A base for operative association with an operating mechanism sensitive to horizontal vibration, such as an ink jet printer, supports a horizontal document feeder plate and associated drive operative to advance documents in sequential fashion from a stack toward the operating mechanism. A drive linkage interconnects a rotatable drive shaft to the feeder plate to effect horizontal reciprocating movement thereof. A counterweight is associated with the drive so as to substantially offset or nullify horizontal inertia forces imparted to the base by the feeder plate whereby to minimize horizontal vibration of the base. In an embodiment utilized for intermittent feeding of documents to the operating mechanism, a balance arm and associated counterweight cooperate with the feeder plate to offset horizontal inertia forces imparted to the base, and also minimize start-up torque required to initiate reciprocating movement of the feeder plate after stoppage.
In apparatus including a base operatively associated with operating means sensitive to horizontal vibration of the base, and article feeder means including a transfer member movable between a first position and a second position;
In apparatus including a base operatively associated with operating means sensitive to horizontal vibration of the base, and article feeder means including a transfer member movable between a first position and a second position;
In apparatus including a base defining an elevated support surface, operating means operatively associated with said support surface and defining a work station, said operating means being of the type sensitive to horizontal vibration, and article feeder means supported by said base for feeding articles to said work station, said feeder means including a transfer member moveable between a first position operative to receive an article thereon and a second position operative to move the article toward said work station;
