There is disclosed an electronic printing apparatus which prints images on sucessive individual film units held in a cassette. A carriage assembly which mounts the cassette can be driven by a driving mechanism in different directions and at different speeds in response to a coupling mechanism being actuated by an actuator assembly. The acutator assembly includes a coil spring which is wrapped on a lead screw of the driving mechanism for actuating a coupling member of the coupling mechanism.
