PROBLEM TO BE SOLVED: To provide an electronic white board device, which is efficient in design, manufacturing and maintenance and which has a high interchangeability, by standardizing circuits having possibility of being standardized as much as possible to a printer, which is installed on the electronic white board device and has resolutions different from one another. SOLUTION: In an electronic white board device, in which image information written in the writing surface of a screen sheet is read at an optical reading part and converted to electric signals so as to record the image information of a paper after the signals are processed at circuit boards 1 and 3, variable power circuits 36-38, which variably powers electric signals in response to the resolution of the printer 18, is housed in a circuit board 34, which is separated from the circuit boards 1 and 3.
