Sheet conveying apparatus, image reading apparatus, and image forming apparatus

An image reading apparatus, comprising:

• a sheet conveyance section configured to convey a sheet in a sheet conveying direction;
• a roller pair unit configured to nip and convey the sheet, and to warp the sheet in a case where a leading end of the sheet conveyed by the sheet conveyance section comes into contact with the roller pair unit;
• a first guide configured to oppose a first side of the sheet and to guide the sheet;
• a second guide configured to oppose a second side of the sheet that is opposite to the first side;
• a movable guide including an upstream portion extending upstream in the sheet conveying direction with respect to the nip portion and a downstream portion extending downstream in the sheet conveying direction with respect to the nip portion, wherein the movable guide is configured to oppose the first side of the sheet and to be movable in such a manner that, in a case where the movable guide moves, the downstream portion of the movable guide moves closer to or away from the second guide;
• and
• an image reading device configure to read an image on the sheet conveyed by the roller pair unit.
