Abstract
In a camera body there are provided a light source, information carrying discs illuminated by the light source, and a half-mirror for dividing the light from the information carrying discs into a light beam directed to the viewfinder and a light beam directed to the film. In the optical path of the light beam directed to the film is provided a light shielding shutter blade to prevent the light from reaching the film when the information is not desired to be recorded on the film. The information carying discs are rotatably mounted in the camera body and carry various characters to be recorded on the film. The information carrying discs are manually operable from outside of the camera body by manually operable dials. The dials are protected from being accidentally moved by a cover. A switch operating pin is operated by the cover so that the light source is turned on when the cover is opened and the light source is momentarily turned on to record the information on the film upon release of the shutter mechanism in the camera when the cover is closed.
