TRANSMISSION DEVICE FOR PLOTTERS

摘要

The transmission device for plotters is characterised in that it includes at least a first wheel (2) turning freely that is arranged between 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) via said freely turning first wheel (2). It may also include a pair of wheels (3), that turn freely and that are constrained to rotate together by contact, arranged between said motor tube (5) and said winder tube (6), one wheel of said pair of wheels (3) being in contact with said motor tube (5) and the other wheel of said pair of wheels (3) being in contact with said winder tube (6). It facilitates the change from direct to inverse transmission, without requiring the use of tools, and it achieves a clutch effect through the sliding of the wheels in relation to the tubes.
