ABSTRACT:
An apparatus for inserting date information into given positions within the frames of film loaded in a camera. If it is impossible to modify the date, or if the user finds that the date is erroneous, the apparatus permits photographs with correct date to be printed. The apparatus has a CPU including a first RAM for storing the present date information. When frames of the film are used for photography, date information is inserted into the given positions, using a date information inserting LED array. When the present date information is modified by operating date switches, the difference between unmodified date information and modified date information is calculated and stored in a second RAM. The number of frames is also stored. When the film is rewound, the aforementioned difference and the number of frames are read out and inserted in the leader of the film. When the film used for photography in this way is printed, the date information, the difference, and the number of frames are checked. With respect to frames having frame numbers preceding the frame having a frame number equal to the above-described number of frames, i.e., frames used for photography before modification of the date information, the above-described difference is added to the date information. As a result, the frames can be printed with correct date information.
