  • Electronic pen and cartridge for electronic pen
    Patent number: 11269464
    Abstract: An electronic pen includes a tubular casing, and a first coupling member and a second coupling member that are coupled to each other in a hollow portion of the casing in an axial direction of the casing. In the axial direction, the first coupling member and the second coupling member are coupled to each other, and in a coupling portion between the first coupling member and the second coupling member, a welded portion that attaches the first coupling member and the second coupling member to each other is formed. The first coupling member is coupled to a core. The second coupling member holds a printed circuit board. The core of the core-side component is made of a conductive material. The second coupling member includes a conductor that supplies, to the core, a signal from a signal transmitting circuit on the printed circuit board with a battery.

    Patent number: 11010002
    Abstract: An electronic pen includes a tubular casing, and a first coupling member and a second coupling member that are coupled to each other in a hollow portion of the casing in an axial direction of the casing. In the axial direction, the first coupling member and the second coupling member are coupled to each other while partially overlapping each other, and in a coupling portion between the first coupling member and the second coupling member, a welded portion that attaches the first coupling member and the second coupling member to each other is formed.
