Abstract
A roller unit includes: a first roller including, at one end, a shaft having a cut-out portion; a bearing that supports the shaft and forms a space for accommodating an object disposed in the cut-out portion; and a switching member including a shaft part that can be disposed in the cut-out portion, and a separating part that is continuous with the shaft part and that, when the shaft part is disposed in the cut-out portion, comes into contact with a unit including a second roller to separate the first and second roller. When the shaft part rotates with the shaft and moves from the cut-out portion to the space, the separating part comes out of contact with the unit, bringing the first roller and the second roller into a state in which the first roller and the second roller push each other.
