Claim Text:
1. 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: 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.
