Data recording means for use in a single lens reflex camera

摘要

Data recording for a single lens reflex camera which comprises a data carrier assembly which carries at least two identical sets of data, a constant positional relationship being maintained between corresponding data items in the two sets. In any setting of the data carrier assembly a data item in one set is brought to a recording position from which the image of the data item is directed onto film material when the camera shutter is actuated, and the corresponding data item in the other set is brought to a viewing position from which the image thereof is constantly transmitted to the viewfinder eye-lens.
