The invention concerns to a device for exposing light-sensitive material, such as photographic paper. The apparatus includes an exposure device (15), an exposure stage (10), at least one magazine (2) for storing a roll of light-sensitive material, a transport device (8) for transporting the light-sensitive material from the magazine (2) to the exposure stage (10) and a cutting device (6) for cutting the light-sensitive material into single sheets. To be able to provide a larger selection of light-sensitive materials for exposing, a cassette (4) for storing light-sensitive material in the form of sheets is provided in the apparatus in addition to the roll magazine (2). A transfer device (11) transfers the sheet material from the cassette (4) to the transport device (8) or directly to the exposure stage (10).
