Abstract

Abstract An accessory for use in vertical or horizontal copy cameras to optically reverse the image of an original. A frame of the accessory is insertable into the housing of a copy camera between the lens and the easel for originals and carries a mirror which makes with the optical axis of the lens an angle of 45*. The frame further carries a second easel which can be placed in front of the mirror so that it is located at 90* to the easel of the camera. The image of an original which is placed onto the second easel is reversed so that the camera can make right reading negative or positive copies.
