ABSTRACT:
A perforator includes a perforating unit, a chad recovery/delivery unit, a chad storage unit, a chad guiding unit, and a shielding unit. The perforating unit perforates a sheet-shaped recording medium. The chad recovery/delivery unit delivers a chad perforated by the perforating unit to the chad storage unit via discharge channels in the chad guiding unit. The chad storage unit stores the delivered chad. The shielding unit includes a shielding body and a shielding face fixed on an end thereof. The shielding unit releases a shielding against the discharge channels to discharge the chad though an opening in an interior of the shielding body to the chad storage unit when the shielding unit is in a first position. When the shielding unit is in a second position, the shielding face blocks the discharge channels to prevent the chad from being discharged to the chad storage unit.
