Abstract: A highly reliable waterproof electronic pen includes a board holder in a board housing including a recessed portion having an opening over a lower surface of the recessed portion. A circuit board is housed in the recessed portion of the board housing. Circuit components easily affected by heat are installed on a first surface of the circuit board, and circuit components not easily affected by heat are installed on a second surface of the circuit board. A thermosetting resin formed over the second surface of the circuit board when the circuit board is housed in the recessed portion seals the opening over the lower surface of the recessed portion of the board housing.

Abstract: 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.

Abstract: 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.

Abstract: An electronic pen includes a circuit board disposed such that an axial direction of a casing is aligned with a longitudinal direction of the circuit board, an electronic circuit on the circuit board, and a battery having a columnar shape disposed on a side of the circuit board opposite to a pen tip side of the circuit board inside a hollow portion of the casing such that positive and negative electrode conductors protruding from an end surface of the battery extend toward the circuit board. The battery is disposed such that a separation space is formed between the end surface and an end portion of the circuit board and such that tip portions of the positive and negative electrode conductors are in contact with the circuit board. The circuit board and the tip portions of the positive and negative electrode conductors are electrically connected to each other by soldered portions.

Abstract: A position pointer has a tubular housing having a first opening portion at one longitudinal end. A rod-shaped core body is arranged in the housing with a first end of the core body opposed to the first opening portion. A writing pressure detection circuit is arranged in the housing, which, in operation, detects a writing pressure based on movement of the core body. A signal transmitter is arranged in the housing, which, in operation, transmits a signal. The position pointer includes an elastic block of material sized and shaped to form a seal with an inner surface of the housing and positioned near the first end of the core body.

Abstract: An electronic pen includes a casing, an opening portion formed on one side of the casing, a core body that projects outside of the casing through the opening portion, a pen module part, and a core body insertion member disposed in the casing and having a hollow space that houses the core body. The hollow space includes a hollow portion between an inner circumferential surface of the core body insertion member and an outer circumferential surface of the core body when the core body insertion member houses the core body, the hollow portion communicating, via the opening portion, with a first space external to the electronic pen. The hollow portion is separated from a second space in which the pen module part is disposed within the casing.
