Lens-fitted photo film unit and photofinishing method

#1. Field of the Invention

#The present invention relates to a lens-fitted photo film unit and a photofinishing method. More particularly, the present invention relates to a lens-fitted photo film unit in which information is photographically recorded for each of imaging frames and which has a simplified structure, and a photofinishing method for producing photographic prints by use of the information.

#2. Description Related to the Prior Art

#The above objects and advantages of the present invention will become more apparent from the following detailed description when read in connection with the accompanying drawings, in which:

#FIG. 1 is a perspective illustrating a lens-fitted photo film unit;

#FIG. 2 is an exploded perspective illustrating the lens-fitted photo film unit;

#In FIG. 1, a lens-fitted photo film unit 2 is illustrated. A front side of the lens-fitted photo film unit 2 includes a taking lens 3, an objective window 4, a flash emitter 5, a flash charger button 6 and a selector button 7. An upper side of the lens-fitted photo film unit 2 has a shutter release button 8, a frame counter window 9 and a light guide 10. A rear side of the lens-fitted photo film unit 2 is has a winder wheel 11 and an eyepiece window 12 partially uncovered externally. For the eyepiece window 12, see FIG. 2.

#The selector button 7 is slidable on a front face of the lens-fitted photo film unit 2 in its longitudinal direction. The selector button 7 is slidable between the standard position and telephoto position. When the selector button 7 is in the standard position, the magnification of the viewfinder is equal to that according to the conventional lens-fitted photo film unit, to obtain a photographic print of the C size from the photographic paper. When the selector button 7 is in the telephoto position, the magnification of the viewfinder is 1.63 times as high as that according to the standard position, to obtain a photographic print in enlargement at the C size from the photographic paper.

#In FIG. 2, the lens-fitted photo film unit 2 includes a front cover 15, a main body 16, an exposure unit 17, a flash unit 18 and a rear cover 19. There are a cassette holder chamber 20 and a roll holder chamber 21 disposed respectively at ends of the main body 16. A photo film cassette 22 of the IX240 type is inserted in the cassette holder chamber 20. A photo film 23 is drawn from the photo film cassette 22 and wound as a photo film roll 23a, which is inserted in the roll holder chamber 21.
