Data imprinting device for a camera

A data imprinting device for a camera comprising:

• means for selecting a chosen mode of a first and a second screen size mode;
• a light source mounted in a body of said camera;
• means for driving said light source responsive to a movement of a film;
• a first optical member for focusing light from said light source upon said film at a first location, when said first screen size mode is selected, whereby an image is imprinted upon said film at said first location;
• a second optical member for focusing light from said light source upon said film at a second location, when said second screen size mode is selected, whereby an image is imprinted upon said film at said second location;
• bracket means for coupling said first and second optical members in a fixed relationship to each other;
• and
• said bracket means being mounted in said body of said camera such that said first and second optical members focus said light source upon said film.
