  • Publication number: 20230406652
    Abstract: A sheet supply device includes a cassette, a housing, a first roller, and a first rib. The cassette is capable of accommodating a sheet. The housing movably supports the cassette in a first direction. The first roller is supported by the housing. The first roller is rotatable about a rotation axis parallel to a second direction orthogonal to the first direction. The first roller includes a pair of flanges spaced apart from each other in the second direction. The first rib protrudes downward from the cassette. The first rib has a lower end surface in contact with the first roller between the pair of flanges. The first rib extends in the first direction. The first rib has a first width of a first portion in the second direction wider than a second width of a second portion in the second direction. The first portion is disposed between the pair of flanges in a state where the cassette is accommodated in the housing.

  • Patent number: 11820623
    Abstract: A sheet conveying device includes an aligning roller and a sheet guide. The aligning roller is configured to rotate in a forward direction along a sheet conveying direction, and stop rotation or rotate in a reverse direction to align a sheet conveyed thereto with a nip formed with the aligning roller. The sheet guide is disposed along a sheet conveyance path extending to the nip in the sheet conveying direction, and movable between a first position at which the sheet conveyance path has a first width in a thickness direction of the sheet and a second position at which the sheet conveyance path has a second width in the thickness direction less than the first width. The sheet guide is at the first position when the aligning roller stops rotation or rotates in the reverse direction and at the second position when the aligning roller rotates in the forward direction.

  • Patent number: 11795028
    Abstract: According to one embodiment, a sheet processing apparatus includes a folding unit, a fold reinforcing unit, and a control unit. The folding unit folds a sheet and forms a fold line thereon. The fold reinforcing unit includes a fold reinforcing roller. The fold reinforcing roller sandwiches the fold line on the sheet formed by the folding unit and moves in a fold-line direction in which the fold line extends. The control unit moves the fold reinforcing roller from a first position close to a first end of the fold line on a first side in the fold-line direction to a second position close to a second end of the fold line on a second side opposite to the first side. The control unit can execute, at this time, a division movement mode including a reversal return operation.
