Abstract

PURPOSE: To make it possible to record not only given images like written characters but also projected images from a projector on the recording sheet as displayed by equipping light guiding means that guides light of given images like characters and projected images to scanner. CONSTITUTION: Scanner 2 conducts reading of image on sheet 1 while moving front face of the sheet 1, and records its read image on recording sheet by means of printer 3. At this stage, image light from given image G like written characters is reflected by half mirror 8 or prism 9 and incident into interior of the scanner 2, and read by CCD image sensor 5. Projected light from projector O passes through the half mirror 8 or prism 9 without hindrance by the scanner 2 and projected on surface of the sheet 1 to make the image thereon. Image light from projected image H is also reflected by the half mirror 8 or prism 9 and incident into interior of the scanner 2, and can be read by the CCD image sensor 5.
