A cutting apparatus includes a housing formed with an insertion hole, a transfer unit configured to transfer an object inserted through the insertion hole, a reading unit configured to read an image of the object, a platen located opposite the reading unit, and a cutting unit. The reading unit includes a light-transmitting plate. The housing encloses the reading unit, the transfer unit, the platen and the cutting unit. The platen includes a part openable and closable so that a surface of the light-transmitting plate is externally exposed. The platen includes a first platen having a flat surface and a second platen which has a flat surface and is opposed to the surface of the light-transmitting plate and is openable and closable. The second platen is engaged with the first platen so that the flat surface of the second platen is flush with the flat surface of the first platen.
