Abstract To provide a crushing apparatus capable of deleting secret contents while leaving a fiber for a long time.SOLUTION: A crushing apparatus includes a rotary cutter portion that tears a fiber-containing sheet in a first direction, a roller portion sandwiching the fiber-containing sheet, and a tearing portion that is provided with the rotary cutter portion and the roller portion, and has a plurality of blades tearing the filter-containing sheet in a second direction intersecting the first direction. The rotary cutter portion has a first rotary shaft member rotating about a first axis, a second rotary shaft member reversely rotating in the opposite direction to the first rotary shaft member about a second axis parallel with the first axis, a plurality of first rotary cutters provided on the first rotary shaft member and rotating with the first rotary shaft member, and a plurality of second rotary cutters provided on the second rotary shaft members, and rotating with the second rotary shaft member. The first rotary cutter and the second rotary cutter are separated from each other.SELECTED DRAWING: Figure 1 【課題】繊維を長く残しつつ、機密内容を抹消することができる粗砕装置を提供する。【解決手段】繊維含有シートを第1方向に引きちぎる回転カッター部と、繊維含有シートを挟むローラー部と、前記回転カッター部と前記ローラー部との間に設けられ、繊維含有シートを前記第1方向と交差する第2方向に引きちぎる複数の刃を有する引きちぎり部と、を含み、前記回転カッター部は、第1軸を中心として回転する第1回転軸部材と、前記第1軸と平行な第2軸を中心として、前記第1回転軸部材と逆回転する第2回転軸部材と、前記第1回転軸部材に設けられ、前記第1回転軸部材とともに回転する複数の第1回転カッターと、前記第2回転軸部材に設けられ、前記第2回転軸部材とともに回転する複数の第2回転カッターと、を有し、前記第1回転カッターおよび前記第2回転カッターは、互いに離間している、粗砕装置。【選択図】図1
