  • Document shredder device
    Patent number: 8162248
    Abstract: A document shredder is provided with a transport system that holds and transports paper, and a shredding system that shreds the paper while rotating at a circumferential speed higher than a transporting speed of the transport system, wherein, a part of elements constituting the transport system is in common with a part of elements constituting the shredding system and a point of action of the transport system is placed substantially at the same position as a point of action of the shredding system, with respect to a paper transporting direction, and alternatively, the shredding system is arranged successively from the transport system. Since this shredder is assembled in such a manner that a part of elements constituting the transport system to hold and transport the paper is in common with a part of elements constituting the shredding system, it is possible to be downsized.
