Zusammenfassung:To provide a shredder which can separate overlapped sheet materials and can supply the separated sheet materials to a shredding unit.SOLUTION: A shredder includes a shredding unit, a mounting unit 3, and a supply unit 2 for bringing a supply roller 211 into contact with a sheet material on a mounting surface 311 of the mounting unit 3 and supplying the sheet material to a supply passage to the shredding unit. The supply roller 211 is arranged above the supply path and is rotatably supported around a rotary driving shaft 213 for rotating and driving the supply roller 211. Separation means 7 is provided between the shredding unit and the supply unit 2. The separation means 7 includes a plurality of first separation means 71 having first contact parts 711, and second separation means 73 having a second contact part 731 movable to the mounting surface 311. The first contact part 711 and the second contact part 731 are inclined so as to form an obtuse angle with the mounting surface 311, and the second contact part 731 has a resistance part 731a.SELECTED DRAWING: Figure 6 【課題】重なり状態のシート材を分離して細断ユニットへ供給することができるシュレッダを提供する。【解決手段】シュレッダは、細断ユニット、載置ユニット3、載置ユニット3の載置面311上のシート材に供給ローラ211が当接して細断ユニットへの供給路に供給する供給ユニット2を備え、供給ローラ211は、供給路の上方に配され且つ供給ローラ211を回転駆動するための回転駆動軸213周りに回動可能に支持され、分離手段7が細断ユニットと供給ユニット2の間に設けられ、分離手段7は、第1当接部711を有する複数の第1分離手段71と、第2当接部731を載置面311に対して移動可能に有する第2分離手段73とを含み、第1当接部711および第2当接部731は、載置面311に対して鈍角をなすように傾斜し、第2当接部731は抵抗部分731aを有する。【選択図】図6
