POSITION POINTER, VARIABLE CAPACITOR AND INPUTTING APPARATUS
First Claim
1. A position pointer, comprising:
- a housing;
a rod accommodated in said housing such that one end thereof projects to an outer side of said housing; and
a variable capacitor having a capacitance value which varies in response to external force applied thereto through said rod;
said variable capacitor including;
a dielectric member having a first face portion and a second face portion opposite from said first face portion,a terminal member configured to engage with said first face portion of said dielectric member,an electrode section disposed in an opposing relationship to said second face portion of said dielectric member and including a conductive member having a contact area with said second face portion that varies in response to the external force, andan elastic member configured to bias said conductive member in a direction in which said conductive member is spaced away from said second face portion.

Abstract
A position pointer is disclosed, including a housing, a substantially bar-like rod accommodated in the housing such that one end thereof projects to the outer side of the housing, and a variable capacitor having a capacitance value which varies in response to external force applied thereto through the rod. The variable capacitor includes a dielectric member having a first face portion and a second face portion opposite from the first face portion, a terminal member configured to engage with the first face portion of the dielectric member, an electrode section disposed in an opposing relationship to the second face portion of the dielectric member and including a conductive member having a contact area with the second face portion that varies in response to the external force, and an elastic member configured to bias the conductive member in a direction in which the conductive member is spaced away from the second face portion.

19. An inputting apparatus, comprising:
-
a position pointer including a housing, a rod accommodated in said housing such that one end thereof projects to an outer side of said housing, and a variable capacitor having a capacitance value which varies in response to external force applied thereto through said rod; and a position detection apparatus having a detection face to be pointed to by an end of said rod and being configured to detect a position pointed to by the end of said rod; said variable capacitor including; a dielectric member having a first face portion and a second face portion opposite from said first face portion, a terminal member configured to engage with said first face portion of said dielectric member, an electrode section disposed in an opposing relationship to said second face portion of said dielectric member and including a conductive member having a contact area with said second face portion that varies in response to the external force, and an elastic member configured to bias said conductive member in a direction in which said conductive member is spaced away from said second face portion.
