Abstract
When a printing paper to which an IC chip storing secret information is attached is discarded, a shredder applied voltage to the IC chip by a discharging unit to destroy the IC chip and to make it impossible to read the secret information therefrom. Thereafter, a shredding cutter shreds the printing paper and the shred printing paper is discarded.
