Abstract
A self reversing drive mechanism is disclosed for providing a reversible speed reducing drive between a drive shaft and the rotary tuner mechanism of a television receiver. The drive mechanism comprises an idler wheel freely pivotally mounted about the drive shaft and in engagement with it. The idler wheel has a circumference which is greater than the distance between the drive shaft and the driven member of the rotatable tuner. As a result, the idler wheel mechanism rotates about the drive shaft in either direction until itself engages with the driven member of the rotary tuner. This is done without any additional external forces to accomplish tight engagement of the idler wheel between the drive shaft and the driven member.
