INPUT DEVICE AND ELECTRONIC INFORMATION BOARD SYSTEM

摘要

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.
