Abstract: There is provided a terminal device including electronic paper and a position detection sensor disposed on a lower side of a display screen of the electronic paper and configured to detect a position indicated by an electronic pen on the display screen. The position detection sensor includes an insulating substrate having a first surface on a side facing the display screen, and a plurality of first electrodes arranged in a first direction on the first surface of the insulating substrate. One or more first linear members extended in a direction along the first electrodes are arranged in each space between two of the first electrodes having a predetermined distance from each other in the first direction, among the plurality of first electrodes, on the first surface of the insulating substrate.

Abstract: A knock-type electronic pen including a tubular casing, a first position indicator such as a written input indicator, a second position indicator such as an eraser, a knock cam mechanism, and a holding mechanism. The knock cam mechanism includes a knock portion including a part protruding outward from an opening at a second end of the tubular casing, and is configured to cause a tip of the first position indicator to protrude from, or be housed within, an opening at a first end of the tubular casing. The holding mechanism, in the state in which the tip of the first position indicator protrudes from the opening at the first end, returns the knock portion pushed into the tubular casing to a state of protruding from the opening at the second end such that at least a tip of the second position indicator protrudes outward.

Abstract: A position detection device includes a position detection sensor that is used with a position indicator and includes a sensor-substrate main body including electrodes and a cable section to which the electrodes are led out. The position detection device includes a circuit board including a position detection circuitry to which the position detection sensor is connected. The sensor-substrate main body includes an insulating substrate having a first surface that is located on a side where a position is to be indicated by the position indicator and a second surface opposite from the first surface. The circuit board is connected to the cable section on a surface of the cable section contiguous with the first surface of the sensor-substrate main body, and when the cable section is bent toward the second surface of the sensor-substrate main body, the circuit board is positioned at a lowermost layer of the position detection device.

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.
