Abstract

PURPOSE:To project an image in a home position all the time, to write a new image by viewing a projected image, to erase an image by viewing the projected image and to quickly return the image having been projected by traveling and stopping a writing medium sheet where images about characters, symbols, graphics, etc., are stated in one-page units. CONSTITUTION:When a page mark sensor 35 detects a page mark and outputs it to a control circuit part, said part stops a motor. Since writing-in range marks agree with four corners of a Fresnel lens 25, projected light beams 45 from a light source 3c hit a reflecting member 26, which reflects said beams. Reflected light beams 46 transmit the Fresnel lens 25 and the writing-in range marks on the writing medium sheet 1, and get to a screen 31 through a projecting lens 3b and a magnifying glass 2 for projecting, thereby projecting an image. When a return mode button is pressed, the control circuit part drives the motor, and the sheet 7 travels by one page, then stops. In case of copying, when a prescribed button is pressed, the writing medium sheet 7 begins to travel, while the control circuit part begins to copy.
