Image reading apparatus with movable apparatus body

An image reading apparatus comprising:

• a support portion in contact with a mount surface on which the apparatus is mounted;
• an apparatus body portion that includes a reading sensor that reads an original, the apparatus body portion being provided so that a position thereof is changeable by being rotated relative to the support portion;
• and
• a discharge tray provided so as to be openable/closeable by being rotated relative to the apparatus body portion, the discharge tray, by being open, receiving the original discharged from the apparatus body portion, wherein
• the apparatus body portion is switchable between
• a first position that is a position while not in use, and
• a second position that is a position of the apparatus body portion when reading of the original with the reading sensor is performed and that is a position in which a projected area of the apparatus body portion on the mount surface is larger than that of the first position, and
• when the apparatus body portion is in the first position and when the discharge tray is opened from the closed state, the discharge tray abuts against the support portion and applies force to the apparatus body portion in a direction that switches the apparatus body portion from the first position to the second position to switch the apparatus body portion from the first position to the second position.
