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

An image reading apparatus, comprising:

• a reading portion configured to read an image formed on a sheet;
• a placing portion on which a sheet is placed;
• a conveying member configured to convey the sheet placed on the placing portion;
• a first guide member configured to restrict a movement of an end portion of the sheet placed on the placing portion in a sheet width direction which is orthogonal to a conveying direction of the sheet;
• a second guide member configured to restrict a movement of the other end portion of the sheet placed on the placing portion in the sheet width direction;
• and
• a moving portion, wherein when one guide member of the first guide member and the second guide member is moved in the sheet width direction, the moving portion moves the other guide member of the first guide member and the second guide member in a direction opposite to a direction in which the one guide member is moved while being interlocked with a movement of the one guide member in a first area of a moving area, and the moving portion allows the one guide member to be moved without being interlocked with a movement of the other guide member in a second area of the moving area.

An image forming apparatus, comprising:

• an image forming portion configured to form an image on a sheet;
• a placing portion on which a sheet is placed;
• a conveying member configured to convey the sheet placed on the placing portion;
