A roller driving apparatus of a laminator includes a pair of supporting frames facing each other, upper and lower rollers formed between the supporting frames, upper and lower roller gears coupled with one end of the roller passing through one supporting frame to transfer rotational force to the roller and meshed with each other, connection gear selectively coupled to either the upper roller gear or the lower roller gear to transfer rotational force, motor disposed outside the one supporting frame and to which motor is fixed, motor gear fixed to rotational shaft of the motor, for selectively transferring the rotational force of the motor to the connection gear, manipulating means for manipulating transfer state of the rotational force from the motor gear to either the upper gear or the lower roller gear by moving the connection gear using external force of user, and fixing means for fixing manipulated location.
