Pressure member urging mechanism

Mechanism for urging a pressure member against a photographic film to locate an exposure area of the film in an exposure plane, said mechanism comprising:

• a strip member having first and second portions spaced from each other and a bowable urging portion between said first and second portions, said strip member being adjustable to a normal configuration in which said first and second portions are separated by a given distance at which said urging portion is substantially flat and an urging configuration in which said first and second portions are separated by a lesser distance at which said urging portion is bowed toward the exposure plane to urge the pressure member against the film;
• and
• means for engaging said first portion and moving it toward said second portion to reduce the spacing between said two portions for adjusting said strip member from said normal configuration to said urging configuration.

Mechanism for urging a pressure member against a photographic film to locate an exposure area of the film in an exposure plane, said mechanism comprising:

• a strip member having first and second substantially flat portions disposed in a storage plane in spaced relation and a bowable urging portion between said first and second portions;
• and
• means moving said first portion in the storage plane toward said second portion for bowing said urging portion toward the exposure plane to urge the pressure member against the film.

Mechanism for urging a pressure member against a photographic film to locate an exposure area of the film in an exposure plane, said mechanism comprising:

• a strip member having first and second substantially flat portions disposed in a storage plane in spaced relation and a resilient bowable urging portion between said first and second portions and which, when bowed, tends to straighten;
• means for constraining said first and second portions in the storage plane;
• means for moving said first portion in the storage plane toward said second portion, for bowing said urging portion toward the exposure plane to urge the pressure member against the film, and for releasing said urging portion to move said first portion in the storage plane away from said second portion by straightening .
