An electronic print board apparatus optically reads characters and figures, etc., written on a plate surface to scale down and print them, and includes a writing unit, a frame, a scanning unit, and a printer. The writing unit is divided into two sections, each of which has a plurality of stacked writable flat plates, a writing surface being formed by a front row of the two sections. The writing surface can be changed by rotating and moving one flat plate of the two flat plates located in the front row to the position of the other flat plate. The scanning unit is supported movably on the frame and includes a drive for causing such movement, a read unit having a sensor for generating a read signal, a synchronization device for synchronizing the scanning by the read unit with the speed of movement of the scanning unit, a battery for supplying power, and a transmitter for transmitting the read signal. The scanning unit optically scans the writing surface and issues the read signal. The printer receives the red signal transmitted from the scanning unit and prints in conformity with such signal.
