Image reading apparatus

An image reading apparatus comprising:

• an insertion port for a medium;
• a medium placement portion that is displaceable between an opening position at which the insertion port is open and an accommodation position at which the insertion port is closed by at least a portion of the medium placement portion being accommodated in the insertion port, the medium placement portion being configured such that the medium inserted from the insertion port is placed on a placement surface when the medium placement portion is located at the opening position;
• a feeding unit that feeds the medium placed on the placement surface in a feeding direction;
• a reading unit that reads an image of the medium fed by the feeding unit;
• and
• a guide member that is provided at a position facing the placement surface and guides the medium by bringing the medium into contact with a contact surface, wherein
• the guide member is displaceable between a first position and a second position, the first position being a position where the contact surface forms a first inclination angle with respect to the placement surface so as to form an acute angle that narrows in the feeding direction when viewed in a width direction intersecting the feeding direction, the second position being a position where the contact surface forms a second inclination angle with respect to the placement surface, and the second inclination angle being larger than the first inclination angle when viewed in the width direction, and
• the guide member moves from the first position to the second position as the medium placement portion moves from the opening position to the accommodation position, and moves from the second position to the first position as the medium placement portion moves from the accommodation position to the opening position.
