Abstract
A position indicator that enables a component having a writing function to be easily replaced. The component having the writing function can be inserted/extracted into/from a first housing through a second opening of the first housing. When the second opening of the first housing and a third opening of a second housing are engaged in a state in which the component having the writing function has been inserted into the first housing, a resonant circuit is formed that includes a circuit in which a coil inside the first housing and a writing pressure detector inside the second housing are electrically connected to each other.
Claims13
A position indicator comprising:
- a first housing having a first opening portion at a first end of the first housing where a pen tip of a component having a writing function is located and a second opening portion at a second end of the first housing for inserting and removing the component having the writing function;
- a coil located inside the first housing and on a side of the first housing closer to the first opening portion than the second opening portion;
- a second housing having a third opening portion that engages with the second opening portion of the first housing;
- a writing pressure detector that is located inside the second housing and that, in operation, detects a writing pressure applied to the pen tip of the component having the writing function;
- a resonance circuit including a circuit in which the coil and the writing pressure detector are electrically connected in a state where the second opening portion of the first housing and the third opening portion of the second housing are engaged with each other;
- a first terminal member located inside the first housing and electrically connected to the coil;
- and
- a second terminal member located inside the second housing and electrically connected to the writing pressure detector,
- wherein the first terminal member and the second terminal member are electrically connected in the state where the second opening portion of the first housing and the third opening portion of the second housing are engaged with each other, and
- wherein the first terminal member and the second terminal member are electrically disconnected in a state where the second opening portion of the first housing and the third opening portion of the second housing are separated from each other.
