Abstract
A single-motor shredder has a housing, and multiple cutting rollers, a paper feeding mechanism and a motor mounted in the housing. A first gear set connects the cutting rollers with the motor and a second gear set connects the cutting rollers with the paper feeding mechanism. Only one motor is needed to drive the cutting rollers and the paper feeding mechanism. Therefore, the shredder is light and a manufacturing costs of the shredder are lowered. Moreover, the paper feeding mechanism separates a stack of paper into small piles to sequentially feed the stack of paper in small piles. Thus, the stack of paper does not jam the cutting rollersso improving lifetime of the shredder.
