A photographic cassette with an automatic photographic labeling device comprises an LCD panel (12) and a power supply unit (14) connected to the body of cassette (18). The LCD panel consists of unit display cells (26) arranged in a checkerboard pattern and connected in parallel to the power supply unit, so that any portion of the displaay panel can be removed without damaging the electric connection between the power supply unit and the remaining display cells (26). The cassette with the panel attached is installed into a photographic camera as with a conventional cassette. Since the remaining display cells are constantly connected to power supply unit, which in turn is connected to a crystal timing element (22), the display elements constantly display time indicia, i.e., the year, month, day, etc. When a picture is taken, the non-transparent time delay indicia are projected onto the film and are produced after development. An embodiment of an instant-type camera is characterized by using the batteries, which are available in the cassette for such cameras for driving the film operating mechanism, and which are used here for driving the timing mechanism of the unit. Since the unit is sealed and is provided with unit identification data, it can be used as legal proof of the time when the picture was taken.
