Metering roll film holders and multi-format camera

A pair of roll film holders adapted for use with a multi-format camera for taking different size pictures on separate rolls of similar length film, wherein said film holders are of the type having respective frames with substantially similar dimensions for carrying the similar length rolls, means on each of said frames for supporting a roll of unexposed film, and rotatable means on each of said frames for taking-up successive portions of film exposed in a focal plane in the camera, and wherein the improvement comprises:

• first metering means corresponding to one picture size, said first means being positioned on one of said frames for advancing roll film on that frame in first length increments between exposures to provide a first number of exposures on the roll;
• and
• second metering means corresponding to another picture size, said second means being positioned on the other frame for advancing roll film on that frame in second length increments between exposures to provide a second number of exposures on the roll.

• metering rollers supported for rotation on said frames to advance exposed film to each of said rotatable take-up means;
• and
• metering gear assemblies coupled with said metering rollers to rotate each of the rollers at a slower speed than said individual take-up means to tension the film, said gear assemblies including respective metering gears having different numbers of teeth for rotating said metering rollers at different speeds to advance the film in different length increments corresponding to different picture sizes.
