Patent ID: 7013945

Claim:
A roller driving apparatus of a laminator comprising: a pair of supporting frames facing each other; upper and lower rollers formed between the supporting frames; upper and lower roller gears coupled with each one end of the upper and lower rollers passing through one supporting frame, for transferring rotational force to the upper and lower rollers, wherein the upper and lower roller gears are meshed with each other; at least one connection gear selectively coupled to either the upper roller gear or the lower roller gear, for transferring rotational force; a motor fixing means disposed outside the one supporting frame, for fixing a motor; a motor gear fixed to a rotational shaft of the motor, for selectively transferring the rotational force of the motor to the connection gear; a manipulating means disposed between the one supporting frame and the motor fixing means, for manipulating a transfer state of the rotational force from the motor gear to either the upper roller gear or the lower roller gear by moving the connection gear using an external force of the user, wherein a center of the connection gear is coupled to the manipulating means; and a fixing means for stably fixing the manipulating means.
