を特徴とする板書面複写装置。 a slit illumination unit that illuminates the board document in a slit shape; a first imaging optical system including an imaging lens and a reflecting member that projects the board document onto the photoreceptor in a slit shape; and a first imaging optical system that projects the document image for copying onto the photoreceptor. The first imaging optical system that forms an image in a slit shape is equipped with a second imaging optical system that is partially shared or separate from the first imaging optical system, and both the image information written on the board and the original for copying are handled by the optical system. 1. A board document copying apparatus, wherein an image forming apparatus capable of selectively copying is provided with a slit member near the optical path of the first imaging optical system for regulating the width of a light beam incident on the imaging lens.
