ABSTRACT:
An electronic white-board apparatus having a writable screen, a reader for reading information on a screen and outputting the information as image data, a printer for printing and recording the image data output from the reader onto a recording medium, and an external interface which is connectable to external equipment and can output the image data from the reader. Data obtained by reading information on the screen can be output to external information equipment such as personal computers for editing purposes. Information written on a screen (1) is read by a CCD (9), and stored in an image memory (13) through an A/D converter (10), magnification and reduction circuit (11), and binarizer (12). A CPU (14) determines whether a laser printer (18) or personal computer (20) is connected to a parallel interface connector (17). If one of them is connected, data stored in the image memory (13) is output to the laser printer (18) or personal computer (20). If none of them is connected, the data in the image memory (13) is output to a thermal printer (16).
