Abstract: A lens-fitted photo film unit is preloaded with a roll of photo film whose film speed is ISO3200, and has a mode selection member that is manually operated to select one of a standard photography mode, an indoor photography mode and a night-view photography mode. In the standard photography mode, an exposure is made without flash with a small aperture size and at a high shutter speed. In the indoor photography mode, an exposure is made with a flashlight, with a middle aperture size and at a high shutter speed. In the night-view photography mode, an exposure is made with a flash light, with a large aperture size and at a low shutter speed.

Abstract: In a reproduction method for lens-fitted photo film units, a roll of high-speed photo film of ISO1600 or more is loaded in a new film unit body, so as to produce a lens-fitted photo film unit that is improved in imaging characteristics for a low brightness scene with regard to its background. After being used up, the high-speed film is unloaded for development, and the emptied film unit body is recovered for recycling. In a recycling line, a roll of standard-speed photo film of ISO400 is loaded in a reproduced film unit body, so as to be sold as another type lens-fitted photo film unit that is improved in imaging characteristics in a background area of a high brightness scene.

Abstract: During thermal recording and optical fixing of a sheet of thermosensitive recording paper, a leading end of the recording paper has been clamped by a clamp member for securing the recording paper to a platen drum. Thereafter, the clamp member is released, and the platen drum is rotated at a high speed to rapidly move the leading end to a bleaching position directly below the center of an ultraviolet lamp which is used for the optical fixing. The leading end is stopped in the bleaching position for a short time enough to bleach the leading end by the ultraviolet rays.
