Abstract
A framing mirror provided on the front part of a camera for enabling observation of the range of the scene to be photographed from the front of the camera is used for various displays by a liquid crystal display device. Various operation modes are set by a mode selection member and the state of the display portion of the liquid crystal display device arranged in front of the framing mirror changes in accordance with the set operation mode to effect various displays. In at least one of the operation modes the whole display portion of the liquid crystal display device becomes transparent, whereby it is possible to observe the framing mirror from the front of the camera. Alternatively, the framing mirror has a transparent portion at a marginal position and the liquid crystal display device is arranged behind the transparent portion so as to be observable from the front of the camera. The liquid crystal display device displays the same data as displayed by another liquid crystal display device which is arranged behind the framing mirror, for recording data on a photographic film.
