Claims

[Scope of utility model registration request]

a pair of transport rotors rotatably supported in proximity to a shredded paper supply port formed in the main body; a plurality of circumferential grooves recessed in the axial direction of the transport rotors at shredding width pitches; a rotational drive device for the conveying rotary body; first and second fixed blades arranged in each of the circumferential grooves so as to have blade surfaces at an acute angle with respect to the direction in which shredded paper is conveyed by the pair of conveying rotary bodies; an attachment device for attaching the first and second fixed blades to the main body, and the first and second fixed blades are arranged one by one or a plurality of blades alternately so that the acute angles of the blade surfaces are opposite to each other. A shredding device for a document shredding machine, characterized in that a fixed blade unit is integrally fixed to a support.
