Abstract
A gear train assembly comprises a gear train and a motor to drive the gear train. A shaft which is driven by the gear train, a rubber roller engaging the shaft and being co-axial therewith. The gear train also comprises a roller gear disposed on the shaft. The roller gear disengages from a second gear that drives the shaft or the rubber roller in response to pulling of media from the peripheral containing the gear train.
Claims15
A gear train assembly for a media feeding peripheral device, comprising:
- a gear train;
- a motor to drive the gear train;
- a shaft which is driven by the gear train, a rubber roller that engages the shaft and is co-axial therewith;
- and,
- a roller gear disposed on the shaft;
- wherein the roller gear is to disengage from a second gear that drives the shaft or the rubber roller in response to an external force applied to a media from the peripheral device containing the gear train.
A gear train assembly for a media feeding peripheral device, comprising:
- a roller gear disposed on a shaft having a roller;
- wherein in a first direction of rotation of the roller gear, the roller gear is to drive rotation of the roller;
- wherein in a second direction of rotation of the roller, one of the roller gear or the roller is to laterally move away from the other of the roller gear or the roller so as to disengage.
A gear train assembly for a media feeding peripheral device, comprising:
- a motor which drives motion of a gear train;
- a shaft which is driven by the gear train;
- a roller disposed on the shaft;
- wherein the motor is to drive rotation of the gear train, the shaft, and the roller in an operational rotational direction;
- and,
- wherein in response to an external force applied to pull media from the peripheral device, to rotate a second gear and force a roller gear laterally and disengage from the roller second gear.
