Abstract: A medium ejection apparatus includes a housing, an ejection roller, and an ejection tray attached to the housing to be able to rotate and having a first surface and a second surface, formed at a back side of the first surface, to stack the medium ejected by the ejection roller. The first surface and the second surface are formed by a single member. The first surface is formed with a first recessed part extending in a medium ejection direction and a first beam part extending in the medium ejection direction and sticking out from the first recessed part. The second surface is formed with a second recessed part extending in the medium ejection direction due to the first beam part and is formed with a second beam part extending in the medium ejection direction and sticking out from the second recessed part due to the first recessed part.

Abstract: A medium conveying apparatus includes a conveying roller to convey a medium, a first magnet to generate a first magnetic force for attracting a magnetic material moving with the medium conveyed by the conveying roller, and a second magnet to generate a second magnetic force for attracting the magnetic material attracted to the first magnet.

Abstract: A medium conveying apparatus includes a first roller, a second roller located to face the first roller, to hold and convey a medium with the first roller, a drive shaft to rotate the second roller, a motor to rotate the drive shaft, and a joint to connect the second roller and the drive shaft. The joint is configured to keep connecting the second roller and the drive shaft when the second roller moves in a vertical direction. The drive shaft is located at an intermediate position between a first position where the second roller is in contact with the first roller and a second position where the second roller separates most from the first roller in the vertical direction. A distance between the second position and the intermediate position is greater than a radius on cross section of the second roller in the vertical direction.

Abstract: A sheet feeding apparatus includes a feeding unit capable of feeding a sheet-like medium, plural speed detecting units capable of respectively detecting a speed of the medium fed by the feeding unit, at plural positions along a width direction of the medium orthogonal to a feeding direction of the medium, and a bound-medium detecting unit capable of detecting the medium having a part thereof bound with another one of the medium, based on the speed detected respectively by the speed detecting units.
