Geneva mechanism and motion picture projector using same |
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. |
