Exit shaft dampening device to improve print quality
View Patent ↗The present invention includes a damping device for a media feed mechanism for a peripheral device having a media feedpath having a feed shaft and a downstream exit shaft. In one form a damping hub is mounted on said exit shaft, a resilient biasing member extending between the damping hub and the feed shaft to create a damping force on the damping hub. In another embodiment damping is provided by a brake structure engaging said damping hub. In yet another embodiment, a brake structure is pivotably mounted.
1. A damping device for a media feed mechanism having a rotatable feed shaft and a rotatable exit shaft downstream of said feed shaft defining a media feedpath therebetween, comprising:
a damping hub mounted on said exit shaft; and
a resilient biasing member extending between said damping hub and said feed shaft to create a damping force on at least one of said damping hub and said feed shaft.
2. The media feed mechanism of claim 1 wherein said damping hub is formed of a preselected diameter.
3. The media feed mechanism of claim 1 further comprising at least one exit roller on said exit shaft.
4. The media feed mechanism of claim 3 further comprising a plurality of exit rollers.
5. The media feed mechanism of claim 1 further comprising a stationary component disposed between said feed shaft and said exit shaft with said resilient biasing member engaging said stationary component.
6. The media feed mechanism of claim 5 wherein said stationary component comprises a motor disposed between said damping hub and said feed shaft.
7. The media feed mechanism of claim 6 wherein said resilient biasing member elastically bends around said motor.
