PURPOSE:To move a screen in a space in a form of plane by providing in structure with the printing head of a printer device, using an optical fiber cable and using a tractor feeder in the printer device. CONSTITUTION:An objective lens 1 for forming the image of a picture on a screen 6 to be scanned on the end surface of an optical fiber cable 2, a relay lens 3 for transmitting this image formed information through the cable 2 to form the image in the space and radiating on the screen 1 in transmitting picture information by passing the light of a light source 5 through the cable 2 and a half mirror 4 for guiding the formed image in the space to a video camera and changing an optical path from the light source S are provided. According to instructing information from a personal computer to the printer device, a printer control part 7 is operated, a character or a graphic is printed on the screen 6 by a printing head 8. At this time, the printing head 8 vertically scans a paper surface, so that the printing head 8 and the objective lens 1 are interlocked, thereby, both members can be synchronously scanned on the screen 6. |
