Image reading apparatus

An image reading apparatus attached to a printing apparatus and configured to read an image from a medium from which an image is to be read, the image reading apparatus comprising:

• an enclosure;
• a placement section having a placement surface at which the medium is placed;
• a conveyer configured to convey the medium in a. predetermined conveyance direction;
• a first quide that is displaceable between a first state and a second state, the first state being a state in which the first guide is located at a housed position determined in advance as a position where the first guide is housed in the enclosure above the placement section, the second state being a state in which the first guide is located at a supporting position determined in advance as a position where the first guide cooperates with the placement section to support the medium;
• and
• an image reader configured to read an image from the medium conveyed by the conveyer,
• wherein the conveyance direction is, when viewed in a direction perpendicular to the placement surface, parallel to a direction in which the printing apparatus conveys a print medium, and
• the first quide in the second state inclines downward from upstream to downstream in the conveyance direction, and guides the medium conveyed by the conveyer to a position above an upstream end of the placement section in the conveyance direction or a position flush with the upstream end of the placement section in the conveyance direction.
