Lens-fitted photographic film package

A lens-fitted photographic film package containing an unexposed photographic film and mechanism for exposing said film, said lens-fitted photographic film package further comprising:

• a taking lens system including at least two lenses;
• and
• a spacing member disposed between two adjacent said lenses for maintaining the spacing between said two lenses, said spacing member having an aperture therethrough;
• said shutter comprising:
• an actuating lever which is released by release means;
• a V-shaped blade of which one end is pivoted and the other end slides on a recessed surface of said spacing member so as to open and close said aperture;
• and
• a connecting lever swinging on the side of said V-shaped blade opposite said spacing member, one end of said connecting lever being engaged with an elbow of said V-shaped blade, whereas the other end of said connecting lever is struck by said actuating lever when said actuating lever is released, said connecting lever at least partially overlapping said V-shaped blade in an area from said elbow to said one end of said V-shaped blade when said connecting lever is swung to move said V-shaped blade so as to open and close said aperture.

A lens-fitted photographic film package comprising means defining a film supply chamber and a film take-up chamber, an unexposed photographic film rolled up in said film supply chamber and means to wind said film from said film supply chamber to said film take-up chamber, said lens-fitted photographic film package further comprising:

• means defining an exposure chamber between said film supply chamber and a film take-up chamber, said exposure chamber having in a rear side thereof a first rectangular opening for defining an exposure area of said film;
• a taking lens system disposed in front of said exposure chamber;
• and
• a light-shielding member mounted inside said exposure chamber, said light-shielding member having a second rectangular opening forward of said first rectangular opening and through which only necessary exposure light from said taking lens system travels toward said first opening.

A lens-fitted photographic film package containing an unexposed photographic film and mechanism for exposing said film, said lens-fitted photographic film package further comprising:

• a taking lens system including at least two lenses;
• a shutter disposed between the lenses;
• a spacing member disposed between two adjacent said lenses for maintaining a predetermined spacing between said two lenses;
• there being an aperture extending through said spacing member, said aperture being disposed on the optical axis of said taking lenses and being adapted to be opened and closed by said shutter;
• said spacing member having a recessed surface about said aperture, and said shutter sliding on said recessed surface;
• said shutter comprising:
• said shutter comprising:
• release means;
• an actuating lever which is released by said release means;
• a V-shaped blade of which one end is pivoted and the other end slides on said recessed surface so as to open and close said aperture;
• and
• a connecting lever swingably mounted on the side of said V-shaped blade opposite said spacing member, one end of said connecting lever being engaged with an elbow of said V-shaped blade, whereas the other end of said connecting lever is struck by said actuating lever when said actuating lever is released, said connecting lever at least partially overlapping said V-shaped blade in an area from said elbow to said one end of said V-shaped blade when said connecting lever is swung to move said V-shaped blade so as to open and close said aperture.

A lens-fitted photographic film package containing an unexposed photographic film and mechanism for exposing said film, said lens-fitted photographic film package further comprising:

• a taking lens system including at least two lenses;
• a shutter disposed between the lenses;
• a one-piece spacing member disposed between two adjacent said lenses for maintaining a predetermined spacing between said two lenses;
• there being an aperture extending through said spacing member, said aperture being disposed on the optical axis of said taking lenses and being adapted to be opened and closed by said shutter;
• said spacing member having rib means defining a recessed surface about said aperture, and said shutter sliding on said recessed surface through a gap in said rib means.
