主权项 1. A sheet conveying apparatus, comprising: a conveying roller pair including a first conveying roller and a second conveying roller, which conveys a sheet by a nip portion formed by the first conveying roller and the second conveying roller; a shutter portion which is rotated around a rotation center of a rotary shaft of the first conveying roller, the shutter portion being rotated and guiding a leading edge of the sheet to the nip portion after the leading edge of the sheet conveyed toward the nip portion abuts against the shutter portion; an abutment portion, provided in the shutter portion, against which the leading edge of the sheet is abutted; and a guide portion disposed opposite to the shutter portion, the guide portion being coaxially adjacent to the second conveying roller and having an outer circumferential surface which is the same as a roller surface of the second conveying roller in the nip portion, the guide portion being fixed to the sheet conveying apparatus to guide the leading edge of the sheet to the nip portion when the shutter portion is rotated by abutting the leading edge of the sheet against the abutment portion.
