    Abstract: A position detection apparatus includes a sensor, and a controller that detects a position of a first position indicator and a position of a second position indicator through the sensor. The controller continues detecting the position of the first position indicator and halts detecting the position of the second position indicator after a state in which the positions of the first position indicator and the second position indicator are not detected changes to a state in which the position of the first position indicator is detected, and continues both detecting the position of the second position indicator and detecting the position of the first position indicator after the state in which the positions of the first position indicator and the second position indicator are not detected changes to a state in which the position of the second position indicator is detected.

    Abstract: An integrated circuit includes a first terminal that is connected to a first end of a first capacitor, the first capacitor being included in a resonant circuit, a second terminal that is connected to a second end of the first capacitor, a plurality of second capacitors connected in parallel between the first and second terminals, and a control circuit which, in operation, changes a capacitance of each of the second capacitors. An electronic pen includes the integrated circuit and a first capacitor having a capacitance that varies based on pressure applied to a nib of the electronic pen.

    Abstract: A work step of electrical connection between a writing pressure detector and a circuit element of a circuit is reduced. An electronic pen includes a writing pressure detector that detects a pressure applied to a core body disposed on one end side of a tubular chassis in the axial center direction, a circuit board for which a flexible substrate formed into a shape allowed to extend in the axial center direction is used in the chassis, and a holder housed in the chassis in such a manner as to hold the writing pressure detector and the circuit board and extend in the axial center direction. In the circuit board, a writing pressure detector placement part, a circuit placement part at which a predetermined circuit is formed, and a line part at which a line pattern that electrically connects a component of the writing pressure detector placed on the writing pressure detector placement part and a circuit element of the circuit placement part is formed are formed to line up in the axial center direction. The writing pressure detector placement part of the circuit board is held by the holder in the state of being along a direction perpendicular to the axial center direction in such a manner that the writing pressure detector can receive a pressure in the axial center direction applied to the core body through bending of the flexible substrate at a part of the line part.

    Abstract: An electronic pen cartridge includes a pen tip that is configured to protrude outside of an electronic pen electronic pen casing through an opening of the electronic pen casing, an electronic circuit that transfers signals to a position detecting sensor, and a first connector that is joined to a second connector disposed in the electronic pen casing. The first connector includes plural terminals insulated from each other, and each of the terminals is electrically connected to the electronic circuit. The first connector and the second connector are joined through insertion of a fitting protrusion of a first one of the first connector and the second connector into a fitting recess of a second one of the first connector and the second connector in an axis center direction of the electronic pen casing, and circular annular conductor contacts are included in the first connector or the second connector.

    Abstract: Provided is an electronic pen core body including a tip component portion coupled to an axis component portion. At least one end of the axis component portion in an axial direction is made of a material that is harder than a material from which the tip component portion is made. The axis component portion includes a recessed hole and a fitting portion directly or indirectly fitted to a pen pressure detector. The tip component portion includes a tip portion protruding from the one end of the axis component portion in the axial direction, a coupling core portion disposed within the recessed hole and coupled to an inner wall surface of the recessed hole of the axis component portion, and a second ring-shaped end surface that contacts a first ring-shaped end surface of the axis component portion. The first ring-shaped end surface is covered by the second ring-shaped end surface.
