    Abstract: 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.

    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: 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.

    Abstract: 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.
