An object of the present disclosure is to provide an electronic pen that is excellent in portability by being reduced in size, that has a side switch functioning stably, and that is easy to maintain. A pusher part of an electronic pen body part is inserted into an insertion part of an operator, and the operator is thus attached to the pusher part of the electronic pen body part in a state of being fitted into an operator opening part of an outer casing. The operator opening part of the outer casing is formed in a side surface thereof at a position corresponding to a button switch of the electronic pen body part being loaded into the outer casing and placed at a fixed position. Therefore, the button switch can reliably be depressed through the operator, and the side switch of the electronic pen is realized.

Provided is an electronic pen including a housing that is cylindrical and configured to incorporate an electronic pen function part that includes a circuit board. The housing has a side opening formed on a side surface of the housing. The side opening is configured to accommodate a side switch. The electronic pens also includes a side attachment member configured to be attached to the side opening of the housing. A first axial end of the side attachment member includes an engagement part that engages with the housing, and a second axial end of the side attachment member includes a pressed part. The housing incorporates a pressing mechanism part that presses the pressed part of the side attachment member attached to the side opening, toward the first axial end of the side attachment member.

Electronic pen

Provided is an electronic pen including a tubular housing having an opening at one end, a core body portion including a rod-shaped core body and a pressure member that holds a rear end of the core body and transmits a force applied to the core body, a writing pressure detector that detects a writing pressure applied to the core body, and a tubular holding member that accommodates and holds the core body portion. At least part of a side surface of the core body portion includes a flat surface portion parallel to an axial direction of the pen. An inner edge of the holding member has a cylindrical shape and at least part of the inner edge includes a protruding portion. With the core body portion mounted in the housing, the flat surface portion of the core body portion and the protruding portion of the holding member face each other.

Provided is an electronic pen that includes a circuit board including one or more push switches, a housing having a cylindrical body in which an electronic pen circuit including the circuit board is mounted, the housing including a side opening at a position corresponding to a range in which the one or more push switches are provided on the circuit board mounted at a predetermined position, a board protection member including a main body part and one or more depression parts, and a side attachment member including a plate part and one or more push parts. When one of the one or more push parts of the side attachment member is pushed down, a corresponding one of the one or more push switches on the circuit board is pushed down via a corresponding one of the one or more depression parts of the board protection member.

Provided is an electronic pen including an electronic pen main part including a first sealing member that covers circumference of a tip side of the electronic pen main part and a second sealing member disposed along an outer edge of the electronic pen main part at a position separate from a tip toward a rear end side of the electronic pen main part, and an inside body that is tubular and has an inner wall surface with which the first sealing member and the second sealing member come into contact through insertion of the tip side of the electronic pen main part into the inside body.

Provided is an electronic pen with a cylindrical housing including an opening at an end portion of the housing on a pen tip side of the housing, a cylindrical member disposed in the housing and fixed to the housing at a part on the pen tip side of the housing, and a core body formed in a rod shape by a material containing a pigment, the core body including a body portion inserted into the cylindrical member through the opening of the housing and a pull-out portion configured to enable the core body to be pulled out of the housing. A diameter of the body portion of the core body inserted into the cylindrical member is larger than a difference between an outer diameter of the cylindrical member and an inner diameter of the cylindrical member.

An electronic pen includes a first casing, a second casing disposed within the first casing, and an electronic pen main body unit incorporating an electronic pen function disposed within the second casing, in which the electronic pen main body unit includes a side switch unit having an operating element exposed on a side surface of the second casing, and an operating opening portion is disposed in a side surface of the first casing, and the operating opening portion exposes the operating element exposed on the side surface of the second casing.

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.

Stylus

An electronic pen indicates a position to a position detection module by transmitting and receiving signals with the position detection module. A cylindrical casing, a core member, a writing-pressure detector, and a writing-pressure transmission member are accommodated in a interior portion of a cylindrical casing. A pressing member applies, based on a user operation, a displacement force to the core member from a first end, which is opposite to a second end serving a pen tip, to the second end serving as the pen tip. The writing-pressure transmission member includes a protrusion which, in operation, transmits a writing pressure, which has been exerted on the core member fitted in a fit-in portion included in the writing-pressure transmission member, to the writing-pressure detector. The pressing member is configured to apply a displacement force to the core member via the writing-pressure transmission member without applying an axial force to the writing-pressure detector.

A position pointing device includes a pressure detecting part which detects a pressure applied in an axial direction of a core body. The core body includes: a leading end part formed from an elastic material; a pedestal part which is formed from a material harder than the material of the leading end part and is joined to the leading end part; and a core body main body part which is joined to the pedestal part, is smaller than the pedestal part in thickness in a direction orthogonal to the axial direction, and is formed from a hard material. The core body is housed in a casing and is movable in the axial direction, such that the leading end part is exposed via an opening of the casing, and a pressure exerted on the leading end part in the axial direction is transmitted to the pressure detecting part.

Position pointing device and core body for position pointing device

A position indicator includes a first electrode receiving an alternating current (AC) signal from a position detecting sensor and a second electrode transmitting an AC signal to the position detecting sensor. The position indicator includes: a tubular pen-shaped chassis; a central electrode provided such that one end protrudes outside of the chassis from an opening of the chassis, and formed of an electrically-conductive member forming a first one of the first and second electrodes; a peripheral electrode surrounding the central electrode and formed of an electrically-conductive member forming a second one of the first and second electrodes; and a shield member having a hollow part housing at least a part of the central electrode surrounded by the peripheral electrode. The shield member includes a tubular part electrically connected to ground and an insulating layer formed on an inner wall surface and an outer wall surface of the tubular part.
