Abstract:
1. A transmission device for plotters comprising a single freely rotating first wheel ( 2 ) arranged to simultaneously contact the motor tube ( 5 ) and the winder tube ( 6 ) of a plotter, such that the rotation of the motor tube ( 5 ) is transmitted to said winder tube ( 6 ) through only said freely rotating first wheel ( 2 ), wherein the single freely rotating first wheel ( 2 ) is unconnected to a motor other than the motor tube, and capable of being rotated clockwise or counterclockwise; and, wherein the freely rotating first wheel ( 2 ) slides relative to motor tube ( 5 ) or winder tube ( 6 ) when the winder tube ( 6 ) has a different rotational speed than the motor tube ( 5 ).
