Exposure-adjusting system for still or motion-picture cameras

Claim 2

A camera adapted to be loaded with a film container provided with coding means for indicating the sensitivity of film contained therein, said camera comprising in combination: a. an exposure control apparatus adjustable to produce different exposures of film in said camera, b. code-sensing means positionable by such coding means of a film container loaded into said camera to automatically adjust said exposure control apparatus as a function of the film sensitivity characterized by such coding means, c. manually operable exposure regulating means movable 1. to a first position to permit such automatic adjustment of said exposure control apparatus to be effected by said codesensing means and 2. to any of a plurality of second positions to effect corresponding adjustments of said exposure control system independently of said code sensing means, and d. signal means for producing a signal in response to said camera being loaded with a film container devoid of such coding means, and e. means responsive to the loading of a film container therein for moving said manually operable exposure regulating means to said first position thereof.

Claim 3

to any of a plurality of second positions to effect corresponding adjustments of said exposure control system independently of said code sensing means, and d. signal means for producing a signal in response to said camera being loaded with a film container devoid of such coding means, and e. means responsive to the loading of a film container therein for moving said manually operable exposure regulating means to said first position thereof.

Claim 4

to any of a plurality of second positions to effect corresponding adjustments of said exposure control system independently of said code sensing means, and d. signal means for producing a signal in response to said camera being loaded with a film container devoid of such coding means, and e. means responsive to the loading of a film container therein for moving said manually operable exposure regulating means to said first position thereof.

Claim 5

A camera adapted to be loaded with a film container provided with tactile code indicia positioned to indicate the sensitivity of film in the container, said camera comprising: a. an exposure control apparatus adjustable to produce different exposures of film in the camera; b. code-sensing means including a member having at least two projections engageable with the code indicia of such a film container loaded in the camera for translatably and rotatably positioning the member as a function of the film sensitivity characterized by the code indicia; c. means for automatically adjusting said exposure control apparatus in response to movement of said code-snesing member; d. means associated with said code-sensing means for producing a signal indicative of the presence or absence of such code indicia on such a cartridge loaded in the camera; and e. alternative exposure regulating means manually movable to a first position to permit automatic adjustment of the exposure control member by the code sensing means, and to any of a plurality of second positions to effect corresponding adjustment of said exposure control system independently of said code-sensing means.

Claim 6

A camera adapted to be loaded with a film container provided with tactile code indicia positioned to indicate the sensitivity of film in the container, said camera comprising: a. an exposure control apparatus adjustable to produce different exposures of film in the camera; b. code-sensing means including a member having at least two projections engageable with the code indicia of such a film container loaded in the camera for translatably and rotatably positioning the member as a function of the film sensitivity characterized by the code indicia; c. means for automatically adjusting said exposure control apparatus in response to movement of said code-snesing member; d. means associated with said code-sensing means for producing a signal indicative of the presence or absence of such code indicia on such a cartridge loaded in the camera; and e. alternative exposure regulating means manually movable to a first position to permit automatic adjustment of the exposure control member by the code sensing means, and to any of a plurality of second positions to effect corresponding adjustment of said exposure control system independently of said code-sensing means.
