To suppress a wear of a component, and to improve the durability of a device.SOLUTION: In a metal piece recovery device 7, a recovery roller 72 is rotation-driven along a floor surface. A recovery magnet portion 71 is composed of a plurality of magnets, is disposed in the recovery roller 72, generates an attraction magnetic field 7a that magnetically attracts a metal piece in a first area including an area opposite to the floor surface on an outer periphery of the recovery roller 72, and forms a secession area 7b that secedes the metal piece from an outer peripheral surface of the recovery roller 72 in a second area other than the first area on the outer periphery of the recovery roller 72. The metal piece storage portion 73 stores the metal piece seceded from the outer peripheral surface of the recovery roller 72.SELECTED DRAWING: Figure 1 【課題】部品の摩耗を抑制し、装置の耐久性を向上すること。【解決手段】金属片回収装置７において、回収ローラー７２は、床面に沿って回転駆動される。回収磁石部７１は、複数の磁石からなり、前記回収ローラー７２内に配置され、前記回収ローラー７２の外周における前記床面に対向する領域を含む第１領域において金属片を磁気的に引き付ける吸引磁界７ａを発生させ、前記回収ローラー７２の外周における前記第１領域以外の第２領域において前記金属片を前記回収ローラー７２の外周面から離脱させる離脱領域７ｂを形成する。金属片収容部７３は、前記回収ローラー７２の外周面から離脱した前記金属片を収容する。【選択図】図１
