Abstract:
A paper-loading mechanism for a document duplicating machine, said paper-loading mechanism being driven by a reciprocating part of a document duplicating machine to perform a periodical paper-loading control on a paper loader of the document duplicating machine, and comprising:an actuating unit, to provide a reciprocating motion for the paper-loading mechanism, the actuating unit is pushed by the reciprocating part along a line parallel and adjacent to one end of the trajectory of the reciprocating part and comprises:a sliding block, which is driven by the reciprocating part;a rack, which is fixed to one side of the sliding block, with its longitudinal direction to parallel to the trajectory of the reciprocating part; anda driven gear, which is meshed with the rack and is the output of the actuating unit;a transmitting unit, which is connected with the driven gear of the actuating unit and is used to transfer the reciprocating motion from the actuating unit to a paper-feeding pushrod;wherein the paper-feeding pushrod is located along one side of the paper loader of the document duplicating machine and is rotatable along its own longitudinal central axis, the paper-feeding pushrod also comprises a base plate fixed along the longitudinal surface, with one end of the paper-feeding pushrod being connected with a torsion spring, and the base plate extending to a bottom of the paper loader;further wherein the torsion spring is constructed to store a torsion energy and drive the paper-feeding pushrod smoothly, with one end of the torsion spring being connected with the paper-feeding pushrod and another end connected with the transmitting unit.
