Abstract
Abstract An electronic print board apparatus for optical reading of characters and figures, etc., written on a plate surface and operable to scale down and print them. The apparatus includes a writing part (10), a frame part (20), a scanning part, and a printing part (111). The writing part (10) is divided into two sections, each of which has a plurality of stacked writable flat plates, a writing surface being formed by the front rows of said two sections. The writing surface can be changed by rotating and moving one flat plate of the two flat plates located on the front row to the position of the other flat plate. The scanning part is supported movably on said frame part (20), and incorporates drive means for said movement, a read part (32) having a sensor (32a), synchronization means (33) for synchronizing the scanning by said read part (32) with the moving speed of said scanning part, a battery (107) for supplying power, and transmitting means for transmitting the read signal by making use of radio, for optically scanning the writing surface and for thereby issuing the read information. The printing part (111) has receiving means for receiving the information transmitted from said scanning part and prints in conformity with said information.
