Abstract
Abstract A single use camera is preloaded with a roll of magnetically coated film with defined image frames. The camera has an exposure system for selectively exposing an image frame of the film in one of a plurality of image formats. The camera also includes a manually actuated mechanism coupled to a mounted permanent magnet. The magnet is movable to record a magnetic mark on the magnetically coated film at a predetermined location relative to an exposed image frame. The location of the mark is indicative of the image format of the exposed image frame.

Claims Analysis
Total Claims: 4
Claim 1
Independent Claim
156 words
A single use camera comprising: a light tight housing; a roll of magnetically coated film with defined image frames, preloaded in said housing; a movably mounted permanent magnet normally out of contact with said film; an exposure system for selectively exposing an image frame of said film in one of a plurality of image formats, said exposure system including a manually actuatable exposure member; a manually actuatable format selection mechanism coupled to said permanent magnet for moving said permanent magnet to a position to record a magnetic mark on said magnetically coated film at a predetermined location relative to an exposed image frame, said location of said mark being indicative of the image format of said exposed image frame; and a linkage linking said exposure member with said permanent magnet, such that manual actuation of said exposure member causes said permanent magnet to contact said film to record a magnetic mark in said magnetically coated film.
Claim 2
Dependent Claim

A single use camera comprising: a light tight housing; a roll of magnetically coated film with defined image frames, preloaded in said housing; a movably mounted permanent magnet normally out of contact with said film; an exposure system for selectively exposing an image frame of said film in one of a plurality of image formats, said exposure system including a manually actuatable exposure member; a manually actuatable format selection mechanism coupled to said permanent magnet for moving said permanent magnet to a position to record a magnetic mark on said magnetically coated film at a predetermined location relative to an exposed image frame, said location of said mark being indicative of the image format of said exposed image frame; and a linkage linking said exposure member with said permanent magnet, such that manual actuation of said exposure member causes said permanent magnet to contact said film to record a magnetic mark in said magnetically coated film.
Claim 3
Dependent Claim
161 words
A single use camera comprising: a light tight housing; a roll of magnetically coated film with defined image frames, preloaded in said housing; a plurality of prerecorded magnetic marks at different locations along an image frame, one each for each of a plurality of image formats; a movably mounted permanent magnet normally out of contact with said film; an exposure system for selectively exposing an image frame of said film in one of a plurality of image formats, said exposure system including a manually actuatable exposure member; a manually actuatable format selection mechanism coupled to said permanent magnet for moving said permanent magnet to a position to erase all of said prerecorded marks except the said mark which is indicative of the image format of said exposed frame; and a linkage linking said exposure member with said permanent magnetic such that manual actuation of said exposure member causes said permanent magnet to contact said film to selectively erase said prerecorded marks.
