Abstract
Data such as the place and time a picture is taken are written on a tape in a data capsule which is detachably mounted in the camera body. A light source and an optical system are mounted in a hollow tube which is movable along the tape to scan the data and project the data onto an edge portion of the film when the camera shutter is opened. The tube has an aperture facing the film surface and another aperture facing the tape through which the image of the data passes. The aperture facing the tape is arranged very close to the surface of the tape so that light from the light source is prevented from being scattered into the body of the camera and adversely affecting the film.
