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: An electronic pen central rod is provided. The electronic pen central rod includes a connection member having a front end and a back end, and a front-end member having a pen tip part and a back-end extension part that extends in an opposite direction from the pen tip part to be detachably held by the front end of the connection member with a first level of holding strength. The electronic pen central rod further includes a back-end member having an attachment part to be attached to an electronic pen interior and a front-end extension part that extends in an opposite direction from the attachment part to be held by the back end of the connection member with a second level of holding strength. The second level of holding strength is higher than the first level of holding strength.
