Abstract

The present invention relates to transmission device for plotters characterized in that it comprises at least a freely rotating first wheel (2) 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) through said freely rotating first wheel (2). It may also comprise a pair of freely rotating wheels (3) 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 having to use tools, and it achieves a clutch effect as the result of the sliding of the wheels with respect to the tubes.

Claims

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).

2. The transmission device according to claim 1, further comprising a pair of freely rotating wheels (3) 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).

3. The transmission device according to claim 1, wherein said first wheel (3) is arranged at one end of said transmission device, and said pair of wheels (3) are arranged to the other end of said transmission device.

4. The transmission device according to claim 3, comprising a pair of shafts (4) located at the ends of the transmission device on a side of a plate (1) which is opposite said wheels (2, 3) are located for direct transmission or inverse transmission.

5. The transmission device according to claim 2, wherein said first wheel (2) is arranged at one end of said transmission device, and said pair of wheels (3) are arranged at the other end of said transmission device.

6. The transmission device according to claim 5, comprising a pair of shafts (4) located at the ends of the transmission device on a side of a plate (1) which is opposite to a side of the plate (1) where said wheels (2, 3) are located for direct transmission or inverse transmission.
