Abstract
A lens-fitted photo film unit includes a shutter for providing photo film with an exposure to create a frame. A flash circuit emits flash light to a subject to be photographed. The flash circuit includes a blocking oscillator for converting low voltage of a battery into high voltage of an alternate current by oscillation. An optical data recorder device includes a timer circuit, which starts in response to actuation of the shutter operation. The timer circuit measures predetermined time of lapse, and starts the oscillation of the blocking oscillator. A light-emitting element illuminates with voltage obtained from the blocking oscillator during the predetermined time measured by the timer circuit. Data is recorded optically in a position on the photo film respectively for the frame.
