A pattern erasably written on a black board or a flexible sheet in a meeting is printed to a hard copy through scanning of the pattern by an image sensor which provides an electrical signal relating to the pattern, and printing the pattern on a paper according to said electrical signal. The present print board comprises a housing, a writing sheet or a black board mounted on said housing, an elongated lamp for illuminating an elongated portion of said sheet, an image sensor to provide an electrical signal relating to the pattern on a scanning line on the sheet illuminated by said lamp, means for relatively moving said image sensor to said sheet for full scanning of the pattern, and a printer for providing a hard copy of the pattern with smaller size than said pattern according to said electrical signal from said image sensor. The present print board has also a digital memory for storing the output of the image sensor for the late printing, and/or means for transmitting and receiving the pattern signal to and from a telephone line for a remote printing.
