PURPOSE:To print instantly a character and a graph on a blackboard and to transmit externally the information by providing a sensor converting the character or graph or the like drawn on a writing medium provided at a required position of a case into an electric signal and a printing head printing and recording the output of the sensor on a recording medium. CONSTITUTION:The case, a roller fitting metallic fixture and a board of the electronic blackboard device are fixed to a wall face. Further, the sensor is adhered closely to a sheet between turning rollers 2, 3 and fixed by the roller fitting metallic fixture. The character or graph or the like written manually on this sheet is applied to a control section and a motor driving section by the command of an operating section 4 to drive the motor 14. Further, the character or graph of the sheet is moved beneath a lens 23, and its image is formed on an image sensor 24. The electric signal read by the sensor 24 is transmitted to a circuit section. This signal is converted digitally, applied to a print head 52 via a print control section, printed on the sheet between the heads 52 and transmitted to the line from a storage device. |
