Flasher capable of varying a light distribution angle

A flasher for use in a camera with a variable field angle of coverage, comprising:

• a reflecting assemblage for receiving light emitted from a flash source and irradiating reflected light toward an object to be photographed wherein a distribution angle of the light that is irradiated toward said object is varied with a change in said field angle of coverage,
• said reflecting assemblage comprising a stationary reflecting mirror where a distribution angle of the light reflected toward said object is constant, said stationary reflecting mirror having an upper portion, lower portion and depth portion with a reflecting surface positioned in the upper portion, lower portion and depth portion,
• a movable reflecting mirror having an upper reflector plate disposed above said stationary mirror and a separate lower reflector plate disposed below said stationary mirror, each of said upper and lower reflector plates being separate from the stationary reflecting mirror, wherein the upper and lower reflector plates are interlocked and configured to rotate about an axis of said stationary mirror, where a distribution angle of the light reflected toward said object is variable, and
• a drive mechanism for driving said movable reflecting mirror in interlock with a change in said field angle of coverage.

A flasher for use in a camera with varifocal photographic lenses comprising:

• a reflecting assemblage for receiving light emitted from a flash source and irradiating reflected light toward an object to be photographed wherein a distribution angle of the light that is irradiated toward said object is varied with a change in focal length of said varifocal photographic lens,
• said reflecting assemblage comprising a stationary reflecting mirror where a distribution angle of the light reflected toward said object is constant, said stationary reflecting mirror having an upper portion, lower portion and depth portion with a reflecting surface positioned in the upper portion, lower portion and depth portion,
• a movable reflecting mirror having an upper reflector plate disposed above said stationary mirror and a separate lower reflector plate disposed below said stationary mirror, each of said upper and lower reflector plates being separate from the stationary reflecting mirror, wherein said upper and lower reflector plates are interlocked and configured to rotate about an axis of said stationary mirror, where a distribution angle of the light reflected toward said object is variable, and
• a drive mechanism for driving said movable reflecting mirror in interlock with a change in said focal length.

A flasher for use in a camera with varifocal photographic lenses having a variable distribution angle of flashed light, the flasher comprising:

• a flash discharge tube which has a cylindrical contour;
• a stationary reflecting umbrella for reflecting light emitted from said flash discharge tube and emitting the reflected light from an opening formed forwards toward an object to be photographed, said stationary reflecting umbrella having an upper portion, lower portion and depth portion with a reflecting surface positioned in the upper portion, lower portion and depth portion;
• and
• an upper reflector plate and a separate lower reflector plate, both the upper and lower reflector plates being separate from the stationary reflecting umbrella with the upper reflector plate being disposed above and in front of said opening, and the lower reflector plate being disposed below and in front of said opening, the upper and lower reflector plates receiving part of the light emitted from said opening and being interlocked and rotatable about an axis of the stationary reflecting umbrella with a change in focal length of said photographic lens so that a distribution angle of the reflected light emitted to said object is varied.

A flasher for use in a camera with varifocal photographic lenses having a variable distribution angle of flashed light, the flasher comprising:

• a flash discharge tube which has a cylindrical contour;
• a stationary reflecting umbrella having an upper portion, lower portion and depth portion with a reflecting surface positioned in the upper portion, lower portion and depth portion, wherein said flash discharge tube is positioned in said depth portion thereof and which emits light emitted from said flash discharge tube from a rectangular opening toward an object to be photographed and also reflects the light emitted from said flash discharge tube to emit the reflected light from said rectangular opening toward said object, the rectangular opening being formed at a front of said stationary reflecting umbrella and having a long edge portion positioned in parallel with a longitudinal direction of said flash discharge tube;
• an upper reflector plate and a separate lower reflector plate each of which is separate from the stationary reflecting umbrella and has a rectangular shape, a long edge portion of the upper reflector plate being disposed near a front upper edge portion of said opening, a long edge portion of the lower reflector plate being disposed near a front lower edge portion of said opening, the upper and lower reflector plates receiving part of the light emitted from said opening and being pivoted on a shaft in parallel with a long edge of said rectangular shape in opposite directions in interlock with a change in focal length of said photographic lens so that a direction of the reflected light emitted to said object is varied;
• and
• a frame structure which has shaft support holes for rotatably supporting respective rotational axes of said upper and lower reflector plates and also has a wall portion to which a bottom portion of the stationary reflecting umbrella abuts and is fixed, said flash discharge tube and said stationary reflecting umbrella being fixed to said frame structure, and said upper and lower reflecting plates being pivotably supported by said frame structure.
