Abstract: A paper feeder comprises a control unit; a pair of side plates; a feed module having two or more separate feed rollers; a transport module having two or more separate transport rollers; a pusher module having a belt assembly and at least one pusher roller disposed under the belt assembly, the belt assembly further having two or more parallel shafts and two or more belts each having a protrusion and fitted on the shafts, the protrusions corresponding to each other; a first driving mechanism having a first motor and a first transmission mechanism, the first motor being connected to the first transmission mechanism which is in turn connected to at least one of the feed rollers; a second driving mechanism having a second motor and a second transmission mechanism, the second motor being connected to the second transmission mechanism which is in turn connected to at least one of the pusher rollers; a third driving mechanism having a third motor and a third transmission mechanism, the third motor being connected to

Abstract: A self mailing apparatus comprises a pair of spaced main side plates; a feeder module for feeding a stack of media being mounted between the main side plates; a registration roller module disposed in front of the feeder module; a tabbing mechanism disposed in front of the feeder module and being pivotably about a pair of first pivot axes rotatably disposed on the main side plates; a labeling mechanism disposed in front of the tabbing mechanism and being pivotably about a second pivot axis rotatably disposed between the main side plates; a media transport mechanism comprising a first roller module disposed in front of the feeder module, a second roller module disposed below the tabbing mechanism, and a third roller module disposed below the labeling mechanism; a first driving means for driving the feeder module and the registration roller module; a second driving means for driving the tabbing mechanism; a third driving means for driving the labeling mechanism; and a fourth driving means for driving the media t

Abstract: A bottom feeding mechanism comprises a feed roller assembly and a conveyor belt assembly functioning as a first stage gate and a set of snubber rollers functioning as a second stage gate. The feed roller assembly comprises a pair of feed rollers fixed on a shaft rotatably mounted on feeding bases and the conveyor belt assembly is situated in between the feed rollers and above the feed roller shaft. Apexes of the feed roller and the conveyor belt define the medium passage. The feed roller and the conveyor belt can only move unidirectionally, which are controlled by a driving means through one-way clutches. The snubber rollers are rotatably mounted on a bracket in an overlapping relation, i.e. one is over the other. Each snubber roller is independently driven. The upper snubber roller is driven by a torque-limited slip clutch device.
