Abstract
Abstract A compact camera which includes an auto focus mechanism arranged above a shutter aperture between a film cartridge chamber and a film spool chamber at the same height above the light axis center as a strobe mechanism mounted above the spool chamber. A film winding and shutter charge gear is mounted above the film cartridge chamber and a film winding gear mounted between spool chamber and strobe mechanism. Gear transmission means are mounted between said gears and between an aperture and an auto focus mechanism, and serve for interlocking rotation of the gears.

Claims Analysis
Total Claims: 5
Claim 1
Independent Claim
203 words
A compact camera including a housing carrying an image transmitting aperture having a light-axis center, said camera comprising: an auto focus mechanism positioned above the aperture; a film cartridge chamber and a film spool chamber disposed on opposite sides of the aperture; a strobe mechanism mounted above the film spool chamber, said auto focus mechanism positioned between the film cartridge chamber and the spool chamber, and having an upper surface at substantially the same height above the light axis center as an upper surface of the strobe mechanism; film winding and shutter charge gear means mounted above the film cartridge, and a film winding gear means mounted between the film spool chamber and the strobe mechanism; and transmission means extending between and interconnecting each of said gear means and positioned between the aperture and the auto focus mechanism for interlocking the rotation of said respective gear means, said transmission means comprising a first transmission gear meshing with and extending downwardly from the film winding and shutter charge gear means toward the light-axis center, a second transmission gear meshing with and extending downwardly from the film winding gear means toward the light-axis center, and interconnecting means for interconnecting the first and second transmission gears.
Claim 2
Dependent Claim
203 words
A compact camera including a housing carrying an image transmitting aperture having a light-axis center, said camera comprising: an auto focus mechanism positioned above the aperture; a film cartridge chamber and a film spool chamber disposed on opposite sides of the aperture; a strobe mechanism mounted above the film spool chamber, said auto focus mechanism positioned between the film cartridge chamber and the spool chamber, and having an upper surface at substantially the same height above the light axis center as an upper surface of the strobe mechanism; film winding and shutter charge gear means mounted above the film cartridge, and a film winding gear means mounted between the film spool chamber and the strobe mechanism; and transmission means extending between and interconnecting each of said gear means and positioned between the aperture and the auto focus mechanism for interlocking the rotation of said respective gear means, said transmission means comprising a first transmission gear meshing with and extending downwardly from the film winding and shutter charge gear means toward the light-axis center, a second transmission gear meshing with and extending downwardly from the film winding gear means toward the light-axis center, and interconnecting means for interconnecting the first and second transmission gears.
Claim 3
Dependent Claim
17 words
A compact camera as claimed in claim 1, in which said interconnecting means includes a gear train.
Claim 4
Dependent Claim
22 words
A compact camera as claimed in claim 1, wherein the number of teeth on each of the transmission gears is the same.
Claim 5
Dependent Claim
53 words
A compact camera as claimed in claim 1, in which the housing has a top and a bottom and the height of the top of the housing above the light-axis center is substantially equal to the sum of one-half the height of the film spool chamber and the height of the strobe mechanism.
