Abstract
A plurality of core bodies are housed within a casing having an opening portion on one end side. A core body selecting mechanism is provided which includes a plurality of operating portions coupled to each of the plurality of core bodies, and makes at least a tip of one core body among the plurality of core bodies selectively project from the opening portion of the casing. A pen pressure detecting portion common to the plurality of core bodies is provided within the casing. When the operating portion is operated to make at least the tip of the one core body project from the opening portion, part of the operated operating portion engages with the pen pressure detecting portion common to the plurality of core bodies, and the pen pressure detecting portion detects a pen pressure applied to the tip projected from the opening portion.
Claims20
A position indicator, comprising:
- a tubular casing having an opening;
- a plurality of core bodies housed within the tubular casing;
- a plurality of operating members coupled to respective core bodies of the plurality of core bodies, a selected operating member of the plurality of operating members making at least a tip of one core body coupled to the selected operating member project through the opening;
- and
- a pen pressure detector common to the plurality of core bodies, the pen pressure detector being positioned within the casing,
- and, in response to the selected operating member making at least the tip of the one core body project from the opening, the pen pressure detector being engaged with a side of the selected operating member that is opposite to a side of the selected operating member coupled to the one core body, and a pen pressure applied to the tip of the one core body being detected by the pen pressure detector.
A device, comprising:
- a casing;
- a pressure sensor;
- a first core body including a tip and a base, the first core body having a first state in which the tip of the first core body is within the casing and a second state in which the tip of the first core body is external to the casing;
- a first movable member which, in operation, changes the first core body between the first state to the second state, the first movable member including a mount that is coupled to the base of the first core body and a protrusion that contacts the pressure sensor when the first core body is in the second state;
- a second core body including a tip and a base, the second core body having a first state in which the tip of the second core body is within the casing and a second state in which the tip of the second core body is external to the casing;
- and
- a second movable member which, in operation, changes the second core body between the first state to the second state, the second movable member including a mount that is coupled to the base of the second core body and a protrusion that contacts the pressure sensor when the second core body is in the second state.
A method, comprising:
- selecting a first operating member;
- changing, in response to selecting the first operating member, a first core body from a first state in which a tip of the first core body is within a casing to a second state in which the tip of the first core body is external to the casing;
- engaging the first operating member with a pressure sensor when the first core body is in the second state;
- measuring, in response to engaging the first operating member with the pressure sensor, a pressure applied to the tip of the first core body;
- selecting a second operating member;
- changing, in response to selecting the second operating member, the first core body from the second state to the first state;
- changing, in response to selecting the second operating member, a second core body from a first state in which a tip of the second core body is within the casing to a second state in which the tip of the second core body is external to the casing;
- engaging the second operating member with the pressure sensor when the second core body is in the second state;
- and
- measuring, in response to engaging the second operating member with the pressure sensor, a pressure applied to the tip of the second core body.
