Abstract
An input device for inputting coordinates to a coordinate detector includes an operation detector to detect whether a coordinate input operation to the coordinate detector is conducted; a signal generation unit to generate an operation-in-progress signal indicating an operation is in progress when the operation detector detects the coordinate input operation; a signal outputting unit to output the operation-in-progress signal generated by the signal generation unit; and a light guide member to guide the operation-in-progress signal output by the signal outputting unit to an exit position.
Claims9
An input device for inputting coordinates to a coordinate detector, comprising:
- an operation detector to detect whether a coordinate input operation to the coordinate detector is conducted;
- a signal generation unit to generate an operation-in-progress signal indicating an operation is in progress when the operation detector detects the coordinate input operation and the operation-in-progress signal is a light signal;
- a signal outputting unit to output the operation-in-progress signal generated by the signal generation unit;
- a light guide member to guide the operation-in-progress signal output by the signal outputting unit to an exit position, and the light guide member includes:
- an input end and an output end opposite with each other,
- a diffusion member provided to the output end so that light is diffused and emitted, and
- an opening of the light guide member that faces the signal outputting unit;
- a casing of cylindrical shape;
- and
- a moveable unit disposed at least at one end of the casing, the moveable unit being moveable in an axis direction of the casing when the moveable unit contacts the coordinate detector,
- wherein the signal generation unit generates the operation-in-progress signal corresponding to a movement of the moveable unit.
An input device for inputting coordinates to a coordinate detector, comprising:
- a switch to detect whether a coordinate input operation to the coordinate detector is conducted;
- circuitry configured to generate an operation-in-progress signal indicating an operation is in progress when the switch detects the coordinate input operation, and the operation-in-progress signal is a light signal;
- a light emitting diode (LED) to output the operation-in-progress signal generated by the circuitry;
- an optical fiber to guide the operation-in-progress signal output by the LED to an exit position, and the optical fiber includes:
- an input end and an output end opposite with each other,
- a lens provided to the output end so that light is diffused and emitted, and
- an opening of the optical fiber that faces the LED;
- a casing of cylindrical shape;
- and
- a moveable structure disposed at least at one end of the casing, the moveable structure being moveable in an axis direction of the casing when the moveable structure contacts the coordinate detector,
- wherein the circuitry is configured to generate the operation-in-progress signal corresponding to a movement of the moveable structure.
