Abstract

An electronic blackboard system with a PDP for displaying characters and images. A touch input device with a touch panel surface is provided on the front surface of the PDP. A printer outputs image data onto recording paper. A computer provides control over displays on the PDP as well over the printing operations of the printer according to the input from the touch input device. A frame unit has a board section for holding a display surface and a write-in surface of the electronic blackboard at a specified height. A printer accommodating section accommodates the printer and a computer accommodating section accommodates the computer therein. The computer accommodating section, the printer accommodating section and the board section are arranged in the vertical direction starting from the bottom.
