发明名称 Method of photographing on microfilm and apparatus therefor
摘要 A method and apparatus for photographing images on a microfilm from a manuscript placed on a table together with additional information is arranged such that a photographing position for the manuscript is displaced from that for the additional information structurally. A format of blip marks, a frame size, and a counting system of the additional information are preset and the presetting of the frame size is effected with an actuation of a mask plate. The size of the additional information on the microfilm is made selectable between discrete values in accordance with the magnification of the manuscript. The photographing of the manuscript and the additional information is then effected in a chronological order.
