Abstract
The multispeed drive mechanism is a clutchless drive mechanism including a rotatable input shaft and a plurality of input gears of different diameters mounted on the input shaft. A plurality of drive gears of different diameters are rotatably mounted on a support member and each engage one of the plurality of input gears. A driven member is driven at different speeds for the same speed of the input shaft by pivoting the support member about the input shaft and using different input gear/drive gear combinations to provide different gear ratios. The multiple speed drive mechanism is particularly useful for driving the movable platen of a copying apparatus at different speeds for reduction and enlargement copying.
