ABSTRACT:
An optical data recording device is mounted in a lens-fitted photographic film unit with a built-in flash device. The optical data recording device is provided for optically recording a number of dots on the photographic film, as print format data for designating a print format of photo-prints to be made from a picture frame of a constant size. A light source of the optical data recording device is mounted to a printed circuit board of the flash device so as to be supplied with a battery of the flash device and to be driven in synchronism with a shutter release operation. Light from the light source is transmitted through a light guide toward a plurality of openings which face the photographic film. The number of dots recorded per picture frame is changed by operating a format selection knob.
