Abstract
PURPOSE:To easily obtain a clear copy without distortion or eclipse by providing a lens-moving means that moves a lens back-and-forth based on distance data obtained by a range finding means for focussing and that, at the same time, shifts the lens corresponding the distance data. CONSTITUTION:When supplied power to an auto-focussing (AF) unit 8, it captures an image on the surface of a blackboard, and measure the distance from a line sensor 40 to the blackboard surface. A motor 78 is driven based on thus obtained distance data to rotate a junction bar 77 so that the lens 6 is moved along slits 71-73. The lens 6, as maintaining a right angle between its own optical axis and the line sensor 40, moves to such a position to form the image on the blackboard on the line sensor 40 and stops therein. Since the lens 6 is moved along the curve of slits 71-73, the most suitable amount of shifting is determined at the moment when the lens 6 stops in the focussing position. As a result, distortion or eclipse can be automatically corrected.
