Panoramic camera
First Claim
1. An improved panoramic camera of the type having lens means, a camera body which holds a roll of film, a handle assembly rotatably affixed to the camera body, a take-up reel, a slit assembly for masking an image on a roll of film when it has been placed in the camera body, and means for rotating the camera body while simultaneously passing the film past the slit to place a panoramic image on the film, wherein the improvement comprises:
- film transport means timed by driving the film take-up spool, said film transport means comprising means for driving the film take-up spool comprising a handle assembly including a battery-driven motor and motor switch means, said motor having an output shaft affixed to said camera body, a handle pulley affixed to the handle and a spool pulley affixed to the take-up spool and a drive belt connecting the handle pulley and the take-up spool pulley whereby when the motor switch means is turned on, the motor shaft rotates the camera body while the take-up spool is turned by the drive belt so that the film is drawn past the slit at a speed so that the image moves at the same rate as the film producing a sharp panoramic image on the film.

Abstract
An improved panoramic camera of the type having a camera which turns as the film is drawn therethrough. The improved panoramic camera has a handle which contains a drive motor. A pulley is located on the handle and also on the base of the take-up spool. As the motor turns the camera, the belt between the two pulleys turns the take-up spool pulling the film past the slit in the camera in a timed manner.

9. An improved panoramic camera of the type having lens means, a camera body which holds a roll of film, a handle assembly rotatably affixed to the camera body, a take-up reel, a slit assembly for masking an image on a roll of film when it has been placed in the camera body, and means for rotating the camera body while simultaneously passing the film past the slit to place a panoramic image on the film, wherein the improvement comprises:
film transport means timed by driving the film take-up spool, said film transport means comprising means for driving the film take-up spool comprising said handle assembly including a motor and motor switch means, said motor having an output shaft affixed to said camera body, a handle pulley affixed to the handle and a spool pulley affixed to the take-up spool and a drive belt connecting the handle pulley and the take-up spool pulley and a film backup roller comprising a roller positioned so that its axis of rotation is parallel to the slit of the slit assembly and its outer surface is spaced from said slit a distance just sufficient so that the film can pass between the film backup roller and the slit, and wherein the film backup roller has drag means so that it has no tendency to coast whereby when the motor switch means is turned on, the motor shaft rotates the camera body while the take-up spool is turned by the drive belt so that the film is drawn past the slit at a speed so that the image moves at the same rate as the film producing a sharp panoramic image on the film. - View Dependent Claims (10, 11, 12, 13, 14)

15. A panoramic camera for taking a photograph over a wide angle by rotating while the photograph is being taken, said camera comprising:
-
a camera body including means for attaching a lens assembly and including a hinged back cover; a slit assembly held by said camera body, said slit assembly including a vertical slit positioned near the focal point of the lens which is affixable to the camera body; a handle assembly including a battery-driven motor and a motor switch, said motor having an output shaft which is affixed to the camera body; a handle pulley affixed to the handle assembly at the upper end thereof; a film take-up reel supported by the camera body and having a take-up pulley affixed thereto, said take-up pulley being located below the camera body and aligned with the handle pulley; a drive belt affixed between the take-up pulley and the handle pulley; means for holding a film spool in said camera body; and a film backup roller held by said hinged back cover of said camera body, said film backup roller being positioned so that its axis of rotation is parallel to said vertical slit of said slit assembly, and said backup roller having a smooth cylindrical outer surface, and said backup roller being aligned so that its surface is spaced behind said vertical slit a distance so that the film may pass between the slit and the backup roller, and said backup roller having a slight drag against turning.
