Electronic pen including a pressing member having an extension that extends along an outer wall of a writing-pressure detector

An electronic pen that indicates a position to a position detection module by transmitting and receiving signals with the position detection module, comprising:

• a cylindrical casing;
• a core member accommodated in an interior portion of the casing, the core member including a first end and a second end serving as a pen tip, the first end of the core member being opposite the second end of the core member serving as the pen tip;
• a writing-pressure detector disposed in the interior portion of the casing on the first end of the core member;
• a writing-pressure transmission member disposed in the interior portion of the casing, between the first end of the core member and the writing-pressure detector;
• and
• a pressing member which, in operation, applies, based on an operation by a user, a force to the core member from the first end of the core member to the second end of the core member serving as the pen tip,
• wherein the writing-pressure transmission member includes a protrusion which, in operation, transmits a writing pressure to the writing-pressure detector, the writing pressure being exerted on the core member fitted in a fit-in portion included in the writing-pressure transmission member,
• wherein the pressing member, in operation, applies the force to the core member via the writing-pressure transmission member without applying an axial force to the writing-pressure detector, and
• wherein the pressing member is disposed through a side circumferential wall of the casing and is moveable in a direction orthogonal to an axial direction of the casing, and, when actuated, engages the writing-pressure transmission member and applies, to the writing-pressure transmission member, the force applied to the pressing member, which causes a core of the core member to move toward a pen tip side of the casing.

A method comprising:

• providing an electronic pen that indicates a position to a position detection module, wherein the electronic pen includes a cylindrical casing, a core member accommodated in an interior portion of the casing, the core member including a first end and a second end serving as a pen tip, the first end of the core member being opposite the second end of the core member serving as the pen tip, a writing-pressure detector disposed in the interior portion of the casing and coupled to the core member, a writing-pressure transmission member disposed in the interior portion of the casing between the core member and the writing-pressure detector, and a pressing member that is operable by a user, wherein the pressing member is provided on a first side of the writing-pressure detector, the first side of the writing-pressure detector being opposite a second side of the writing-pressure detector where the writing-pressure transmission member is fitted, and the pressing member includes an extension, the extension extending along an outer wall of the writing-pressure detector and being in engagement with a first end of the writing-pressure transmission member, the first end of the writing-pressure transmission member being opposite a second end of the writing-pressure transmission member on which the fit-in portion is provided;
• transmitting a writing pressure that has been exerted on a pen tip portion of the core member, from a protrusion of the writing-pressure transmission member to the writing-pressure detectors;
• and
• applying a force applied to the pressing member to the core member via the writing-pressure transmission member without applying an axial force to the writing-pressure detector.

A method comprising:

• providing an electronic pen that indicates a position to a position detection module, wherein the electronic pen includes a cylindrical casing, a core member accommodated in an interior portion of the casing, the core member including a first end and a second end serving as a pen tip, the first end of the core member being opposite the second end of the core member serving as the pen tip, a writing-pressure detector disposed in the interior portion of the casing and coupled to the core member, a writing-pressure transmission member disposed in the interior portion of the casing between the core member and the writing-pressure detector, and a pressing member that is operable by a use, wherein the pressing member is disposed through a side circumferential wall of the casing and is movable in a direction orthogonal to an axial direction of the casing;
• engaging the pressing member with the writing-pressure transmission member;
• transmitting a force from the pressing member to the writing-pressure transmission member;
• and
• moving a core of the core member toward a pen tip side of the casing in response to the transmitting of the force from the pressing member to the writing-pressure transmission member.
