Abstract

PURPOSE: To conduct the document shredding treatment at a high speed and in a continuous manner by rotating shredding blades by a motor, detecting the load current of the motor, and operating a means for protecting the shredding blades when the load current becomes a prescribed value or more. CONSTITUTION: Shredding blades 4, 5 are subjected to rotary driving together with a paper feeding roller 9 by a motor 6 to conduct the shredding treatment of waste documents 2. Before the shredding blades 4, 5 are deteriorated by the shredding treatment, the load current of the motor 6 is detected, and at a time point when it becomes a prescribed value or more, a blower 12 is driven to blow air for cooling the shredding blades 4, 5 and protect the shredding blades 4, 5. Instead of the cooling wind, cooling liquid may be used.
