Abstract
Photographic apparatus having an optical system which in a first mode of operation functions to image a subject upon a film plane so as to be geometrically reversed along only one axis of the film plane and in a second mode of operation functions to image the subject on the film plane so as to be geometrically reversed along each of two orthogonal axes, the particular mode being dependent upon the type of film unit being exposed.
Claims5
Photographic apparatus of the self-developing type for use with film units requiring an even number of geometrical reversals and with film units requiring an odd number of geometrical reversals to provide a geometrically non-reversed positive image in the film unit, comprising:
- means for locating a film unit in position for exposure;
- pressure-applying means including at least two juxtaposed members for spreading a processing fluid across a photosensitive layer of the film unit as it is moved therebetween subsequent to exposure;
- lens means for geometrically reversing an image of a subject along two orthogonal axes;
- optical means for geometrically reversing the image of the subject along only one of said orthogonal axes;
- means for changing the relative position of said lens means and said optical means between a first orientation wherein said lens means and said optical means are in optical alignment with each other when the film unit requires an odd number of geometrical reversals and a second orientation wherein said lens means and said optical means are out of optical alignment with each other when the film unit requires an even number of geometrical reversals;
- and
- means coupled to said changing means and responsive to the loading of a cassette containing a film unit of the type requiring an even number of reversals for automatically moving said optical means from said first orientation to said second orientation.
