PURPOSE:To miniaturize a device on the whole by providing a slit part between a subject and a film, by moving this slit part, and thus by using a linear light source as a copying light source. CONSTITUTION:A light shielding case 41 having a linear slit part 41a on a document is moved at right angles to the slit part 41a by driving a wheel 32. At this time, linear information 1a is lit up by an illumination light source 31 and a real image 3a is formed on a film 4 through a lens 2. According to the movement of the case 41, the film 4 moves, so exposure corresponding to the plane of the document is obtained on the film surface. As the light source, long-sized one corresponding to the width of the slit part 41a is preferably used. Consequently, the part requiring illumination is linear and small in area. |
