hollow portion of the cylindrical chassis with its longitudinal direction being aligned with the axial direction of the cylindrical chassis,wherein the holder includes;
a core body engaging portion configured to hold the core body and to regulate movement of the core body in a direction toward the tip;
a component disposing portion, which defines an opening portion that opens in a direction perpendicular to the axial direction and in which the one or more pressure-sensitive components are arranged in the axial direction so as to receive the pressing pressure applied to the core body; and
a printed wiring board mounting portion, which is engaged with the printed wiring board to mount the printed wiring board thereon with a longitudinal direction of the printed wiring board being aligned with the axial direction, andwherein the holder that secures therein the core body, the printed wiring board, and the one or more pressure-sensitive components is accommodated in the cylindrical chassis, whereby the pressing pressure applied to the core body is received by the holder to prevent the pressing pressure from being directly applied to the cylindrical chassis.

Abstract
A position indicator is provided, which includes a chassis that accommodates a holder therein, wherein the holder in turn accommodates various elements therein. The holder includes a core body engaging portion configured to hold a core body, a component disposing portion in which one or more pressure-sensitive components are disposed in an axial direction so as to receive a pressing pressure applied to the core body, and a printed wiring board mounting portion for being engaged with and mounting a printed wiring board with a longitudinal direction of the printed wiring board as the axial direction. The core body and the one or more pressure-sensitive components are held by the core body engaging portion and the component disposing portion in such a way that their central positions are aligned with each other in a predetermined position.

16. A position indicator, comprising:
-
a cylindrical chassis defining a tip end at its distal end and a proximal end along its axial direction; and an elongate holder enclosed in the cylindrical chassis, the holder including; a core body engaging portion configured to hold an elongate core body having a tip such that said tip protrudes from said tip end of the cylindrical chassis, a component disposing portion, which defines an opening portion that opens in a direction perpendicular to the axial direction and in which one or more pressure-sensitive components are arranged in the axial direction so as to receive a pressing pressure applied to the tip of the core body, the one or more pressure-sensitive components being configured to detect a displacement of the core body, in the axial direction, caused by application of the pressing pressure to the tip of the core body, and a printed wiring board mounting portion configured to mount thereon a printed wiring board including a circuit element to detect the pressing pressure applied to the tip of the core body; wherein the pressing pressure is applied to the tip of the core body within the holder such that the pressing pressure is not directly applied to the cylindrical chassis that encloses the holder. - View Dependent Claims (17, 18, 19, 20)
