摘要： A high speed, high resolution, continuous optical film printer (25) is disclosed for copying negative intermediate film (11) onto a print film (12). The two films are placed side by side on a common transport shaft (13) and moved past an illumination system comprised of a source (30) and an integrating cylinder (15a). A unit magnification imaging optical system (25) produces a telecentric, monocentric, color corrected, high resolution, low flare image strip (18) on the print film which is parallel to the object strip. The optical film print also provides angularly diffuse illumination to provide scratch and matte suppression.

摘要： A driving mechanism such as a Geneva Mechanism which allows a load, such as film in a motion picture projector, to be intermittently advanced with controlled acceleration. The Geneva Mechanism includes a star wheel and a rotating driver. The star wheel includes slots and is operationally associated with the load. The rotating driver includes a drive pin which cooperates with the slots to cause an intermittent rotation of the star wheel. Either the slots or the drive pin is shaped in a controlled manner to permit optimum acceleration and deceleration of the star wheel.

摘要： A high speed multi-magnification photofinishing printer for selectively projecting images onto a projection plane containing photographic paper at a plurality of different magnifications is disclosed herein. This printer includes means for supporting a given image bearing photographic negative, means cooperating with the negative for producing a given image bearing light beam, and a plurality of spaced apart but fixed magnification lenses, each of which is designed to project the given image bearing light beam onto the photographic paper contained within the projection plane at different magnifications. The printer also includes light beam position altering means for selectively and alternatively causing the image bearing light beam to pass through any one of the plurality of fixed magnification lenses and onto the photographic paper, whereby to selectively and alternatively project the image bearing light beam onto the paper at one of the different magnifications. As disclosed, this light beam position altering means is comprised of an array of planar mirrors fixedly mounted on a movable carriage in a particular way.
