Abstract

Abstract An electronic flash unit and a cartridge compartment for receiving an exchangeable film cartridge are disposed respectively at a forward part and a rear part of the inside space of a camera housing of a rectangular parallelepiped configuration which is thin in the upward and downward direction. An elongate cell compartment for receiving an electric cell for the electronic flash unit is also disposed within the camera housing between the cartridge compartment and the electronic flash unit at an oblique angle with respect to the forward and rearward direction. The cartridge compartment and the electronic flash unit are mutually separated in the forward and rearward direction such that the distance between the cartridge compartment and the electronic flash unit in the lateral direction is shorter than the width of the cell compartment.

Claim 3
Dependent Claim 175 words
A compact camera comprising a camera housing of substantially rectangular parallelopiped configuration with a relatively short forwardly rearwardly extending transverse axis and a relatively long laterally extending longitudinal axis, means defining a replaceable film cartridge holding compartment disposed in the rear portion of said camera housing, an electronic photoflash unit including a forwardly directed flash bulb located in said camera housing proximate a forward corner thereof, and elongate compartment means for replaceably housing a battery for energizing said photoflash unit, said camera being characterized by said film cartridge compartment means and said photoflash unit having their proximate edges laterally separated a distance less than the width of said battery compartment means and being transversely separated to delineate an opening, said battery compartment means extending from the rear portion toward the front portion of said housing through said opening at an oblique angle to said transverse and longitudinal axes, said proximate edges of said cartridge compartment means and said photoflash unit being in engagement with said battery compartment means at spaced locations along said transverse axis.
Claim 4
Dependent Claim 175 words
A compact camera comprising a camera housing of substantially rectangular parallelopiped configuration with a relatively short forwardly rearwardly extending transverse axis and a relatively long laterally extending longitudinal axis, means defining a replaceable film cartridge holding compartment disposed in the rear portion of said camera housing, an electronic photoflash unit including a forwardly directed flash bulb located in said camera housing proximate a forward corner thereof, and elongate compartment means for replaceably housing a battery for energizing said photoflash unit, said camera being characterized by said film cartridge compartment means and said photoflash unit having their proximate edges laterally separated a distance less than the width of said battery compartment means and being transversely separated to delineate an opening, said battery compartment means extending from the rear portion toward the front portion of said housing through said opening at an oblique angle to said transverse and longitudinal axes, said proximate edges of said cartridge compartment means and said photoflash unit being in engagement with said battery compartment means at spaced locations along said transverse axis.
Claim 5
Dependent Claim 32 words
