Abstract:
A cordless type position pointer is provided for use with a capacitance type position detection apparatus to carry out a position pointing operation. The position pointer includes a housing having electric conductivity, a projecting portion of a predetermined shape formed at one end portion of the housing and having electric conductivity, and a contacting member removably fitted with the projecting portion. The contacting member has elasticity and electric conductivity, and is configured to contact the position detection apparatus to point to a position. The position pointer further includes a sleeve having a through-hole and configured to expose, when the sleeve is engaged with the housing, a predetermined portion of the contacting member fitted with the projecting portion from the through-hole thereof. The sleeve is configured and arranged so as to prevent application of displacing force in response to a position pointing operation of the position pointer to the fitting portion between the projecting portion and the contacting member in a direction against the major axis of the position pointer, to thereby prevent dislodging of the contacting member from the housing while maintaining removability of the contacting member from the housing.
