摘要： 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.

摘要翻译：用于与水平振动敏感的操作机构（例如喷墨打印机）操作关联的基座支撑水平文件馈送板和相关联的驱动器，其可操作以从堆叠向操作机构顺序地推进文档。驱动连杆将可旋转驱动轴与供给板互连，以实现水平往复运动。配重与驱动器相关联，以便基本上偏移或消除由馈送板赋予基座的水平惯性力，从而使底座的水平振动最小化。在用于将文件间歇地馈送到操作机构的实施例中，平衡臂和相关联的配重与进给器配合以抵消施加到基座的水平惯性力，并且还最小化启动进给器的往复运动所需的启动扭矩板块停止后
