Abstract

A Brownie film is wound about a spool such that a leader covers outside. A filmstrip has first and second lateral side portions. Upon manufacturing the filmstrip, film information is printed as latent images in the first lateral side portion. The first lateral side portion comes to upper side of the filmstrip when the filmstrip is pulled from the spool to leftward, viewed from a base surface side of the filmstrip. A data exposure head of the camera imprints photographic information as individual printing patterns.

Claims

1. A Brownie film, wherein a filmstrip is wound about a spool, said filmstrip having first and second lateral side portions outside of photography frames, said Brownie film comprising:

a recorded printing patters printed only in said first lateral side portion, said printing patterns representing information regarding a film and printed upon manufacturing said film;

wherein individual printing patterns are imprinted in said second lateral portion upon photography;

wherein said recorded printing patterns, said individual printing patterns, and said photography frames are in erect right images, viewed from a base surface side of said perpendicular filmstrip when said first lateral side is upper side.

2. A Brownie film as defined in claim 1, wherein said first lateral side portion is upper side, viewed from a base surface side of said filmstrip when said filmstrip is pulled perpendicularly out leftward from said spool.

3. A Brownie film as defined in claim 2, wherein said information regarding to the film includes positional information recorded at a constant pitch.

4. A Brownie film as defined in claim 3, wherein said information regarding the film further includes photosensitivity and type of said film.

5. A Brownie film as defined in claim 4, wherein said first lateral side portion is within 2.5 mm from said first lateral side.

6. A Brownie film as defined in claim 5, wherein a pitch of said positional information is not less than 25 mm and not more than 45 mm.

7. A camera and loadable Brownie film,

wherein said Brownie film is a filmstrip, having first and second lateral side portions, which is wound about a spool,

wherein only said first lateral side portion has recorded printing patterns upon manufacturing of the film,

wherein individual printing patterns are imprinted in said second lateral portion upon photography;

and

wherein said camera comprises;

an exposure aperture for exposing said filmstrip to form a picture frame; and

a data imprinting head for imprinting said individual printing patterns representing information regarding said picture frame;

wherein said first and second lateral side portions are outside of said picture frame;

wherein said recorded printing patterns, said individual printing patterns, and said picture frame are in erect right images, viewed from a base surface side of perpendicular filmstrip when said first lateral side portion is upside.

8. A camera and loadable Brownie film as defined in claim 7,

wherein said first lateral side portion is positioned underneath said exposure aperture, said second lateral side portion is positioned above said exposure aperture; and said data imprinting head is disposed above said exposure aperture.

9. A camera and loadable Brownie film as defined in claim 8, wherein said first lateral side portion is upside, viewed from the base surface side of perpendicular filmstrip, when said filmstrip is pulled out leftward from said spool.

10. A camera and loadable Brownie film as defined in claim 9, wherein said individual printing patterns include code and total frame number that are specific for each camera.
