Abstract
An improvement of microfilm camera with a marking device in which an image of a document is photographed on a roll film mounted in a cassette using a slit exposure system and a two-dimensional digital image of a mark is recorded on the roll film. The microfilm camera comprises: an image taking lens for forming the image of the document on the roll film; a mark taking lens having an optical axis inclined in the length side direction of the roll film with respect to that of the image taking lens; and a digital image generator for generating a one-dimensional digital image extending in the width side direction of the roll film and formed by said mark taking lens at or in close vicinity of the image forming position of the image taking lens. The two-dimensional image of the mark is recorded on the film by changing the one-dimensional digital image synchronously with traveling of the film. With such construction, the size of a photographic opening provided in the cassette can be reduced to made the cassette structure simple. It is unnecessary to provide a complicated synchronizing mechanism for setting mark projecting or recording timing.
