PROBLEM TO BE SOLVED: To enhance the workability of a device even when much time is required for transferring data to a printer by controlling the starting of the movement of a screen sheet to an arbitrary direction by inputting a sheet feeding key or the like under the state that the starting is executed after the finish of the reading at an optical reading part even under the condition that the printer is under printing. SOLUTION: An electronic white board device is constituted by reading an image information written in the writing surface S of a screen sheet 15 at an optical reading part 14 during the motion of the screen sheet 15 so as to electrically process the image information read at the optical reading part 14 and, after that, print it with a printer 18 on a paper. The arbitrary start of the movement of the screen sheet 15 is controlled after the reading of the image information at the optical reading device of this electronic white board device and under the printing of the image information with the printer. In this case, the arbitrary stopping of the movement of the screen sheet 15 can be preferably controlled and the continuous movement until the finish of the movement of the screen sheet 15 is preferable even when printing comes to an end.
