PURPOSE: A multi-functional electronic blackboard is provided to display the contents written on the blackboard on a PC as they are and, reversely, display the contents of the PC on the blackboard through a projector. CONSTITUTION: An electronic blackboard(5) is mounted with a infrared sensor and an ultrasonic sensor on a frame(1) and has a front surface formed of a sheet panel(4) in white serving as a screen or display panel. A PC(7) is connected to the electronic blackboard(5) by a cable(6) branched in two directions so as to communicate with the electronic blackboard(5) in both directions.
