Abstract
A sheet loader includes a sheet loading part and a sheet length detector. The sheet loading part has a loading face on which a sheet is loaded. The sheet length detector is provided to the sheet loading part to detect a length of the sheet by obtaining information whether the loading face either contacts or approaches a surface of the sheet disposed facing the loading face at a given position on the loading face in a sheet conveying direction of the sheet loading part. The sheet length detector includes multiple projections retreatably extending outward beyond the loading face of the sheet loading part, and a projection retreating detector detecting whether the multiple projections are retreated under the loading face. At least one of the multiple projections is disposed closer to an upstream end of the sheet loading part than the other.
