PURPOSE:To execute a conversion of a projecting magnification by a very simple mechanism by selecting and using one of plural focusing transmitting bodies which are different in a magnification of an image on an image forming face. CONSTITUTION:An original D is scanned in the direction as indicated with an arrow, and focusing optical transmitting bodies 1, 2 of an array lens or a SELFOC lens, etc. are provided so as to be movable as one body. These optical transmitting bodie 1, 2 are different in its projecting magnification, the part other than a divided area x1 of the original D is covered with shielding members 3a, 3b, and a light of the transmitting body which is not used is prevented. The using area x1 of the transmitting body 1 whose projecting magnification is large is projected as an image y1 onto a photosensitive body P. The projecting magnification is shown by y1/x1. When the small projecting magnification is used, the transmitting body 2 is positioned in the area x1. In this case, the area x1 is projected as an image y2 onto the photosensitive body P. The projecting magnification is shown by y2/x1. |
