Abstract
A data imprinting device for a camera is provided with a light shielding system that shields part of light incident on an imaging frame of a film when the frame is exposed to light from an object to form a data imprinting area which is an unexposed area in the imaging frame. The data imprinting device is further provided with a data imprinting system that forms an optical image of data, such as photographing data, on the data imprinting area in a form of an encoded symbol, such as a bar code.
