Abstract
A paper feed assembly is disclosed whereby a single driver is used to both engage a paper to be acted on, move or feed the paper to a pre-determined area, and then retract so that the paper may be acted on. The paper feed assembly according to the present invention comprises a motor, a cage, a gear train, and a roller arm. The paper feed assembly being design to permit the motor to rotate in a first and a second rotation and to engage or retract from the paper in response to the first or the second rotation.
Claims20
A paper feed assembly comprising a motor, a roller arm, a gear train, and an assembly frame;
- said roller arm further comprising a drive roller, a driven roller, and a belt interconnecting the two rollers;
- wherein said motor has a first rotation which corresponds to a first signal input and a second rotation which corresponds to a second signal input;
- wherein said roller arm has a first travel direction and a second travel direction induced, at least in part, by the motor's first rotation and second rotation, wherein the drive roller has a first travel rotation and a second travel rotation induced, at least in part, by the motor's first rotation and second rotation, and wherein the assembly frame is configured for assembling the motor, the roller arm, and the gear train thereon.
A paper feed assembly comprising a cage and mounted to the cage are a roller arm, a motor having a motor rotation, and a gear train for transferring the motor rotation to the roller arm from one position to a second position, said roller arm further comprising a drive roller, a driven roller and a belt, and wherein said two rollers and said belt are configured to rotate as a consequence of the motor rotation.
A method for moving a paper form into position for printing by a print head, said method comprising:
- sending a first signal to a motor to turn a motor shaft in a first rotation, said motor shaft being coupled to a worm;
- turning a wormgear with said worm, said wormgear comprising a wormgear shaft;
- moving a roller arm in a first direction by action of the wormgear shaft;
- said roller arm comprising a drive roller, a drive roller, and a belt;
- frictionally engaging a paper form by said belt and then rotating said belt in a first belt direction to thereby move the paper form into a paper print position;
- and
- sending a second signal to the motor to turn the motor shaft in a second rotation;
- said second rotation causing the roller arm to move in a second direction, and wherein said second direction causes the roller arm to be spaced apart from the paper form.
