Abstract: An electronic pen includes: a tubular casing; a rod-shaped core body that projects outside of the casing through an opening of the casing, the opening being formed on one side in axial direction of the casing; a pen pressure detector disposed within a hollow portion of the casing, wherein the pen pressure detector, in operation detects a pen pressure applied to the core body; a core body insertion member disposed between the pen pressure detector and the opening of the casing within the hollow portion of the casing, the core body insertion member housing the core body movably in the axial direction of the casing and having a hollow space closed on a side of the pen pressure detector by a barrier; and a first sealing member that separates the hollow space of the core body insertion member from the hollow portion of the casing.

Abstract: An electronic pen includes an electronic pen main body section coupled to a side of a housing that includes an opening. The electronic pen main body section includes: an axial portion that is put into a hollow portion of the housing via the opening; and a tip portion that is coupled to the axial portion and externally exposed from the opening of the housing. A diameter of the tip portion is larger than a diameter of the opening of the housing. A coupling side of the tip portion includes a second ring-shaped end face that comes into contact with a first ring-shaped end face on the side of the housing that includes the opening. The electronic pen main body section includes a stepped portion on a coupling area between the tip portion and the axial portion.

Abstract: A stylus includes in a tubular casing a core body, a pressure detector that detects a pressure applied to the core body, a coupling fitted over the core body, the coupling transmitting the pressure to the pressure detector, and a core pressing controller that controls the coupling to press the core body axially in the tubular casing. The coupling includes a push bearer that bears a push from the core pressing controller, a presser having an axial end fitted in the pressure detector, a fitting region fitted over a portion of the core body remote from a pen tip end of the tubular casing, a receptacle in which another end of the presser remote from an axial end thereof is axially movably housed, and an elastic member disposed in the receptacle, the elastic member biasing the other end of the presser resiliently toward an axial pen tip end of the receptacle.
