Abstract

Abstract An electronic print board comprising: a recording medium formed by a flexible sheet for recording erasable recordings and/or drawings or for holding a data sheet thereon, a mechanism for moving said recording medium, a scanning system for scanning the writings and/or drawings or data carried on a data sheet secured on the recording medium and providing electric signals corresponding to the writings and/or drawings or the data, operating unit including sheet size selecting switches, an image memory for storing data corresponding to the writings and/or drawings or the data carried on a data sheet secured on the recording medium. A control circuit for controlling the scanning operation of the scanning system, reading data from the image memory and printing the data on a printing sheet, and a reading and printing unit for reading data from the image memory and printing the data read from the image memory under the control of the control circuit. The electronic print board is capable of scanning the entire area of the surface of the recording medium or only a limited area of the same corresponding to a size of sheet selected, of printing the data corresponding the entire area of the recording medium or only the data within a limited area corresponding to a size of a data sheet selected by means of one of the sheet size selecting switches, and of producing one copy or a plurality of copies of the same data.
